Answer:
<h2>The answer is 870 miles</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
<h3>distance = velocity × time </h3>
From the question
velocity = 290 miles/hour
time = 3 hours
The distance between the two cities is
distance = 290 × 3
We have the final answer as
<h3>870 miles</h3>

Answer:Binary acids are acids composed of two atoms ,a hydrogen element and non metal element .Binary acids are also known as Hydracids.
Explanation:For example
Hydrochloric acid (HCl), hydrofluoric acid (HF), and hydroiodic acid (HI) are all binary acids.
11.2L x 1mol/22.4L= 0.5 mol
Answer is: partial pressure of Xe is 22,95 atm.
m(He) = 10,5 g.
n(He) = m(He) ÷ M(He).
n(He) = 10,5 g ÷ 4 g/mol
n(He) = 2,625 mol.
m(Ne) = 10,5 g.
n(Ne) = m(Ne) ÷ M(Ne).
n(Ne) = 10,5 g ÷ 20,18 g/mol.
n(Ne) = 0,52 mol.
m(Xe) = 10,5 g.
n(Xe) = 10,5 g ÷ 131,3 g/mol.
n(Xe) = 0,08 mol.
Using <span>Dalton's law:
</span>p(Xe) = (0,08 mol / 0,08 mol + 0,52 mol + 2,625 mol) · 925 atm.
p(Xe) = 22,95 atm.
