Answer:
D. CF₄
Explanation:
The compound with this molecular geometry is Carbon tetrafluoride (CF₄)
Carbon tetrafluoride (CF₄) also known as Tetrafluoromethane, is known to be the simplest perfluorocarbon. The compound, tetrafluoromethane is the hydrocarbon methane has been perfluorinated. It useful as a refrigerant but known to be a greenhouse gas. Due to the nature of the carbon-flourine bond, it has very high bonding strength. Its bonds are known to be the strongest single bonds in organic chemistry.
Option D is the correct answer.
The answer is it shifts right. This could be explained by Le
Chatelier's principle. It states that that when a system experiences a commotion
(such as absorption, temperature, or heaviness variations), it will answer to reinstate
a new equilibrium state. This just means that if there is an energy added, the
reaction is trying to remove it again by going to the right.

Answer:
Molarity = 54.50 M
Explanation:
Molarity is defined as the number of moles of a solute in 1 liter of solution. It has mol/l unit.
Molar mass of glucose, C6H12O6 = (6*12) + (1*12) + (16*6)
= 72 + 12 + 96 = 180g/mol
Density of glucose solution = 1.03g/ml
Density in g/l = 1.03g/ml * 1ml/10^-3l
= 1030g/l
10.5% mass of glucose = 10.5/100 * 180
= 18.9g/mol
Molarity = density (g/l)/molar mass (g/mol)
= 1030/18.9
= 54.50 M

M(CH4)=16.0 g/mol
</span>30g CH4*1mol/16.0 g - mol of CH4
30g CH4*(1mol/16.0 g)*(2 mol H2O/1 mol CH4) =15 mol H2O
30g CH4*(1mol/16.0 g)*(2 mol H2O/1 mol CH4)*22.4L/1mol=84 L H2O as gas, but at STP water should be liquid,so
15 mol H2O*18g H2O/1 mol=270g of H2O
270g*1ml/1g= 270 ml =0.27 L of liquid water, in reality it should be like this,
but I do not know what people who created this problem wanted H2O as liquid or as gas
