B.
its the only one with ozone in the reaction O₃
Answer:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 104 kPa
= final pressure of gas = 52 kPa
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
Answer:
Explanation:
Density is the mass per unit volume of a substance. It is calculated by dividing the mass by the volume.
The mass of the mineral is 48.6 grams. The volume is 18 milliliters.
Substitute the values into the formula.
Divide.
The density of the mineral sample is <u>2.7 grams per milliliter.</u>
Let x be the oxidation state of S.
Therefore,
2x + 3(-2) = -2
2x = -2 + 6
2x = 4
x =2.
Hence oxidation state of S is +2.
Hope this helps!
