When sugar is dissolved in water the resulting solution is classified as a?
A mixture in which a substance has fully dissolved in water is called a solution and the substance is said to be soluble. An example of this type of mixture is sugar in water. Here the sugar dissolves fully to give a clear solution.
Which substance can be broken down by chemical means?
Gold, silver, and oxygen are examples of elements. Compounds are pure substances formed by the combination of elements; they can be decomposed by ordinary chemical means. Baking soda is a compound; it contains the elements sodium, hydrogen, carbon, and oxygen, and it decomposes on heating.
Can antimony be broken down by chemical means?
The substance that can not be broken down by chemical means is antimony.
What two substances Cannot be broken down by chemical changes?
Hover for more information. Potassium can’t be broken down by chemical change because it’s an element, which is the simplest form of matter. Sulfuric acid, ammonia and water are all compounds composed of elements. Compounds can be broken down into simpler compounds or elements by a chemical reaction.
Can Cuo be broken down by chemical change?
Answer Expert Verified. C and Cu cannot be broken down by chemical change.
Can Magnesium be broken down by a chemical change?
Which substance can be decomposed by a chemical change? Reason: when it said a substance, think of the matter chart. Substances can be broken down to a compounds or elements. Beryllium, Boron, and Magnesium are elements and Methanol is a compound which can be chemically change.
How can you identify a chemical reaction?
How can I tell if a chemical reaction is occurring? A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change.
How do you balance equations with charges?
Steps To Balance Ionic Equations
- Write the net ionic equation for the unbalanced reaction.
- Separate the net ionic equation into the two half-reactions.
- For one of the half-reactions, balance the atoms except for O and H.
- Repeat this with the other half-reaction.
- Add H2O to balance the O atoms.
- Balance charge.
How do you write a balanced half reaction?
Guidelines for Balancing Redox Equations:
- Determine the oxidation states of each species.
- Write each half reaction and for each:
- Balance the number of electrons transferred for each half reaction using the appropriate factor so that the electrons cancel.
- Add the two half-reactions together and simplify if necessary.
