Answer:

Option a incompressible

Explanation:

Liquids have definite volume, but indefinite shape.

Liquids take the shape of the container . When a liquid is inside a container, it will take its shape. Unlike gases, a liquid cannot change its volume to spread out and completely fill a container. Hence a liquid cannot be compressed.

Immiscible is not right because this applies only when two liquids are there

Surfectants are compounds that reduce the surface tension between two liquids or a liquid or a gas, etc.

Hence here appropriate choice is

a) incompressible

Rewrite this measurement with a simpler unit, if possible. 8.3 kg•m^2/ s^2

Feliz [49]

Answer: 8.3 J

Explanation:

We have the following measurement:

$8.3 \frac{kg m^{2}}{s^{2}}$

Rearranging the units:

$8.3 \frac{kg m}{s^{2}}m$

Since 1 Newton is $1 N=1 \frac{kg m}{s^{2}}$ :

$8.3 Nm$

Since 1 Joule is $1 J=1 Nm$ :

$8.3 J$ This is the simplest form possible

Draw the structure of bromous acid, hbro2. optimize formal charges.

ArbitrLikvidat [17]

STRUCTURE OF BROMOUS ACID: H–O–Br=O

In this structure, all the elements have a formal charge of zero. The formal charge of each element is calculated below: 

H: 1 – 1/2(2) – 0 = 0
O: 6 – 1/2(4) – 4 = 0
Br: 7 – 1/2(6) – 4 = 0
O: 6 – 1/2(4) – 4 = 0

The equilibrium constant for the reaction is 1.1 x 106 M. HONO(aq) + CN-(aq) ⇋ HCN(aq) + ONO-(aq) This value indicates that

kakasveta [241]

The given question is incomplete. The complete question is given here :

The equilibrium constant for the reaction is $1.1\times 10^6$ M.

$HONO(aq)+CN^- (aq)\rightleftharpoons HCN(aq)+ONO^-(aq)$

This value indicates that

A. $CN^-$ is a stronger base than $ONO^-$

B. HCN is a stronger acid than HONO

C. The conjugate base of HONO is $ONO^-$

D. The conjugate acid of CN- is HCN

Answer: A. $CN^-$ is a stronger base than $ONO^-$

Explanation:

Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.

When $K_{p}>1$ ; the reaction is product favoured.

When $K_{p};$ ; the reaction is reactant favored.

$When K_{p}=1$ ; the reaction is in equilibrium.

As, $K_p>>1$ , the reaction will be product favoured and as it is a acid base reaction where $HONO$ acts as acid by donating $H^+$ ions and $CN^-$ acts as base by accepting $H^+$
