Answer:

See below.

Explanation:

An oxygen atom, in free state has 8 electrons, 2 in the first shell, and 6 in the second. It can only achieve stability if the valency of the valence shell is 0. In order for this, it combines with another atom with the same valency, such as magnesium or another oxygen atom to obey the octet rule. Hope it helps.

When copper crystallizes, it forms face-centered cubic cells. The unit cell edge length is 361.5 pm. Calculate the density of co
Olegator [25]

Density of copper can be calculated using the following formula:

d=\frac{m}{V}

Here, m is mass and V is volume, thus, to calculate density first calculate mass and volume of copper.

In FCC, number of atoms in a unit cell are 4, atomic mass of Cu is 63.546 g/mol and number of atoms in 1 mole is 6.023\times 10^{23}.

Mass of Cu will be:

m=4 atoms\times \frac{1 mol}{6.023\times 10^{23}}\times \frac{63.546 g}{mol}=4.22\times 10^{-22}g

Now, volume can be calculate as:

V=a^{3}

Here, a is edge length.

First convert edge length from pm to cm

1pm=10^{-10}cm

Thus,

361.5 pm=3.615\times 10^{-8}cm

Putting the value,

V=(3.615\times 10^{-8} cm)^{3}=4.72\times 10^{-23} cm^{3}

Now, from mass and volume density can be calculated as follows:

d=\frac{m}{V}=\frac{4.22\times 10^{-22}g}{4.72\times 10^{-23} cm^{3}}=8.932 g/cm^{3}

Therefore, density of copper will be 8.932 g/cm^{3}.

Which is the correct way to write 602,200,000,000,000,000,000,000 in scientific notation?
alisha [4.7K]
<span>The correct way to write 602,200,000,000,000,000,000,000 in scientific notation is 6.202 x 10^23. In the scientific notation, the number is written as a multiplication of a number from 1 to 9 and 10 raised to the adequate power. 602,200,000,000,000,000,000,000 = 6.202 x 100,000,000,000,000,000,000,000. Since 10 = 10^1; 100 = 10^2; 1,000 = 10^3, etc. then 100,000,000,000,000,000,000,000 = 10^23. Therefore, 602,200,000,000,000,000,000,000 = 6.202 x 100,000,000,000,000,000,000,000 = 6.202 x 10^23.</span>
