The balanced molecular equation is Na₂S(aq) + ZnSO₄(aq) → Na₂SO₄(aq) + ZnS(s)
The total ionic equation is 2Na⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + SO₄²⁻(aq) → 2Na⁺(aq) + SO₄²⁻(aq) + ZnS(s)
The net ionic equation is S²⁻(aq) + Zn²⁺(aq) → ZnS(s)

what is precipitation?</h3>
Any liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. Snow, sleet, and rain are just a few of the variations. One of the three main processes that make up the global water cycle is precipitation, along with evaporation and condensation.
Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. Droplets fall to the Earth when they are sufficiently heavy. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations. Depending on the temperature within the cloud and at the Earth's surface, these ice crystals eventually discharge to the Earth as snow, hail, or rain.

Answer:
The number of hamburgers is 109.
Explanation:
Let h = number of hamburgers
Let c = number of cheeseburgers
The total number sold gives us the equation below.
h + c = 327
"The number of cheeseburgers sold was two times the number of hamburgers sold.
This gives us the equation
c = 2h
Now we substitute c with 2h in the first equation and solve for h.
h + 2h = 327
3h = 327
h = 109
The number of hamburgers is 109.
Answer:
C. a mountain peak
Explanation:
Boiling occurs when vapor pressure equals atmospheric pressure.
The vapor pressure is the pressure exerted by the gas leaving the pot and those returning back. For boiling to occur, the vapor pressure must exceed the atmospheric pressure around.
At sea level, the atmospheric pressure is very high. With altitude, the air becomes thinner and atmospheric pressure becomes lower.
With increasing altitude, the low atmospheric pressure makes the boiling point lower as a result of the decreasing pressure on the vapor.
The boiling point can then easily be reached at higher altitudes.
<u>Answer:</u> The coefficient of silver chloride in the chemical reaction is 2
<u>Explanation:</u>
Decomposition reaction is defined as the reaction in which a single large substance breaks down into two or more smaller substances.
The general equation for the decomposition reaction follows:
When silver chloride decomposes when exposed to sunlight, it produces silver metal and chlorine gas
The chemical equation for the decomposition of silver chloride follows:
By Stoichiometry of the reaction:
2 moles of solid silver chloride decomposes to produce 2 moles of silver metal and 1 mole of chlorine gas
Hence, the coefficient of silver chloride in the chemical reaction is 2
