What causes valley air to move up surrounding mountains during the day?
AleksandrR [38]

Answer:

so the third one

Explanation:

During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed. During the night the slopes get cooled and the dense air descends into the valley as the mountain wind.

How many grams of NaOH are needed to make 0.250 liter of a 0.500 M solution of NaOH? 0.125 g 5.00 g 2.00 g
makkiz [27]

Answer:

5.00g

Explanation:

Molarity is moles per liter

Therefore:

x moles/.250L = .5 moles/1L

Solve for x: .125 moles required

Question asks for grams of NaOH so multiply the moles by the molar mass of NaOH

.125(39.997) = 4.999625g

Rounds to 5.00g

What effect does mass have on force and acceleration?
alisha [4.7K]

Answer:

___________________________________________________________

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

How many atoms are there in 8.08 moles of carbon dioxide
sertanlavr [38]

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms
