CuCl2
IUPAC ID: Copper dichloride, Copper(II) chloride.
Start with the number of grams of each element, given in the problem.
Convert the mass of each element to moles using the molar mass from the periodic table.
Divide each mole value by the smallest number of moles calculated.
Round to the nearest whole number.
Answer:decomposition
Explanation:U go from 2 to 1
The answer is D because the air is made of nitrogen and oxygen. The reaction is endothermic.
Hope this helps you! :)
<span>This reaction produces carbon dioxide. Platinum is used in the catalytic converter in some automobiles. The main objective of a catalyst is to act as a substance that speeds up a reaction. However, it is imperative that it does this without being consumed in the reaction.</span>

Hello!</h2>
The answer is:
The new temperature will be equal to 4 K.
<h2>
Why?</h2>
We are given the volume, the first temperature and the new volume after the gas is compressed. To calculate the new temperature after the gas was compressed, we need to use Charles's Law.
Charles's Law establishes a relationship between the volume and the temperature at a gas while its pressure is constant.
Now, to calculate the new temperature we need to assume that the pressure is kept constant, otherwise, the problem would not have a solution.
From Charle's Law, we have:
So, we are given the following information:
Then, isolating the new temperature and substituting the given information, we have:
Hence, the new temperature will be equal to 4 K.
Have a nice day!
