Answer:
The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.
Explanation:
Answer:
a. 52.8
Explanation:
To find the number of moles of HCl we use the relation M₁V₁=M₂V₂
where M₁ is the initial molarity, M₂ the new molarity, V₁ the initial volume used, and V₂ the final volume obtained.
M₁=7.91 M
M₂=2.13 M
V₁=?
V₂=196.1 mL
Replacing these values in the relationship.
M₁V₁=M₂V₂
7.91 M× V₁=2.13 M×196.1 mL
V₁=(2.13 M×196.1 mL)/7.91 M
=52.8 mL
The answer is certain chemical symbols on the periodic table were named not anlyafter the people who discovered them. some of their chemical symbols were even taken from their Latin names. in sodium's case it was taken from it's original Latin name, natrium, as is na.
The carbon atom reduced in the transformation of chloromethane to methyllithium.
The reaction between chloromethane and lithium form methyllithium.
→
In above reaction, methyllithium is formed by the dispersing of lithium metal and adding chloromethane .
The carbon atom in chloromethane is partial positive charge because chlorine is high electronegative atom. The carbon atom in methyllithium is partial negative charge because carbon is more electronegative than lithium.
So, in above reaction two lithium metal donate two electron ( each lithium donate one electron) to the carbon atom(having positive charge) of chloromethane and get negative charge in methyllithium .
The gain of electron is reduction. So,The carbon atom reduced in the transformation of chloromethane to methyllithium.
