Answer:
Soaps behave differently in hard water than soft and it’s not good behavior. Soaps in soft water are able to function as a cleaning agent whereas soaps in hard water are not. The same amount of soap in soft water will form more suds than it will in hard water. This is because hardness minerals react and combine with soap.

Explanation:
Answer:
the two spectator ions are; K(+) and NO3(-)
Explanation:
First off, let's write out the balanced chemical equation for the reaction;
3K2CO3(aq) +2Fe(NO3)3(aq) ----> 6KNO3(aq) + Fe2(CO3)3(s)
In order to identify which ions are spectators, we have to break the equation down to an ionic equation. This is done by splitting all aqueous compounds into ions while leaving the solids, liquids as they are.
We have;
K(+) + CO3(2-) + Fe(3+) + NO3(-) ---> K(+) + NO3(-) + Fe2(CO3)3(s)
Spectators ions are pretty much those ions that do not undergo a change in the reaction. Spectator ions always have the same number of moles and charge in both sides of the reaction.
Upon observing the ionic equation, we can tell that the two spectator ions are; K(+) and NO3(-)
25 sugar because the mass should be equal on both sides
Something created for using science for use by society. Hence, option A is correct.
<h3>What is science?</h3>
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.
Technology is the use of science to provide human problem. It can be in the form of a machine, tool or equipment. As long as it involves applying a scientific process, it's technology.
Example of technology is a computer. It's used to store and process data in a faster way. Old technology also included Hammer, Saw, Grinding Machines etc.
Hence, option A is correct.
