CH3OH (l)

Methanol.

This an alcohol, in ambient temperature is liquid, and in contact with water, they dissolve.

HC2H3O2 (l)

Acetic Acid.

This is a liquid acid, common in vinegar, giving them it's taste and sour flavor.

With water they do not repel, they can create a solution.

C12H22O11 (s)

Sucralose.

This is what we know as a common sugar.

It is a solid that dissolves in water.

A 50.0g g sample of 16n decays to 12.5g in 14.4 seconds. What is its half life

mixas84 [53]

T is amount after time t
Ao is initial amount 
t is time 
HL is half life 

log (At) = log [ Ao x (1/2)^(t/HL) ] 
log (At) = log Ao + log (1/2)^(t/HL) 
log (At) = log Ao + (t/HL) x log (1/2) 

( log At - log Ao) / log (1/2) = t / HL 
log (At/Ao) / log (1/2) = t / HL 

HL = t / [( log (At / Ao)) / log (1/2) ] 

HL = 14.4 s / [ ( log (12.5 / 50) / log (1/2) ] 

HL = 14.4 s / 2 = 7.2 seconds

Which is true about covalent compounds?have a high melting pointconduct electricity when dissolved in waterhave a low boiling po

iris [78.8K]

The correct answer from the choices given is the third option. Covalent compounds have low boiling points. Also, their melting points are low. Covalent bonds have relatively low attractions which results to these properties. The bonds are easily broken by taking energy or adding energy.

Binary molecular (covalent) compounds are formed as the result of a reaction between two nonmetals. Although there are no ions i

ollegr [7]

Answer:

Binary molecular compounds are the compounds consisting of two non-metallic elements. Examples of binary molecular compounds include: NO2, HCl, HF, P2O5 e.t.c.

Rules For Naming Binary Molecular Compounds

Naming binary molecular compounds is quite easy,

1. The first element is given its name.

2. The second element is given its root name (such as, hydro, carb,ox, chlor e.t.c.) followed by suffix ide.

Name of N2O4 - Dinitrogen tetraoxide

Chemical Formula of;

iodic acid: HI

disulfur trioxide: S2O3

dinitrogen monoxide: N2O

hydrofluoric acid: HF

Difference between Binary acid and an oxyacid

An oxyacid is an acid consisting of an oxygen atom bonded to a hydrogen atom and at least one other non-metallic element. Examples of oxyacids include HNO3, H2SO4 e.t.c.

Binary acids are the acids consisting of hydrogen atom bonded to a non-metallic element. Examples include HF, HCl, HI e.t.c.

Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.

Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.
