Use the term DNA in a sentence about proteins.

1 answer:

5 0

Deoxyribonucleic acid, or DNA is a self replicating molecule found in the cells most living things; it’s wound around proteins called histones. When the cell wants to make a protein, instructions are copied from the DNA molecule strand and then transcribed to a new molecule, called RNA.

Sorry, that’s 2 sentences, but hopefully that’s helps you out.

Calculate the standard cell emf for the reaction: ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l) Pt is used as an inert elec

Rama09 [41]

Answer: The standard EMF of the cell is 1.11 V

Explanation:

For the given chemical equation:

$ClO_3^-(aq)+3Cu(s)+6H^+(aq.)\rightarrow Cl^-(aq.)+3Cu^{2+}(aq.)+3H_2O(l)$

The half reaction follows:

Oxidation half reaction: $Cu(s)\rightarrow Cu^{2+}+2e^-;E^o_{Cu^{2+}/Cu}=0.34V$ ( × 3)

Reduction half reaction: $ClO_3^-(aq.)+6H^+(aq.)+6e^-\rightarrow Cl^-(aq.)+3H_2O(l);E^o=1.45V$

To calculate the $E^o_{cell}$ of the reaction, we use the equation:

$E^o_{cell}=E^o_{cathode}-E^o_{anode}$

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Calculating the $E^o_{cell}$ using above equation, we get:

$E^o_{cell}=1.45-0.34=1.11V$

Hence, the standard EMF of the cell is 1.11 V

What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to th

Novay_Z [31]

Answer:

Equal

Explanation:

Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.

In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

Why is this considered a theory instead of a hypothesis or a law?

UNO [17]

Answer:

This is considered a hypothesis because it hasn't been confirmed. It is just a guess.

Explanation:

A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. Law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. However, Newton's law doesn't explain what gravity is, or how it works.
