Answer:- ![4.15*10^-^2^0\mu L](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E0%5Cmu%20L)
Solution:- It is a volume unit conversion problem where we are asked to convert the volume from
to microliters.
We know that:
= 1 mL
![1mL=10^-^3L](https://tex.z-dn.net/?f=1mL%3D10%5E-%5E3L)
and, ![1L=10^6\mu L](https://tex.z-dn.net/?f=1L%3D10%5E6%5Cmu%20L)
Let's use these conversions factors for the desired conversion using dimensional as:
![4.15*10^-^2^3cm^3(\frac{1mL}{1cm^3})(\frac{10^-^3L}{1mL})(\frac{10^6\mu L}{1L})](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E3cm%5E3%28%5Cfrac%7B1mL%7D%7B1cm%5E3%7D%29%28%5Cfrac%7B10%5E-%5E3L%7D%7B1mL%7D%29%28%5Cfrac%7B10%5E6%5Cmu%20L%7D%7B1L%7D%29)
= ![4.15*10^-^2^0\mu L](https://tex.z-dn.net/?f=4.15%2A10%5E-%5E2%5E0%5Cmu%20L)
So, the answer is
.
<u>Reaction</u> :-
CaCO3 + CH3COOH → Ca(CH3COO)2 + H2O + CO2
Yes it is a chemical change as we know that chemical changes result in formation of new substances, and in this reaction calcium acetate, carbon dioxide, and water are produced.
higher temp means higher speed. the will be more energy in the molecules to move, therefore, higher speed
Answer is:increase [Cl₂] and remove HCl from the product.
Chemical reaction: Cl₂ + CH₂Cl₂ → CHCl₃(chloroform) + HCl.
According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of reactants decrease (Cl₂) and concentration of products of chemical reaction increase (CHCl₃) if increase concentration of reactants and decrease concentration of products.
Well, I know one. A positive: decreasing pollution because most people are in quarantine and not outside.
