Breathing air, air. oxygen helps us breath. we need trees for oxygen. so whe need trees and plants to survive.
Nitrogen makes up about 78% of the air we breathe, with oxygen making up around 21%.
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
To determine the density of an element, you would need to measure its mass and volume. The density of an element is calculated by dividing its mass by its volume. The formula for density is: Density Mass / Volume. By measuring the mass and volume of the element, you can then calculate its density.
that would be oxygen
if you want to breath obviously you need oxygen and hydrogen
We breathe in oxygen.
Oxygen
Carbon Dioxide
No. This is impossible because we breath it in.
yes because air is used to make out ok oxygen which is an element for us to breath in.
