"The vapor pressure will decrease and the boiling temperature will increase." When sodium chloride is added to water, the vapor pressure above the resulting salt solution is less than the vapor pressure above the pure water, and the boiling point of the salt solution will be greater than the boiling point of pure water. This results from the introduction of salt molecules to water, in which the salt solution needs a higher temperature for the vapor pressure to be equal to the pressure of the atmosphere.
Answer:
3.89 kg P2O5 must be used to supply 1.69 kg Phosphorus to the soil.
Explanation:
The molecular mass of P2O5 is
P2 = 2* 31 = 62
O5 = 5 *<u> 16 = 80</u>
Molecular Mass = 142
Set up a Proportion
142 grams P2O5 supplies 62 grams of phosphorus
x kg P2O5 supplies 1.69 kg of phosphorus
Though this might be a bit anti intuitive, you don't have to convert the units for this question. The ratio is all that is important.
142/x = 62/1.69 Cross multiply
142 * 1.69 = 62x combine the left
239.98 = 62x Divide by 62
239.98/62 = x
3.89 kg of P2O5 must be used.
Explanation:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons
2,2,4-trimetilpentano is the answer.
