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.

What is DNA?
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

What is the smallest unit found in a bar of gold. A. atom. B. Cell. C. Element. .D Nucleus PLEASE HELP
Answer:
c. element
Explanation:
Because gold is its own element, a gold bar is only made of one element.
The smallest unit found in a bar of gold is the nucleus of its atom. The core of an atom is called its nucleus which contains the nucleons protons and neutrons.
What is nucleus?An atom is composed of nucleons and electrons. The core of an atom is called its nucleus. Protons and neutrons are located inside the nucleus. They are called the nucleons.
The electrons are revolving around the nucleus through circular trajectories of fixed energies. Every elements are composed of their atoms. Atoms of different elements combine together to form compounds.

If the spring constant is 12.6N/m and a spring is stretched by 0.25m, how much force has been applied?
Answer:
3.15N
Explanation:
We use this equation:
F= k∆x
Where ∆x refers to the amount or stretch or compression and k is the spring constant.
F = force
k = spring constant
∆x = change in length of spring
To find the value of F:
F= k∆x
F= 12.6x0.25
F= 3.15N
how many moles are in 4.38 of AgNO2
Answer: 0.02 moles
Explanation:
The number of moles in 4.38 g of AgNO₂ is equal to 0.028 mol.
What is a mole?A mole can be described as a standard unit that can be utilized to calculate a given number of particles. The constituents counted are usually individually distinct but identical entities.
A mole of the substance can be used to calculate quantities of atoms, molecules, ions, or other particular particles. The quantity of matter can be described as measured by elementary entities.
The number of constituents present in one mole is equal to 6.023× 10 ²³ which is known as Avogadro’s constant.
Given, the mass of AgNO₂ = 4.38 g
The mass of one mole of AgNO₂ = 153.87 g
The number of moles of in 4.38 g of AgNO₂ = 4.38/153.87 = 0.028 mol
Therefore, the number of moles of AgNO₂ is equal to 0.028 mol.

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
Explanation:
A dry cleaning solvent (molar mass = 146.99 g/mol) is a compound containing C, H & Cl is suspected to be a cancer causing agent. When a 0.250g sample was studied by combustion analysis, it was found that 0.451g of CO2 and 0.0617g of H2O were produced. From this data determine the empirical and molecular formula of the dry cleaning agent.
Answer:
Okay so set up an equation for what's happening
_C + _H + _Cl + O2 --> _CO2 + _H2O
0.451g of CO2. Convert to moles by using the molar mass of CO2 which is 44 g/mol. Now look at the ratio between Carbon and Oxygen in CO2. It's 1C:2O You just want to find C.. so do the number of moles CO2 and multiply it by 1 since the ratio says 1 carbon atom. Now you have moles of carbon. Put this number aside for later.
Do the same thing with H2O. Convert to moles by using the molar mass of H2O which is 18 g/mol. Now look at the ratio between Hydrogen and Oxygen. It's 2H:1O You just want H.. so do the number of moles of H2O and multiply it by 2 since there's 2 hydrogen atoms. Now you have the moles of hydrogen & put this number aside for later
