Answer:
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K3C6H5O7.
Chemical formula: K3C6H5O7
Density: 1.98 g/cm3
Melting point: 180 °C (356 °F; 453 K)
Boiling point: 230 °C (446 °F; 503 K)
Explanation:
Answer:
Mass of water = 41.8 g
Explanation:
Given data:
Mass of water = ?
Change in temperature = 3.0 °C
Specific heat capacity = 4.184 j/g.°C
Heat absorbed = 525 j
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 3.0°C
Now we will put the values in formula.
525 J = m × 4.184 j/g.°C × 3.0°C
525 J = m × 12.552 j/g
m = 525 J/ 12.552 j/g
m = 41.8 g

</span>For all chemical

There are two types of reaction: endothermic

and exothermic reaction (chemical reaction that releases more energy than
it absorbs).
