Answer: More than one atom of the same type chemically joined together
Explanation:
An atom is the smallest unit of any matter which may or may not have independent existence. Example: Argon (Ar) is an element which exist as Ar atom only.
Molecule is the smallest unit of any matter which always have independent existence. For example: Hydrogen (H) is an element which can exist in nature as molecule only.
Atoms of different elements chemically joined together is called as a compound. Example: is a compound formed by chemical combination of hydrogen (H) and oxygen (O) atom.
Answer:
MCO3 is BaCO3
The mass of CO2 produced is 0.28g of CO2
Explanation:
The first step in solving the question is to put down the balanced reaction equations as shown in the image attached. Secondly, we obtain the relative number of moles acid and base as mentioned in the question. The balanced neutralization reaction equation is used to obtain the number of moles of excess acid involved in the neutralization reaction.
This is then subtracted from the total number of moles acid to give the number of moles of acid that reacted with MCO3. From here, the molar mass of MCO3 and identity of M can be found. Hence the mass of CO2 produced is calculated as shown.
