Answer:

Option D. ZnCl₂ and H₂

Explanation:

From the question given above, the following equation was obtained:

2HCl + Zn —> ZnCl₂ + H₂

Products =?

In a chemical equation, reactants are located on the left side while products are located on the right side i.e

Reactants —> Products

Now, considering the equation from the question i.e

2HCl + Zn —> ZnCl₂ + H₂

The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.

Thus, option D gives the correct answer to the question.

If water is present during the grignard formation, what possible byproduct may form?
Zanzabum

Important of Grignard Reagent :

Grignard reactions are main due to their capacity to form carbon-carbon bonds. Grignard reagents are powerful bases and will react with protic compounds which makes them exceptionally valuable implement for organic synthesis.

Grignard reagents react fastly with acidic hydrogen atoms in molecules such as alcohols and water. When a Grignard reagent reacts with water, a proton return back halogen, and the product is an alkane. The Grignard reagent therefore provides a trace for transforming a haloalkane to an alkane in two steps.

When reacted with water,

RMgX + H2O -------> R-H + MgOH X

R ---- Alkyl Group

X --- Halogen

What is true if a liquid and a gas are in equilibrium?
IRISSAK [1]

Answer:

Recall that, at the boiling point, we observe that both liquid and gas are at equilibrium with one another. This is true at every combination of applied pressure and boiling point temperature. ... The applied pressure will be greater than the vapor pressure, and all of the gas will condense into the liquid

riadik2000 [5.3K]

Answer:

0.94

Explanation:

Let's assume that the total sample of the soil is 1 cm³; which has a porosity of 0.4 cm³; then the original sample of the soil will be 0.6 cm³

The mass  of the soil particles in 1 cm³ of soil + water = 0.75 g

The fraction of the total atrazine can be calculated by the expression;

Total atrazine =C_w(\frac{g}{mL})*V_w(mL)+C_{(soil)}(\frac{g}{soil})*M_{(soil)}(gsoil)

Also; C_{(soil)}(\frac{g}{soil})= K_{oc}(\frac{mL}{gOC})*f_{oc} (\frac{gOC}{gsoil})*C_w(\frac{g}{mL})

NOTE THAT: K_{oc}( \frac{mL}{gOC})=K_{oc}\frac{L}{kgOC}

Total atrazine can now be calculated as:

C_w*0.4+K_{oc}f_{oc}C_w*0.75 = \frac{C_{soil}*M_{soil}}{Total atrazine}

=\frac{K_{oc}f_{oc}C_w*M_{soil}}{C_w*0.4+K_{oc}f_{oc}C_w*0.75} = \frac{0.75*K_{oc}f_{oc}}{0.4+K_{oc}f_{oc}*0.75}

= \frac{10^{2.52}*0.025*0.75}{0.4+10^{2.52}*0.025*0.75}

= 0.94

Thus,the fraction of total atrazine that will be adsorbed to the soil = 0.94.

Which of the following statements best explains why atoms bond?
Keith_Richards [23]

Answer:

atoms bond to attain neutral configuration or to get noble gas configuration.

Explanation:

atoms always want to be stable by attaining noble gas configuration.

they do so by forming bonds. they also bond to each other to make their outer electrons  stable that is if the atom has an excessive electron than its neutral configuration it can bond to another atom that has one less electron than its neutral configuration by ionic bond.
