Covalent bonded atoms make up what

White raven [17]

In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

There is 35 mg of sodium in a can of Coke. You determine it to be 28 mg. What is your percent error?

natali 33 [55]

Answer:

The answer is

<h2>20 %</h2>

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual volume = 35 mg

error = 35 - 28 = 7

The percentage error is

$P(\%) = \frac{7}{35} \times 100 \\ = \frac{1}{5} \times 100 \\ = 20$

We have the final answer as

<h3>20 %</h3>

Hope this helps you

julia-pushkina [17]

Every 2 million years the amount is halved
0 million = 200g
2 million = 200g/2 = 100g
4 million = 100g/2 = 50g
