The latter contains hydroxyl ions when dissolved in water making it basic.
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 .
Activation energy?? The energy needed to start a chemical reaction is called activation energy
The first one
A gas stove burner
Answer:
The answer is
<h2>1.33 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 3.46 g
density = 2.60 g/cm³
The volume is
We have the final answer as
<h3>1.33 cm³</h3>
