How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen? this is the formula for the reaction:?

1 answer:

5 0

Mg + O2(o is a diatomic element)⇒ Mg O(UNBALANCED)
Mg is +2, o is -2, so MgO is the product.
BALANCED EQUATION : 2Mg + O2 ⇒ 2MgO
There are 4 moles of magnesium, so there should be 4/2*2=4 moles of oxygen, and the product will have 4+4=8 moles.
there will be 8 moles of magnesium oxide.

The mass of a deuterium nucleus 21H is less than its components masses. Calculate the mass defect.________ amu

Inessa [10]

Answer:

The mass defect of a deuterium nucleus is 0.001848 amu.

Explanation:

The deuterium is:

$^{A}_{Z}X \rightarrow ^{2}_{1}H$

The mass defect can be calculated by using the following equation:

$\Delta m = [Zm_{p} + (A - Z)m_{n}] - m_{a}$

Where:

Z: is the number of protons = 1

A: is the mass number = 2

$m_{p}$ : is the proton's mass = 1.00728 amu

$m_{n}$ : is the neutron's mass = 1.00867 amu

$m_{a}$ : is the mass of deuterium = 2.01410178 amu

Then, the mass defect is:

$\Delta m = [1.00728 amu + (2- 1)1.00867 amu] - 2.01410178 amu = 0.001848 amu$

Therefore, the mass defect of a deuterium nucleus is 0.001848 amu.

I hope it helps you!
