Answer:
1) A chemical reaction is shown.
SnO2 + H2 → Sn + H2O
What is true about this chemical reaction?
B.
It is unbalanced because the mass of the reactants (number of atoms) is greater than the mass of the products (number of atoms).
2) Read the information about an experiment.
Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.
Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?
A.
The steel wool should be burned inside of a sealed jar or other closed system.

Answer:
A transformation or sequence of transformations that can be performed on polygon ABCDE to show that it is congruent to polygon MNOPQ is a:
Reflect across the y-axis
Explanation:
please, see the attached graph.
The polygon ABCDE is on the right side, first (I) quadrant.
The polygon MNOPQ is on the left side, second (ll) quadrant.
We can see that the polygon MNOPQ is a reflection of the polygon ABCDE across the y-axis ( only the abscissas change their signs from positive to negative).
I believe what you are looking for is Chemotaxis.
