Which of the following occurs when a covalent bond forms? Which of the following occurs when a covalent bond forms? Partial char
Alexus [3.1K]

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the bond which occurs due to sharing of electrons between the combining atoms.

Generally, a covalent bond is formed between non-metals.

For example, both nitrogen and oxygen atoms are non-metals and they combine covalently to form NO_{2} compound.

As nitrogen has 5 valence electrons and an oxygen atom has 6 valence electrons. So, there occurs unequal sharing of electrons between the two.

Thus, we can conclude that when a covalent bond forms then electrons in valence shells are shared between atoms.

<u>Chemistry</u>

<u>Stoichiometry</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 2NaOH (s) + CO₂ (g) → Na₂CO₃ (s) + H₂O (l)

[Given] 1.85 mol NaOH

<u>Step 2: Identify Conversions</u>

[RxN] 2 mol NaOH → 1 mol H₂O

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

<u>Step 3: Stoichiometry</u>

  1. Set up:                               \displaystyle 1.85 \ mol \ NaOH(\frac{1 \ mol \ H_2O}{2 \ mol \ NaOH})(\frac{18.02 \ g \ H_2O}{1 \ mol \ H_2O})
  2. Multiply/Divide:                 \displaystyle 16.6685 \ g \ H_2O

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

16.6685 g H₂O ≈ 16.7 g H₂O

A 253 g block of wood has the following dimensions: Length 15.24 cm Width 6.64 cm Height 3.56 cm What is the density of the wood
yanalaym [24]

Answer:

0.7 g/cm³

Explanation:

<em>hey there,</em>

<em />

< The formula for density is p = \frac{m}{v}  where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make \frac{m}{v} (if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)

We already know that the block is 253 g so the mass is 253 g.

To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.

15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³

Now plug it into the formula.p = \frac{m}{v}=\frac{253}{360.25} = 0.7 g/cm³ >

<u>Hope this helped! Feel free to ask anything else.</u>
