The solution would be like this for this specific problem:
4 NaOCl + S2O3{2-} + 2
OH{-} → 2 SO4{2-} + H2O + 4 NaCl
<span>(0.00456 L) x (0.100 mol/L
S2O3{2-}) x (4 mol NaOCl / 1 mol S2O3{2-}) x (100.0 mL / 25 mL) x </span><span>
<span>(74.4422 g NaClO/mol) = 0.54313 g </span></span>
<span>(5.00 mL) x (1.08 g/mL) =
5.40 g solution </span>
(0.54313 g) / (5.40 g) =
0.101 = 10.1%
So, the average percent by mass of NaClO in the
commercial bleach is 10.1%.
Answer:
I think it is iron conducts electricity and heat
Answer:
0.21 kg
Step-by-step explanation:
Volume of cola = 2.0 L × (33.8 fl oz/1L)
= 67.6 fl oz
Grams of sugar = 67.6 fl oz × (25 g sugar/8.0 fl oz)
= 210 g sugar
Kilograms of sugar = 210 g × (1 kg/1000 g)
= 0.21 kg

Answer : The final pressure of the basketball is, 0.990 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure = 1.10 atm
= final pressure = ?
= initial temperature = 
= initial temperature = 
Now put all the given values in the above equation, we get:
Thus, the final pressure of the basketball is, 0.990 atm
