Given that,
Volume, d = 2 mL
Mass, m = 18 grams
We have to find the density. Density of an object is equal to mass per unit volume. It can be given by:
So, the density is 9 g/cm³.
Answer:
C, increases/decreases
Explanation:
As you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus.
Answer: Volume of the balloon at this altitude is 46.9 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 = 737 mm Hg
= final pressure of gas = 385 mm Hg
= initial volume of gas = 28.6 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 46.9 L
4.5 × 10⁻⁵ L of NH₃ are needed per liter of flue gas at 1.00 atm.
<h3>What is Balanced Chemical Equation ?</h3>
The equation during which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation is called balanced chemical equation.
The given balanced chemical equation is
4NH₃(g) + 4NO(g) + O₂(g) → 4N₂(g) + 6H₂O(g)
<h3>How to find mole fraction ?</h3>
To find mole fraction use this expression
P.P = M.F × T.P
where,
P.P = Partial Pressure
M.F = Mole Fraction
T.P = Total pressure
Here,
Given flue gas total pressure (T.P) is 1.00 atm
Given NO Partial Pressure (P.P) = 4.5 × 10⁻⁵
Now putting the values we get
P.P = M.F × T.P
4.5 × 10⁻⁵ atm = 1.00 atm × M.F
M.F = 4.5 × 10⁻⁵ L
Thus from the above conclusion we can say that 4.5 × 10⁻⁵ L of NH₃ are needed per liter of flue gas at 1.00 atm.
