Answer:
I believe the molecular formula is MnBr2·4H2O or Br2H8MnO4
Explanation:
There is acetone, xylene, and toluene in spray paint
Answer:
A. m and n are independent from the molar coefficients of the reactants in the balanced chemical equation.
B. m and n must be determined by experiment.
Explanation:
rate = k[H2O2]^m × [I-]^n
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.
Either the differential rate law or the integrated rate law can be used to determine the reaction order of reactants from experimental data.
Answer:
5.37 L
Explanation:
To solve this problem we need to use the PV=nRT equation.
First we <u>calculate the amount of CO₂</u>, using the initial given conditions for P, V and T:
- P = 785 mmHg ⇒ 785/760 = 1.03 atm
- T = 18 °C ⇒ 18 + 273.16 = 291.16 K
1.03 atm * 4.80 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 291.16 K
We <u>solve for n</u>:
Then we use that value of n for another PV=nRT equation, where T=37 °C (310.16K) and P = 745 mmHg (0.98 atm).
- 0.98 atm * V = 0.207 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 310.16 K
And we <u>solve for V</u>:
