Answer:

Yes, given statement is true.

Explanation:

Given that a cylinder of 1000 ml is marked at every 100 ml.

During the test, the student can easily check the volume of liquid so the student's guess is 750 ml true.  

With this measurement, we can estimate that 1/10th of 100 ml can be measured.  

So, given statement is correct.

Lakshmi has a sample of ammonium nitrate (NH4NO3) that has a mass of 40.10 g. She knows that the molar mass of NH4NO3 is 80.0432
avanturin [10]
The answer is 0.5010

Number of moles (n) is equal to the quotient of mass (m) and molar mass of a sample (Mr):
n = m/Mr

We have:
n = ?
m = 40.10 g
Mr = 80.0432 g/mol

n = 40.10 g : 80.0432 g/mol = 0.5010

<span>40.10 has 4 significant digits,
</span><span>80.0432 has 6 significant digits.
Since 4 is less than 6, we choose 4 </span>significant digits

What is the maximum number of electrons that can be contained in the first, second, third, and fourth energy levels, respectivel
fenix001 [56]
<span>The maximum number of electrons that can be contained in an energy level (also called shells) is determined by the formula 2n^2, where n is the energy level; So, when n = 1, the maximum number of electrons is 2; when n = 2, the maximum number of electrons is 2*(2^2) = 8; when n = 3, the maximum number of electrons is 2 * (3^2) = 18; and when n=4, the maximum number of electrons is 2(4^2) = 32. So, briefly the series is 2, 8, 16, 32.</span>

The molecule CH₂O contains two single bonds and one double bond. True or false
Tamiku [17]

Answer:

<em>The answer to your question is </em><em>True</em>

Explanation:

CH2O is a polar molecule. It has three polar bonds that are arranged asymmetrically, thus allowing their dipole moments to add up and give the molecule an overall dipole moment. CH2O has a central carbon atom that forms two single bonds with the two hydrogen atoms and a double bond with the oxygen atom.

<u><em>I hope this helps and have a good day!</em></u>
