The formula equation for any reaction is the chemical equation which involves the chemical formulas of the element(s) or compound(s) involved in the reaction. On the left side of the \rightarrow, reactants are written and different reactants are separated by + sign whereas on the right side of the \rightarrow, products are written and different products are separated by + sign. The phases (solid, liquid, or gas) of all the reactants and products are written in brackets after the chemical formula of respective reactants and products.

The formula for fluorine gas is F_2 (g), acts as reactant.

The formula for calcium metal is Ca(s), acts as reactant.

The formula for calcium fluoride is CaF_2 (s), acts as product.

The reaction is written as:

F_2 (g) + Ca (s) \rightarrow CaF_2 (s)

Hence, the formula equation for the reaction is:

F_2 (g) + Ca (s) \rightarrow CaF_2 (s)

Sodium tert-butoxide (NaOC(CH3)3) is classified as bulky and acts as Bronsted Lowry base in the reaction. It is reacted with 2-c
IceJOKER [234]

Answer:but-1-ene

Explanation:This is an E2 elimination reaction .

Kindly refer the attachment for complete reaction and products.

Sodium tert-butoxide is a bulky base and hence cannot approach the substrate 2-chlorobutane from the more substituted end and hence major product formed here would not be following zaitsev rule of elimination reaction.

Sodium tert-butoxide would approach from the less hindered side that is through the primary centre and hence would lead to the formation of 1-butene .The major product formed in this reaction would be 1-butene .

As the mechanism of the reaction is E-2 so it will be a concerted mechanism and as sodium tert-butoxide will start abstracting the primary hydrogen through the less hindered side simultaneously chlorine will start leaving. As the steric repulsion in this case is less hence the transition state is relatively stabilised and leads to the formation of a kinetic product 1-butene.

Kinetic product are formed when reactions are dependent upon rate and not on thermodynamical stability.

2-butene is more thermodynamically6 stable as compared to 1-butene  

The major product formed does not follow the zaitsev rule of forming a more substituted alkene as sodium tert-butoxide cannot approach to abstract the secondary proton due to steric hindrance.

what is the concentration (in %v/v)) of the following solutions? a. 25 mL of ethanol is diluted to a volume of 150 mL with water
fenix001 [56]
The symbol %v/v means percent by volume. Assuming there is no volume effects when these substances are mixed, we calculate as follows:

% v/v = (25 mL ethanol / 25 mL + 150 mL ) x 100
%v/v = 14.29 mL ethanol / mL solution

Hope this answers the question.

How are trials used in an experiment?
DENIUS [597]

Answer:Trials are repetitions of the same procedure. These are done for a couple of reasons: To minimize the impacts of errors done in any one trial by averaging multiple trials together. To minimize random effects and the effects of uncontrolled variables by averaging multiple trials together.
