Answer:
Look at the periodic table of elements
Explanation:
Group 1 is the most reactive and to the right
Group 18 is least reactive and all the way to the left. The rest are in between. The groups go vertical.
You'd be able to solve with this information youre welcome
We can get the vapor pressure of the solution from this formula:
Pv(solu) = n P°v
when n is the mole fraction of toluene so we can get by substitution in this formula:
n = moles of toluene / (moles of cholesterol + moles of toluene)
= 5.4 / ( 0.99 + 5.4) = 0.85
so by substitution in vapor pressure formula:
∴ Pv(solu) = 0.85 *41 = 34.85 atm
A. The kinetic energy of gas particles is higher in hot food than in cold food.
Explanation:
The smell of a hot food moves faster than the smell of a cold food because the kinetic energy of gas particles is higher in hot food than in cold food.
Let us establish that the smell of the food perceived are gases from the food.
- Both hot food and cold food emits these gases that tinkers our olfactory nerves.
- Hot food produces a hot gas.
- The higher the temperature the more kinetic energy it possess.
- This makes the gases more dispersed and it spreads faster.
- The cold food produces gas at a lower kinetic energy.

A)
Because it does not contain exactly all the DNA in the cell and some cells don't have a nucleus٫ such as the red blood cells.
