The specific heat capacities of two substances are given in the table below. Substance
Specific heat capacity /JgK
Ethanol
2.43
Water
4.18
Which statement is correct?
If equal masses of water at 20 c and ehtanol at 50 c are mixed, the final temperature is 35 C
If the same heat is supplied to equal masses of ethanol and water, the temperature of water increases more,
More heat is needed to increase the temperature of 50g water by 50 C than 50 g of ethanol by 50 C.
If equal massres of water and ethanol at 50 C cool down to room temperature, ethanol liberates more heat.

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
