Answer:
A standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
All the data is given in the question and these are as follows:-
Moles - 0.75
Na - 6.022*10^{23
The formula we are using to find the molecules is as follows:-
n = \frac{molecule}{Na}n=
Na
molecule
After, putting the value and solving it. we will get
0.75 * 6.022*10^2^3 = 4.5165*10^{23
Answer:
B. Negative ion with a radius larger than the radius of the atom
Explanation:
When a negative ion is formed, electrons are added to the atom. As electrons are added to the atom, the size of the electron cloud increases accordingly.
As a result of this, a negative ion is always larger than its corresponding atom. Hence, nitrogen ion must be larger than the nitrogen atom based on the facts stated above.
Answer: the name of the reaction is Combustion
Explanation: Combustion is a reaction in which a substance burns in air (oxygen) to produce CO2 and H20
2/1.01=1.980=2
32.7/32.07=1.020=1
65.3/16.00=3.969=4
H2SO4. oxygen is 1
