The  electron process makes water and ATP  and is sometimes  called Oxidative phosphorylation   because  it require oxygen.


<u><em>Explanation</em></u>

Oxidative  phosphorylation  is a process  that take place in the  mitochondria  during aerobic respiration.

This process  result to formation of ATP as a result of  transfer  of electrons  from NADH  or FADH2  to O2.

The electron transport  chain and ATP  synthesis  are mainly embedded  in the  inner mitochondrial  membrane.

Calculate the vapor pressure of a solution made by dissolving 11.1 g Ca(OH)2 in 1 102 g of water at 25 °C. Vapor pressure of pur
Levart [38]

Answer:

23.15 mmHg.

Explanation:

To solve this question you need to understand that part of Raoult's law in your Chemistry textbook. So, let us delve right into the solution of the question.

We are given parameters such as the mass of Ca(OH)2 to be = 11.1 grams, mass of solvent = 102 grams, the Vapor pressure of pure water= 23.76 mm Hg, temperature = 25°C and vapour pressure of the solution= ??.

The molar mass of Ca(OH)2= 74 g/mol.

The first thing to do is to find the number of moles of Ca(OH)2 and that of water from the formula below;

Mass/ molar mass = Number of moles.

===> Number of moles, n= 11.1/ 74.

Number of moles = 0.15 moles Ca(OH)2.

===> Number of moles, n= 102/ 18.

Number of moles, n= 5.67 moles of water.

Next, we add the two moles together to find the solvent mile fraction since vapour pressure is proportional to mole fraction.

Then;

0.15 + 5.67 = 5.82.

Therefore, 5.67/ 5.82= 0.97.

Hence the vapor pressure of a solution = 0.97 × 23.76.

vapor pressure of a solution = 23.15 mmHg.

The density of pure solid copper is 8.94 g/mL. What volume does 34 g of copper occupy?
patriot [66]

hey there ! :

Density = 8.94 g/mL

mass = 34 g

Volume = ??

Therefore:

D = m / V

8.94 = 34 / V

V = 34 / 8.94

V = 3.803 mL

Hope this helps!

How would a sandblasted rock differ from a rock that hasnt been sandblasted
KengaRu [80]
Sandblasted: More smooth because all the rough edges are "blasted" away. And slightly smaller because of the loss of the edges. 

Non-Sandblasted: Not smooth; rough.
