Answer:
Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. The boiling point of methane is −162 °C (−259.6 °F) and the melting point is −182.5 °C (−296.5 °F).
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
Answer: B. you will need 53.2 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
The balanced reaction is:
2 moles of aluminium react with= 3 moles of chlorine
Thus 0.5 moles of aluminium react with= moles of chlorine
Mass of chlorine=
2 moles of aluminium produce = 2 moles of aluminium chloride
Thus 0.5 moles of aluminium react with= moles of aluminium chloride
Mass of aluminium chloride=
Thus 53.2 g of chlorine is used and 66.7 g of aluminium chloride is produced.
The correct name for the N3- ion is a nitride ion.
