Answer:
The concentration of that should used originally is
Explanation:
From the question we are told that
The necessary elementary step is
The time taken for sixth of 0.5 M of reactant to react
The time available is
The desired concentration to remain
Let Z be the reactant , Y be the first product and X the second product
Generally the elementary rate law is mathematically as
Where k is the rate constant , is the concentration of Z
From the elementary rate law we see that the reaction is second order (This because the concentration of the reactant is raised to power 2 )
For second order reaction
Where is the initial concentration of Z which a value of
From the question we are told that it take 9 hours for the concentration of the reactant to become
So
=>
For
Answer:Electronegativity, symbolized as χ, is the tendency of an atom to attract shared electrons (or electron density) to itself.
Explanation:
Answer:
4
Explanation:
Speed=Distance/time, so 20/5 divide time divided by distance. so the answer is 4.
Answer:
Option B . heat is taken in
BCAA supplements are commonly taken to boost muscle growth and enhance exercise performance.
They may also help with weight loss and reducing fatigue after exercise. This article contains all the most important information about branched-chain amino acids and their benefits.
<h3><u>What are purposes of Branched-chain amino acids (bcaas) ?</u></h3>
- Leucine, isoleucine, and valine are the three essential amino acids that make up the branched-chain amino acids (BCAAs).
- Since they are vital, your body cannot create them on its own and you must get them through food.
- BCAA supplements have been demonstrated to increase muscular mass, lessen muscle pain, and reduce muscle fatigue.
- They have also been used successfully in hospitals to lessen liver disease symptoms and stop or slow down muscle loss.
- However, since the majority of people consume enough BCAAs from their diets, taking supplements is unlikely to provide any further advantages.
