It requires 2,500 joules to raise a certain amount of water (c = 4.186J/g°C) from 20.0°C to 65.0°C.

How does a sample of helium at 15 degree Celsius compare to a sample of helium at 215 K?

Nadusha1986 [10]

The answer is A.
215K is equivalent to -58.15 °C and temperature corresponds with the average kinetic energy.
So the 15°C has a higher energy level than 215K.

In neutron moderation, neutrons are slowed down so that:

erastovalidia [21]

B. Nuclear fission reactions are slowed down as well.

Neutron moderation is a substance which slows down neutron. In some reaction moderator is same as coolant.

This is also used to slow down nuclear fission reaction and continue chain reactions.

The collision between neutron and nuclei is more elastic and more neutrons will be slowed due to size of the neutron.

Compound A serves as a prodrug for the analgesic benzocaine. (A prodrug is a pharmacologically inactive compound that is convert

NemiM [27]

Answer:

The hydrolysis in aqueous HCl of compound A can lead to the formation of a carboxylic acid and an alcohol.

Explanation:

The picture shows the structures of compound A, benzoncaine and the possible products of the proposed reaction.

The acidic hydrolysis is the inverse of the esterification reaction. Therefore, the ester group of compund A will react to form the equivalent carboxylic acid and alcohol.

In order to form benzocaine, the hydrolysis happens in with the nitrile group.

Drag each characteristic to the correct category.

Answer/Explanation

Characteristics of Life Present in Viruses:

has a defined boundary - viruses are made up simply of genetic material surrounded by a protein capsid and sometimes a lipid membrane

Characteristics of Life Absent in Viruses:

made up of one or more cells - one of the main arguments for why viruses are not living is that they are not cellular
uses energy - this is a tricky one. They don't use or produce their own energy. However, in order to reproduce they do hijack the host cells and steal energy from them in order to reproduce
exhibits growth and development - although viruses do reproduce, the individual viral particles do not exhibit growth or development
possess internal organisation - other than the fact they ahve genetic material, the inside of a virus does not contain internal organization like a cytosol, instead conssiting of the bare minimum amount of proteins to survive
eliminates waste - since they do not have their own metabolism, they have no waste to eliminate

What is the atom inventory for the following equation after it is properly balanced? ____NaOH + ____CuCl2 Imported Asset ____NaC

faltersainse [42]

Answer:

Reactants: Na = 2, O = 2, H = 2, Cu = 1, Cl = 2;

Products: Na = 2, Cl = 2, Cu = 1, O = 2, H = 2

Explanation:

NaOH + CuCL2 —> NaCl + Cu(OH)2

The balanced equation can be achieved by doing the following:

There are 2 oxygen and 2 hydrogen atom on the right side. This is balanced by putting 2 in front of NaOH as shown below:

2NaOH + CuCL2 —> NaCl + Cu(OH)2

This makes Na to be unbalanced. Now to balance Na, put 2 in front of NaCl as illustrated below

2NaOH + CuCL2 —> 2NaCl + Cu(OH)2

Now the equation is balanced.

Reactants: Na = 2, O = 2, H = 2, Cu = 1, Cl = 2

Products: Na = 2, Cl = 2, Cu = 1, O = 2, H = 2
