Convergent plate boundaries if I’m not mistaken
Answer:sNo, Air is not an element It's a mixture of a variety of gases.
Explanation:
That there was a positive mass located somewhere in the atom which was called the nucleus. it also showed that most of the atom was empty space
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)
