Answer:
O2+H2 → H2O
become→zero to−2
∵ it will be reduced and oxidation state of H
2
becomes zero to +1 it will be oxidised.
∴ reaction will be redox

Answer:
The correct answer is - 0.570 grams
Explanation:
The balanced chemical reaction is given by
Cu(NO3)2(aq) + 2NaOH(aq) --------> Cu(OH)2(s) + 2NaNO3(aq)
1.0 mole 2.0 mole 1.0 mole 2.0 mole
number of mol of Cu(OH)2,
n = Molarity * Volume
=
millimoles
As clear in the equation, 1 mole of Cu(NO3)2 gives 1 mole of Cu(OH)2
, So, 5.845 millimoles of Cu(NO3)2 will produce 5.845 millimoles of Cu(OH)2
Mass of Cu(OH)2 = number of mol * molar mass
= 
= 0.570 grams
Thus, the correct answer is - 0.570 grams
1 kg ---------- 1000 g
4.84 kg ------ ?
4.84 x 1000 / 1 => 4840 g
D = m / V
7.86 =4840 / V
V = 4840 / 7.86
V = 615.77 cm³
1 cm³ ------------ 0.01 dL
615.77 ----- ?
615.77 x 0.01 / 1
= 6.1577<span> dL</span>
