He said that he was soryy he was late

He said that he was sorry he was late, because the car wouldn`t start. или He said that he was sorry he was late and that the car wouldn`t start.

2NaOH (концентрир. ) + CO2 → Na2CO3 + H2O NaOH (разбавлен. ) + CO2 → NaHCO3 6NaOH (разбавлен. ) + P2O5 → 2Na3PO4 + 3H2O NaOH (разбавлен. ) + H3PO4(концентрир. ) → NaH2PO4 + H2O 3NaOH (концентрир. ) + H3PO4 (разбавлен. ) → Na3PO4 + 3H2O 2NaOH + CuCl2 → Cu(OH)2 + 2NaCl 2NaOH + CuCl2 (t)→ CuO↓ + H2O + 2NaCl
