Answer: The Earth is an oblate spheroid which is more elongated along the equator.

Regions along the equator receives more amount of direct sunlight from the sun causing higher temperatures along the region. While places along the poles receives less amount of heat since heat is scattered in a larger area due to the shape of the Earth around the poles.

Explanation: So places along the equator experiences higher temperature due to the direct hit of sunlight. And places along the polar regions experiences cooler temperature since it receives less amount of sunlight.

The following two reactions are important in the blast furnace production of iron metal from iron ore (Fe2O3):2C(s) + O2(g) -&gt

Inga [223]

Answer: A) 67.1 moles

Explanation:

The balanced reaction is :

$2C(s)+O_2(g)\rightarrow 2CO(g)$

$Fe_2O_3+3CO(g)\rightarrow 2Fe+3CO_2$

To calculate the moles, we use the equation:

$\text{Number of moles of iron}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{5.00\times 1000g}{56g/mol}=89.3moles$

According to stoichiometry;

2 moles of iron is produced by 3 moles of carbon monoxide

89.3 moles of iron is produced by= $\frac{3}{2}\times 89.3=134$ moles of carbon monoxide

2 moles of carbon monoxide is produced by = 1 mole of oxygen

Thus 134 moles of carbon monoxide is produced by = $\frac{1}{2}\times 134=67.1$ moles of oxygen

A compound with a molar mass of 102.133 g/mol contains an element with a subscript of 5 . the element is 58.80 g per 100.0 g com

VLD [36.1K]

Answer:

12.0108408

Explanation:

Denote the element with a letter like say X. Since it has a subscript of 5, then, X5.

Molecular mass=102.133g/mol.

% of X in compound =58.8/100

=0.588

Mass of X in the compound = 0.588*102.133 ( the % of X in compound * molar mass of compound)

= 60.054204

X5=60.054204

Then element X has a mass of 60.054204/5=12.0108408
