I think the element that has been correctly defined by Antoine Lavoisier would be the element oxygen. He is famous for the discovery of the importance of the molecule oxygen in the process of combustion. He is is the one who characterized and named the element oxygen and hydrogen. Also, showing how these atoms combine in order to form a water molecule in the combustion process. He is considered as the father of modern chemistry as he helped in organizing nomenclature of the chemical compounds. He also is responsible for laying the foundations of the famous law of conservation of mass.
Answer:
The nucleus in eukaryotes and the cytoplasm in prokaryotes
Explanation:
The nucleus is the largest organ in a eukaryotic cell which is responsible for the control of the cell activities based on processing of received information and cell administration. The nucleus is therefore, known as the cell cell control center for regulating the metabolism of the cell and administers the cell and cellular information with which proteins are made
The nucleus contains nucleolus and it is the store for the chromosomes, which play an important role in genetics, related to the synthesis and replication of DNA and RNA
The functions of the nucleus are spread out through out the cytoplasm of prokaryotes.
Answer:
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
Explanation:
We are given;
The unbalanced equation;
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
We are required to balance the equation;
- We need to know that balancing of chemical equations involves putting the appropriate coefficients on reactants and products to ensure equal number of atoms of each element on both sides of the equation.
- Balancing of chemical equations is a try and error method of making sure that the law of conversation of mass in chemical equations is obeyed.
- In our case, the appropriate coefficients will be, 1, 2, 1, 1
Therefore;
The balanced equation will be;
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
