Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant

Answer:
(102 900 ÷ 12) + (170 × 1.27) = 8800
Step 1. Evaluate the expressions inside the parentheses (PEMDAS)
102 900 ÷ 12 = 8575
170 × 1.27 = 215.9
In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.
Thus, the underlined digits are not significant, but we keep them in our calculator to avoid roundoff error.
Step 2. Do the addition (PEMDAS).
8575
+ 215.9
= 8790.9
Everything that you add to an insignificant digit gives an insignificant digit as an answer.
Thus, the underlined digits are not significant.
We must drop them and round up the answer to 8800.

If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (show work)
Answers
Answer:
8.
Explanation:
Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.
If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.
16 - 8 = 8

Answer:
²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He
Explanation:
In alpha decay;
The mass number decreases by 4
Atomic Number decreases by 2
Mass Number = 243 - 4 = 239
Atomic Number = 95 - 2 =93
Element = Neptunium (Np)
Equation for the decay is given as;
²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He

In a chemical reaction, the atoms of the reactants unbond, rearrange, and then rebond to form the products. Therefore, option A is correct.
What is chemical reaction ?Chemical reaction, the transformation of one or more chemicals the reactants into one or more distinct compounds, the products. Chemical elements or chemical compounds make up substances.
Combustion reaction, decomposition reaction, neutralization reaction, redox reaction, precipitation or double-displacement reaction, and synthesis reaction are some of the numerous types of reactions.
In a chemical reaction, bonds between molecules of the reactant are broken and new bonds between molecules of the product are established to create a new substance.
A chemical equation is nothing more than a mathematical statement that represents how reactants form products.
Thus, option A is correct.
