HNO₃(aq) +Ca(OH)₂(aq) --> H₂O(l) + Ca(NO₃)₂(aq)
It is Ca(NO₃)₂ because NO₃ has a charge of -1, and Ca has a charge of 2+. And when writing an ionic compound, you take the charge of 1 and write it as the subscript of the other.
Now let's balance the equation and then find the net ionic equation.
2HNO₃(aq) +Ca(OH)₂(aq) --> 2H₂O(l) + Ca(NO₃)₂(aq)
2H⁺(aq) + 2NO₃⁻(aq) + Ca²⁺(aq) + 2OH⁻(aq) --> 2H₂O(l) + Ca²⁺(aq) + 2NO₃⁻(aq)
We can get rid of the spectator ions. These are the ions that are on both sides.
We are left with
2H⁺(aq) + 2OH⁻(aq) --> 2H₂O(l)
We can simplify the net ionic equation down to
H⁺(aq) + OH⁻(aq) --> H₂O(l)
<span>There are a number of ways
to express concentration of a solution. This includes molarity. Molarity is
expressed as the number of moles of solute per volume of the solution. We calculate as follows:
0.105 mol / L (.0275 L ) = 0.003 mol NaCl
Hope this answers the question. Have a nice day.</span>
Answer:
It would be able to function because the ph of the environment is similar to that of intestine.
Explanation:
The pH of the small intestine is eight. The enzyme would be able to function because enzyme C functions best at a Ph range around 8.
He used a tube of mercury and marked the height of the mercury when placed in an ice bath as 0 degrees celsius, when he placed the tube in a boiling, he marked the height of mercury and called that 100 degrees celsius, he marked it linearly between 0-100 degrees celsius
