What is the purpose of a catalyst?
Answer:
option c
Explanation:
as catalyst increases the reaction while activation energy is inversely proportional to rate of reaction, so option c is correct
The purpose of a catalyst to lower the activation energy of a reaction.
What is catalyst?A type of chemical that, without becoming consumed by the process, speeding a chemical reaction or reduce the temperature as well as the pressure required to initiate one. The addition of a catalyst to speed up a reaction is known as catalysis.
What is activation energy?The bare minimum additional energy needed by a reactive molecule to transform into a product is considered as activation energy.
The purpose of a catalyst is to lower the activation energy of a reaction.
Therefore, the correct answer will be an option (C).
To know more about catalyst and activation energy.

For each type of fuel shown in the table above (H2, CH4, O2), how much energy should
be added to the system in order to break the bond between the atoms forming the
molecule of the fuel?
Answer:
Explanation:
Chapter 4: Energy from Combustion The primary means of generating energy for human
endeavors is the combustion of fuels.
Coal - burned in power plants
Gasoline - burned in automobiles
Natural gas - heating
Heating oil – heating
.Propane, charcoal, wood, candles, …
Combustion (burning in air) releases the chemical energy,stored in the chemical bonds of the fuels.

Describe an every day example of an object that has energy of motion and object that has stored energy
Answer:
Humans
Explanation:
Humans have energy of motion and store energy.
Every object will have any form of energy. For instance, when we are walking we gains a kinetic energy. We use electronic devices where electrical energy is stored and can be converted to mechanical energy to activate any motors.
What is energy transformation?Energy can neither be created nor be destroyed. However it can be transformed to any other forms. Thus, the total energy will conserved always.
We have a lot of example for energy transformation and storage. The energy form stored by virtue of the position of an object is called potential energy. Whereas, when the object starts moving potential energy converts to kinetic energy.
Thus, thermal vibrations of particles, our every day activities all are associated with a kinetic energy. Kinetic energy of each body depends on the mass and velocity of the body. The more the mass and velocity more will be the kinetic energy.

At certain times of year , the oceans get warmer. Which part of the water cycle is directly affected by the warming of the ocean water?
What do scientists think is responsible for this dramatic change in height? Cite evidence from the text to support your answer.
Answer:
Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

How many moles are in 6.777 x 1023 atoms of CO2. Watch your significant figures. Question 2 options: 1 atoms CO2 1.125 moles CO2 1.13 moles 1.13 atoms CO2
Answer:
1.13moles
Explanation:
Given parameters:
Number of atoms = 6.777 x 10²³ atoms
Unknown:
Number of moles = ?
Solution:
A mole of a substance contains the avogadro's number of particles
6.02 x 10²³ particles = 1 mole
6.777 x 10²³ atoms will contain [tex]\frac{ 6.777 x 10^{23} }{6.02 x 10^{23} }[/tex] = 1.13moles

Newton's first law is demonstrated in what station?
Answer:
hope this helps!
Explanation:
This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.
