Answer:
Neon is an inner gas because it’s outer <u>__shell__</u> is full of electrons.
The new concentrations of
and
are 0.25M and 19M
Calculation of number of moles of each component,
Molarity of
= number of moles/volume in lit = 0. 500 M
Number of moles = molarity of
× volume in lit = 0. 500 M× 0.025 L
Number of moles of
= 0.0125 mole
Molarity of
= number of moles/volume in lit = 0. 38 M
Number of moles = molarity of
× volume in lit = 0. 38 M× 0.025 L
Number of moles of
= 0.95 mole
Calculation of new concentration at volume 50 ml ( 0.05L)
Molarity of
= number of moles/volume in lit = 0.0125 mole/0.05L
Molarity of
= 0.25M
Molarity of
= number of moles/volume in lit = 0.95mole/0.05L
Molarity of
= 19 M

Answer:
A
Explanation:
lies to the left of periodic table
The trajectory of their motion knocked the Earth into a different orbit.
The specific heat of the metal is 2.4733 J/g°C.
Given the following data:
- Initial temperature of water = 25.0°C
- Final temperature of water = 29.0°C
- Temperature of metal = 203.0°C
We know that the specific heat capacity of water is 4.184 J/g°C.
To find the specific heat of the metal (J/g°C):
Heat lost by metal = Heat gained by water.

Mathematically, heat capacity or quantity of heat is given by the formula;

<u>Where:</u>
- Q is the heat capacity or quantity of heat.
- m is the mass of an object.
- c represents the specific heat capacity.
- ∅ represents the change in temperature.
Substituting the values into the formula, we have:

Specific heat capacity of metal, c = 2.4733 J/g°C
Therefore, the specific heat of the metal is 2.4733 J/g°C.
