Answer:

1.35×10¹² μg

Explanation:

Mass (Kg) = 1350 Kg

Mass (μg) =?

Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:

1 Kg = 1×10⁹ μg

Therefore,

1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg

1350 Kg = 1.35×10¹² μg

Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.

Answer:

To convert 1350 kilograms to micrograms, we need to multiply by a conversion factor that takes us from kilograms to micrograms.

1 kilogram = 1,000,000,000 micrograms (by definition)

So,

1350 kilograms = 1350 x 1,000,000,000 micrograms

= 1.35 x 10^12 micrograms (in scientific notation)

Therefore, the mass of an adult rhino is 1.35 x 10^12 micrograms.

Answer:

Group 1 metals or the alkali metals

Explanation:

The group 1 elements are all metals except for hydrogen, the first element in the group. Group 1 metals have one valence electron in their outermost shell. The metallic character increases as one goes down the group.

The metallic character of an element is determined by how readily it loses electrons. Elements that lose electrons most easily have the greatest metallic character. Group 1 metals have the greatest metallic character due to the ease with which they donate or lose their one valence electron. As the atomic radius increases on going down the group, their metallic character increases. Also, due to screening effect of the inner electrons on the valence electron from the positive nuclear charge of the nucleus, metallic property increases on going down the group.

This problem is providing the energy of a photon of light as 2.95 × 10⁻¹⁷ J and it is required to calculate its frequency, according to the electromagnetic spectrum theory. At the end, the answer turns out to be 4.52x10¹⁶ Hz according to the following:

In chemistry, we use the electromagnetic spectrum in order to know how the wavelength, frequency and energy of particles are related to each other. In this particular case, we have a photon and the frequency can be calculated with the following arrangement:

\(E=h\nu\\\\\nu=\frac{E}{h}\)

Whereas E is the energy, h the Planck's constant and ν the frequency. Thus, we plug in these first two to obtain:

\(\nu=\frac{2.95x10^{-17}J}{6.626x10^{-34}J*s}\\\\\nu=4.45x10^{16}s^{-1}=4.45x10^{16}Hz\)

Wegener's theory was primarily rejected since he offered no explanation for how the continents might move.

Explanation:

The theory also went against many ideas widely accepted in the community.

a. Q value of 7-Li(p,n) reaction

The Q value of a nuclear reaction is the energy released during the reaction. It can be calculated using the formula:

Q = (Mi - Mf)c² where Mi is the initial mass, Mf is the final mass, and c is the speed of light.

7Li(p,n) reaction is given as:

7Li + p → n + 4

HeInitial Mass = 7.016003 amu + 1.007825 amu = 8.023828 amu

Final Mass = 1.008665 amu + 4.002603 amu = 5.011268 amu

Q = (Mi - Mf)c²

Q = [(7.016003 + 1.007825) - (1.008665 + 4.002603)] x (931.5 MeV/c²)Q = 4.02 MeV

Therefore, the Q value of 7-Li(p,n) reaction is 4.02 MeV.

b. Threshold energy of 7-Li(p,n) reactionThreshold energy is the minimum energy required for a nuclear reaction to occur. It is given as:

E(threshold) = (Mf - Mi - mn)c²/2Miwhere Mi is the initial mass, Mf is the final mass, mn is the mass of a neutron, and c is the speed of light.The mass difference between the final and initial products is

(Mf - Mi - mn) = (5.011268 - 7.016003 - 1.008665) amu = - 3.0 x 10⁻³ amu

Threshold energy E(threshold) = (- 3.0 x 10⁻³ amu x (931.5 MeV/c²) / (2 x 7.016003 amu)

E(threshold) = 1.20 MeV

Therefore, the threshold energy for 7-Li(p,n) reaction is 1.20 MeV.

The Q value of 7-Li(p,n) reaction is 4.02 MeV. The threshold energy for 7-Li(p,n) reaction is 1.20 MeV.

Without knowing the specific experiment or reaction being referred to, it is difficult to provide a detailed answer.

However, in general, signs that indicate a chemical reaction occurred include a change in color, the formation of a precipitate, the evolution of gas (bubbles), and a temperature change. A temperature change could be either an exothermic (heat is produced) or endothermic (heat is absorbed) reaction, depending on the specific reaction being observed.

If steel wool is being used in the experiment, it may be observed that the steel wool is reacting with another substance. If the steel wool reacts with oxygen in the air, it may undergo a combustion reaction, creating a temperature increase, producing heat, and possibly releasing a gas. Additionally, the steel wool may change color, become charred or blackened, and appear brittle or broken down due to the reaction.

In summary, signs that indicate a chemical reaction occurred include color change, precipitate formation, gas evolution, and temperature change. When steel wool reacts with oxygen, it may undergo a combustion reaction, producing heat, changing color, and becoming brittle.

False. Chemical reactions reach equilibrium when the rates of the forward and reverse reactions become equal. This means that the amount of reactants and products present in the system remain constant over time.

While it is true that some reactions may appear to have reached equilibrium because one of the reactants is used up, this is not always the case. In some cases, the reaction may continue to occur, but at a slower rate, until equilibrium is reached. Additionally, some reactions may involve multiple reactants or products, making it more complex to determine if one reactant being used up is the sole reason for equilibrium being reached.
False. Chemical reactions generally reach equilibrium not because one of the reactants is used up, but because the rates of the forward and reverse reactions become equal. At equilibrium, the concentrations of reactants and products remain constant, but they do not necessarily become zero. The reaction continues to occur in both directions, but the net effect is zero, as the formation of products and consumption of reactants occur at the same rate. Equilibrium is a dynamic state that reflects the balance between the forward and reverse reactions.

The half life of bromine-74 is 25min. After 75 min. only o.5mg of sample is still active.

Half-life of a radioactive element is time required for the element which undergo disintegration and reduces its initial concentration to half of the concentration.

Therefore, the half-life of  the bromine-74 is 25 minute. So we calculate the number of periods.

Half-life = time / no. of periods

No. of period = Time given / \(t_{1/2}\)

No. of period = 75 / 25 = 3

The number of periods is three and in each period  half of the amount of the initial concentration of the elements will disintegrates.

So, 6mg disintegrates into 4 / 2 and then 4 / 4 and then 4 /8

4mg→ 4 / 2→ 4 / 4→ 4 / 8

The final value will be 0.5 mg.

An oxide of chromium crystallizes with the following unit cell (chromium = gray; oxygen = red)(Figure 1) --CrO3

In order to determine the formula of the oxide, we need to determine the ratio of chromium to oxygen atoms in the unit cell. From the provided unit cell, we can see that there is one chromium atom (gray) in the center of the unit cell, and four oxygen atoms (red) surrounding it. This gives us a ratio of 1:4 chromium to oxygen, which simplifies to a ratio of 1:4 or 1/5. Therefore, the formula of the oxide is CrO4.An oxide is a chemical compound that contains at least one oxygen atom and one other element. Oxides can be either inorganic or organic, depending on the element that is combined with oxygen. Inorganic oxides are compounds composed of a metal and oxygen. They can be further classified as acidic, basic or neutral depending on the oxidation state of the metal atom.
