Answer:

1. Rubidium metal reacts very rapidly with water to form a colorless basic solution of rubidium hydroxide (RbOH) and hydrogen gas (H2).

2. Rubidium sinks because it is less dense than water. It reacts violently and immediately, with everything leaving the container. Rubidium hydroxide solution and hydrogen are formed.

Hello there!

In this case, since the dose-response method is crucial concept in toxicology as it exhibits the result of exposures to toxic chemical compounds with changes in body functions or health, this statement is a. True , as this analysis is understood by means of the relationship -the higher the dose, the more severe the response-, and of course, it is based on observed data from controlled experiments in animal, human clinical, or cell studies, in the light of the determination of the toxicity of the analyzed chemical.

Answer: The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} KClO_3=\frac{1.00g}{122.5g/mol}=0.008moles[/tex]  

[tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]  

According to stoichiometry :

2 moles of [tex]KClO_3[/tex] produce= 2 moles of [tex]KCl[/tex]

Thus 0.008 moles of [tex]KClO_3[/tex] will produce=[tex]\frac{2}{2}\times 0.008=0.008moles[/tex]  of [tex]KCl[/tex]

Theoretical yield of [tex]KCl=moles\times {\text {Molar mass}}=0.008moles\times 74.5g/mol=0.596g[/tex]

% yield = [tex]\frac{\text {Actual yield}}{\text {Theoretical yield}}\times 100=\frac{0.500g}{0.596g}\times 100\%=83.9\%[/tex]

The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%

Answer:

carbonate ion < carbon dioxide < carbon monoxide

Explanation:

Bond strength depends on the bond order of a bond. The higher the bond order, the greater the bond strength since shorter bonds are stronger than longer bonds.

The carbonate ion has a bond order of 1.33, carbon dioxide has a bond order of 2 while carbon monoxide has a bond order of 3.

Since the compound with the highest C-O  bond order has the strongest C-O bond, then carbon monoxide possesses the strongest C-O bond.

Answer: carbonate ion < carbon dioxide < carbon monoxide

Explanation: Carbon dioxide (chemical formula CO2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO2 is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. When carbon dioxide dissolves in water, it forms carbonate and mainly bicarbonate (HCO−3), which causes ocean acidification as atmospheric CO2 levels increase. Bond strength depends on the bond order of a bond. The higher the bond order, the greater the bond strength since shorter bonds are stronger than longer bonds. The carbonate ion has a bond order of 1.33, carbon dioxide has a bond order of 2 while carbon monoxide has a bond order of 3. Since the compound with the highest C-O  bond order has the strongest C-O bond, then carbon monoxide possesses the strongest C-O bond. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.

Answer:

Differences in water density affect vertical ocean currents. Denser water tends to sink, while less dense water tends to rise. Other causes of currents include tides, rain, runoff, and ocean bottom topography. Topography is the surface features of a place. Ocean topography includes slopes, ridges, valleys, and mountains! All these things are found at the bottom of the ocean, and can influence currents.

The cause-and-effect relationship between density and ocean currents is the mixing and circulation are influenced by the density differences between the various layers of the water column.

The continuous, predictable, and directional movement of seawater known as ocean currents is caused by gravity and wind.

Ocean vertical currents are influenced by variations in water density. Less dense water tends to rise, while denser water sinks. Tides, rainfall, runoff, and the topography of the ocean bottom are additional causes of currents.

Thus, the mixing and circulation are influenced by the differences in densities between the various layers of the water column, which is the cause-and-effect relationship between density and ocean currents.

Answer:

5.52 g

Explanation:

First we convert the given masses of both reactants into moles, using their respective molar masses:

Now we calculate with how many NH₃ moles would 0.056 O₂ moles react, using the stoichiometric coefficients:

As there more NH₃ moles than required, NH₃ is the excess reactant.

Then we calculate how many NH₃ moles remained without reacting:

Finally we convert NH₃ moles into grams:

Answer:

When a system is at equilibrium, the process is not spontaneous at either direction.

Explanation:

The process is not spontaneous at either direction , when a system is at equilibrium  ΔG = 0, because -

We know that a negative ΔG indicates a forward-moving phase that is random.

We already know that a positive ΔG implies a non-spontaneous phase going forward.

Thus , here ΔG = 0, so the process is not spontaneous in either direction.

Explanation:

Ne is a noble gas. It already has an octet of electrons hence, the electron affinity of neon is negative.

Br is a halogen, halogens need one electron to complete their octet. The electron affinity for bromine is negative.

Sodium is a metal that has only one electron in its outermost shell. The electron affinity of sodium is positive.

Magnesium is a metal having two electrons in its outermost shell. The electron affinity of magnesium is positive.

Chlorine is another halogen, energy is released when an electron is added to chlorine hence the electron affinity of chlorine is negative.
