Answer:

C. Precipitation of white bismuth hydroxide.

Explanation:

When aqueous ammonia is added to a solution that has Bi3+ and CU2+ cations, what we would have as a chemical result is the precipitation of white Bismuth hydroxide.

The chemical reaction for this can be written as,

Bi3+ + 2NH3 + 3H2O ⇌ Bi(OH)3(s) + 3NH4

Explanation:

Answer:

Amount of solute decreases

Explanation:

Since during dilution, the solute dissolves on the solvent hence its amount decreases.

Answer:

The similarity is that they both follow the laws of physics.

In both cases, the motion is opposed by the medium where the object presses through the medium and forces it to part and flow around the object. This creates friction.

If an object is smooth and pointed like a bomb, the friction is minimised. If it is rough with pockets or vertical flat surfaces, the friction is maximised. A parachute presents a round hollow cup face to the flow, maximising friction. This is due to a hole in the top of the parachute.

The difference is the power source. In the vertical direction it is generated by gravity, the force created by the planet. This force is opposed not only by friction but also the difference between the density of the object and the medium surrounding it. If there is a large difference then the acceleration will be large and a high percentage of g.

For example we have a density of 1000 kg/meters cubed and air has a density of 1 Kg per meters cubed, the difference is 999, so we fall at an acceleration of 999/1000 x g. minus the effects of friction.

In the horizontal direction, gravity still opposes the movement creating friction in the vertical direction such as dragging a heavy object on the floor behind you. Force needs to be created horizontally to oppose the friction and to create an acceleration. A balance is soon reached where the acceleration stops and the object is dragged at a constant velocity.

When in direct contact, the fast-moving molecules in the radiator collide with the slow-moving molecules in the ice cube. Kinetic energy is transferred from the molecules in the radiator to the molecules in the ice cube, causing a slowdown of the radiator molecules and an acceleration of the ice molecules.

An example of a balanced chemical reaction (equation) is: D. [tex]C_3H_60 + 40_2[/tex] ----> [tex]3CO_2 + 3H_20[/tex]

In Chemistry, a chemical equation is typically used to denote or represent the chemical reaction between two or more chemical elements.

A balanced chemical equation can be defined as a chemical equation wherein the number of atoms on the reactant (left) side is equal to the number of atoms on the product (right) side.

This ultimately implies that, both the charge on each atom and sum of the masses of the chemical compounds or elements in a chemical equation are properly balanced.

Ideally, the first step in balancing a chemical equation is to count the number of atoms in the reactant and product side.

                                    [tex]C_3H_60 + 40_2[/tex] ----> [tex]3CO_2 + 3H_20[/tex]

For reactants:

For products:

Since, the number of atoms on the reactant (left) side is equal to the number of atoms on the product (right) side, this is an example of a balanced chemical reaction (equation).

Answer:

[tex]720\ \text{mL}[/tex]

Explanation:

M = Molarity of NaOH = 0.25 M = 0.25 mol/L

n = Number of moles of NaOH = 0.18 moles

Volume of solution is given by

[tex]V=\dfrac{n}{M}[/tex]

[tex]\Rightarrow V=\dfrac{0.18}{0.25}[/tex]

[tex]\Rightarrow V=0.72\ \text{L}\times 10^3=720\ \text{mL}[/tex]

The volume of NaOH in the solution is [tex]720\ \text{mL}[/tex].

Answer:

87.15%

Explanation:

To find percent yield, we can use this simple equation

[tex]\frac{Actual}{Theoretical} *100[/tex]

Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.

They give us these values, so to find the percent yield, just plug the numbers in.

[tex]\frac{30.85}{35.40} *100\\\\ =87.15[/tex]

So, the percent yield is 87.15%

An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.

Answer:

A convex lens bends light rays inward, which results in the object being perceived as larger or closer.

Explanation:

The light ray refracted from an object may look different based on how they bends light and at what angle. Convex lens bends light inwards and the refracted light appear closer and bigger whereas, a concave lens makes light ray away and smaller.

Refraction is the optical phenomenon by which a light ray bends in its direction when passing from one medium to the other. For instance light ray bends when it pass from air to water or air to glass and vice versa.

The measure of bending of light in a medium  is called refractive index of that medium. Refraction makes the object appear to be closer sometimes such as in water when light bends in direction.

When light refracts from convex lens, the bending is inwards and the object is perceived to be closer and larger. Whereas, a concave lens make the bending outwards where the object appeared to be smaller and far.

According to the molar concentration, the molarity of the initial solution before the dilution is 0.096 M.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution of values in formula M₁V₁=M₂V₂ gives M₁= 0.4×1.2/5=0.096 M.

Thus, the molarity of the initial solution before the dilution is 0.096 M.

Answer:

How do scientists determine the chemical compositions of the planets and stars? Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. ... That fingerprint often appears as the absorption of light.

Explanation:

We can conduct different spectroscopic techniques for the sample collected from stars and planets to determine their composition. Using these techniques, scientists can identify the compounds and elements present in them.

There are various spectroscopic techniques such as IR spectroscopy, UV- visible spectroscopy, mass spectroscopy etc. to determine the composition of both inorganic and organic compounds.

The IR spectroscopy uses the vibrational transitions of molecules by the absorption of IR radiation. The stretching or bending frequency of each functional groups are characteristic to them. Hence, we can determine the functional groups present in the molecules.

Similarly mass spectrum, atomic emission spectrum etc. provide valuable information about the sample under study including their mass and elemental compositions. Hence, spectral signature definitely helpful to determine the composition in stars and planets.
