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.
30 because it is the highest number of marriage

Answer:
Specific heat is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in temperature.
Explanation:
Answer:
c) CH3CH2CH2CH3
Explanation:
Surface tension; The molecules inside the liquid attract the surface molecules and try to draw the them and make the liquid to assume in the shape having the least surface area. The suface tension increase with increase in intermolecular forces of surface liquid.
CH3CH2CH2CH3 is non-polar and have weak intermolecular forces such as London-dispersion forces.
(CH3)2CO, H2O and CH3OH are polar and have strong intermolecular forces such as hydrogen bonding.
C6H6 have high molecular mass, so will have stronger intermolecular forces.
