Answer:stainless steal
Explanation:
what happens when a low air pressure seytem meets a high air pressure
Answer:
The temperature of the air drops to below freezing. 2. The air moves to the low pressure system, creating wind. 3.The precipitation is removed from the air. 4. The air starts blowing in an easterly direction.
Explanation:
Answer:
The slightly inward moving air in low pressure causes air to converge and since it can't move downward due to the surface, the air is forced upward, leading to condensation and precipitation as discussed earlier. The opposite occurs with high pressure.

What types of matter have the property of density?
1.Everything except gasses have density.
2.Only heavy matter has density.
3.All solids, liquids, and gases have density.
4.Only solid matter has density.
Answer:
all solids, liquids and gases have density
The types of matter which property of density can be attributed with are;
.All solids, liquids, and gases have density.
Density can be regarded to as one of the characteristic property of a substance. The density of a substance expressed the relationship that the particular substance has with the mass of the substance as well as its volume which is how much space it takes up.The mass of a particular atoms, as well as how they are been arranged and their size, determine the density of a substance.Both solid , liquid as well as gas has density.For instance, density of water is 1000kg/cm^3Therefore, option C is correct.

Students observe that in the presence of sunlight, silver chloride (AgCl) will react and create chlorine gas (Cl2) and leave behind solid silver (Ag). Which of the following equations correctly models and balances this reaction and has the correct reaction type?
A. AgCl + sunlight → Cl2 + Ag (synthesis reaction)
B. 2AgCl + sunlight → Cl2 + 2Ag (decomposition reaction)
C. AgCl + sunlight → Cl2 + Ag (decomposition reaction)
D. 2AgCl + sunlight → Cl2 + 2Ag (synthesis reaction)
Answer:
(B) 2AgCl + sunlight → Cl2 + 2Ag (decomposition reaction) is correct option.
The chemical equation which correctly models and balances this reaction and has the correct reaction type is 2 AgCl + sunlight → Cl₂ + 2 Ag (decomposition reaction).
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

How many atoms of Cr are there?
Water waves are surface waves. The energy of the waves moves
Question 2 options:
only perpendicular to the motion of the wave.
both parallel and perpendicular to the wave.
only parallel to the motion of the wave.
Answer:
Explanation:
Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.
The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.
There is no change in temperature during a phase change as this energy is being used to make or break bonds between molecules.

How many atoms of H are there?
Answer:Explanation:
ther are 4
Answer:
First off, 3.4 / 342 = 0.01, not 0.001, so moles H = 0.22, not 0.022.
Then you multiplied the erroneous 0.022 x 6.022 x 10^22. Avogadro's number = 6.022 x 10^23, not 10^22! So your final answer should be 1.3 x 10^23 H atoms (choice B).
Your reasoning was right on, just a few math errors.
