Answer:
false
Explanation
The chemical bonds were broken when creating the compound MgO.
The statement that is an alloy is just another word for a chemical compound of fixed composition that is made of two or more metals is false.
An alloy refers to the mixture of the elements in which the parent element is the metal. An alloy is produced by the amalgamation of any element, that is, metal or non-metal to better the feature of the parent metal. The whole components in the alloy are combined to produce a mixture of fixed composition, but not a chemical compound, and it is not essential that the elements involved are metals. Thus, the mentioned statement is false.
The name given to an ion that has lost electrons is cation. Details about cations can be found below.
<h3>What is a cation?</h3>
A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.
Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.
A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.
Therefore, it can be said that the name given to an ion that has lost electrons is cation.

Answer:
It would take 13 minutes.
Explanation:
The temperature decreases at a linear rate, meaning that we can describe the process by using the following formula:
Where T₂ is the final temperature, T₀ is the initial temperature; and t is the elapsed time in minutes.
We input the data given by the problem:
- 0 °C = 26 °C - 2°C/min * t
And solve for t:
