A study is conducted to examine the effect of NaCl concentration on enzyme activity with the following results. Activity was tes

Marina86 [1]

Answer:

The answer is "Option D".

Explanation:

The behavior of 0.1M NaCl also isn't substantially larger objectively than those of 0.05M NaCl because a p-value above 0.05 (p>0.05) indicates no ability to tell differential and is a strong proof in favor of a null hypothesis.

The other wrong choices can be defined as follows:

Option A as it's just the reverse of the correct answer to the null.
Options B and C because p worth tests to support nor oppose the null hypothesis.

2Fe + 3Cl2 → 2FeCl3 which of the following options gives the correct reactant ratio?

Mademuasel [1]

<u>Answer:</u> The reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$

<u>Explanation:</u>

Mole ratio is defined as the ratio of the amount of moles of two substances that are participating in a chemical reaction.

In the given chemical equation:

$2Fe+3Cl_2\rightarrow 2FeCl_3$

The reactants are Fe and $Cl_2$ and the product is $FeCl_3$

The mole ratio is basically the stoichiometric ratio of the chemical compounds taking part in a chemical reaction.

The mole ratio of reactants is stoichiometric ratio of Fe and $Cl_2$ , which is:

$Fe:Cl_2=2:3$

Hence, the reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$
