Answer:
A compound
Explanation:
The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.
- An element is a distinct substance that cannot be split up into simpler substances.
- Compound are substances composed of two or more kinds of atoms joined together in a definite grouping.
- The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up.
- So, the water when broken down to elements is a compound.
The atomic number of oxygen is 8, because oxygen has eight protons in the nucleus.
Answer:
0.16 J/g℃
Explanation:
We have the following data:
heat = 1,200 J
mass of metal = m = 150 g
change in temperature = ΔT = 50.0℃
The heat absorbed is calculated by using the following equation:
heat = m x Cp x ΔT
So, we introduce the data in the equation to calculate the specific heat of the metal (Cp), as follows:
Cp = heat/(m x ΔT) = (1,200 J)/(150 g x 50.0℃) = 0.16 J/g℃
Answer:
Aldehydes derive their name from the dehydration of alcohols. Aldehydes contain the carbonyl group bonded to at least one hydrogen atom. Ketones contain the carbonyl group bonded to two carbon atoms. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O
