What is the percent composition of a compound with the empirical formula CO2?
The percent composition of a compound with the empirical formula CO2 is 27.3% carbon and 72.7% oxygen.
Which three gases make up 99.9 percent of the air?
co2, nitrogen and oxygen
Do plants give out oxygen?
I think when they receive carbon dioxide
What is the empirical formula for a compound that is 43.6 percent and 56.4 percent oxygen?
The empirical formula for the compound that is 43.6% carbon and 56.4% oxygen is CO2. This is because the ratio of carbon to oxygen in carbon dioxide is 1:2.
What proportion of the air is made up of carbon dioxide oxygen and nitrogen?
nitrogen is 78% while CO2 is part of a percent
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
Can plants create oxygen without the presence of CO2?
no as c02 is like oxygen for plants and we can not breathe out co2 without oxygen
Why does a person have to exhale?
Because air is made of of oxygen and co2, so you take in the oxygen and blow out the co2.
What the steps of the oxygen cycle?
oxygen is breathed in we use it co2 let out plants take co2 in cycle repeats
What is the percent composition of CO2?
Carbonic acid - H2CO3 Find the atomic masses of each element and multiply it by however many atoms are in the compound, then add them together. H = 1.007 × 2 = 2.014 C = 12.01 O = 16.00 × 3= 48.00 Molecular mass = 2.014 + 12.01 + 48.00 = 62.02 grams/mole Take the mass of a specific element (above) and divide it by the total molecular mass. Change the final answer to a percent Hydrogen: 2.014 ÷ 62.02 = .0325 = 3.25% Carbon: 12.01 ÷ 62.02 = .194 = 19.4% Oxygen: 48.00 ÷ 62.02 = .774 = 77.4% Carbonic acid contains 3.25% Hydrogen, 19.4% Carbon, and 77.4% Oxygen.
Do plants absorb oxygen along with CO2?
Plants primarily absorb carbon dioxide (CO2) during photosynthesis and release oxygen as a byproduct. They do not absorb oxygen in the same way that they absorb CO2. Oxygen is mainly taken in through plant tissues for respiration, where it is used to break down sugars and produce energy.
How do houseplants increase the amount of oxygen in your home?
Oxygen is a bi product of living plants. As the plant during light hours takes in co2 it releases oxygen. During the dark hours the plant does not use co2 but uses oxygen and produces co2.
