Answer:
Explanation:
Ideal gases follow the combined law of gases:
Where,
- Pressure is the absolute pressure and its units may be in any system, as long as they are the same for both states.
- Also, volume may be in any units, as long as it they are the same for both states.
- Temperature must be absolute temperature, whose unit is Kelvin.
Your data are:
- P₁ = 1200.00 mmHg
- P₂ = 1.11842 atm
- V₁ = 85.0 mL
- V₂ = 350.0 mL
- T₂ = ?
- T₁ = 90.0ºC
<u>1. Conversion of units:</u>
- P₁ = 1200.00 mmHg × 1.00000 atm / 760.000 = 1.578947 mmHg
- T₁ = 90.00ºC + 273.15 = 363.15K
<u>2. Solution</u>
- Clearing T₂, from the combined gas equation you get:
Explanation:
The temperature has no effect on the speed of the
particles.
The answer would be 5.5g because you have to subtract 8.2 minus 2.7 and you get 5.5g so basically the answer is C.
Answer:
True. An English scientist by the name of John Newlands tried to classify the elements in a unique manner. He first started by arranging all the elements in a ascending order according to their atomic weights.
Answer:
3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)
Explanation:
Step 1: RxN
NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + NaNO₃ (aq)
Step 2: Balance RxN
We need 3 OH's on both sides.
We also need 3 NO₃'s on both side.
- This will make it so we also need 3 Na's on both side
3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)
