Answer:
False
Explanation:
chemically stable compounds are stable so they do not break down quickly.
Answer:
I think False
As
stable compounds are of lower energy and have a balanced charge. ... So, very loosely, a compound could be said to be stable when it is low in potential energy, has a neutral or spread out charge, and can be used in regular conditions.
THAT'S WHY THEY DO NOT BREAK DOWN EASILY
if wrong correct me pls
have a nice day

Have you ever heard someone try to speak or make noise underwater? Describe the experience.
IN YOUR OWN WORDS PLZ! :D
Answer:
A few years back I back in 8th grade I head somewhat of a scream underwater, at first I was amazed at the sound but I suddenly realized how physically possible, the only way to make noise under water is to breath in the water and that can drown you, as I heard this I almost immeaditetly bolted out of the water and saw someone either trying to destroy their lungs themselves or being uneducated, they ended up stopping after a bunch of people started staring at them.

What happens to wavelength as wave frequency increases?
Answer:
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Reason:- The Mechanism of Diffusion In the case of food coloring in water, the water is the solvent while the food coloring is the solute. Once they've mixed, they make a solution. Diffusion takes time, though how much time depends on the kinetic energy of the molecules randomly bouncing among each other.

Explain how adding crushed limestone reduces the acidity of the soil. Include a
general equation for the reaction.
Answer:
If a soil test indicates low magnesium, dolomitic limestone can be used to correct both the nutrient deficiency and pH. The value of limestone is in its ability to neutralize soil acidity. Limestone's properties differ considerably, and these differences influence the limestone's ability to neutralize soil acidity.

What kind of nuclear reaction occurs in the following reactions?
Answer:
No 1 is fission
while no 2 is fusion
Fission is splitting on nucleus while fusion is forming heavier nucleus with nuclei
The kind of nuclear reaction that occurs in the following reactions are:
i. nuclear fission
ii. nuclear fusion.
What is a nuclear reaction?Nuclear reactions are that reactions in which a nucleus or nuclei collides with subatomic particles to form another, different nucleus. There are two types of collisions. Nuclear fission and nuclear fusion.
Nuclear fission is a process when large nuclei split and create small, numerous nuclei. It happens due to the instability of an atom. It split into two daughter nuclei.
Nuclear fusion is a process in which two or more small nuclei combine to create a large, heavy nucleus. The process releases a large amount of energy or can be absorbed.
Thus, the processes are i. nuclear fission
ii. nuclear fusion.

A fluorinated organic gas in a cylinder is com-
pressed from an initial volume of 930 ml at
156 Pa to 400 mL at the same temperature.
What is the final pressure?
Answer in units of Pa.
Answer:
Final pressure = 362.7 Pa
Explanation:
Given that,
Initial volume, V₁ = 930 ml
Initial pressure P₁ = 156 Pa
Final volume, V₂ = 400 mL
We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.
[tex]V\propto \dfrac{1}{P}\\\\\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}\\\\P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{930\times 156}{400}\\\\P_2=362.7\ Pa[/tex]
So, the final pressure is equal to 362.7 Pa.
Given the unbalanced equation: Li + N2 -> Li3N When the equation is
correctly balanced using smallest whole numbers, the coefficient of the
Lithium is
A.1
B.2
C.3
D.6
Answer:
D) 6
Explanation:
The balanced equation would be:
6Li + N2 -> 2Li3N
To calculate the atoms of an element in a given molecule, we need to multiply stoichiometry by the number that is written on the foot of that element. Therefore, the correct option is option D.
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, displacement reaction.
The other characteristic of balanced reaction is that physical state should be written with each compound or molecule on reactant and product side. Physical state should be written in brackets. s means solid, l means liquid, g means gas.
The skeletal equation is
Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] Li[tex]_3[/tex]N
The number of atoms of nitrogen on reactant side is 2 while on product side it is 1 so to balance
Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] 2Li[tex]_3[/tex]N
The lithium atom on reactant side is 1 while on product side it is 6, so to balance
6Li + N[tex]_2[/tex] [tex]\rightarrow[/tex] 2Li[tex]_3[/tex]N
The coefficient of the Lithium is 6.
Therefore, the correct option is option D.

Hydrogen chloride gas reacts with water to produce an acidic solution. The equation for
the reaction is shown.
HCI + H2O → CI + H2O
Which statement describes what happens during the reaction?
A The chloride ion is formed by accepting an electron from the water.
B The hydrogen chloride loses an electron to form the chloride ion.
C The water accepts a proton from the hydrogen chloride.
D The water donates a proton to the hydrogen chloride.
neid.
Answer:
C The water accepts a proton from the hydrogen chloride.
Explanation:
The equation given in this question where hydrogen chloride reacts with water is as follows:
HCI + H2O → CI- + H3O+
From this equation, hydrogen chloride (HCl) loses or donates hydrogen ion (H+) or proton to water (H2O), which accepts it to become hydronium ion. Hence, in a nutshell, water (H2O) accepts a proton (H+) from the hydrogen chloride (HCl) in this reaction.

Magnesium hydroxide is an ingredient in some antacids. Antacids react with excess hydrochloric acid in the stomach to relieve
indigestion.
a) balance the reaction that occurs between Mg(OH)2 and HCI.
(select choice) Mg(OH)2 + (select choice) HCI = (select choice) MgCl2 + (blank) H2O
b) what are the mole ratios that would be used to determine the number of moles of MgCl2 produced when HCl reacts with Mg(OH)2.
(blank) mol MgCl2/ (blank) mol Mg(OH)2
(blank) mol MgCl2/ (blank) mol HCI
Answer:
a. 2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O
b. 1 mol MgCl2/ 1 mol Mg(OH)2
1 mol MgCl2/ 2 mol HCI
Explanation:
a. The reaction of an acid (HCl) with a base (Mg(OH)2) produce water (H2O) and the salt (MgCl2):
_HCl + _Mg(OH)2 → _MgCl2 + _H2O
To balance the Cl:
2HCl + _Mg(OH)2 → _MgCl2 + _H2O
To balance the oxygen:
2HCl + _Mg(OH)2 → _MgCl2 + 2H2O
The reaction is now balanced
2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O
b. Based on the balanced reaction, the moles ratios are:
1 mol MgCl2/ 1 mol Mg(OH)2
1 mol MgCl2/ 2 mol HCI
