The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.
<h3>
What is solubity ?</h3>
It is the ability of a solute to be dissolved, especially in water.
As the temperature increases the solubility of the gas generally decreases"
According to given information and graph attached as reference ;
- Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
- Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
- Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9
grams. - Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.
- Solubility of Ce₂(SO₄)₃·9H₂O (ceasium sulfate nonahydrate) at 40°C is 6.2 grams.

Answer:
Petroleum
Hydrocarbon gas liquids
Natural gas
Coal
Nuclear energy
Explanation:
These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels.
Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal.
Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. Scientists think uranium was created billions of years ago when stars formed. Uranium is found throughout the earth’s crust, but most of it is too difficult or too expensive to mine and process into fuel for nuclear power plants.
From 30 April 1789 to 4 March 1797
Answer:
According to the scientists, evidence of an underground ocean suggests that Enceladus is one of the most likely places in the solar system to "host microbial life". Emissions of water vapor have been detected from several regions of the dwarf planet Ceres.
Explanation:
Volume = 0.50 L
Molar mass KBr = 119.002 g/mol
Molarity = 0.125 M
Mass ( KBr) = ?
mass = molarity * molar mass * volume
mass = 0.125 * 119.002 * 0.50
mass = 7.437625 g of KBr
hope this helps!
