A, milligrams because rice is very small therefore you'd need to use a very small unit of measurement.
V(NaOH)=15 mL =0.015 L
C(NaOH)=0.1 mol/L
C(H₂SO₄)=0.05 mol/L
2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O
n(NaOH)=V(NaOH)C(NaOH)=2n(H₂SO₄)
n(H₂SO₄)=V(H₂SO₄)C(H₂SO₄)
V(NaOH)C(NaOH)=2V(H₂SO₄)C(H₂SO₄)
V(H₂SO₄)=V(NaOH)C(NaOH)/{2C(H₂SO₄)}
V(H₂SO₄)=0.015*0.1/{2*0.05}=0.015 L = 15 mL
Answer:
24.3
Explanation:
I used a calculator and did 3x3x3=27 27x0.90=24.3
Answer:
It represents the <em>number of atoms</em> of that particular element present in the compound. In C₂H₄O₂ there are 2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms.
Answer:
The formation of large molecules from small repeating units is known as <u>Condensation</u> reactions.
Explanation:
Those reactions in which two molecules join together with a elimination of small neutral molecule like H₂O, CH₃OH, HCl e.t.c are known as condensation reactions.
Polymerization reactions are those reactions in which small molecules called as monomers join together to form a large molecule also known as polymers. These reactions are done via different mechanisms among which one is the condensation reaction.
Example:
Proteins (polymer) are made up of amino acids (monomers) through condensation reaction as,
n H₂N-RH-COOH → H₂N-[-RH]n-COOH + n H₂O
In above equation "n" represent large number, H₂N-RH-COOH represent amino acid (monomer) and H₂N-[-RH]n-COOH represent protein (polymer). While, the H₂O eliminated is the small neutral molecule.
