When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule?

1 answer:

6 0

Here is the full question with choices: When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule, __________.?

A. the hydrogen atom becomes partially positive

B. the electronegative atom becomes strongly positive

C. the hydrogen atom becomes partially negative

D. the oxygen atom becomes partially negative

The answers are A and D. The oxygen holds onto the electrons more of the time so is slightly negative, making H slightly positive and thus making a polar covalent bond.

How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution

Ganezh [65]

Answer:

0.01932 L

Explanation:

First we <u>convert 105 mM to M</u>:

105 mM / 1000 = 0.105 M

Next we <u>convert 552 mL to L</u>:

552 mL / 1000 = 0.552 L

Then we use the following equation:

C₁V₁=C₂V₂

Where:

C₁ = 3 M

V₁ = ?

C₂ = 0.105 M

V₂ = 0.552 L

We<u> input the given data</u>:

3 M * V₁ = 0.105 M * 0.552 L

And <u>solve for V₁</u>:

V₁ = 0.01932 L

After learning about climate change in her science class, selena wants to make a few changes at home so she can affect climate c

ivanzaharov [21]

Selena can change from burning fossil fuel in her home to using solar energy.

<h3>What causes climate changes?</h3>

Climate change is caused by the release of the greenhouse gases which is gotten through the use and burning of fossil fuels such as coal.

The use of solar panels and solar energy by Selena in her house can help adjust the climate changes by decreasing the amount of greenhouse gases released into the atmosphere.
