Answer:
its a option neutralization takes place between acid and base plz mark me branliest
First, is to solve the molar mass of the herbicide, with a formula
<span>C3H8NO5P
C3 = 12 ( 3 ) = 36
H8 = 1 ( 8 ) = 8
N = 14
O5 = 16 ( 5 ) = 80
P = 31
so in total the molar mass of </span><span>C3H8NO5P is 36 + 8 + 14 + 80 + 31 = 169 g/mol
number of moles = 783.5 g ( 1 mol / 169 g)
number of moles = 4.64 mol </span><span>C3H8NO5P</span>
It should be watts. <span>A </span>watt<span> is the number of </span>joules generated per second. <span>A kilocalorie is 4,184 </span>joules<span>, the amount of energy that will heat 1 kilogram of water by 1 degree </span>Celsius<span>. </span>
Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels.
Answer:
pH = 5.58
Explanation:
Given that :
Citric acid is a triprotic acid with the formula 
. Tripotic acids are acids that have the tendency to yield three protons per molecule during the phases of dissociation, therefore they have three pka.
For Citric acid; the pka values are:
So, the pH of sodiummonohydrogencitrate with the chemical formula 
which can act as an acid and a base (i.e it is said to be amphoteric) can be calculated as :
pH = 5.58
Therefore, the approximate pH of a solution of sodium monohydrogencitrate = 5.58
