atroni [7]

Answer:

Ammonium chloride

Explanation:

The powder is:- Ammonium chloride

When mixed with silver nitrate, white prescipitate of silver chloride is formed as:-

NH_4Cl+AgNO_3\rightarrow NH_4NO_3+AgCl

When mixed with sodium hydroxide, ammonia gas is formed which has noxious order.

NH_4Cl +NaOH\rightarrow NH_3 + H_2O + NaCl

Ammonia gas on reaction with nickel (II) hydroxide forms deep blue colored complex as shown below:-

Ni(OH)_2(s) + 6NH_3(aq)\rightarrow [Ni(NH_3)_6]^{2+}(aq) + 2OH^{-}(aq)

ddd [48]
<span>air = 70 % N2 exhaled air =70%N2 + some less O2 compared to only air 2H2O2=2H2O+O2 NaHCO3=2NaHCO3 → Na2CO3 + H2O + CO2 = No O2 gas from decomposition ssoooo NaHCO3 <exhaled air <air <H2O2

SO sorry for the long wait, hope I helped.

How many ml are in 1.25 l of a intravenous solution of 0.9% sodium chloride?
sweet-ann [11.9K]

Mass % of NaCl = 0.9 % (m/v)

Density of 0.9 % NaCl is about 1.0 g/mL

Volume of NaCl in mL :

1.25 L solution * \frac{1000 mL}{1 L} * \frac{0.9 g NaCl}{100 mL solution}*\frac{1 mL}{1.0 g NaCl}

= 11.25 mL NaCl
