a-k please

1. Mark the following statements from (a) - (o) True or False. 45 points (3 points each) The two isotopes of chlorine, 35CI and 37Cl will have 18 and 20 protons respectively. As suming a constant temperature, the volume of a gas will decrease with an increase in pressure. Unlike X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS) cannot be used for nondestructive trace analysis. NaF has larger lattice energy than KCl. boiling point of ammonia (NH3) is lower than that of methane (CHA). Silicon doped with aluminum will be a p-type semiconductor. The sign ofAS for the system 2Al(s) + 3C12(g)-2AICI3(s) is positive (+). The enthalpy is a state function whose value depends only on the state (h) of the system. (i) The change in the internal energy (AE) equals the heat flow under constant pressure. An exothermic process, with a decrease in entropy will be spontaneous only at lower temperatures. Os is the thermodynamically more stable of the two isotopes of oxygen. Water acts as an acid in the reaction, HOLD NH4+(aq) + OH(aq)

Explanation / Answer

a.

false, since proton is the same for an element

b.

true, due to PV = k ratio

c.

True, it will destroy it

d.

true, NaF > KCl, since K ad Cl are larger than Na, F

e.

false, since NH3 has H.bondings, requires more energy

f.

true

g.

false, gas is chaotic, so it decreases

h.

true, it is state funciton

i.

false, only at constant volume

j.

true, T must be low

k

false, O2 is much more stable
