Answer:

T=4985.5^{\circ}K

Explanation:

The equation that relates heat Q with the temperature change T-T_0 of a substance of mass <em>m </em>and specific heat <em>c </em>is Q=mc(T-T_0).

We want to calculate the final temperature <em>T, </em>so we have:

T=\frac{Q}{mc}+T_0

Which for our values means (in this case we do not need to convert the mass to Kg since <em>c</em> is given in g also and they cancel out, but we add 273^{\circ} to our temperature in ^{\circ}C to have it in ^{\circ}K as it must be):

T=\frac{Q}{mc}+T_0=\frac{40.5J}{(15g)(0.128J/g^{\circ}C)}+(298^{\circ}K)=4985.5^{\circ}K

Enter the chemical formula of a binary molecular compound of hydrogen and a group 7a element that can reasonably be expected to
LenKa [72]

The chemical formula of a binary molecular compound of hydrogen and a group 7a element that can reasonably be expected to be less acidic in aqueous solution than HBr is HF

Group 7a that forms binary molecular compounds of Hydrogen are  Halogens such as Iodine I, Bromine Br, Chlorine Cl and Fluorine F. Out of these four HF is the least acidic. This is calculated based on Acid dissociation constant. HF has the least value out of these four, so it is the least acidic.

A  binary molecular compound is a compound that consists of two non metals elements only.

Therefore, the chemical formula of a binary molecular compound of hydrogen and a group 7a element that can reasonably be expected to be less acidic in aqueous solution than HBr is HF.
