<h3>
Answer:</h3>
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
<h3>
Explanation:</h3>
We are required to complete the chemical equation given;
strontium carbonate + sulfuric acid → ??
- We know that, carbonates reacts with acids to form a salt, water and carbon dioxide.
- Strontium carbonate reacts with sulfuric acid to form strontium sulfate, water and carbon dioxide.
- Therefore, the equation for the reaction is;
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
- The equation is balanced as the number of atoms of each element are equal on both sides of the equation.
Answer:
The total enthalpy of the reaction has negative value which mean that the heat is lost during the chemical reaction into surroundings.
Explanation:
Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.
The total enthalpy of the reaction 
comes out to be negative.
Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.
The total enthalpy of the reaction comes out to be positive.
,ΔH= -1235.7 kJ/mol
The total enthalpy of the reaction has negative value which mean that the heat is lost during the chemical reaction into surroundings.
Answer:
oil and vinegar
the rest would mix well so you can't determine the individual components
Explanation:
Answer:
The minimum volume of the container is 0.0649 cubic meters, which is the same as 64.9 liters.
Explanation:
Assume that ethane behaves as an ideal gas under these conditions.
By the ideal gas law,
,
.
where
is the pressure of the gas,
is the volume of the gas,
is the number of moles of particles in this gas,
is the ideal gas constant, and
is the absolute temperature of the gas (in degrees Kelvins.)
The numerical value of will be 
if , , and are in SI units. Convert these values to SI units:
;- shall be in cubic meters,

Answer:
12.0 g/mL
Explanation:
From the question given above, the following data were obtained:
Mass of Rock = 360 g
Volume of water = 150 mL
Volume of water + Rock = 180 mL
Density of Rock =?
Next, we shall determine the volume of the rock. This can be obtained as follow:
Volume of water = 150 mL
Volume of water + Rock = 180 mL
Volume of Rock =?
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 180 – 150
Volume of Rock = 30 mL
Finally, we shall determine the density of the rock as illustrated below:
Mass of Rock = 360 g
Volume of Rock = 30 mL
Density of Rock =?
Density = mass /volume
Density of Rock = 360 / 30
Density of Rock = 12.0 g/mL
Thus, the density of the rock is 12.0 g/mL
