The specific heat capacity of water (which is defined as the amount of heat required to raise the temperature of one gram of water by 1 degree kelvin) is given as <span>4.1813J/gK (at 25°C).
Therefore, to get the heat capacity of a certain mass (in grams), we just have to multiply this mass by the specific heat capacity of water as follows:
heat capacity of 170 g = 170 * </span><span>4.1813 = 710.821 J/K</span>
Answer:
Number of produced moles of carbondioxide is 0.113 mol.
Explanation:
Excess of sulphuric acid is present.And the sodium carbonate is completely consumed.
Molar mass of sodium carbonate = 105.99g/mol
Given mass of sodium carbonate =12 g/mol
one mole of sodium carbonate produce one mole of carbondioxide.
0.113 mole of sodium carbonate produce 0.113 mole of carbondioxide.
Therefore, 0.113 mol of carbondioxide produced in flask 7.
Answer:
radiant energy, solar energy
During nuclear fusion, radiant energy and solar energy from the core of the Sun is released. Hope it helps!
When placed in an electrical field, the negative charge found in the sugar-phosphate backbone of DNA polymers cause them to migrate towards the positive electrode.
<span>In gel electrophoresis, electricity is used to separate fragments of DNA based on its length. DNA is place in a porous gel. The pores of the gel restricts the movement of the DNA. It then creates fragments on the DNA because its movement varies on its lengths. </span>
