Answer:
0.3195 mole
Explanation:
Number of moles of C3Hg
= mass ÷ molar mass
= 75.6 g ÷ (12 + 12 + 12 + 200.6)
= 75.6 g ÷ 236.6
= 0.3195 mole
Answer:
Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
Explanation:
The Elinino is a group of cyclones that are created by the building up of warm water that builds up along the equator in the Pacific. In the build-up of the Elinino, the warm ocean surface warms the atmosphere which then allows the air that is rich in moisture to rise rapidly and develop into a thunderstorm. This then causes Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
There needs to be the story so that i can work with the 1st question
Answer:
Non of the option applies
Explanation:
Gases may be assumed to obey the ideal gas law, which states that, for pressure P, volume V, number of moles n, and temperature T,
PV = nRT.
where R is the gas constant, and n is the number of mole of gas
If the temperature is held constant, we obtain a simplified version called Boyle's Law, and if the pressure is held constant, we obtain Charles' Law.
Boyle's law:
Boyle's law states that the volume of a given mass of gas is inversely proportional to is pressure, provided that the temperature remains constant.
Mathematically,
P ∝ I/V
∴ PV ∝ 1
From the above mathematical expression, it shows that PV is a constant and does not change with pressure or volume.
∴ non of the options applies
Answer:
The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.
Explanation:
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bond
Between 0.4 and 1.7 then it is Polar Covalent Bond
Greater than 1.7 then it is Ionic Bond
For Fe and S,
E.N of Sulfur = 2.58
E.N of Iron = 1.83
________
E.N Difference 0.75 (Polar Covalent Bond)
