Answer:
The pressure is 0,97 atm
Explanation:
We apply Boyle Mariotte's Law, where for a certain mass of gas, at constant temperature, the pressure and volume vary inversely proportionally: P1x V1 = P2 x V2 P2= (P1 x V1)/V2
P2 = 1, 50 atm x 5, 00 L /7,74 L
P2= 0, 97 atm
Answer:
Yes A redox reaction can be a combination reaction.
Two elements are mixed in a combination reaction to produce a single product.
Explanation:
Example: water formula
2H2 + O2 → 2H2O
Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.
2H2 + O2 → 2H2O
A resonance dot structure refers to the electrons that are able to switch position. For example Benzene is a resonance structure. It comes down to Pi bonds and how the free electrons are able to move around within a double bonded structure.
Answer:
V = 16.81 L
Explanation:
Given data:
Number of moles = 0.75 mol
Temperature = standard = 273 K
Pressure = 1 atm
Volume of balloon = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will rearrange the formula.
V = nRT/P
V = 0.75 mol ×0.0821 atm.L/mol.K ×273 K / 1 atm
V = 16.81 atm.L/ 1 atm
V = 16.81 L
