<h3>What is an ideal gas equation?</h3>The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Given data:
Oxygen produced - 1.618 gram
Decomposition of takes place.
Find - Amount of produced.
The decomposition reaction is as follows -
-->
Moles of gas =
=0.1 moles.
1 mole of is produced from 2 moles of dinitrogen pentoxide
0.1 mole of will be produced from = 0.2 moles.
Now, 2 moles of dinitrogen pentoxide produce 4 moles of
produced will be - 0.4 moles.
Weight of produced - 0.4 X 46
Weight of produced - 18.4 gram
Thus, grams of produced are 18.4
Now calculate the volume of
Given data are:
P=103.25 kPa =1.01899827 atm
T= 22.75 °C +273 = 295.75 K
n=0.4 moles
V=?
R= 0.0821 liter·atm/mol·K
Putting the value in PV=nRT
V =
V =
V= 9.5314 L
Hence, 9.5314 L is the volume of nitrogen dioxide formed at 103.25 kPa and 22.75 °C.

Answer:
The total applied force on the trolley is 5 N toward the North.
Explanation:
In this problem, Ben is pushing the trolley to north and Gary is pushing it to south. So both the forces are acting 180° opposite to each other. As force is a vector quantity, the net force or total force acting on any object should be calculated by vector addition of number of forces along with their directions. So in this case, if we consider the force Ben is applying as F1 and the force Gary is applying as F2 on the trolley. Then the net or total force acting on the trolley will be . This is because, F1 and F2 are acting opposite to each other in direction.Thus,
.
So the total force acting on the trolley is 5 N and it is toward the north direction.
