Answer:

ice and water on the ground affect incoming solar radiation by reflecting 4 percent of solar radiation that reaches the surface. the state of water and the sun angle are vital in determining the amount of reflection that take place. at low sun angle and at times when the surface is ice, more reflection occurs.

The distance between the centers of the two oxygen atoms in an oxygen molecule is 1.21 x 10-8 cm. What is this distance in inche

Sergio [31]

Answer:

$d=4.75\times 10^{-9}\ \text{inches}$

Explanation:

Given that,

The distance between the centers of the two oxygen atoms in an oxygen molecule is $1.21\times 10^{-8}\ cm$ .

We need to convert this distance in inches.

We know that,

1 cm = 0.393 inches

We can solve it as follows :

$1.21\times 10^{-8}\ cm=0.393\times 1.21\times 10^{-8}\\\\=4.75\times 10^{-9}\ \text{inches}$

So, the distance between the centers of the two oxygen atoms is $4.75\times 10^{-9}\ \text{inches}$ .

What is the theoretical yield of SO3 produced by 8.96 g of S?

Virty [35]

Answer: Theoretical yield of $SO_3$ produced by 8.96 g of S is 33.6 g

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} S=\frac{8.96g}{32g/mol}=0.28moles$

The balanced chemical equation is:

$2S+3O_2\rightarrow 2SO_3$

According to stoichiometry :

2 moles of $S$ produce = 3 moles of $SO_3$

Thus 0.28 moles of $S$ will produce= $\frac{3}{2}\times 0.28=0.42moles$ of $SO_3$

Mass of $SO_3=moles\times {\text {Molar mass}}=0.42moles\times 80g/mol=33.6g$

Thus theoretical yield of $SO_3$ produced by 8.96 g of S is 33.6 g

If the exact outer limit of an isolated atom cannot be measured, what criterion can we use to determine atomic radii? What is th

Alik [6]

Answer:

Calculate the atomic radii of two touching or overlapping atoms.

Explanation:

No doubt, we can't find the atomic boundary of a single atom, but when atoms are in the form of pairs it becomes very easy to measure the atomic radii of two and then dividing it by 2 to get an estimate of atomic radius of a single atom.

It is also called as covalent radius which is half of the total inter-nuclear distance between two same bonded atoms (Homo-nuclear).

If two adjacent mettalic ions are joined by such pairing then the same half of the distance between the nucleus is termed as metallic radii.
