Answer:
Explanation In order to calculate the pH, take the negative log of the hydronium ion concentration. To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.
Answer:
Explanation:
A covalent bond is where electrons are shared equally between molecules. if you see the bottom of the page each oxygen is missing 2 electrons so they share two of one of their own with eachother and give oxygen a full octet. it doesnt have to be full to be a covallent bond but it just has to share them evenly rather than keep it to themselves
We are given with
Cobalt phosphate - CoPO4
We are asked for the net ionic equation for the phosphate dissolving in H3O+
The net ionic equation is
CoPO4 (s) + H3O+ (aq) -----> HPO42- (aq) + Co3+ (aq) + H2O *(l)
Volume of a sphere = 4/3 x pi x r^3
When put a fraction of volume constant 4/3 x pi cancels out.
So only cube of radii remains.
Radius of proton = 10^-15 m (Fact; remember it)
Radius of total Hydrogen atom = 0.529 × 10^−10 m
Fraction of Volumes : R'^3/R^3 = (R/R)^3
Fraction = ((10^-15)/(0.529 × 10^−10m.))^3= (1/52900)^3 =
6.755 x 10^-15

Explanation:
Calcium carbide reacts with water to yield acetylene gas and calcium hydroxide as follows;
CaC2(s)+2H2O(g)⇋Ca(OH)2(s)+C2H2(g)
This now shows us that the equation as written in the question is wrong. Since the equation for the reaction of calcium carbide and water as shown in the question is wrong, the equation can not be balanced.
