Answer:
a soccer ball travels at 3m/s
I think the answer is radiation I am not hundred percent sure though
Answer:
There would be around 2.7*10^24 molecules.
Explanation:
You have to multiply the amount of moles by Avogadro's number to get amount of molecules.
I believe it would be a compound
Answer:
Explanation:
1. Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3
2. FeSO4 + 2 NaOH = Fe(OH)2 + Na2SO4
3. Fe(NO3)3 + 3 NaOH = Fe(OH)3 + 3 NaNO3
For the second part of 3 since it tells us NaOH is excess we dont care about it. We use our balanced equation 3 to get the correct molar ratios to solve this.
1.5mol Fe(NO3)3 x 3mol NaNO3/1mol Fe(NO3)3 x 84.99gNaNO3/1molNaNO3
= 382.455g NaNO3
