Answer:

Q=80cal

Explanation:

Hello,

In this case, the relationship between heat, mass, specific heat and change in temperature is understood by:

Q=mCp(T_2-T_1)

In this case, since the involved substance is water, whose specific heat is 1 cal/(g°C), we compute the heat 4 mL of water need to rise the temperature from 10 °C to 30 °C as shown below:

Q=4mL*\frac{1g}{1mL}*1\frac{cal}{g\°C}*(30\°C-10\°C)\\  \\Q=80cal

Best regards.

According to valence bond theory, the minimum of the potential energy curve describing the interaction of H atoms in H2 correspo
tatuchka [14]

The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.

When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.
