The ideal gas law equation is: PV = nRT

Chemistry
1 answer:
nignag [31]3 years ago
8 0

Answer:

The answer is the first option 0.37 moles

Explanation:

the ideal gas law is PV = nRT, so in the terms of n,

n = PV/RT (divide both sides by RT to let n stand alone)

given: P = 700 kpa, V = 2L, T = 450 K , R = 8.31

n = (700 * 2) / (8.31 * 450)

= 1400/3739.5

= 0.34

Why are graphs used to understand an objects motion?
S_A_V [24]
Hello!

Graphs are used to understand an object's motion because they can show the exact location of the object at any given moment. 

This is done with the help of a reference system. The most common reference system is the Cartesian coordinate system, which describes the location of an object through a set of 2 or 3 coordinates (depending if the system is in 2D or 3D).

Studying graphs of movement, we can know if the movement is cyclical, or the direction of the movement, determine tendencies and overall getting an unambiguous and precise understanding of the motion.

Have a good day!

The balanced chemical equation for the reaction of hydrogen and oxygen is shown below. 2H2 + O2 Right arrow. 2H2O The number of
bagirrra123 [75]

Answer:

Equal to 0.253 mol.

Explanation:

Hello,

In this case, since hydrogen and water are in a 2:2 molar relationship, the number of moles of hydrogen necessary to produce 0.253 mol of water will be also 0.253 mol as shown on the following stoichiometric factor:

n_{H_2}=0.253mol H_2O*\frac{2molH_2}{2molH_2O} =0.253mol H_2

Therefore, The number of moles of hydrogen that is needed to produce 0.253 mol of water is equal to 0.253 mol.

Best regards.
