Answer:
They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity
Explanation:
No reaction occurs since all the ions appear on both sides of the equation, therefore, no product is formed.
<h3>What is a net ionic equation?</h3>
A net ionic equation is an equation in which the ions which appear on both sides of an ionic equation known as spectator ions are removed leaving only the products formed and the ions involved in their formation.
The equation of reaction is given below as follows:
The ions all appear on both sides of the equation, therefore, no product is formed.
Therefore, no reaction occurs.

Answer : K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
Explanation :
The relation between the equilibrium constant and standard Gibbs, free energy is:
where,
= standard Gibbs, free energy
R = gas constant
T = temperature
K = equilibrium constant
From the above relation we conclude that,
When K > 1 then the value of is negative.
When K < 1 then the value of is positive.
When K = 1 then the value of is zero.
When K = 0 then the value of is undefined.
Hence, K > 1is the true statement about the equilibrium constant for a reaction if for the reaction is negative.
The new concentration of sodium phosphate is 0.315 mol·L⁻¹.
We can use the dilution formula
:
<em>c</em>₁<em>V</em>₁ = <em>c</em>₂<em>V</em>₂
We can rearrange the formula to get
<em>c</em>₂= <em>c</em>₁ × (<em>V</em>₁/<em>V</em>₂)
∴ <em>c</em>₂ = 1.50 mol·L⁻¹ × (21.00 mL)/(100.0 mL)] = 1.50 mol·L⁻¹ × 0.2100
= 0.315 mol·L⁻¹
Answer:
Valency of Chlorine is 1 because it needs 1 electron to complete its octet (a shell of eight electrons). Valency is defined as "The combining power of an element" and Since, chlorine needs 1 electron to complete its valence shell, Its valency is 1.
