What kind of weather is associated with a warm front? 9. What symbol on a map represents a warm front? 10. What symbol on a map represents a cold front? 11. What type of weather is associated with a stationary front? 12. How does an occluded front form? 13. What kind of weather can an occluded front bring? 14. What is the symbol on a map to show an occluded front?
Answer:
1. a body of air with horizontally uniform temperature, humidity, and pressure.
2. Boundaries between unlike air masses. Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties.
3. Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties.
4. Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot.
5. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.
6. an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry.
7. Commonly, when the cold front is passing, winds become gusty; there is a sudden drop in temperature, and heavy rain, sometimes with hail, thunder, and lightning.
8. stormy
9. The symbol that is used to identify a cold front on a weather map is a blue line with triangles that point in the direction in which the cold front is moving. The line is represents the leading edge of the cooler air mass.
10. The symbol that is used to identify a cold front on a weather map is a blue line with triangles that point in the direction in which the cold front is moving. The line is represents the leading edge of the cooler air mass
11. Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
12. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.
13. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.
14.An occluded front is a combination of those two signs. They are indicated on a weather map either by a purple line with alternating semicircles and triangles pointing in direction of travel, or by red semicircles and blue triangles pointing in the same direction.

Answer:
Heya
Explanation:
1) air mass:- An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture.
2) Air masses are characterized by their temperature and humidity properties.
3) ( same answer i.e. temperature and humidity properties).
4) Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical. Continental and superior air masses are dry while maritime and monsoon air masses are moist. Weather fronts separate air masses with different density (temperature or moisture) characteristics.
5) Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
6) Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry.
7) Commonly, when the cold front is passing, winds become gusty; there is a sudden drop in temperature, and heavy rain, sometimes with hail, thunder, and lightning. Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms.
8) Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.
9) The symbol that is used to identify a warm front on a weather map is a red line with half circles that point in the direction in which the warm front is moving. The line represents the leading edge of the warmer air mass.
10) On weather maps, the surface position of the cold front is marked with the symbol of a blue line of triangles/spikes (pips) pointing in the direction of travel.
11) Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
12)At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together. Occluded fronts usually form around areas of low atmospheric pressure.
13) The warm air mass rises as the cool air masses push and meet in the middle. The temperature drops as the warm air mass is occluded, or “cut off,” from the ground and pushed upward. Such fronts can bring strong winds and heavy precipitation. Occluded fronts usually form around mature low pressure areas.
14)Occluded fronts are drawn as a solid purple line with half circles and triangles pointing in the direction that the front is moving. An occluded front usually brings dry air.

The value of Kp for the reaction 2 A(g) + B(g) + 3 C(g) → 2 D(g) + E(g) is 18530 at a particular temperature. What would be the value of Kp for the reaction 2 D(g) + E(g) → 2 A(g) + B(g) + 3 C(g)?
Answer:
[tex]Kp2=5.3967x10^{-5}[/tex]
Explanation:
Hello there!
In this case, since the Kp for the first reaction is given, according to the following equilibrium expression:
[tex]Kp=\frac{p_D^2p_E}{p_A^2p_Bp_C^3} =18530[/tex]
However, since the second reaction stands for the reverse of the initial one, the equilibrium expression would be:
[tex]Kp_2=Kp=\frac{p_A^2p_Bp_C^3}{p_D^2p_E}[/tex]
And therefore its Kp the inverse of the aforementioned one:
[tex]Kp2=1/18530\\\\Kp2=5.3967x10^{-5}[/tex]

If you have 12 atoms of hydrogen before a chemical reaction, how many atoms of hydrogen will be present
Answer:
12 atoms of hydrogen will be present in the product
Explanation:
12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
The law of conservation states that the mass of the element remains the same during the course of the reaction.
The law of reaction conformed by the following:-
Mass of reactant Mass of productAccording to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms
Hence, the amount remains the same in the reaction that is 12 atoms

If you produce 10 g of water in the reaction from 20 g of O2 what is your percent yield? 2H2+O2>2H2O
Answer:
44.4%
Explanation:
The balanced chemical equation for the reaction is:
2 H₂(g) + O₂(g) → 2 H₂O(g)
According to the equation, 1 mol of O₂ produces 2 moles of water (H₂O). We convert the moles to grams by using the molecular weight (Mw) of each compound:
Mw(O₂) = 2 x 16 g/mol O = 32 g/mol
mass O₂ = 1 mol x 32 g/mol = 32 g O₂
Mw(H₂O) = (2 x 1 g/mol H) + 16 g/mol O = 18 g/mol
mass H₂O = 2 mol x 18 g/mol = 36 g H₂O
Thus, from 32 grams of O₂, 36 g of H₂O are produced (stoichiometric ratio= 36 g H₂O/32 g O₂). We calculate the amount of H₂O that would be produced from 20 grams of O₂ by multiplying the stoichiometric ratio by the mass of O₂, as follows:
36 g H₂O/32 g O₂ x 20 g O₂ = 22.5 g H₂O
The theoretical yield of H₂O is 22.5 g, and the actual amount produced is 10 g. So, we calculate the percent yield as follows:
Percent yield = actual yield/ theoretical yield x 100
= (10 g)/(22.5 g) x 100
= 44.4%

Which equation is correctly balanced?
A) CaO + 2H2O + Ca(OH)2
B) NH3 + 202 → HNO3 + H20
C) Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 3H2O
D) Cu + H2SO4 → CuSO4 + H2O + SO2
CaO + 2H2O + Ca(OH)2 is a balance chemical equation. Therefore, option A is correct.
What is balance chemical equation ?A balanced chemical equation is one that has the same number of atoms of each type in the reaction on both the reactant and product sides. In a balanced chemical equation, both the mass and the change are equal.
When a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants, according to the law of conservation of mass. As a result, the number of atoms in each element remains constant during the chemical reaction. As a result, the chemical equation must be corrected.
The chemical equation is said to be balanced if there are no inequalities. Every element in this example now has an equal number of atoms on both the reactant and product sides.
Thus, option A is correct.

What is the correct formula for the missing product from the equation below:
Na2CO3(aq)
+
CaCl2 (aq)
> NaCl +
Answer:
CaCO3 (s)
Explanation:
This equation is a double replacement equation, which means that since Na and Cl and paired, Ca and CO3 will be paired.
Then, you look at the charge of each element and balance
Ca has a 2+ charge
CO3 has a 2- charge
The 2+ charge and the 2- charge will cancel so there is no need for a subscript or to balance the equation
The complete equation will be Na2CO3 (aq) + CaCl2(aq) -> NaCl (aq) + CaCO3 (s)
