Answer:
8.48 × 10²² atoms of Nitrogen
Explanation:
Calcium Carbonate is an ionic compound made up to Calcium (Ca²⁺) and Nitrate (NO₃⁻) ions. Also, the subscript 2 after the closed bracket after NO₃ specifies that there are two moles of NO₃⁻ in calcium nitrate compound. Hence, in total we can say that this compound contain,
1 atom of Calcium
2 atoms of Nitrogen
6 atoms of Oxygen
Therefore,
When,
1 molecule of Ca(NO₃)₂ contains = 2 atoms of Nitrogen
Then,
4.24 × 10²² molecules of Ca(NO₃)₂ will contain = X atoms of Nitrogen
Solving for X,
X = 2 atoms × 4.24 × 10²² molecule / 1 molecule
X = 8.48 × 10²² atoms of Nitrogen
The process of osmosis separates the mixture by changing the state of the water and making it a gas. Changing states is a form of physical change.
Normally the systemic arterial blood has a pO₂ of about 75-100 mmHg, a pCO₂ of about 35-45 mmHg, and a pH of 7,35-7,45.
Answer:
Answer choice A
