Answer: 2.54g
Explanation:
Molar Mass of H2O2 = (2x1) + (2x16) = 34g/mol
1mole (34g) of H2O2 contains 6.02x10^23 molecules
Therefore Xg of H2O2 will contain 4.5x10^22 molecules i.e
Xg of H2O2 = (34x4.5x10^22)/6.02x10^23 = 2.54g
Answer: The pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
Explanation:
Given: Pressure = 12.2 psi
According to the standard conversion of units, 14.7 psi = 1 atm = 760mmHg.
Therefore, 1 psi equal to how many mm Hg is calculated as follows.
Hence, 12.2 psi will be converted into mm Hg as follows.
Thus, we can conclude that the pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
546hm = 54600m
643hg=64,300,000mg
2km=78740.2in
18lb=8.16466kg
When thermal energy is added, the motion of particles increases.
This can be thought of when thinking of a gas. We know that a gas includes particles that move fast and are spaced far apart from each other. On the opposite side of the spectrum, we know that a solid includes particles that are closely packed together with limited movement.
Using those examples, we know that a solid usually occurs at colder temperatures (with low thermal energy), and gases occur at warmer temperatures (with high thermal energy).
Therefore, when thermal energy is added, particle motion increases.
The equation of line q is determined as y = ¹/₈x - ⁹/₄.
<h3>What is slope?</h3>
The slope of a line is the change in y axis to change in x axis.
<h3>Slope of line P</h3>
y = – 8x + 6
from general line equation, y = mx + c
where;
m = - 8
<h3>Slope of line q</h3>
m₂ = -1/m
m₂ = -1/-8
m₂ = 1/8
<h3>Equation of line q</h3>
(y - y₁) / (x - x₁) = m₂
(y + 2)/(x - 2) = 1/8
y + 2 = ¹/₈(x - 2)
y + 2 = ¹/₈x - ¹/₄
y = ¹/₈x - ⁹/₄
Thus, the equation of line q is determined as y = ¹/₈x - ⁹/₄.
