Answer:
The problem provides you with the solubility of potassium chloride, KCl , in water at 20∘C , which is said to be equal to 34 g / 100 g H2O . This means that at 20∘C , a saturated solution of potassium chloride will contain 34 g of dissolved salt for every 100 g of water.

Answer: 46.875%
the moles of C2H6 is 32/(12.2+6) = 16/15 (mol)
the moles of CO2 is 44/(12 + 16.2) = 1 (mol)
have:
2C2H6 + 7O2 ⇒ 4CO2 + 6H2O
0,5 <= 1
=> C2H6 reacts 0.5 mol
=> H = %

Answer:
fission
fusion
Explanation:
The two reactions shown are nuclear reactions. There are two main types of nuclear reactions;
1) fission reaction
2) fusion reaction
A fission reaction is said to have occurred when a large and unstable nuclide is bombarded with neutrons thereby causing it to decay into daughter nuclei.
A fusion reaction involves the combination of two light nuclei to yield a heavier nuclei.
In the first reaction, a neutron was used in bombarding a uranium nucleus to yield the products listed on the product side of the nuclear equation. We know this by comparing the sum of the masses and charges on the product side with those on the reactant side in order to decide what the bombarding particle is.
The second reaction involves the fusion of two deuterium nuclei to yield one helium nuclei and neutrons as shown.
Explanation:
When work is done then there will occur change in volume. And, most change in volume occurs when there will be production of gas is taking place. We assume that no work is done when no gas is produced.
(a) For
Here, 3 moles of gas is producing 0 moles of gas. This means that work is done on the system.
(b) And, more is the production of a gas taking place in a reaction more will be the amount of work done by the system.
For
Here, 2 moles of a gas is producing 3 moles of a gas. Since, gas is increasing so, work will be done by the system.
Answer:
The same as on earth
Explanation:
mass is the amount of matter in an object and the mass of an object is always the same at any point in time
gravity will only have effect on the weight and not the mass.
so assuming the question was talking about the weight, then we can say the weight will be lesser on Mercury
