Answer:
A chemical equation can be described as a symbolic representation of a chemical reaction. It can be written in the form of words or symbols.
The following chemical reaction can be completed as :
Na2SO4·10H2O + 2C = Na2S + 10H2O + 2CO2
Sodium Sulfate Decahydrate + Diamond = Sodium Sulfide + Water + Carbon Dioxide
The products of the reaction are:
- Sodium Sulfide (Na2S)
- Water (H2O)
Answer:
2.103 J/C
Explanation:
Quantity of heat = Heat Capacity * Temperature change
Heat Capacity = Quantity of heat / Temperature Change
Heat Capacity = 61/29
Heat Capacity = 2.103 J/C
Answer:
B
Explanation:
Compounds are made up of 2 or more different atoms that bond to form a compound.
You did not include the statements but since magnesium chloride is ionic substance that we know that magnesium and chlorine formed an ionic bond. Therefore your statement most likely will talk about how one magnesium atom gave up 2 electrons while two chlorine atoms took 1 electron. The reaction looks like Mg+2Cl⇒MgCl₂.
I hope this helps. Let me know in the comments if anything is unclear.
Answer:

Explanation:
C = Allowable concentration = 1.1 mg/L
= Flow rate of river = 
= Discharge from plant = 
= Background concentration = 0.69 mg/L
= Maximum concentration that of the pollutant
The concentration of the mixture will be

The maximum concentration that of the pollutant (in mg/L) that can be safely discharged from the wastewater treatment plant is
.
