What is the pH of the solution if the molarity is 0.065M[H+]

Answers

The pH of a solution that has a hydrogen ion concentration [H+] of molarity 0.065M is 1.19.

How to calculate pH?

The pH of a solution refers to the power of hydrogen in the solution i.e. the degree of acidity or alkalinity of the solution.

The pH of a solution with known concentration can be calculated using the following formula:

pH = - log [H+]

According to this question, a solution has a molarity of 0.065M. The pH is as follows:

pH = - log [0.065]

pH = 1.19

Therefore, the pH of a solution that has a hydrogen ion concentration [H+] of molarity 0.065M is 1.19.

A student built a model of DNA to show its helical structure in an attempt to display their knowledge of the chemical properties of the 3D structure. In fact, the teacher asked the entire class to create similar models. However, the teacher asks the students to incorporate a biological explanation for how each DNA molecule uniquely codes for different traits. Which component should be incorporated in the student models in order to meet the teacher's expectation for illustrating DNA's ability to code for unique traits? A) The DNA models should have different A:T, C:G ratios. B) The DNA models should have unique nucleotide sequences. C) The DNA models should have different angles of curvature for the helical strands. D) The DNA molecules should have alternating ribose and deoxyribose as the sugars in the backbone.

Answers

The DNA sequence determines the different traits, therefore, the student's DNA models should have unique nucleotide sequences.

What determines how each DNA molecule uniquely codes for different traits?

The different traits which are produced from the DNA molecule is dependent on the sequence of nucleotides in the DNA molecule.

The unique sequence of nucleotides are known as genes.

Therefore, the student's DNA models should have unique nucleotide sequences.

Describe how rate relationships and activation energy are important in chemical reactions.

Answers

Answer:

The higher the activation energy, the slower the chemical reaction will be.

Explanation:

your welcome

Answer:

The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.

Explanation: Each and every chemical reaction require some amount of activation energy to begin. The activation energy enables the reactants to move and overcome forces of repulsion. The subsequent collisions between atoms facilitates the breaking of existing bonds and the formation of new ones.

The fuel used to power the booster rockets on space shuttles is a mixture of aluminum metal and ammonium perchlorate. the following balanced equation represents the reaction.. 3al 3nh4clo4 → al2o3 alcl3 3no 6h2o how many moles of water are produced from 373 mol al?

Answers

The moles of water that are produced from 373 moles of ammonia present in any chemical reaction is 746 moles.

What is the stoichiometry?

Stoichiometry of the reaction gives idea about the amount of entities present in any chemical reaction before and after the reaction.

Given chemical reaction is:

3Al + 3NH₄ClO₄ → Al₂O₃ + AlCl₃ + 3NO + 6H₂O

From the stoichiometry of the reaction it is clear that:

3 moles of Al = produces 6 moles of H₂O

373 moles of Al = produces 6/3×373 = 746 moles of H₂O

Hence required moles of water is 746 moles.

Answers

Answer:

[tex] \: \boxed{ \sf \: Plutonium \: to \: Uranium \: is \: Alpha \: Decay! }[/tex]

Explanation:

Some nuclei attains more stabily by reducing their size, Alpha Decay is an example of such scenery.Nuclei having more than 210 nucleons, are so large in size hence the balancing force which prevents the repulsion between protons dominates, and due to excessive of protons lead to decay.

Consider any radioactive atom X with atomic mass A & atomic number z, when undergoes

alpha decay or radioactive emission, then the initial nucleus undergoes Excited state, and while returning to ground state it emits Gamma Radiation.

[tex]\boxed{\sf X_z^A \rightarrow Y_{z-2}^{A-4}+He_2^4+ \gamma }[/tex]

Given,

Parent nuclei X = Pu(A= 240, z=94)

Daughter nuclei Y = U(A= 236, z=92)

[tex]\sf Pu_z^A \rightarrow U_{z-2}^{A-4}+He_2^4 \\ \sf Pu_{94}^{240} \rightarrow U_{94 - 2}^{240 - 4}+He_2^4 \\ \sf Pu_{94}^{240} \rightarrow U_{92}^{236}+He_2^4 [/tex]

Hence the given fission of plutonium to uranium is Alpha Decay!

Some greenhouse gases, such as fluorocarbons (CFCs, HFCs, PFCs, etc.), are human-made. Others, such as water, methane, and carbon dioxide, are naturally produced. Which type of greenhouse gas (human-made or natural) is more difficult to control and eliminate? Which types are easier? In three to five sentences, provide evidence for your argument.

Answers

Carbondixoide gas is the type of greenhouse gas which is more difficult to control and eliminate.

Which gas is difficult to remove and reduce?

Carbon dioxide is the greenhouse gas that is emitted through human activities which can be controlled by reducing human activities which is impossible for us because large number of products are produced from which carbondioxide gas is released.

So we can conclude that carbondixoide gas is the type of greenhouse gas which is more difficult to control and eliminate.

The mechanical advantage of a screw can be increased by __________.

arranging the threads further apart
making it longer
arranging the threads closer together
turning it faster

Answers

The resistance and the effort force are used to calculate the mechanical advantage. Arranging the threads of the screw closer together will increase the mechanical advantage. Thus, option C is correct.

What is the mechanical advantage?

Mechanical advantage is the ratio of the output force to the input force. It allows easier task performance by obeying the conservation of mass.

The closer threads of the screws make the distance covered to be more, and the force applied will be multiplied which will be a mechanical advantage over threads placed far apart.

Therefore, option C. threads located closer have more mechanical advantages.
