Answer : The new pressure acting on a 2.5 L balloon is, 8.6 atm.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 3.7 atm
= final pressure = ?
= initial volume = 5.8 L
= final volume = 2.5 L
Now put all the given values in the above equation, we get:
Thus, the new pressure acting on a 2.5 L balloon is, 8.6 atm.
Answer:
82.6 moles
Explanation:
chemical equation:
CO2+ 4H2 → CH4 + 2H2O
Given data:
moles of carbon dioxide = 82.6 mol
moles of methane = ?
through the balanced chemical equation we will compare the moles carbon dioxide with methane
CO2 : CH4
1 : 1
82.6 : 82.6
we are given hydrogen so 82.6 moles of carbon dioxide will produce 82.6 moles of methane.
An ionic compound is composed of anions and cations. A cation is a positively charged ion, and an anion is the opposite. A metal is composed of two or more cations. Since you need at least one cation and one anion for an ionic compound, the metal is not ionic.
