The question is incomplete, the complete question is;
when two colorless solutions of ionic compounds are mixed, and the final mixture remains colorless. What type of a change does this represent? Select from the options below The information provided is insufficient for determining the type of change Physical change because the absence of color change indicates that there is no change in chemical composition of the mixture B Chemical change because the absence of color change indicates that there is a change in chemical composition of the mixture
Answer:
The information provided is insufficient for determining the type of change
Explanation:
A chemical change is one in which new substances are formed. Chemical changes are not easily reversible and they are often accompanied by evolution or absorption of heat.
A physical change does not lead to the formation of new substances. It is easily reversible.
Change in colour alone can not tell us whether a physical or chemical change has taken place. This is because colourless, miscible substances may have been formed in the process hence the final mixture remains colorless.
It is also possible that the two solutions were merely physically mixed. This is a physical change,
Therefore, the information provided is insufficient for determining the type of change.
Uh I can help you with the converting into moles, 50 grams= 2.775421, sorry if I didn’t help much :/
Examples of agroecology method use are in Burkina Faso are conservation tillage, green manures, natural fertilisers, biological predators and so on.
<h3>What is Agroecology?</h3>
Agroecology refer to an approach that use ecological processes in agricultural production systems.
The benefits of Agroecology is that it help to protect, restore and also improve agriculture and food systems when there is climate shocks and unfavorable weather conditions.
Therefore, Examples of agroecology method use are in Burkina Faso are conservation tillage, green manures, natural fertilisers, biological predators and so on.
