Question 1: A change in state
Question 2: Are two terms for the same thing
Question 3:
Question 4: Heat is added to it
Question 5: Freezing point
Question 6:
Answer:
The correct answer is option (6).
Explanation:
A molecule is group of atoms of same or different kinds of element.
In carbon monoxide there is a single carbon atom and single oxygen atom. Hence, a molecule.
Compound is defined as a chemical specie which is made by the combination of different atoms.
As we can see from the chemical formula of carbon monoxide is made up of two atom of different elements that is carbon and oxygen.
A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass. They have definite set of properties.
1 mole of carbon combined with 0.5 moles of oxygen gas to give carbon monoxide gas.
CO + 2 H2 → CH3OH
<span> find # of mols in each reactants, </span>
<span>152500 g CO x 1 mol CO / 28.01g CO = 5444 mol CO </span>
<span>24500 g H2 x 1 mol H2 / 2.02 g H2 = 12129 mol H2 </span>
<span>mol ratio between CO and H2 is 1:2, which means each mol of production of CH3OH need 1 mol of CO and 2 mol of H. </span>
<span>H2 is enough to produce 6064 mols of CH3OH but there are only 5444mol of CO. </span>
<span>5444 mol CH3OH x molar mass of CH3OH / 1 mol CH3OH </span>
<span>= 174371 g = 174.4 kg</span>
A nuclear reaction changes the number of protons and or neutrons in an atom.
<h3>What do nuclear reactions change in the atom?</h3>
A nuclear reaction is a type of reaction that results in the change of the nucleus of an atom. We know that a nucleus of an atom is made up of protons and neutrons.
So we can conclude that a nuclear reaction changes the number of protons and or neutrons in an atom.
