Answer:
A. They are malleable, ductile, and conduct electricity.
Explanation:
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.
Mass of the of sample using the balance is 433.2 g
You can estimate the decimal part because it not exactly 3
400 + 30 + 3.2
To find the density of the sample you divide mass / volume = density
Mass = 433.2 and Volume = 65.6ml 433.2 g / 65.6
6. 6 g/ml^3
Density = 6.6 g / ml^3 and Mass = 433.2 g
