The only one I know for sure is Mass is always conserved In a Chemical reaction.
B) O^2-
Hope this helped :)
Answer:
C) 3.3 x 104 grams
Explanation:
1 mole of water contains 6.02 × 10^23 atoms
1.1 × 10^27 atoms will contain;
1.1 × 10^27 ÷ 6.02 × 10^23
= 0.1827 × 10^( 27 - 23)
= 0.1827 × 10^(4)
= 1.827 × 10³ moles of water.
To convert mole to mass in grams, we use the formula;
mole (n) = mass (m) ÷ molar mass (MM)
Molar mas of water (H2O) = 1(2) of H + 16 of O = 18g/mol
mole = mass/molar mass
1.827 × 10³ = mass / 18
mass = 1.827 × 10³ × 18
mass = 32.886 × 10³
mass = 3.286 × 10⁴
mass = 3.3 × 10⁴ grams
Answer:
cis-3-hexene and trans-3-hexene
Explanation:
Hydroboration oxidation is a method of preparation of alcohol from alkene.
Hydroboration follows anti-Markovnikoff rule in which alcohol group attached to less substituted carbon. Stereochemistry of the product is always syn that is H and OH attached to the same side of the double bond.
cis-3-hexene and trans-3-hexene undergoes hydroboration to form 3-hexanol.
Carbohydrates are used for short term energy so it’s gonna be supply energy to the cell, proteins are used for genetic information and building muscles
