Answer:

True

Explanation:

A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).

Very glad I could help you!!

Find the number of molecules in 27 grams of water
Aleks04 [339]

In this question we have given the gram of water and we know that 1 mole of water = 18 gram of water and 27 g of water contain 1.5 g of water 27 / 18 = 1.5 g

As we know that avogandro'S no is equal 6.022*1023

1.5g * 6.022*1023 = 9.0 * 1023 molecules present in each 27 g of water.

I hope you will understand better now if you like then comment below and tell me. Best of luck.

PLEASE HELP I HAVE LIMITED TIME!!
n200080 [17]

Answer:

Explanation:

Si tomamos en cuenta el peso molecular del agua, que es equivalente a:

1 Átomo de H₂O

O = 16 gr/mol

H = 1 gr/mol

H₂O = 18 gr/mol

Teóricamente sabemos que en 1 mol de H2O habrá 18 gr.

 

Para obtener los moles presentes en 1 mg de H₂O, (como 1 gr = 1000 mg), decimos:

1 mol H2O …………………………..  18000 mg

       X          ……………………………   1 mg

X = 1 / 18000 = 5,56 X 10⁻⁵ moles de H20

 

Y para obtener la cantidad de moléculas presentes, de acuerdo a los moles, multiplicamos por el número de Avogadro (6,023 X 10²³ moléculas /mol)

Moléculas de H₂O = 5,56x 10⁻⁵ mol x 6,023 x 10²³

Moléculas de H₂O = 3,34488 x10¹⁹ moléculas de H₂O

En el copo de nieve habrá 3,34488 x 10¹⁹ moléculas de H₂O.

Espero que te sirva =)

Identify whether the description refers to a monomer, a polymer, or both. Macromolecule:
larisa86 [58]

Answer:

Macromolecule: polymer

Repeating units: monomer

Simple molecule: monomer

Covalent bonds: both

Explanation:

A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.

A  monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.

Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
