Question

Brad and Juan conducted several tests to determine the properties of silver metal. They noted that is was white, and conducted both electricity and heat. They computed the density to be 10.49 g/cm3. Silver did not react with water but in nitric acid, gas was released. What evidence supports a chemical change in the silver? A) Silver conducts electricity. B) Silver reacts with nitric acid to produce a gas. C) The color of silver at room temperature is white. D) Silver conducted heat and as the temperature increased, became more malleable.

Answer 1

B because it should be

Step-by-step explanation:

and that is right answer??

Answer 2

The answer is B) Silver reacts with nitric acid to produce a gas.
If a substance reacts with another substance to create a different substance, it is a chemical change. Color doesn't really matter with chemical changes, neither does electrical conductivity.

Hope this helps!
