помогите пожалуйста,срочно надо

Cu(NO3)2=CuOHNO3=Cu(OH)2=CuO=CuSO4

Answer 1

$Cu(NO_{3})_{2} - CuOHNO_{3} - Cu(OH)_{2} - CuO - CuSO_{4}\ \</p><p>1) : Cu(NO_{3})_{2} + NaOH = CuOHNO_{3} + NaNO_{3}\</p><p>2) : CuOHNO_{3} + NaOH = Cu(OH)_{2} + NaNO_{3}\</p><p>3) : Cu(OH)_{2} = CuO +H_{2}O\</p><p>4) : CuO + H2SO_{4} = CuSO_{4} + H_{2}O$
