Morality= wt\m.wt*1000\v(ml)
So the m.wt of h3po4 is 98.00g\ml
Molarity = 32.7g\98.00*1000\455ml
=0.7176
Answer:
Form a chemical bond between two different substances.
Answer:
450cm
50cm
Explanation:
10mm = 1 cm = 0.1 dm = 0.01 m
You always multiply by ten from right to left and divide by ten from the left to the right.
Answer:
6 H⁺ + BrO₃⁻ + 3 Sb³⁺ ⟶ Br⁻ + 3 H₂O + 3 Sb⁵⁺
Explanation:
Step 1: Write the unbalanced reaction
BrO₃⁻ + Sb³⁺ ⟶ Br⁻ + Sb⁵⁺
Step 2: Identify both half-reactions
Reduction: BrO₃⁻ ⟶ Br⁻
Oxidation: Sb³⁺ ⟶ Sb⁵⁺
Step 3: Perform the mass balance, adding H⁺ and H₂O where appropriate
6 H⁺ + BrO₃⁻ ⟶ Br⁻ + 3 H₂O
Sb³⁺ ⟶ Sb⁵⁺
Step 4: Perform the charge balance, adding electrons where appropriate
6 H⁺ + BrO₃⁻ + 6 e⁻ ⟶ Br⁻ + 3 H₂O
Sb³⁺ ⟶ Sb⁵⁺ + 2 e⁻
Step 5: Multiply both half-reactions by numbers that assure that the number of electrons gained and lost is the same
1 × (6 H⁺ + BrO₃⁻ + 6 e⁻ ⟶ Br⁻ + 3 H₂O)
3 × (Sb³⁺ ⟶ Sb⁵⁺ + 2 e⁻)
Step 6: Add both half-reactions and cancel what is repeated in both sides
6 H⁺ + BrO₃⁻ + 3 Sb³⁺ ⟶ Br⁻ + 3 H₂O + 3 Sb⁵⁺
The possible options for the proposed multiplication or division of measurements are:
1. 9.0 km * 7.0 km = 63 km²; this is a correct option because km² is dimensionally correct.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
<h3>What are the possible options among the proposed multiplication or division of measurements?</h3>
The possible options among the proposed multiplication or division of measurements are those which are dimensionally correct.
Considering the given options:
1. 9.0 km * 7.0 km = 63 km²
This is a correct option because km² is dimensionally correct as it is a unit of area.
2. 2.0 g² * 0.043 kg is not correct since there is no unit of square mass.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
In conclusion, the correct measurements options are those that are dimensionally correct.
