a) C6H12O6 (aq)
b) CH3COOH (aq)
c) HClO4 (aq)
d) CH3OH (aq)

Answers

Answer 1

Answer:

Final answer:

The solution with the highest pH is KOH, because it's a strong base. The most conductive solution would be HClO4, because it's a strong acid and dissociates into ions which are responsible for conducting electricity.

Explanation:

The solution that has the highest pH is b) 1.00 mol L KOH (aq). In the pH scale, lower values (0-6) represent acids, and higher values (8-14) represent bases. As KOH is a strong base, it dissociates completely in water to form K+ and OH- ions, thereby increasing the pH of the solution.

On the other hand, HNO3 is a strong acid and would have a low pH. NaCL and CaCL2 are salts and make neutral solutions, resulting in a pH of around 7.

The most conductive solution at equal concentrations would be c) HClO4(aq). Ionic compounds are good conductors of electricity in a solution since they dissociate into ions. HClO4 is a strong acid and would conduct electricity better than the others. The conductivity is due to the presence of ions which carry the current.

Answer 2

Answer:

Final answer:

A 1.00 M solution of KOH (aq) would have the highest pH because it is a strong base. A 1.00 M solution of HClO4 (aq) would be the most conductive as it is a strong, fully ionizing acid that produces a high number of ions.

Explanation:

In terms of pH, a solution of 1.00 M KOH (aq) would have the highest pH. The reason is that KOH is a strong base and it completely dissociates in water to form K+ and OH- ions, the latter of which increase the pH of the solution. HNO3, on the other hand, is a strong acid and would result in a low pH. NaCl and CaCl2 are salts and would result in neutral or slightly acidic or basic solutions, depending on the corresponding acidity or basicity of their constituent ions.

Regarding the conductivity, a 1.00 M solution of HClO4 (aq) would be the most conductive. Conductivity relies on the number of ions present in the solution that are capable of carrying current. HClO4 is a strong, fully ionizing acid producing a high number of ions in the solution. The other solutions either are weak acids like CH3COOH, which ionize only partially, or contain compounds like C6H12O6 and CH3OH that don't ionize at all.

b. silver
c. oxygen
d. copper

Answers

Iron, Silver and Copper are all metal. Only Oxygen in this specific choices is not metal. Oxygen is known to be the 3rd most abundant element in the Universe but the 1st most abundant element on earth by mass. And we all know that Oxygen is a very essential part in our daily living in this world, actually not only humans who need Oxygen but also some creatures like animals. Oxygen is represented as O in the periodic table and its atomic number is 8.

Converting carbon to nitrogen by increasing the number of protons from 6 to 7 and decreasing the number of neutrons from 8 to 7 is an example of what type of decay?

Answers

Answer: The given decay process is beta decay.

Explanation:

Beta-decay is defined as the decay process in which a neutron gets converted into a proton and an electron releasing a beta-particle. The beta particle released carries a charge of -1 units and has a mass of 0 units.

$_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta$

The chemical reaction for converting carbon nucleus to nitrogen nucleus, the equation follows:

$_6^(14)\textrm{C}\rightarrow _7^(14)\textrm{N}+_(-1)^0\beta$

Thus, the given decay process is beta decay.

this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton
