D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature  increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.

Answer:  <span>D. all of the above

All of these effect the rate, as a catalyst would speed it up, and also temperature and concentration. </span>

An analytical chemist has determined by measurements that there are 96.5 moles of carbon in a sample of acetic acid. how many mo
Nadya [2.5K]
The formula of acetic acid is CH3COOH => C2H4O2.

So, the acetic acid has the same number of atoms of carbon (C) than of oxygen (O).

Therefore, the sample that contains 96.5 moles of carbon, will contain also 96.5 moles of O.

Answer: 96.5 moles of oxygen.

The relationships among which variable quantities are expressed by the ideal gas law equation?
Eva8 [605]

<u><em>The  variable quantities are expressed by the ideal gas law equation are; </em></u>

<u><em>pressure, volume, temperature, number of moles</em></u>

<u><em /></u>

This question is simply based on defining the ideal gas law.

  • Now, A gas is considered to ideal if its particles are so far from each other in such a manner that they don't exhibit any forces of attraction between themselves. Now, in real life this is not possible but under high temperatures and pressure, we can have something close to it and that's why ideal gas laws are very important.

  • This law states that states that the pressure, temperature, number of moles and volume of a gas are related to each other by the formula;

PV = nRT

Where;

P is pressure

V is volume

n is number of moles

T is temperature

R is ideal gas constant (This is fixed and not variable)

The  variable quantities are expressed by the ideal gas law equation are;

<em>pressure, volume, temperature, number of moles</em>

Q 1 : why are cylinders of oxygen used in hospitals?
svetlana [45]

Answer:

A)provide a basis for virtually all modern anaesthetic techniques

restore tissue oxygen tension by improving oxygen availability in a wide range of conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest

aid resuscitation

provide life support for artificially ventilated patients

aid cardiovascular stability

B)Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. ... Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal.
