Answer:
The pressure is 4.939 atm
Explanation:
As we know
PV = nRT
where P is the pressure
V is the volume
n is the total number of moles
R is the gas constant
and T is the temperature
Substituting the given values we get -
The pressure is 4.939 atm
(A) nervous, muscular, skeletal
Answer:
A
Explanation:
a heterogeneous mixture is one that is not uniform in composition.It is made up of non-uniform mix of smaller constituent parts that could be separated from one another using various means.
<span>Consider the following reaction:
2CH3OH(g)→2CH4(g)+O2(g)ΔH=+252.8kJ
Calculate the amount of heat transferred when 27.0g of CH3OH(g) is decomposed by this reaction at constant pressure.
27.0 g </span>CH3OH(g) (1 mol/ 32.05g) = 0.84 mol CH3OH(g)
ΔH =+252.8kJ = Q = 0.84 mol (252.8kJ) = 213 kJ
Answer:
An element
Elements are substances that cannot be broken down into simpler substances either by physical or chemical method.
