How do you make CO2 in chemistry?
Carbon dioxide is produced whenever an acid reacts with a carbonate. This makes carbon dioxide easy to make in the laboratory. Calcium carbonate and hydrochloric acid are usually used because they are cheap and easy to obtain.

How many atoms of carbon are there in one molecule of carbon dioxide?
two atoms
We breathe out CO2 when we exhale. The chemical formula for carbon dioxide shows that carbon dioxide contains atoms of carbon (C) and oxygen (O). The subscript 2 on the O shows that there are two atoms of oxygen in each molecule of carbon dioxide. There is only one atom of carbon in each molecule of carbon dioxide.
Which 2 elements make up water?
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O.
What causes low CO2 levels?
Low CO2 Levels in Blood: Causes and Symptoms. Low carbon dioxide (bicarbonate) levels might be brought on by: Hyperventilation, aspirin or alcohol overdose, diarrhea, dehydration, or severe malnutrition. Liver or kidney disease, an enormous cardiac arrest, hyperthyroidism, or unrestrained diabetes.
What is a safe CO2 level?
The safe level of CO2 in the atmosphere is said to be around 350 parts per million (ppm), and the April 2019 measure was 411.91 ppm.
What effects does CO2 have on humans?
Exposure to CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions.
What is the current CO2 level?
The current CO2 concentration in the atmosphere is over 400 parts per million (ppm). This has grown about 46% since pre-industrial levels (~280 ppm) in the early 1800s.
