Chemistry
1 answer:
ozzi2 years ago
4 0
Answer= 16g

Explanation:-
Convert grams to moles:
No. of moles= mass/molar mass (Mr)

So,
9.7/24=0.40 mols

Now, multiply the mols with the coefficients of Mg and MgO in this way:
0.40 x 2/2= 0.4 mols

Finally, multiply 0.4 mols with the molar mass (Mr) of MgO:
0.4 x 40= 16g

16 grams of MgO.

belka [17]

Answer:

The answer to your question is below

Explanation:

This student is wrong.

Chemical bonds are forces that hold atoms together to form a molecule or compound. These interactions are inside the molecule. Example

What is the frequency of a 4,600 cm wave?
ddd [48]

The frequency of a 4,600 cm wave is 652 Hz

Frequency is the number of waves that pass a fixed point in unit time

Here given data is

Wave =  4,600 cm = 4.6 × 10⁸ nm

We have to calculated frequency = ?

Frequency =v = c/λ

Frequency = 3×10⁸m / 4.6 × 10⁸ nm

Frequency = 652 Hz

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, l, ml, an
vfiekz [6]
First, since l = n-1,
5,4,-5,1/2 and 2,1,0,1/2 are the only answer choices left.
Next, since ml = -l to l,
2,1,0,1/2
is the answer because in 5,4,-5,1/2, the ml value of -5 is not in the range of -4 to 4, as notes by the value 4 for l.
