Hi hi hello hi hey hey do khan know if I have any pictures I have a picture of you
The chemical formula of nitrogen dioxide is NO2. It is a brown coloured gas.
Answer:
0.0705 moles NaClO
Explanation:
<em>Assuming the bleach solution are 100mL:</em>
First, we need to find the mass of the solution knowing density = 1.0g/mL:
100mL * (1g/mL) = 100g
Then, we must find the mass of NaClO in 100g of solution using its percentage by mass:
100g * (5.25g NaClO / 100g) = 5.25g NaClO
As the last point, we need to convert the mass to moles using molar mass of NaClO = 74.44g/mol:
5.25g NaClO * (1mol/74.44g) = 0.0705 moles NaClO
Answer:
That is NOT true!
Explanation:
No matter how little or big amount of waste you add, it is still pollution, and it adds to the big amount that is already there.
Chemical equation:
M ( Na ) = 23 g/moles ( 2 moles Na = 46 g )
M ( Cl 2 ) = 71 g/moles ( 1 mole Cl 2 = 71 g )
so Na needs more Cl 2 to react;
96 : x = 46 : 71
46 x = 6816
x = 6816 : 46
x = 148.17 g
Answer:
the mass of chlorine gas is 148.17 g.
