Answer: A.
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = 4.56 J
m = mass of substance = 123 g
c = specific heat capacity = ?
Change in temperature ,
Putting in the values, we get:
The specific heat of a 123 g substance that requires 4.56 J of heat in order to increase its temperature by 12.32 °C is
Answer: skeletal equation :
The products are sodium nitrate and barium sulphate.
balanced equation :
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The skeletal equation is:
The balanced chemical equation is:
