How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.
Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

During spontaneous fission, a nucleus of 25498Cf can produce 11846Pd, four neutrons, and what other nuclide?
Answer: 52Te - Tellurium
Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.
In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.
The reaction spontaneous fission of Cf is represented below.
25498Cf ⇒ 11846Pd + 4n + X
The characteristics of each element of the equation are:
1) The element Cf has atomic mass 254 and atomic number 98.
2) Element Pd has atomic mass 118 and atomic number 46.
3) Neutron is represented as n, has no atomic number and atomic mass 1.
Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.
At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is
98 - 46 + 0 = 52
In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.
The other nuclide for the spontaneous fission is Tellurium (Te).

I hope I can help youAs per the following graph that best describes the linear inequality in two variables is included in a straight line.
The linear inequality divided the coordinates plane into two halves. Here one half represents the solution and the other the inequality. Hence the option A is correct. The inequality that is represented by the graph is 3x + 2y = 2, Hence option B is correct. The correct inequality for the shaded region is y <- x + 1, hence the option C is correct. The line and shade with the sign "<" means that they are broken and shaded up. Hence the option A is correct. The given graph consists of equation 2x - 5 where to find Y in order of the pairs that satisfy the inequality are (5,2) hence the option B is correct.Learn more about which of the following is best described.

1. A 4.00 L sample of air at 35 degrees C expands to 5.50 L when heated. What is
the new temperature, in degrees Celsius, of the air
Answer:
150.5 °C
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 4 L
Initial temperature (T₁) = 35 °C
Final volume (V₂) = 5.5 L
Final temperature (T₂) =?
Next, we shall convert 35 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T₁) = 35 °C
Initial temperature (T₁) = 35 °C + 273
Initial temperature (T₁) = 308 K
Next, we shall determine the final (i.e the new) temperature of air. This can be obtained as follow:
Initial volume (V₁) = 4 L
Initial temperature (T₁) = 308 K
Final volume (V₂) = 5.5 L
Final temperature (T₂) =?
V₁ / T₁ = V₂ / T₂
4 / 308 = 5.5 / T₂
Cross multiply
4 × T₂ = 308 × 5.5
4 × T₂ = 1694
Divide both side by 4
T₂ = 1694 / 4
T₂ = 423.5 K
Finally, we shall convert 423.5 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T₂ = 423.5 K
T₂ = 423.5 – 273
T₂ = 150.5 °C
Thus, the new temperature of the air is 150.5 °C
How much carbon dioxide will be formed if 12.5 grams of oxygen reacts with 7.2 grams of propane?
Answer:66 grams of Carbon Dioxide.
Explanation:
The common currency of chemistry is moles. So it is necessary to change the mass of propane to moles. Then write a balance equation so the moles of propane to moles of Carbon Dioxide. Finally moles of Carbon Dioxide must be changed to grams.
C 3 H 8 + 5 O 2 = =3 C O 2 + 4 H 2 O
This is the balance equation for the burning of propane in Oxygen.
From the equation it can be seen that 1 mole of propane makes 3 moles of Carbon Dioxide a ratio of 1:3
Convert 22 grams of propane to moles by dividing by the molar mass of propane.
3 x 12 = 36 grams
1 x 8 = + 8 grams
total = 44 grams/ mole.
22
44
= .5 moles of propane.
Using the ratio of 1:3 .5 = 3( .5) = 1.5 moles of Carbon Dioxide.
Now multiply 1.5 moles of Carbon Dioxide by the molar mass of Carbon Dioxide
1 x 12 = 12 grams
2 x 16 = +32 grams
total = 44 grams /mole.
1.5 moles x 44 grams/mole = 66 grams.

How would the reactivity of an element with one valence electron vary from an element with 8 valence electrons
Answer:
An element with 1only one valence electron is extremely reactive while an element with 8 valence electrons is very stable and does not react most of the times
Explanation:
Valency is the number of electrons in the outermost shell of the atom. It shows the ease with which elements react and combine with each other.
An element can take a maximum of 8 electrons in most of its outermost shells. As a matter of fact, the goal for its stability is to attain a structure with all 8 slots for electrons in its outer shell filled up. The element can either do this by adding or removing electrons.
The ease with which it adds or removes the electrons shows its reactivity. If it has only one electron to lose, (the valence electron) the element will be very reactive because this is relatively easier to do when compared with 2 electrons, three electrons, and so on. An element with 8 electrons in its outer shell is very stable and does not need to react anymore. an example of this is Neon and Argon.

What substance changed physically under all three condition? Copper Wire
What substance changed chemically under all three condition? Steel Wool
What evidence indicates a chemical reaction is occurring? New gases are produced; A phase change has occurred; A color change
Select the three answers that are examples of a chemical reaction. The mixing of an acid and base shows an increase in temperature; after baking bread there is a new odor or smell; when hair is bleached it changes to a lighter color
Which data supports this inference? Baking soda dissolving; A gas formed, creating bubbles
Which experiment best shows evidence of energy being released in a chemical reaction? Heat and light are given off when paper is burned
Which experiment likely resulted in the formation of a precipitate? Two solutions are mixed together and a yellow solid forms
The BEST evidence for a chemical reaction is the formation of a new substance.
Explanation:
2. When heat and light are being given off, energy is being released. Paper burning is a chemical reaction b/c when paper is burnt, it is a new substance and the act can't be undone.
3. When a yellow solid forms, that solid is the participate.
4. You will for sure have a chemical reaction if a new substance is created.
5. Copper wire changed physically b/c the copper wire can be returned to its original condition in all of these situations and no new substance was formed. Steel Wool changed chemically b/c it can't be returned to its original state under any condition and new substances were formed every time.
6. New substances formed indicate a chemical reaction. A color change also is an indication of a chemical reaction.
7. When a substance can't be turned into its original position or a new substance is produced, a chemical reaction occurred.
