group of adjacent nucleic acids are a. phosphodiester bond b. peptide bonds c. lnoic bond d. covalent bonds​

Answer:

a. True

Explanation:

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.

Regards!

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:

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.

The molarity is an important method to calculate the concentration of a solution. The molarity of calcium chloride of 16.4 g in 750.0 mL of solution is 0.196 mol L⁻¹.

The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is mainly employed in calculating the molarity of a binary solution. It is represented as 'M' and unit is mol L⁻¹.

The equation used to calculate the molarity is given as:

Molarity = Number of moles of the solute / Volume of the solution in litres

Molar mass of CaCl₂ = 110.98 g/mol

Given mass = 16.4 g

Number of moles = 16.4 / 110.98 = 0.147

750.0 mL = 0.75 L

Molarity = 0.147 / 0.75 = 0.196 mol L⁻¹

Thus the molarity is 0.196 mol L⁻¹.

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%
