The color of a planet provides clues to its composition. From space, much of Earth looks blue because most of its surface is cov

ered with water. The surface of Mars is much different from that of Earth. Much of its surface is made up of iron oxide, or "rust." Which color would you expect Mars to be?

Answer:

Mars would have different variations of brown, red, and orange.

Explanation:

Since different places of Mars have different substances or have different "ages" the color will be different.

Rust is formed because iron reacts to different substances, so there might be different weather patterns around Mars, and hence different colors of the rocks, iron, etc.

Hope this helps:)

Sorry just a 4th grader :(

I think this is correct though

A neutral atom of Cl-37 has
Ostrovityanka [42]

Answer:

17 protons, 20 neutrons, and 17 electrons​.

Explanation:

A periodic table can be defined as the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.

Generally, a proper representation of the mass number and atomic number of chemical elements is key and very important in chemistry.

Furthermore, as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton).

The mass number of this neutral atom of Cl-37 is 37 and we know that the atomic number (number of protons) of chlorine is 17. Also, the atomic number of an element is equal to the number of its electrons.

A neutral atom of Cl-37 has 17 protons, 20 neutrons, and 17 electrons.

Hence, a neutral atom of Cl-37 can be identified based on its number of protons because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.

Answer:

Infectious diseases are commonly transmitted through direct person-to-person contact.

The main four pathogens are virus, bacteria, protists and fungi.

Bacteria, fungi and protists can reproduce wherever the conditions are warm, with plenty of moisture, nutrients, and space. Viruses can only reproduce by invading living cells.

<h3>Answer:</h3>

d) 1 and 4

<h3>Explanation:</h3>
  • Elements are made up of particles known as atoms.
  • Atoms of the same element have the same properties as the element.
  • The atoms of an element may differ in terms of the number of neutrons and have a different mass number, such atoms are known as isotopes.
  • However, the isotopes have an equal number of protons or atomic number.
  • In this case, atom 1 has a mass number of 20 and an atomic number of 10 while atom 4 has a mass number of 21 and an atomic number of 21.
  • Therefore, atom 1 and 4 are isotopes of element E.

Calculate the number of moles 3.16 g of KMnO4 32.33 g of K2CrO4 100 g of KHCO3
kvasek [131]
The number of moles:
3.16g of KMnO_{4}
1 mole of KMnO_{4}- 158g.
x moles of KMnO_{4}- 3.16g.
x=\frac{1\ mole*3.16g}{158g}=\frac{3.16}{158}=0.02\ mole

The number of moles:
32.33g of K_{2}CrO_{4}
1 mole of K_{2}CrO_{4}- 194g.
x moles of K_{2}CrO_{4}- 32.33g.
x=\frac{1\ mole*32.33g}{194g}=\frac{32.33}{194}=0.17\ mole

The number of moles:
100g of KHCO_{3}
1 mole of KHCO_{3}- 100.1g.
x moles of KHCO_{3}- 100g.
x=\frac{1\ mole*100g}{100.1g}=\frac{100}{100.1}=0.999\ mole
