Nuclear energy released in nuclear fission and fusion is much larger than chemical reactions because of the astonishing amounts of energy being released at one moment.
Answer:
Explanation:
Using Gay lussac's law equation as follows;
P1/T1 = P2/T2
Answer:
a) the element belongs to group 2
b) see image attached
c) Magnesium
d) X3N2
Explanation:
Any ion with the formula X^2+ was derived from group 2 elements. The group two element found in period 3 is magnesium alone.
Since the nitride ion has a valency of -3 and X^2+ has a valency of +2 , then a compound formed between X^2+ and the nitride ion will have the formula X3N2.
Answer:
reduces
Explanation:
According to Boyle's law, when the pressure of a gas increases at constant temperature the volume reduces.
Boyle's law states that "the volume of fixed mass of a gas is inversely proportional to the change in pressure if the temperature is constant".
- It suggests that at constant temperature, if pressure increases, temperature reduces.
Mathematically, it is expressed as;
P1 V1 = P2 V2
P and V are pressures
1 and 2 are initial and finals state.
Answer:
If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
