A 0 Charge. Neutron are neutral in terms of charge
Reactivity. It is the ability of matter to combine chemically with other substances.
Answer:
D.) 2 H₂ + O₂ -----> 2 H₂O
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, coefficients can be added to modify the amount of particular molecules.
A.) Not balanced
2 H₂ + 2 O₂ -----> H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
B.) Not balanced
2 H₂ + 2 O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 4 hydrogen, 2 oxygen
C.) Not balanced
H₂ + O₂ -----> H₂O
<u>Reactants</u>: 2 hydrogen, 2 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
D.) Balanced
2 H₂ + O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 2 oxygen
<u>Products</u>: 4 hydrogen, 2 oxygen
Answer:
The volume of water added is 30 mL
Explanation:
Given data
- Initial concentration (C₁): 0.4 M
- Initial volume (V₁): 10 mL
- Final concentration (C₂): 0.1 M
We can find V₂ using the dilution rule.
C₁ × V₁ = C₂ × V₂
0.4 M × 10 mL = 0.1 M × V₂
V₂ = 40 mL
The volume of water added is
V₂ - V₁ = 40 mL - 10 mL = 30 mL
