The formula equation is Ca + F2 = CaF2.
Hope it helps.
You need the molercular mass of Sucrose.
You can either search the molecular formula of Sucrose and calculate the molecular mass, or search directly the molecular mass.
Here you have both:
Molecular mass of sucrose: 342.30 g / mol
Chemical formula of sucrose: C12 H22 O11 (if you want to just must multiply the number of each atom by its atomic mass to get the molecular mass).
Calculate the number of grams of O in that molecule:
O: 11 * 16.00 g/mol = 176.0 g of O.
Now use proportions:
176 g O / 342.30 g sucrose = x / 50.00 g sucrose
=> x = 50.00 g sucrose * 176.0 g O / 342.30 g sucrose =25.71 g O.
Answer: 25.17 g
Answer:
B: 3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
Explanation:
Potassium hydroxide (KOH) reacts with iron (III).
The normal balanced equation is;
Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3
Now the ionic equation will be;
3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
A real gas will reach an absolute zero at some point due to it being a limited resource, while an ideal will not.
Answer: CF4 is the formula
