You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

a sample of matter breaks down into two kinds of atoms. Was the original sample an element or a compound?

Answers

The original sample was an compound, as an element would simply just not break down as it’s composed by itself.

Answer:

element

Explanation:

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

The following table shows the currently accepted half-life values for four parent isotopes.

Parent Isotope Currently Accepted Half-Life Values
Uranium-238 4.5 billion years
Uranium-235 704 million years
Thorium-232 14.0 billion years
Rubidium-87 48.8 billion years
Potassium-40 1.25 billion years
Samarium-147 106 billion years

Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope?
Rubidium-87
Thorium-232
Uranium-235
Uranium-238

Answers

Answer:

The amount of substance present in a certain sample can be calculated through the equation,

A(t) = A(o)(0.5)^(t/h)

where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.

For a substance to at most 50% of the original amount, we get the half-life value.

At/Ao = 0.5 = 0.5^(4.5/h)

h = 4.5 billion.

ok the answers are simple:
