Answer:
dentify the common substance that has the highest density. A) glass. B) ethanol. C) aluminum
Explanation:
For the given question above, I think the bond between the carbon atoms is a double bond. <span>2 carbon atoms and 4 hydrogen atoms will give an ethene, which has a C=C bond between carbon atoms. I hope this is the answer you are looking for.</span>
Answer:
The pH is 13,00 and the solution is basic.
Explanation:
<em> </em>The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as
pH = -log (H 30+)
Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:
[H3O ^ +]x [OH ^ -] = 1x 10 ^ -14
[H3O ^ +]x [1.0 10-1]=1x 10 ^ -14
[H3O ^ +]= 1x 10 ^ -14/1.0 10-1M= <em>1.0 10-13 M</em>
pH = -log (H 30+)= -log (1.0 10-13 M)= <em>13, 00</em>
As the pH value is higher than 7, it corresponds to a basic substance.

Answer:
There are 12 nanoseconds in
.
Explanation:
We need to convert
to nanoseconds.
We know that,

Now using unitary method to solve it such that,

So, there are 12 nanoseconds in
.
