Answer:</h3>
5.6 L
<h3>
Explanation:</h3>
We are given;
- Initial volume, V1 = 3.5 L
- Initial pressure, P1 = 0.8 atm
- Final pressure, P2 = 0.5 atm
We are required to calculate the final volume;
- According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
- That is; P α 1/V
- Mathematically, P=k/V
- At two different pressure and volume;
P1V1 = P2V2
In this case;
Rearranging the formula;
V2 = P1V1 ÷ P2
= (0.8 atm × 3.5 L) ÷ 0.5 atm
= 5.6 L
Therefore, the resulting volume is 5.6 L
Answer:
it will float if the object is 1g/cm^3(water 's density ) because it is less dense
The compound which is ionic is Kh
Kh is ionic because ionic compound is made between a metal and a non metal. K( potassium) is a metal while H (hydrogen) is a non metal. The bond between potassium and hydrogen form ionic bond whereby potassium loses one electron and hydrogen gain one electron to form an ionic compound.
Answer:
Oxygen is solvent and Helium is solute.
Explanation:
Helium is a complety inert gas which do not react with other compounds whereas, oxygen can take part in chemical reaction with many compounds.
- if we mix 15 mL of oxygen and 5mL of helium then the oxygen is the solvent and helium is solute.
- In a mixture the compound with the greater volume is solvent and the compound with lwss volume is solute.
- in this case, oxygen has greater volume than that of helium so oxygen is solute and helium is solvent here.
