If two electrons are removed from beryllium during a reaction, which energy level becomes the valence shell?

Chemistry
1 answer:
tino4ka555 [31]3 years ago
3 0

Explanation:

After the electron configuration, the last shell of the beryllium atom has two electrons. In this case, both the valence and valence electrons of beryllium are 2. We know the details about this. The elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation.

What is the percent of hydrogen by mass in CH4O?<br> (H:1.00 amu, C: 12.01 amu, O: 16.00 amu)
cricket20 [7]

The mass percent of hydrogen in CH₄O is 12.5%.

<h3>What is the mass percent?</h3>

Mass percent is the mass of the element divided by the mass of the compound or solute.

  • Step 1: Calculate the mass of the compound.

mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu

  • Step 2: Calculate the mass of hydrogen in the compound.

mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu

  • Step 3: Calculate the mass percent of hydrogen in the compound.

%H = (mH in mCH₄O / mCH₄O) × 100%

%H = 4.00 amu / 32.01 amu × 100% = 12.5%

The mass percent of hydrogen in CH₄O is 12.5%.

Rank the following compounds from highest boiling to lowest boiling. To rank items as equivalent, overlap them.
Olegator [25]

1-pentanol > 1-butanol > 1-chlorobutane > pentane

Explanation:

You my find in the attached picture the structures of the compounds, names and also the variation of their boiling points.

Alcohols have higher boiling points because they form hydrogen bonds between the molecules.
