Answer:
1
Explanation:
there is only one sulphur (S) atoms in the formula for sodium sulphate
Answer:
0.51 cal/g.°C
Explanation:
Step 1: Given data
- Added energy in the form of heat (Q): 14 cal
- Mass of the liquid (m): 12 g
- Initial temperature: 10.4 °C
- Final temperature: 12.7 °C
Step 2: Calculate the temperature change
ΔT = 12.7 °C - 10.4 °C = 2.3 °C
Step 3: Calculate the specific heat of the liquid (c)
We will use the following expression.
c = Q / m × ΔT
c = 14 cal / 12 g × 2.3 °C = 0.51 cal/g.°C
Regard the principle of utilization of two gas.
Make a consistent control of hardware containing gas.
Make a consistent control of weight diminishing valves giving gas.
No smoking zone.
I think that your answer would be evaporation
This reaction is a special decomposition reaction called electrolysis.
The reaction looks like
H2O —> H2 + O2
These gaseous products exist in H2 and O2 form because they’re diatomic, which means they don’t exist in nature without being bonded to each-other.
We must then balance the reaction to get our final answer
2H2O + 2H2 + O2
