Answer:
You get Ca(II)H^2
Explanation:
This is a reaction type equation calcium reacts with HA and forms a bond.
Since the molecular weight of water is about 18 g/mol, you have about 1 mol of water. So, now we know that it takes approximately 46.2 kJ of heat energy to warm 18.02g of water from 25C to 100C and then to vaporize it into steam. Hopefully this helped!
Explanation:
n = 5 --> n = 4
n = 4 --> n = 3
n = 3 --> n = 2
n = 2 --> n = 1
<span>So we can see that there are 4 different wavelength of
light that can be emitted</span>
Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Answer : The temperature of this gas will be, 206.9 K
Explanation :
The expression for the kinetic energy per molecule of monoatomic gas (argon) is:
...........(1)
The expression for the kinetic energy per molecule of diatomic gas (nitrogen gas) is:
.............(2)
The total kinetic energy of the molecule will be,
Now put all the expression in this, we get:
Now put all the given values in this expression, we get:
Therefore, the temperature of this gas will be, 206.9 K
