The formula of Aldehyde is represented by <span>C2H4O. It has two atoms of Carbon, four atoms of hydrogen and one atom of oxygen. Aldehyde is an organic compound. It's organic because it contains carbon. It has a structure of R-CHO, that consists a carbonyl center bonded to R group and to hydrogen.</span>
First question. Applying ideal gas equation PV=nRT, P= 101.3 x 10³Pa = 1atm. therefore, 1 x 260 x 10^-3 = n x 0.082 x 294.( Temperature in kelvin=273+21). n = 0.01 moles. Volume of gas at STP= n x 22.4 = 0.01x22.4 = 0.224L. Hope this helps
1. Energy as particles can't move without kinetic (movement) energy
2. I think it's Diffusion and Active Transport
The answer is the second choice
Well, the only way you would get clouds is evaporation, a liquid to a gas. (Change of matter) the clouds would not turn into rain without percipitation, gas to water. (Change of matter.)
