Is coffee mixture or compound?
Coffee is a solution, not a compound or mixture, as it includes a solute that dissolves into a solvent. Compounds must be bonded chemically, and mixtures have visibly separate parts. Coffee can also be considered a mixture since it involves two mixed substances, but this is too vague.

Is Hot Tea a solution?
Tea is a complex mixture of compounds which are all water soluble making it a solution.
Is tea a solute?
What’s Your State?
| Type of Solution: Example | Solute | Solvent |
|---|---|---|
| Gas dissolved in liquid: carbonated water | carbon dioxide | water |
| Liquid dissolved in gas: moist air | water | air |
| Liquid dissolved in liquid: vinegar | acetic acid | water |
| Solid dissolved in liquid: sweet tea | sugar | tea |
Is honey and tea a solution?
A solution forms when the solute’s particles separate and become surrounded by the solvent particles. Tea is a good example because it is made up of a solvent (hot water), and one or more solutes (for example: sugar, honey, creamer, tea mix, cocoa, and milk).
Is orange juice a solution?
A homogeneous mixture often called as solution, orange juice is a solution without pulp, uniformly distributed throughout the mixture. Orange juice with pulp is not uniformly distributed through-out the mixture called heterogeneous mixture, often called as suspension.
What are 10 solutions examples?
Expert Answers
- coffee or tea.
- sweet tea or coffee (sugar added to solution)
- any juice.
- saltwater.
- bleach (sodium hypochlorite dissolved in water)
- dishwater (soap dissolved in water)

What is orange juice an example of?
Orange juice is a heterogeneous mixture. Shaking the mixture mixes the components of the orange juice. However, eventually the mixture will settle again into layers. Orange juice is an example of a suspension.
What are 3 examples of solutions?
Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can’t see the salt particles anymore, making this a homogeneous mixture.
How can you check that a solution is correct?
We check a solution to an equation by replacing the variable in the equation with the value of the solution. A solution should result in a true statement when simplified.
What is a system that has no solutions?
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
What is the condition of no solution?
A linear equation in two variables is an equation of the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. A system of linear equations that has no solution is called an inconsistent pair of linear equations.
How can two lines have infinitely many solutions?
Conditions for Infinite Solution The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. In other words, when the two lines are the same line, then the system should have infinite solutions.
How do you know if the system has no solution?
A system has no solutions if the lines are parallel. When solving the system, if you get a false statement (a number equal to a different number) this means there are no solutions.
