Answer:The ones "most" similar would be the ones closest in mass as well. Those would be Lithium (Li) and Potassium (K)
Explanation:
19 protons and 19 electrons but neutrons are vary
The answer is B- 124 degrees
Answer:
<h2>Density = 8.96 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of copper = 89.6 g
volume = 10 cm³
Substitute the values into the above formula and solve
That's

We have the final answer as
<h3>Density = 8.96 g/cm³</h3>

Equilibrium will shift towards the products when temperature is decreased in an exothermic reaction of the formation of ammonia.
<h3>What is an exothermic reaction?</h3>
An exothermic reaction is a reaction in which heat content of the reactants is greater than the heat content of product.
In an exothermic reaction, heat is given off.
For an exothermic reaction in equilibrium, increasing temperature shifts equilibrium to the towards the left, towards the reactants.
On the other, equilibrium will shift towards the products when temperature is decreased.
Therefore, equilibrium will shift towards the products when temperature is decreased in the reaction of the formation of ammonia.
