Which of the following is an aldehyde?

balu736 [363]

Answer: $CH_3CH_2CH_2CHO$ has aldehyde functional group.

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

A. $CH_3CH_2CH_2COCH_3$ has ketone $C=O$ functional group .

B. $CH_3CH_2CH_2COOH$ has carboxylic acid $COOH$ functional group .

C. $CH_3CH_2CH_2CHO$ has aldehyde $H-C=O$ functional group .

D. $CH_3CH_2CH_2COOCH_3$ has ester $RO-C=O$ functional group .

Thus $CH_3CH_2CH_2CHO$ has aldehyde (CHO) group.

Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of calcium iodide and c

Hitman42 [59]

Answer: The net ionic equation is written below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:

$3CaI_2(aq.)+Cr_2(SO_4)_3(aq.)\rightarrow 3CaSO_4(s)+2CrI_3(aq.)$

Ionic form of the above equation follows:

$3Ca^{2+}(aq.)+6I^{-}(aq.)+2Cr^{3+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)+2Cr^{3+}(aq.)+6I^-(aq.)$

As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$3Ca^{2+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)$

Hence, the net ionic equation is written above.

Cucl2(aq)+na2s(aq)→cus(s)+2nacl(aq) Write the net ionic equation for this reaction.

Rudiy27

Answer:

Cu^2+ (aq) + S^2- (aq) --> CuS (s)

Explanation:

Break up all the soluble compounds into their constituent ions to get the complete ionic equation, and cross off the ones that appear the same on both sides:

Cu (aq) + 2Cl(aq) + 2Na (aq) + S (aq) --> CuS (s) + 2Na (aq) + 2Cl (aq)

2Cl and 2Na appear on both sides of the arrow, so cross those out to get the net ionic equation.
