As, overall order of reaction is 2 indicates the rate of reaction is only depending on concentration of A and its rate of reaction can be shown as:
R = K [A]^2
So, by increasing the concentration of A, the rate of reaction increases.
NH3 because the molecule in the room is more solid than and room temperature
Answer: In covalent bonds electrons are shared. In ionic bonds electrons move from one to another atom. but in Metallic bond, they move freely so the answer is C.
Answer:
geologists
Explanation:
they use acid test in order to determine if the sample is a carbonate.
From the chemical equation given, one mole of CH4 yields two moles of water (H2O). If all the methane gas that is 8.9 L is combusted then the volume of water produced is the number of moles H2O times the volume of the methane gas used up, that is 8.9 L × 2 = 17.8 L of water produced.
