Answer:
D.141 g
Explanation:
Given that:-
Mass of ethylene = 45.0 g
Molar mass of ethylene = 28.05 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction below:-
1 mole of ethylene produces 2 moles of carbon dioxide
So,
1.60 mole of ethylene produces 2*1.60 moles of carbon dioxide
Moles of carbon dioxide = 3.2 mol
Molar mass of carbon dioxide = 44.01 g/mol
Mass = Moles*Molar mass = 3.2 mol x 44.01 g/mol = 141 g
<u>D.141 g of carbon dioxide will be produced</u>
Answer:
Since the melting point of iron (1538 C) is higher than the Curie point (770 C), the recast iron will lose its original magnetism. After the iron has cooled below the Curie point, it can be re-magnetized.
Answer:
The Moon itself does not generate light; it is lit up by the Sun. As the Moon orbits the Earth, the portion of illuminated Moon that we see changes – giving rise to the phases of the Moon. ... Sometimes the Earth, Moon and Sun are aligned such that the Earth is directly between the Sun and the Moon.
