Why is the same type of nail used in all test tubes? in every experiment done to show how rusting works and in what conditions.

Answers

in test tube 1 iron nail gets both air and moisture which is required for rusting. ... in the test tube 3 iron nail is not rusted because of the calcium chloride which is moisture absorber. hence nail would not get moisture for the rusting.

Answers

Answer:

Anser is C Agl

Explanation:

Agl does not dissolve in water.

All of the following compounds are soluble in water except AgI because of very high value of lattice energy. Therefore, the correct option is option C.

The capacity of a material, the solute, to combine with a different material, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration for the solute within a saturated solution—a solution where no more of the substance can be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. The two compounds are considered to be at the point of solubility equilibrium at this time. All of the following compounds are soluble in water except AgI because of very high value of lattice energy.

Therefore, the correct option is option C.

A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature of the water rose by 4.20 Ce … lsius. If the heat capacity of the bomb plus water was 10.4 kJ/degree Celsius, calculate the molar heat of combustion of methanol

Answers

The formula for calculating the amount of energy or heat released is:

ΔH = C ΔT

where ΔH is heat of combustion, C is heat capacity, while ΔT is change in temperature

ΔH = 8.69 kJ / °C * (5.14°C)

ΔH = 44.67 kJ

Then we calculate the moles of CH3OH which has molar mass of 32.04 g/mol:

moles = 1.922 / 32.04 = 0.05999 mol

SO the molar heat of combustion is:

ΔHm = 44.67 kJ / 0.0599875 mol

ΔHm = 744.60 kJ / mol

Answers

No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol

Mr of Na2O = 23+23+16 = 62 g/mol

n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol

m = n x Mr

Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate

Answers

Answer:

Potassium is more reactive than aluminium, so no reaction takes place. But aluminium is more reactive than copper, so it replaces the copper in copper nitrate

Explanation:

More reactive metal compound + less reactive metal

-> no reaction

However

Less reactive metal compound + more reactive metal

-> more reactive metal compound + less reactive metal

This is called substitution reaction where the more reactive metal replaces the less reactive metal in the compound.

The maximum amount of a substance that can be dissolved in a solvent at a given temperature is referred to as its solubility.

Sucrose has a solubility of 320 g/100 g H2O at 70°C.

How is solubility usually measured?The equilibration of a suspension followed by an assessment of the solution composition, from which the solution concentration can be determined, is a widely accepted and accurate method for measuring solubility.The maximum amount of a substance that can be dissolved in a solvent at a given temperature is referred to as its solubility. This type of solution is known as saturated. To calculate the solubility in g/100g, divide the mass of the compound by the mass of the solvent and multiply by 100 g.The ability of a compound to dissolve in a liquid that functions as a solvent aids in the determination of the solubility test. The tests are critical because they determine the polarity of unknown compounds.

The points coincide because that's how we definedour translation3. Rotate rectangle A'B'C'D' by angle D'A'S. Segment A"D" now lies on ray PS. The rays coincide because that's how we defined our rotation.4. Dilate rectangle A"B"C"D" using center A" and scale factor AD. Segments A"D" and PS now coincide. The segments coincide because A" wasthe center of the rotation, so A" and P don't move, and since D" and S are on the same ray from A", when we dilate D" by the right scale factor, itwill stay on ray PS but be the same distance from A" as S is, so S and D' will coincide.5. Because all angles of a rectangle are right angles, segment A'B' now lies on ray PQ. This is because the rays are on the same side of PS andmake the same angle with it (If A'B' and PQ don't coincide, reflect across PS so that the rays are on the same side of PS.)6.
