Answer:
A; 
Explanation:
The best way to start solving this problem is to start with the molecule with the most atoms. Since there are 12 carbons on the left, you need 12 on the right so 12 would need to be placed in front of carbon dioxide. Also you need 22 hydrogens and in each molecule of water, there are two hydrogen molecules so you need 11 molecules of water. After balancing you find that you need 24 oxygen on the left so you place the coeffecient 12 in front of the oxygen molecule.

Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite: 
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :
The percentage of copper in an azurite is 55.31%.
Malachite: 
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:
The percentage of copper in an malachite is 57.48%.
<span>Decreasing the temperature will decrease the pressure of a gas inside a closed cubical container.
In a closed container, the Volume (V) is fixed and the no of mole of the gas(n) are also fixed. So, we write the gas equation : PV = nRT
Here, V,R and n are constants.
So, Pressure is directly proportional to the temperature. Thus, on increasing the temperature, pressure will increase and on decreasing the temperature, the pressure will decrease.</span>
