The french fries gives 460 kilocalories and <span>65% of those calories come from fat. Then, calorie that comes from fat would be: 65% * 460 kcal= 299 kcal
Fat gives </span>energy about 9kcal/gram. Then, the total mass of fat in the french fries would be: 299 kcal/ (9kcal/g)= 33.22 grams
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.
The solute is the substance that you put into water to dissolve.
<em>Displacement reactions</em>
Answer:the mass of the gases and ash should be equal the mass of the initial stack of newspapers, there are equal number of atoms on both sides
Explanation:no matter what form the newspaper would take the mass stays the same because all you did is burn it, conserve means that each atom's mass will stay the same no matter what.
