Answer:

honey has the highest viscosity

According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.

Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.

Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.

After honey, Oil is more viscous followed by milk, and then water.

Therefore, the correct option for this question is D.

Explanation:

It cannot return the the state it was in before or have the same composition it had before.

Density of a liquid determines how it will layer (heaviest to lightest). If the liquid is least dense it will float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.

b) Atoms are not subatomic particles but are rather made of subatomic particles.

c) Electrons are subatomic particles with a negative charge that are located outside of the nucleus.

d) Protons are subatomic particles that are located in the nucleus and have a positive charge.

The reaction represents a decomposition reaction because XY is broken into its constituents.

A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.

Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

Explanation:

Explanation:

getting the empirical formula

For carbon

3.01/12 = 0.2508

For oxygen

4/16 = 0.25

For Cl

17.81/35.5= 0.501

0.2508 ÷ 0.25 = 1.0032

0.25 ÷ 0.25 = 1

0.501 ÷ 0.25 = 2.004

Empirical formula of the compound = CCl20

Molar mass = (1×12) + (2×35.5) + (1×16)

= 12 + 71 + 16

= 99g/mol

percentage composition= 24.81/99 × 100

= 25.06%

A 24.81-g sample of a gaseous compound containing only carbon, oxygen, and chlorine is determined to contain 3.01 g C, 4.00 g O, and 17.81 g Cl. the compound's percent composition is  25.06%.

The impure form of carbon is Amorphous which is used for the manufacture of car batteries and dry cells, ink and paints; So the majority element of carbon is present in charcoal, so these are used as fuel.

Graphite is derivative form of carbon used as a lubricant in heavy industrial machinery, making pencil leads, these carbon are used in the production of steel.

The empirical formula, For carbon 3.01/12 = 0.2508

For oxygen 4/16 = 0.25, For Cl 17.81/35.5= 0.501, 0.2508 ÷ 0.25 = 1.0032

0.25 ÷ 0.25 = 1

0.501 ÷ 0.25 = 2.004

Empirical formula of the compound = CCl20

Then the Molar mass = (1×12) + (2×35.5) + (1×16)

= 12 + 71 + 16

= 99g/mol

percentage composition= 24.81/99 × 100

= 25.06%

Using the solubility product of the saturated solution, the mass of BaF2 dissolved is 0.083 g.

The equation of the reaction is obtained from;

BaF2(s) ⇄ Ba^+(aq) + F^-(aq)

The concentration of the substance can be obtained from the Ksp as follows;

Ksp = [Ba^2+] [2F^-]^2

Ksp = 4x^3

x = ∛Ksp/4

x = ∛ 1.00 x 10-6/4

x = 6.3  x 10^-3 M

Given that;

mass/molar mass = concentration x  volume

molar mass  = 175 g/mol

concentration  = 6.3  x 10^-3 M

volume = 75.0 ml or 0.075 L

Mass = ?

Mass  = concentration x  volume x molar mass

Mass  = 6.3  x 10^-3 M x  0.075 L x   175 g/mol

Mass = 0.083 g
