47.4% of the number 22 is 10.428.
Hoped I helped!
In the balanced reaction
2 Fe + O₂ → 2 FeO
2 moles of iron (Fe) react with 1 mole of molecular oxygen (O₂) to produce 2 moles of iron oxide (FeO). The ratio of Fe to FeO is 1-to-1, so if one starts with 42.4 mol of Fe, one will end up with the same amount of FeO, 42.4 mol.
Look up the molar mass of Fe and O:
• Fe = 55.845 g/mol
• O = 15.999 g/mol
Then the molar mass of FeO is approximately 71.835 g/mol, and so the mass of 42.4 mol of FeO is
(42.4 mol) × (71.835 g/mol) ≈ 3050 g
Answer:
The first one shows 25%
In the 1st modal, a whole is divided into 4 and 1 of the 4 is selected or highlighted
And as the whole rectangle is 100% and being divided into four its becomes 100/4% and when we solve we get 100/4=25
And thus its the first modal that shows 25%
In the second case its divide into 3 boxes so.. 100/3% and when we solve we get 33.3333333.......and this is not what we want
THEREFORE, THE CORRECT ANSWER IS 1ST MODAL
Answer:
2y(7x + 4z)
Step-by-step explanation:
Consider the common factors of both terms
The gcf of 14 and 8 is 2
The gcf of xy and yz is y
Thus the gcf of both terms is 2y, thus
14xy + 8yz
= 2y(7x + 4z)
