Write the equation for the reaction described: A solid metal oxide, Ag2O, and hydrogen are the products of the reaction between
Harlamova29_29 [7]

Answer:

2Ag + H2O -----> Ag2O + 2H

Explanation:

2Ag + H2O -----> Ag2O + 2H is the equation of the reaction between metal and steam. Silver reacts with water (steam) forming silver oxide and hydrogen gas. When the metals react with steam it produces the solid metal oxide and hydrogen gas. On the surface o metals, a protective layer of aluminium oxide is formed that keeps water away from the metal so we can say that silver oxide and hydrogen are formed from the reaction of silver metal and steam.

Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The ne
lianna [129]

The net force is the sum of all of the forces that cancelled out to zero. Hence, option D is correct.

<h3>What is force?</h3>

The pushes or pulls on an object with mass causes it to change its velocity.

The net force is the vector sum of all forces acting on an object. Force is a vector quantity.

Two forces of equal magnitude when acting on an object in opposite directions will cancel out each other.

As a result net force is equal to 0. The word net here shows the total force acting on the object.

Hence, option D is correct.
