Answer:
NaF(aq)
Explanation:
When sodium bromide react with fluorine sodium fluoride is formed. Florine is more reactive than bromine that's why it displace the bromine and form compound with sodium.
Chemical reaction:
NaBr(aq) + F₂(aq) → NaF(aq) + Br₂(aq)
Balanced chemical equation:
2NaBr(aq) + F₂(aq) → 2NaF(aq) + Br₂(aq)
Sodium is alkali metal and have one valance electron. It loses one electron and show +1 charge. While all halogen elements need one electron to complete the octet and show -1 charge.
That's why one halogen atom is combine with one sodium atom to make overall compound neutral.
Answer:
The mass of CO in 12,000 Liters of air is 
.
Explanation:
The ppm is the amount of solute (in milligrams) present in one Liter of a solvent. It is also known as parts-per million.
To calculate the ppm of oxygen in sea water, we use the equation:
The ppm concentration of CO = 10 ppm
Mass of CO = m
Volume of air = 12,000 L
The mass of CO in 12,000 Liters of air is .
The product of replacement reaction of 2Fe + 3 CUSO4 yield 2Fe(SO4)3 + 3 Cu
during replacement reaction involve replacement of less reactive element in the reactivity series from its compound. Fe is more reactive in the reactivity series than cu therefore it Fe replaces cu from CUSO4
