Answer:
This is False
Explanation:
A chemical change is when the matter is completely changed.
When you have water and boil it to be a gas, it is still the same matter, just in a different form.
I hope this helps :)
I know it is far late but the atom number remains the same
Answer: 20
Explanation: there you go my freind
Answer:
Explanation:
Let A₀ = the original amount of ⁵⁵Co
.
The amount remaining after one half-life is ½A₀.
After two half-lives, the amount remaining is ½ ×½A₀ = (½)²A₀.
After three half-lives, the amount remaining is ½ ×(½)²A₀ = (½)³A₀.
The general formula for the amount remaining is:
A =A₀(½)ⁿ
where n is the number of half-lives
n = t/t_½
Data:
A = 1.90 ng
t = 45 h
t_½ = 18.0 h
Calculation:
(a) Calculate n
n = 45/18.0 = 2.5
(b) Calculate A
1.90 = A₀ × (½)^2.5
1.90 = A₀ × 0.178
A₀ = 1.90/0.178 = 10.7 ng
The original mass of ⁵⁵Co was .
Oxidation of a 24-carbon fatty acid would require ELEVEN (11) rounds of beta-oxidation and TWELVE (12) rounds of the Krebs cycle. It is part of cellular respiration.
<h3>The Krebs cycle and cellular respiration</h3>
Cellular respiration is a group of chemical reactions by which aerobic cells can produce ATP by using energy from foods.
Cellular respiration has three parts: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During the Krebs cycle, hydrogen atoms or electrons pass through a series of hydrogen/electron carriers.
