<span>D. not enough precipitation is the answer</span>
Looks correct but the second to last I would of put abiotic and biotic factors but I don’t know what’s right for you
Answer:
1.07×10²¹ molecules are needed to sound the alarm
Explanation:
Let's convert the mass of CO to moles, to determine the amount of molecules.
0.05 g . 1 mol / 28 g = 1.78×10⁻³ moles
Now we can determine the number of molecules with the NA
1 mol has 6.02×10²³ molecules
1.78×10⁻³ moles may have (1.78×10⁻³ . 6.02×10²³) / 1 = 1.07×10²¹ molecules
Answer:
C, A, D and B
Explanation:
Water evaporates from the surface of the oceans leaving behind salts. As water vapor rises, it collects and is stored in clouds.
As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.
Condensation creates precipitation. Precipitation includes rain, snow, hail and sleet. The precipitation allows the water to return again to the Earth's surface.
When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater.
