Look at the mole ratio in the balanced equation
2CO + O2 ==> 2CO2
3.44 mol O2 x 2 mol CO/mol O2 = 6.88 moles CO
Answer:
102kPa
Explanation:
760mmHg = 101.325 kPa
12mmHg = x
Upon converting from mmHg to kPa we have;
x = ( 12 mm Hg x 101.325 kPa) / 760mmHg
x = 1.599868421 kPa
Total pressure = 100.8 kPa + 1.599868421 kPa
Total pressure = 102kPa
A scientist needs to check several parameters before coming
to a conclusion about the amount of water pollution. The scientists needs to
check the amount of dissolved oxygen in the water, temperature of the water,
the clarity of the water, the PH level of the water and also the amount of
bacteria present in the water. There may be other criteria’s, but the mentioned
ones are enough to gauge the amount of pollution in the water. Scientists often
takes fish and aquatic plants from the water to be tested to check the amount
of pollution indirectly affecting these species.
Child psychology is the study of subconscious and conscious childhood development. Child psychologists observe how a child interacts with their parents, themselves, and the world, to understand their mental development.
Answer:
0.488 mol
Explanation:
By the ideal gas law:
PV = nRT
Where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.082 atm.L/mol.K), and T is the temperature in K. Thus, after the reaction:
P = 2.92 atm
V = 4.50 L
T = 55.2°C + 273 = 328.2 K
PV = nRT
n = PV/RT
n = (2.92*4.50)/(0.082*328.2)
n = 0.488 mol
