Answer:
Over time, the plant matter transforms from moist, low-carbon peat, to coal, All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur All this coal comes from mines, which are either underground or run on diesel—a major source of air toxins, nitrogen oxide, and soot.
One mole methane combusts to form one mole CO2 and 2 moles H2O
Answer is 3.306 Pa.
<em>Explanation:</em>
This is a simple unit conversion problem.
1 atm = 760 mmHg = 101325 Pa
Hence,
0.0248 mmHg = (101325 Pa / 760 mmHg) x 0.0248 mmHg
= 3.306 Pa
Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.
The relationships among those units as follows
1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
Answer:
the answer is b, 0.89
Explanation:
A cube has a height of 8 cm and a mass of 457 g. What is its density?
a. 233,984 g/cm
b. 0.89g/cm3
c. 1.12 g/cm3
Density = mass/volume
the volume of the cube is 8X8X8=512cm3
the mass is 457 gm
the density is 457/512 = 0.889 gm/cm3
the answer is b, 0.89
