Answer:
9 times
Explanation:
A + 2B → products
rate = k[A][B]2
While holding the concentration of A constant, the concentration of B is tripled. Predict by what factor the rate of reaction increases.
We can achieve this by given the concentration dummy values.
Assuming the following values (Any number works, or letters);
concentration of A = 1
Concentration of B = 2
rate = k[A][B]2
rate = k (1)* (2)^2
rate = k 4 ....... i
When Conc of B is tripled;
Concentration of B = 3 * 2 = 6
rate = k[A][B]2
rate = k (1) * (6)^2
rate = k 36 .... ii
Comparing both rates;
The ratio is 36: 4, upon simplifying = 9 : 1
This means the factor increases by 9 times
Density of a substance is given by dividing its mass with volume.
The volume of the block is 3.5 cm× 2.0 cm ×1.5 cm = 10.5 cm³
thus density = 34.56 g/ 10.5 cm³
= 3.291 g/cm³
Answer:
10 C-8/5 - 16 e- → 10 C0 (oxidation)
16 Cl0 + 16 e- → 16 Cl-I (reduction)
Explanation:
The answer should be the first one, cells are made of living things. Which is false, because living things do not make up cells, cells make up living things.
