Answer:

For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.

Determine the oxidation numbers of all of the elements in the unbalanced reactions. Then, balance each redox reaction in basic s

Alisiya [41]

4. According to the explanation given in one previous session, in this case we have the following reaction:

Zn + NO3- -> Zn(OH)42- + NH3

Our important informations to have in mind always first:

Single elements = 0 of oxidation number

Zn = 0

Oxygen = 2-

NO3- = overall charge must be -1, and we have 3 oxygens, so a -6 charge, therefore N must give a charge of +5

N (reactant) = 5+

Zn(OH)42- = overall charge -2, the charge for OH is always -1, we have 4 OH, therefore -4 of charge, to give -2 of overall, Zn must have a charge of +2

Zn (product) = 2+

OH = 1-

NH3 = 0

Now for the balancing of the reaction:

4 Zn + NO3- + 7 OH- + 6 H2O -> NH3 + 4 Zn(OH)42-

How could you use two beakers distilled water two hot plates two thermometers and salt to test if adding salt affects the boilin

ICE Princess25 [194]

You are given two beakers, distilled water, two hot plates, two thermometers and salt. These materials are enough in order to test the effect of salt in the boiling point water. To do this, you set up two beakers. In one of the beakers, you add pure distilled water and nothing else. For the other beaker, you put a solution of salt and water. You place these beakers on separate hot plates and place inside the beakers the thermometers. You heat these substances until they boil and then you measure the boiling points of the substances. You would observe that the boiling point of the solution would have a higher boiling point than the pure liquid.
