Answer:
V₂ = 379.80 mL
Explanation:
According to <em>Charles' Law,</em> "<em>At constant pressure the volume of given amount of gas is directly proportional to the absolute temperature"</em>. Mathematically it is given as,
V₁ / T₁ = V₂ / T₂ ----- (1)
Data Given:
V₁ = 185 mL
T₁ = -125 °C = 148.15 K ∴ K = °C + 273.15
V₂ = ?
T₂ = 31.0 °C = 304.15 K
Solving eq. 1 for V₂,
V₂ = V₁ × T₂ / T₁
Putting values,
V₂ = 185 mL × 304.15 K / 148.15 K
V₂ = 379.80 mL
Hence, with increase in temperature the volume has also increased.
From the periodic table:
mass of Br = 79.9 grams
mass of Ar = 39.9 grams
Therefore,
molar mass of Ar = 39.9 grams
molar mass of Br2 = 2(79.9) = 159.8 grams
Now,
time for Ar / time for Br2 = sqrt(molar mass of Ar / molar mass of Br2)
time for Ar = 48 * sqrt(39.9 / 158.9)
time for Ar = 24.0528 minutes
Answer:
There are 1.8×1024 atoms in 1.5 mol HCl
Explanation:
Answer:
It depends on where it's located on the periodic table.
Explanation:
Metals are on left side of the periodic table except Hydrogen (H), which is a nonmetal, then there's the staircase, which has the metalloids, and on the right of the staircase are the nonmetals.
