4 hydrogen atoms and 2 oxygen atoms.

<h3>What is stated by the law of conservation of matter?</h3>


The law of conservation of matter states that the amount of matter in the solution remains constant, even when the substance has a change in the format.

The amounts on the equation are given as follows:

  • 4 hydrogen atoms.
  • 2 oxygen atoms in the reactants.

The law of conservation of matter states that the amounts remain constant, hence the amounts of the solution are given as follows:

A scientist begins with 50 milligrams of a radioactive substance that decays exponentially. After 40 hours, 25 mg of the substan
saveliy_v [14]

Based on the information given, the number of milligrams that will remain after 59 hours will be 13.125 milligrams.

Since after 40 hours, 25 mg of the substance has been removed, therefore, the rate per hour will be:

= 25/40 = 0.625.

The amount that will be removed in 59 hours will be:

= 59 × 0.625 = 36.875

The number of milligrams that will remain will be:

= 50 - 36.875 = 13.125 milligrams
