125 pounds = 56.6990463 kilograms
Explanation:
A) sulfuric acid + sodium hydroxide → sodium sulfate + water
Answer:
14 moles of CO are needed in the reaction, to react with 7 moles of O₂
Explanation:
We need to determine the reaction to start:
O₂ (g) + 2CO (g) → 2CO₂ (g)
Now, we state the ratio of reactants:
1 mol of oxygen needs 2 moles of CO, to react and they both, produce 2 moles of CO₂. Therefore the ratio is 1:2
We can make a rule of three to reach the answer:
1 mol of O₂ needs 2 moles of CO to react
Therefore, 7 moles of O₂ must need (7 .2) /1 = 14 moles
Answer:
1) 100
2) 22
3) 39
4) 6
5) 2b + 6
6) 8
7) 4n + 20
Explanation:
If B is the midpoint of AC and C is the midpoint of BD, means that all 3 parts are equal. AB = BC = CD
1) If AB = 50 then AC = AB + BC = 50 +50 = 100
2)if BD = 44 then is CD = 44 - BC ⇔ CD = 44 - 22 = 22
3) if AC = 26 and AC = AB + BC then each part is 13
AD = AC + CD = 26 +13 = 39
4)if CD = 6 then AB = 6 Because all single parts are equal
5) if AC = 4b + 12 then is AB the half of it = 2b +6
6) if AD = 24 then AB = 1/3 of it = 8
7)if BC is 2n + 10 then is AC = 2x BC = 4n + 20
Answer:
ionic bond
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
