therefore the ozone layer is preserved.
have a nice day.
Please Help I need to finish this by the end of the day!
Answer:
C
Explanation:
If I am not mistaken, due to the conservation of mass, whatever mass is on the side of the reactants should be the same for the product side.
This means
218.76g+53.96g = 272.72g
272.72g-266.66g = 6.06g
So the answer should be C

10) How much 0.075 M NaCl solution can be made by diluting 450 mL of 9.0 M NaCl?
Answer:
54L
Explanation:
Consider this reaction: NH4+ + HPO42− → NH3 + H2PO4−
Which is the conjugate base?
NH4+
NH3
HPO42–
H2PO4–
The conjugate base is formed when an acid loses its hydrogen or proton. In the reaction between ammonium ion and hydrogen phosphate, HPO₄²⁻ is the conjugate base. Thus, option C is correct.
What is a conjugate base?Conjugate bases are formed when the substance accepts or absorbs the proton or the hydrogen ion from the acids in the solution. It can be said as a base with an added hydrogen ion to it.
The chemical reaction of the acids and the bases has been shown as,
NH₄⁺ + HPO₄²⁻ → NH₃⁺ + H₂PO₄⁻
From the reaction, it can be said that ammonia donated its proton, whereas HPO₄²⁻ accepted hydrogen ions from the acid.
Therefore, HPO₄²⁻ has been the conjugate base in the given chemical reaction.

if a car collides with a barrier and hit with a hundred 50 Newtons of force how much force does the barrier put in the car?
Answer: 50 Newtons
Explanation:
Due to newtons third law of motion for every action there is an equal and opposite reaction or in this case the equal and opposite amount of force applied so the same 50 N is applied on the car by the barrier

How much heat is required for 25.0g of water to rise in temperature from 35.0 to 75.0°C?
Formulas~
*q = mcT (temp change)
*q = mH (phase change)
Answer:
4180J
Explanation:
(25.0g)(4.184J/g°C)(75°C-35.0°C)
(25.0g)(40.0°C)(4.184J/g°C)
(1.00*10³g°C)(4.184J/g°C) = 4184J

A. industrial effluent
B. Agricultural runoff
C. illegal dumping of waste
D. Oil leaking from your car
Answer:
Option C.
Ilegal dumping of waste
Explanation:
This is because non point source of pollution refers to source of pollution that are many and not directly one which is illegal or does not meet the legal term. This type of pollution does not have a point source, it has many sources and this type of pollution is cause by rainfall or precipitation. Where when the rain fall, it wash away the waste through to water bodies, causing pollution and endangering water bodies.

How many grams of Ag2S
are produced from 10.0
grams of AgI?
10
AgI + Nazs
Ag2S +NaI
Answer:
10.0 g of AgI will produce 5.28 g of Ag₂S
Explanation:
The balanced equation of the reaction is given below:
2AgI + Na₂S ----> Ag₂S + 2NaI
From the equation of reaction, 2 moles of AgI produces 1 mole of Ag₂S
The moles of a substance is related to its mass by a quantity known as molar mass which is defined as the mass of one mole of that substance.
Molar mass of AgI = (108 + 127) g = 235 g
Molar mass of Ag₂S = (108 × 2 + 32) g= 248 g
Mass of 2 moles of AgI = 2 × 235 g = 470 g
470 g of AgI produces 248 g of Ag₂S
10 g of AgI will produce 248 /470 × 10 g of Ag₂S = 5.28 g
Therefore, mass of Ag₂S produced = 5.28 g
