Answer:
element made up of four (4) similar atoms.
Explanation:
An element is made up of one kind of atom. A compound is made up of 2 or more different kinds of atoms that are chemically together.
"High temperatures make the gas molecules move more quickly" is the one sentence among all the choices given in the question that most likely explains why this reaction is carried out at high temperature. The correct option among all the options that are given in the question is the third option or option "C".
the man made element that is in an anomalous location is Transuranium.
Bonjour,
increasing temperature.
for many solids dissolved in liquid water, the solubility increases with temperature.
Answer: Graph 3
Explanation:
Activation energy is the level of energy required by a chemical reaction for the reaction to proceed.
A higher Activation energy will translate to a lower reaction rate because less molecules will be able to achieve this required energy needed for them to react. A lower activation energy however will enable a faster reaction time because more molecules will achieve the required energy.
Higher Activation energy = Lower Reaction rate
Lower Activation energy = Higher reaction rate
This is what Graph 3 shows so it is correct.
