Answer:
The limiting reagents seemed to be those that were consumed first
.
Because when this reagent is consumed, the reaction stops. The quantity of this determines the total quantity of the product formed.
Explanation:
A limiting reagent is one that is consumed in its entirety. In this way, it delimits the amount of product that can be formed.
Take the case of two substances that interact and produce a chemical reaction. If one of the substances runs out as it is consumed during the process, the reaction will stop. The reagent consumed acts as a limiting reagent, that is, it limits the possibility of the reaction proceeding, and therefore it also limits the amount of the product generated by the reaction.
Solution contains 45% salt
She wants to obtain 180 ounces of a mixture that
is 30% salt
Ounces of water with 45% salt solution = ?
30% = 0.3 and 45% = 0.45
Let V is the volume of water to be mixed in
ounces, then the volume of the 45% salt solution needed is 180-V
The balanced equation for the mass of salt is
0.45 x (180-V) = 0.3 x 180
81 – 0.45V = 54
0.45V = 81-54
0.45V = 27
V = 60
<span>So, 60 ounces of water is needed</span>
KH2O? Maybe that will work?
Elevated carbon dioxide mean too much acid in the blood. <span>Increase acid excretion (intercalated cells secrete H+ into tubules) and decrease bicarbonate excretion. They also make new bicarbonate to add to the plasma.</span>
