Consider the following oxidation-reduction reaction: 2fe3+(aq) + 2hg(l) + 2cl−(aq) → 2fe2+(aq) + hg2cl2(s). indicate the oxidizing agent and the reducing agent.

Answers

Answer:

The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)

Explanation:

first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.

Hg went from a charge of 0 to a charge of +1

Cl went from a charge of 0 to a charge of -1

remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.

The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules. which of the following is most likely true about mercury? it has a higher surface tension than does water. it exhibits greater capillary action than does water. it is very soluble in water.

Answers

The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules because it has a higher surface tension than does water.

What is surface tension?

Surface tension is the propoerty of the surface of liquids by which they will shrink into the minimum possible surface area.

Surface tension of the liquid mercury is greater than the surface tension of water means cohesive attraction force between the molecules of mercury is greater than water molecules.

If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K

Answers

The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

How to calculate temperature?

The temperature of a given gas can be calculated by using the ideal gas law equation:

PV = nRT

Where;

P = pressure V = volume n = number of molesR = gas law constantT = temperature

no of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol

2.35 × 1.2 = 1.08 × 0.0821 × T

2.82 = 0.088T

T = 2.82/0.088

T = 31.8K

7.25 moles of air are pumped into a car tire. At 80°C, the pressure inside the tire is 506.625
kPa. What is the volume of the tire?

Answers

For this question you need to use the ideal gas equation PV = nRT.

P is pressure, V is volume, n is number of moles, R is molar gas constant (8.31J/mol*K) and T is temperature.

The temperature must be in Kelvin for this equation, 80°C in kelvin is (80 + 273.15) = 353.15K

We also want to convert the kPa into Pa so we times by 1000 giving us 506625Pa

Since we’re looking for volume we rearrange to make V the subject giving us V = nRT/P.

Now you just plug in the values, V = 7.25 * 8.31 * 353 / 506625 which will give us 0.042m^3.

what is density/ how does density work

help help ​

Answers

Answer:

Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.

Explanation:

Answer:

The mass per unit volume of a substance is called density of that substance.

Explanation:

So, How does it works ?

For example: Density of gold is 19300kg/cubic meter. It means that if there gold having volume of a cubic meter its mass will be 19300 kg... Density of plastics are less than that of density of metals... I.e. if we take plastic having volume 2 cubic meter & gold having volume 1 cubic meter we will find mass of gold is far more compared to that of plastic.. Thus, density refers how much tightly the molecules of a substance are bonded together.
