A is the correct answer from what i understand in this question
I got you
The molecular formula for the combustion of butane in oxygen is:
2 C4H10 + 13 O2 ---> 8 CO2 + 10 H20
<span>You take the mass of carbon dioxide, 56.8g, divide by its molar mass, 44.01g/mol, to produce the moles of carbon dioxide. This is multiplied by the molar ratio of butane/CO2, (2/8) = 1/4, which gives the moles of butane required to produce the carbon dioxide. Multiply the number of moles of butane by its molar mass, 58.12g/mol, to produce the mass of butane. Mass of butane = 18.8g</span>

The weak base carbonate reacts with the water forming bicarbonate and the hydroxide ion.
<h3>What is a weak base?</h3>
The weak bases are given as the compounds that have the inability to get completely dissociated in water.
The carbonate is given as the weak base, as in water it remains constituted in the form of a bond with oxygen.
The reaction of water with the carbonate ion is given as:

Oxygen gains two electrons when it bonds to form a complete outer shell and magnesium loses two electrons when bonding to gain its full outer shell.
As electrons are negative, the oxygen (which gains electrons) will become negative and the magnesium (which loses electrons) will become positive.
The negative and positive ions will then attract to one another due to the magnetic pull of the positive and negative.
