A 1.50 liter flask at a temperature of 25°C contains a mixture of 0.158 moles of methane, 0.09 moles of ethane, and 0.044 moles
jok3333 [9.3K]

This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:<span>

P = P1 + P2 + P3
<span>P = (0.08206 atm.L/mol.K)( 298.15 K)/1.50) x (0.158 mole + 0.09 mol + 0.044 mol) = <span>4.76 atm</span></span></span>

What is the concentration of HNO3 if 5.00×10−2 mol are present in 905 mL of the solution?
Zepler [3.9K]

Answer:

0.05525 M or 55.25 mM

Explanation:

Concentration = moles/volume

*Note that volume is expressed in L so you will need to convert mL > L here

C= \frac{n}{V}\\C= \frac{0.05}{0.905}\\C=0.05525

Alkenes can be converted to alcohols by hydroboration‑oxidation. Draw the structure of the alcohol or alcohols formed in the rea
OLEGan [10]

Hydroboration-oxidation is a reaction which follow anti markonikov orientation.

The stereochemistry of hydroboration-oxidation follows syn-adition being a stereospecific reaction. That means that boron and hydrogen are added from the same side.  Then, when the oxidation occurs, the boron is replaced by an hydroxyl having the same geometric position.

2. How do we know if a hypothesis is scientific?
antoniya [11.8K]
The hypothesis can’t be a opinion or something that has nothing to do with your work

For example;if you want to see if your toilet paper is sturdy and you say “i think it will cause the commercial says it does” (wrong) answer would have to be “i infer that the toilet paper will be sturdy because it looks more resistant than other paper I’ve seen”
