Answer:
3grams
Explanation:
The reaction for the production of Magnesium dioxide will be
Mg + O2 → MgO
we have 5g of MgO (molar mass 40g)
no of moles of MgO = 5/40 = 0.125
Using unitary method we have
1 mole of Mg require 1 mole of MgO
0.125 Mole of MgO = 0.125mole of Mg
n = given mass /molar mass
0.125 = mass / molar mass
mass = 0.125* 24 = 3grams
The rates of the forward and reverse reaction depends on the temperature on which the reaction will proceed, either endothermic of exothermic. it also depends of the concentration of the reactants and products. if the reaction is exothermic, so if the reaction temperature is increased then it will favor the forward reaction, then if the reaction is lowered then it will favor the reverse reaction
Answer: amount of precipitation, average temperature
It can be done by you only
- First observe the figure or model .
- Then note the observations about its molecular structures .
- Then write it uses and why it is commercial most usable.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
An acid is defined as a substance which looses donates protons and thus forming conjugate base.
A base is defined as a substance which accepts protons and thus forming conjugate acid.
For example:
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms 
which is a conjugate base.
And, 
is gaining a proton, thus it is considered as a base and after gaining a proton, it forms 
which is a conjugate acid.
