I would say D. Hope I helped, sorry if I didn't. :)
Answer:
Compounds can be broken down into simpler substances by chemical means, but elements cannot. break a compound into simpler substances; oxygen and hydrogen that water contains.
But where is the following?
1.A two face mixture is a type of mixture in which the components of the mixture are in different states of matter. A good example of a two face mixture is carbonated soft drink. Carbonated soft drink is a mixture of carbon dioxide [which is a gas] and water [which is a liquid]. Another example of a two face mixture is the the mixture of iodine and sodium solution.
2. To separate the mixture of iodine and sodium solution the best separation method to use is sublimation.
Sublimation process is used to separate mixtures in which one of the component of the mixture can translate from the solid state to the gaseous state without passing through the liquid state. An example of a solid which can sublime is iodine.
The sublimation process involves heating the mixture. On heating, the sublime solid will turn to vapour and escape from the mixture leaving behind the other component. The sublime component will be regained when it cools down.
Answer:
A. 2
Explanation:
A particle of water is made up of two hydrogen atoms and one oxygen atom. However, the question asked for how many types of atoms there are, so the answer is 2.
Explanation:
A basic solution is an aqueous solution containing more OH-ions than H+ions. In other words, it is an aqueous solution with a pH greater than 7. ... Examples of common basic solutions include soap or detergent dissolved in water or solutions of sodium hydroxide, potassium hydroxide, or sodium carbonate.
