Question

give a balanced equation for the folowing:
1)methane burns in oxygen
2)sodium piece is added to water
3)barium chloride reacts with sodium sulphate
4)carbonmonoxide combines with hydrogen forrming methyle alcohol at apressure of 340 atmosphere

Answer 1

1) CH4 + 2O2 = CO2 + 2H2O
2) 2Na + 2H2O = 2NaOH + H2↑
3) BaCl2 + Na2SO4 = BaSO4↓ + 2NaCl
4) CO + 2H2 =(pressure)= CH3OH
