Which is more reactive oxygen or hydrogen? explain why?
mash [69]

Answer:

Explanation:

Which is more reactive hydrogen or oxygen?

Hydrogen is not particularly reactive. For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. ... It is combustible because oxygen wants electrons and takes them from hydrogen to form water.

If a lab requires each a lab group (3 students) to have 25 ml of a solution and it takes 15 grams of AgNO₃ cuprous nitrate, to m
pochemuha

Answer:

0.375 grams are needed to make 25 mL solution.

Explanation:

Mass of AgNO_3 cuprous nitrate required to make 1 l of solution = 15 g.

1 L = 1000 mL

Mass of AgNO_3 cuprous nitrate required to make 1000 mL of solution = 15 g

Mass of AgNO_3 cuprous nitrate required to make 1 mL of solution:

=\frac{15}{1000} g

Mass of AgNO_3 cuprous nitrate required to make 25 mL of solution:

=\frac{15}{1000} \times 25 g=0.375 g

0.375 grams are needed to make 25 mL solution.

In the chemical reaction below, calcium metal and water react to form calcium hydroxide and hydrogen gas. calcium metal + water
7nadin3 [17]

D. the total mass of the products will be equal to the original mass of the reactants.

Explanation:

                  Ca + 2H₂O → Ca(OH)₂ + H₂

From this chemical reaction, one can conclude that when the reaction reaches completion, the total mass of the products will be equal to the original mass of the reactants. This is in compliance with the law of conservation of mass.

  • The law of conservation of mass states that matter is the mass of products in a chemical reaction is the same as mass of the reactants.
  • This implies that the mass of the products in a given reaction is the same as that of the reactants.
  • No mass is lost in the process of a chemical change.
