Answer:
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
MM: 102.89 159.81
2NaBr + F₂ ⟶ 2NaF + Br₂
m/g: 25.4
(a) Moles of Br₂
(b) Moles of NaBr
(c) Mass of NaBr
If Thomson's atomic theory was accurate, the positively charged particles would have gone through the foil. The balanced positive charges and negative charges within the atom would have made the atom neutral, and the positive charges would not have been concentrated enough to cause deflection.
Answer: -
Isopropyl alcohol = 308.95mL
Water = 526.05 mL
Explanation: -
Total volume = 835 mL
Percentage of Isopropyl alcohol = 37%
Volume of Isopropyl alcohol = 835 mL
= 308.95 mL
Since volumes are additive,
Volume of water = Total volume - Volume of Isopropyl alcohol
= 835 - 308.95
= 526.05 mL
Thus, if Isopropyl alcohol is mixed with water to produce a 37.0% (v/v) alcohol solution. 526.05 mL water and 308.95 mL isopropyl alcohol are present in 835 ml of the solution (assuming that volumes are additive).
Answer: I think its B-450 ml
Explanation: you have 8 and need 2 so thats 2 over 8 or 1 over 4, we have 150 ml of 8 so doing a fraction version with ml should work 150 over 450 simplified is 1 over 4 thus theres the answer
plus took the test and it was right sorry if my explamation is confusing
