<span>We breathe around an average of 500 ml of air in 1 normal (or relax) breathing. The lungs already have around 3 litres of reserve breathing. Since there is around 21% oxygen in air, we breathe in around 105 ml of Oxygen from the air. That is equal to around 0.14 g of Oxygen.</span>
<span>To find the amount of heat energy required to raise a substance by a certain number of degrees, we simply multiply: (specific heat * change in temperature * mass)
Heat = 2.22 * 35 * 3 = 233.1 joules
Therefore, we would need 233.1 joules of heat to raise the temperature by 3 degrees Celsius.</span>
Answer:
Just to let you know you are a good person
Yes, on one end of an amino acid is an amino group and on the other is a carbonyl group. There is also a hydrogen and an R side chain attached to the central carbon
Answer:
Column A Column B
1. CaS Calcium Sulfide
2. CaSO₄ Calcium sulfate
3. CaSO₃ Calcium sulfite
Explanation:
1) Calcium sulfide is a compound formed between calcium, Ca, and sulfur, S, with a chemical formula of CaS. It forms cubic crystals similar to rock salt, and smells like rotten eggs
2) Calcium sulfate is a chemical compound consisting of calcium, Ca, and sulfate SO₄. It is found in nature in the hydrated form as the mineral gypsum
3)Calcium sulfite is a chemical compound formed between calcium, Ca and sulfite, SO₃ used to treat water and preserve food.
