The equation A + BX = AX + B is the general equation for a...a.
double-replacement reaction.
c.
replacement reaction.
b.
decomposition reaction.
d.
combustion reaction.

Answers

Replacement reaction because one element takes place of another element in a compound.

Final answer:

The equation A + BX = AX + B represents a single-replacement or displacement reaction in Chemistry, where a more reactive element replaces another in a compound to form a new compound and releases the displaced element.

Explanation:

The equation A + BX = AX + B is a representation of a general single-replacement reaction, also known as a displacement reaction in Chemistry. In this type of reaction, a more reactive element (in this case represented by A) displaces or replaces another element (represented by B) in a compound, resulting in a new compound and a separate element as products. Here, A replaces B in the compound BX, leading to the formation of the new compound AX and the release of element B.

What chemical change will occur when a more reactive substance replaces a less reactive substance in a compound? a. Oxidative b. Reduction c. Displacement d. Endothermic

Answers

The correct answer for above statement is:

C. Displacement.

Explanation:

Displacement reaction is a chemical reaction in which a bounteous reactive element replaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example: Reaction of iron nails with copper sulfate solution.a type of chemical reaction wherever an element counters with a compound and takes the position of another element in that compound.
I believe it's C. Displacement.

Predict the organic product formed when phosgene reacts with an excess of methanol.

Answers

When phosgene is reacted with an excess of methanol, this produces dimethyl carbonate. Dimethyl carbonate is used in methylating anilines, phenols, and carboxylic acids, and is also being studied for its use as an alternative additive in fuel.

The industrial production of dimethyl carbonate no longer uses phosgene because of the latter's toxicity. Phosgene widely gained infamy when it was used in chemical warfare during WWI.
