Hope I be brian list and hope it helps
Answer:
ra to r+a
Explanation: In an enzyme catalyzed reaction, enzyme binds with the active side(3D) of the substrate substrate. It provides an alternative path for the reaction to take place with lower activation energy. in the reaction the kinetic energy of the molecules increases so reaction takes place at a higher rate. when the reaction is completed enzyme leaves the active side.
Silver is in a compound as a reactant, but is a pure element as a product.
Answer: 3M
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Formula used :
where,
n = moles of solute = 0.6 moles
= volume of solution in ml= 200 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be 3M.
1) pOH(solution) = 6.
pOH + pH = 14.
pH = 14 - pOH.
pH = 14 - 6.
pH = 8.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.
This solution is basic, because pH value is greater than 7.
</span>2) [OH⁻] = 10∧(-pOH).
[OH⁻] = 10⁻⁶ M; equilibrium concentration of hydroxide ions.
