Moles of helium is required to blow up a balloon to 87.1 liters at 74 C and 3.5 atm is 021.65 mole
Mole is the unit of amount of substances of specified elementary entities
According to the ideal gas law he number of moles of a gas n can be calculated knowing the partial pressure of a gas p in a container with a volume V at an absolute temperature T from the equation
n =pV/RT
Here given data is volume = 87.1 liters
Temperature = 74 °C means 347.15 k
Pressure = 3.5 atm
R = 0.0821
Putting this value in ideal gas equation then
n =pV/RT
n = 3.5 atm×87.1 liters / 0.0821 ×347.15 k
n = 021.65 mole
Moles of helium is required to blow up a balloon to 87.1 liters at 74 C and 3.5 atm is 021.65 mole

No reaction would occur because copper is more active than silver and silver would be unable to donate electrons to copper.
Answer:
The number of valence electrons increases from top to bottom within each group.
Explanation:
The valence electrons are the outermost shell electrons.
Therefore, the number of valence electrons does not increase from top to bottom within each of the group.
Down a group, the number of valence electrons remains the same.
For group I elements, the number of electrons is 1.
The group is the vertical arrangement of elements.
From left to right across a period, the number of valence electrons increases because you move from group to group.
<u>Answer:</u> The equilibrium constant for the given reaction is 4.224
<u>Explanation:</u>
We are given:
Equilibrium concentration of water = 0.250 M
Equilibrium concentration of hydrogen gas = 0.330 M
Equilibrium concentration of oxygen gas = 0.800 M
For the given chemical reaction:
The expression of for above reaction follows:
Putting values in above expression, we get:
Hence, the equilibrium constant for the given reaction is 4.224
