The correct answer is polar covalent.

In a covalent bond when two atoms have a difference in electronegativity, then the shared electron is drawn closer towards the atom that has higher electronegativity. For example in HCl, the Cl atom is more electronegative than the H atom. So the shared pair of electron in the H-Cl bond is drawn closer towards the Cl atom causing it have a partial negative charge and the H atom has a partial positive charge.

Polar covalent, it is what happens when there is unequal bond between two atoms, where one has a slightly negative charge and one has a slightly positive charge.

A 0.15 m solution of chloroacetic acid has a ph of 1.86. What is the value of ka for this acid?

Answer: $1.67\times 10^{-3}$

Explanation:

$ClCH_2COOH\rightarrow ClCH_2COO^-+H^+$

cM 0 0

$c-c\alpha$ $c\alpha$ $c\alpha$

So dissociation constant will be:

$K_a=\frac{(c\alpha)^{2}}{c-c\alpha}$

Given: c = 0.15 M

pH = 1.86

$K_a$ = ?

Putting in the values we get:

Also $pH=-log[H^+]$

$1.86=-log[H^+]$

$[H^+]=0.01$

$[H^+]=c\times \alpha$

$0.01=0.15\times \alpha$

$\alpha=0.06$

As $[H^+]=[ClCH_2COO^-]=0.01$

$K_a=\frac{(0.01)^2}{(0.15-0.15\times 0.06)}$

$K_a=1.67\times 10^{-3]$

Thus the vale of $K_a$ for the acid is $1.67\times 10^{-3}$

How do models help scientists predict the polarity of molecules?

Eddi Din [679]

Answer:

Where the greatest electron density is. And isn’t. Look at water. H-O-H.

The oxygen has more electrons, AND 2 lone pairs - the Hydrogens will be partially positive, and so such a way shows the polarity; am arrow with +-> on the Hydrogen area. The “point” will have a negative sign; usually these are drawn as “partially positive” & “partially negative”, but I can’t draw that. Sorry.

at what temperature would 250mL of water boils? 1000mL? is the boiling point an intensive or extensive property? explain.

Ierofanga [76]

Water always boils at 212 degrees F, or 100 degrees C. Because the boiling point is not dependent on the size of the sample of water, it would be an intensive property.

How many moles are there in 270.4 g sample of NaOH

pochemuha

Answer:

6.5

Explanation:

No of moles is the ratio of reacting mass to molar mass

RM - 270.4g

MM - 23+16+1= 40g/mol

270.4/40= 6.76mol
