Answer: Thus the volume of the balloon at this altitude is 419 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 751 mm Hg
= final pressure of gas = 495 mm Hg
= initial volume of gas = 340 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:


Thus the volume of the balloon at this altitude is 419 L
Answer:
D
Explanation:
P4 is polyatomic molecule
Transferring heat through electromagnetic waves
If you mean 4 moles per litre then:
In 1 litre there is 4 moles, therefore in .25 litres there is 1 mole.
1 mole of Magnesium Chloride would produce 2 moles of chloride ions (MgCl2 can also be written as Mg1Cl2, which dissolves to produce 1Mg(2+) and 2Cl(1-) ions: a 1:2 ratio)
So the answer is 2 moles of Chloride ions.
Answer:
Carbon forms the key component for all known life on Earth.
Explanation:
Complex molecules are made up of carbon bonded with other elements, especially oxygen and hydrogen and frequently also with nitrogen, phosphorus and sulfur. Carbon is abundant on Earth. It is also lightweight and relatively small in size, making it easier for enzymes to manipulate carbon molecules.
