Answer:
Zero with the subscripts, +2 without them.
Explanation:
Hello!
In this case, since we consider that two silicon are bonded with four oxygen atoms to form silicon oxide according to the following chemical equation:
It is also possible to realize it can be simplified to obtain:
Which means that the total charge with the subscripts is zero, and without the subscripts +2 (+4-2).
Best regards!
<u>Answer:</u> The density of sugar is
<u>Explanation:</u>
To calculate the density of a substance, we use the equation:
We are given:
Mass of sugar = 316 g
Volume of box =
Putting values in above equation, we get:
Hence, the density of sugar is
3 9 0 4 5 4 7 8 9 3 7 2 6 7 1 44 22 9 8 33 1 6 that's all i know from there.
10 * C - low temp, no energy
50 * C - high temp, increased pressure
Lewis Structure of
Oxygen Difluoride is sketched as....
Step 1: Calculate the
total number of valence electrons present in OF₂. This is done by adding all valence electrons of each element. i.e...
Valence e⁻s of Oxygen = 6
Valence e⁻s of Fluorine-1 = 7
Valence e⁻s of Fluorine-2 = 7
------------
Total Valence e⁻s
20Step 2: Draw central element (O) in center surrounded by fluorine atoms. Now, sketch a single bonds between O and both F atoms. Now, subtract 2 electrons per single bond from total valence electrons.. i.e..
Total Valence e⁻s = 20
2 single bonds (2 × 2) = 4
-----------
16Now, distribute remaining 16 electrons on each element to complete its
octet starting from most electronegative element.
Lewis structure of OF₂ is as follow,
