you need to <u>lose one electron </u>
Answer:
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
Mᵣ: 98.08 392.18
2Cr + 3H₂SO₄ ⟶ Cr₂(SO₄)₃ + 3H₂
To solve the stoichiometry problem, you must
- Use the molar mass of H₂SO₄ to convert the mass of H₂SO₄ to moles of H₂SO₄
- Use the molar ratio to convert moles of H₂SO₄ to moles of Cr₂(SO₄)₃
- Use the molar mass of Cr₂(SO₄)₃ to convert moles of Cr₂(SO₄)₃ to mass of Cr₂(SO₄)₃
a) Mass of Cr₂(SO₄)₃
(i) Mass of pure H₂SO₄
(ii) Moles of H₂SO₄
(iii) Moles of Cr₂(SO₄)₃
The molar ratio is 1 mol Cr₂(SO₄)₃:3 mol H₂SO₄
(iv) Mass of Cr₂(SO₄)₃
b) Percentage yield
It is impossible to get a yield of 485.9 g. I will assume you meant 185.9 g.
70 bags is the answer.
They add “They put 7 pieces of candy in each bag to throw you off”
To find the answer just divide 28 bags by 4 days to get how many bags they make in 1 day. Take that number “7” and multiply it by 10 days. The answer is then 70.
Actually, a methylene group is simply any compound which
contains a C=C double bond group and the rest are single bonded carbon groups. Some
example of the isomers of C6H12 which contains methylene group is:
1-hexene
2,3-dimethyl-2-butene
2,3-dimethyl-1-butene
2-methyl-2-pentene
trans-2-hexene
4-methyl-1-pentene
cis-2-hexene
trans-3-hexene
2-ethyl-1-butene
2-methyl-1-pentene
3,3-dimethyl-1-butene
4-methyl-cis-2-pentene
cis-3-methyl-2-pentene
trans-3-methyl-2-pentene
Explanation:
The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. ... To allow motion, different bones are connected by joints.
