Question

I. Answer in one word or one sentence:
4. Name the symbol that shows the direction of chemical reaction.
5. What is never changed in a formula to balance an equation?​

Answer 1

Answer:

1) The Chemical Reaction Arrow

2) When you balance an equation you can only change the coefficients (the numbers in front of molecules or atoms). Coefficients are the numbers in front of the molecule. ... These cannot be changed when balancing chemical equations! Subscripts are the smaller numbers found after atoms.

Answer 2

Answer:

4. The Chemical Reaction Arrow

The chemical reaction arrow is one straight arrow pointing from reactant(s) to product(s) and by-products, sometimes along with side products. A → B. It is the most widely used arrow. The single arrow emphasizes one direction of chemical change (from A to B).

5. When you balance an equation you can only change the coefficients (the numbers in front of molecules or atoms). Coefficients are the numbers in front of the molecule. ... These cannot be changed when balancing chemical equations! Subscripts are the smaller numbers found after atoms.
