Answer:
a)
b)
Explanation:
Hello,
a) In this case, for this kinetics problem, we can consider the temperature-dependent Arrhenius equation:
In such a way, for the given temperatures and rate constant, we compute the activation energy as follows:
b) In this case, we use the previously computed activation energy in order to compute the rate constant at the asked 17°C:
Best regards.
Aluminum can be oxidized by and
<h3>What is oxidizing?</h3>
Some of the metal corrodes (or oxidizes) and forms the corresponding metal oxide on the surface as a result of a chemical reaction between the metal surface and the oxygen in the air. The corrosion products that occur in some metals, like steel, are highly apparent and loose.
According to reactivity series (The array of metals in the descending order of their reactivities is referred to as the metals' reactivity series. It is sometimes referred to as the metals in the activity series.)
Lithium and calcium ions are more reactive than aluminum ion and they are less electronegative.
Since silver and tin are more electronegative than aluminum so, they cannot oxidize aluminum.
∴ and ions can oxidize aluminum.

Answer:
thermometer
Explanation:
The most important tool to use when collecting data relating to how thermal energy affects metals would be <u>the thermometer.</u>
The thermometer is an instrument used to measure temperatures and the temperature of a body is a measure of the amount of thermal energy present in the body.
<em>In order to obtain data relating to how thermal energy affects metals, the most important variable to take note of would be the thermal energy of the metals and this can only be done by the thermometer.</em>
The answer is the most probable location of electrons in an atom
