Julli [10]3 years ago
5 0

Answer:

<h2>1. high</h2><h2>2. low</h2>

Explanation:

Iodine is an important and essential element or nutrient of the diet that has many important roles in the body of human beings and some other organisms. When the deficiency of the iodine takes place in the diet or overall in the body then such type of the deficiency is called dietary iodine deficiency that leads to the high level of the TSH of the plasma and thus the thyroxine level decreases or becomes low. Iodine deficiency causes goiter and some other metabolic processes in the body.

Aluminum chloride, AlCl3, is an inexpensive reagent used in many industrial processes. It is made by treating scrap aluminum wit
mylen [45]

Answer:

83.8%

Explanation:

The balanced reaction equation is;

2Al(s) + 3Cl2(g) → 2AlCl3(s)

Now we have to obtain the limiting reactant as the reactant that produces the least amount of AlCl3

Amount of Al = 3.11g/27 g/mol = 0.115 moles

If 2 moles of Al yields 2 moles of  AlCl3

Then 0.115 moles of Al yields 0.115 moles of  AlCl3

For Cl2

Amount of Cl2 = 5.32 g/71 g/mol= 0.075 moles

If 3 moles of Cl2 yields 2 moles of  AlCl3

0.075 moles of Cl2 yields 0.075   * 2/3 = 0.05 moles of  AlCl3

Hence Cl2 is the limiting reactant

Theoretical yield of  AlCl3 = 0.05 moles of  AlCl3 * 133g/mol = 6.65 g

%yield = actual yield /theoretical yield * 100

%yield = 5.57 g/6.65 g * 100

%yield = 83.8%

Why Formaldehyde is more reactive than Acetaldehyde?
tatyana61 [14]
Aldehydes are usually more reactive<span> toward nucleophilic substitutions </span>than<span> ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.</span>

Effectus [21]

Answer:

The number of atoms in the outermost shell  

Explanation:

For example, the electron shells in the alkali metals contain the following numbers of electrons:

 Li: 2, 1

Na: 2, 8, 1

 K: 2, 8, 8, 1

They all have one electron in their outermost shell, and they have similar chemical properties.

marta [7]

Answer:

<h2>80 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 20 × 4

We have the final answer as

<h3>80 N</h3>

Hope this helps you
