what is the final volume (L) of each of the following diluted solutions? a 0.70 M HCl solution prepared from 25 mL of a 6.0 M HCl solution
The final volume of diluted solution is 214.39 mL
From the question given above, the following data were obtained:
Molarity of diluted solution (M₂) = 0.7 M
Molarity of stock solution (M₁) = 6 M
Volume of stock solution (V₁) = 25 mL
Volume of diluted solution (V₂) = ?M₁V₁ = M₂V₂
6 × 25 = 0.7 × V₂
150 = 0.7 × V₂
Divide both side by 0.7
V₂ = 150 / 0.7
V₂ = 214.39 mLTherefore, the volume of the diluted solution is 214.39 mL

p-Nitrobenzaldehyde is more reactive toward nucleophilic additions than pmethoxybenzaldehyde. Explain
The presence of electron donating methoxy group in p-methoxybenzaldehyde , makes it less reactive towards nucleophilic additions.
Nucleophilic addition reactions that involve of p-Nitrobenzaldehyde and p-methoxybenzaldehyde both occur at the C=O functional group. The electron density around the carbonyl is a key factor that controls the reactivity of each compound.
In p-Nitrobenzaldehyde, the electron withdrawing nitro group decreases the electron density around the carbonyl making it more vulnerable to nucleophilic attack.
In p-methoxybenzaldehyde, the methoxy group donates electrons by resonance towards the carbonyl thereby increasing the electron density around it so that it is less reactive towards nucleophillic addition reaction.
The nucleophilic attack on p-Nitrobenzaldehyde leads to more resonance structures than nucleophilic attack on p-methoxybenzaldehyde.

A reaction between solid sodium hydroxide and gaseous carbon dioxide produced solid sodium carbonate and liquid water. Write out a balanced equation for this reaction.
Balanced:
2NaOH + CO2 → Na₂CO₃ + H₂O
Explanation:
To balance an equation, the amount of atoms on each side must be equal.
Atom Count on Reactant Side:
Na = 1O = 3H = 1C = 1Atom Count On Product Side:
Na = 2C = 1O = 4H = 2As you see, to simply balance the equation, put the 2 in order for the atom count on the reactant side to be equal to the product side. The 2 will add one more of each atom so that its the same as the product side.

A balloon is partially inflated with 6.00 L of hydrogen at sea level, where the atmospheric pressure is 1.00 atm. The balloon ascends to an altitude of 1500 m, where the pressure is 0.80 atm. What is the volume of the balloon at the higher altitude if the temperature of the hydrogen doesn’t change during the ascend?
Considering the Boyle's law, the volume of the balloon at the higher altitude is 7.5 L.
The gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature and moles.
Boyle's law is one of the gas laws that states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. In other words, if the pressure increases, the volume decreases; while if the pressure decreases, the volume increases.
Boyle's law is expressed mathematically as:
P× V = k
In this law then two variables are related: pressure and volume, so it is assumed that the temperature of the gas and the number of molecules of the gas are constant.
Studying an initial state 1 and a final state 2 is fulfilled:
P1× V1= P2× V2
In this case, you know:
P1= 1 atmV1= 6 LP2= 0.80 atmV2= ?Replacing:
1 atm× 6 L= 0.80 atm× V2
Solving:
[tex]V2=\frac{1 atm x 6 L}{0.80 atm}[/tex]
V2= 7.5 L
Finally, the volume of the balloon at the higher altitude is 7.5 L.

Which statement best describes the effect of radioactive decay on a nucleus?
When radioactive decay occurs, the original nucleus splits into daughter nuclei and the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
Unstable nuclei often undergo radioactive decay. In a radioactive decay, the unstable nucleus is broken up into other nuclei. Usually, the nuclei formed during radioactive decay are smaller in mass compared to the original nucleus.
Also, the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
The effect is that the nucleus changes into the nucleus of one or more other elements. These daughter nuclei have a lower mass and are more stable (lower in energy) than the parent nucleus.

What is the order of bases of the RNA molecule that is built from this DNA?
The genetic makeup of the majority of these organisms is either RNA or DNA. For instance, some viruses' genetic material may be RNA whereas others' genetic material may be DNA. RNA is present in the Human Immunodeficiency Virus (HIV), which after adhering to the host cell, transforms into DNA.
DNA is a collection of molecules that is in charge of transporting and passing genetic information from parents to children. A ribonucleic acid called RNA aids in the body's production of proteins. In the human body, new cells are created as a result of this nucleic acid.
Instead of thymine, uracil is present in RNA. All other bases are same as DNA like adenine, guanine and cytosine. The order of bases in RNA is:
