I/3 of 12 = 2/3 of<br>please help at 11 o'clock am it needs to be done ​
Nostrana [21]

Answer:

6

Explanation:

This question is seeking for an equivalent of one expression. The first expression says 1/3 of 12, which means 1/3 × 12 = 4. To find 2/3 of a number that will give us 4, we say

Since; 1/3 of 12 is 4

Then, 4 = 2/3 of x, where x is the number, which when multiplied by two-third (2/3) will result to 4.

4 = 2/3 × x

4 = 2x/3

Cross multiply

2x = 3 × 4

2x = 12

x = 12/2

x = 6.

This means that; 1/3 of 12 = 2/3 of 6

Which is the correct name of a compound that is formed by Si and O?
svp [43]
Naming conventions for 2 non-metals like Si and O are based on their valence electrons,  Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O,  To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"
