Describe how hydrogen and oxygen form water.

Chemistry

Hydrogen and Oxygen by themselves have 1 and 6 valence electrons, respectively. 8 valence electrons is stable, so the atoms form bonds with each other to achieve 8 valence e-.

1 H atom + 1 H atom + 1 O atom = 8 valence e-

The oxygen atom requires 2 electrons to complete its valance shell. Hydrogen is special in that it can eighter give or take one electron and still be stable. So hydrogen gives its electron  to oxygen, and two hydrogens fill up all of oxygen's  valance shell, and it forms water.

What is the mass of 5.31×1021 platinum atoms?
prisoha [69]
<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We calculate as follows:

 </span>5.31×10^21 platinum atoms ( 1 mol / 6.022 x 10^23 atoms ) ( 78 grams / 1 mol ) = 0.6878 grams platinum

Briefly describe the water cycle
Xelga [282]
The water cycle is a cycle that makes water go in the sky and back on ground again. It has 3 main processes which are Condensation: water droplets collect on a cold surface and combine with humid air, Evaporation: the process of a liquid turning into a gas, and Precipitation: The process of water falling from the sky like; rain, snow, sleet, and hail.

58-Ni has an atomic number of 28 which are the protons and a mass number of 58. Since the mass number is 58 this is the protons
Kaylis [27]

Answer:

Explanation: Nickel is element number 28 on the period table with a mass number 58 or 60, it exist in two forms and the phenomenon is known as isotopy

Definition of Isotopy is simply a phenomenon whereby elements exist in various forms that have the exact same chemical properties but different atomic mass.

58-Ni has atomic number 28 because that's the number o the element on the periodic table. Proton number is the same as atomic number and same as electron number for a neutral element or element without charge.

Mass number = Proton number (P) + Neutron number (N)

58 = 28 + N

N= 58-28

N= 30

58-Ni has 28 has the atomic number, proton number and electron number because it is a neutral atom but the neutron is 30 as shown in the calculation above.

60-NI+2 has a contrasting figure because the element has a charge of +2

Mass number= Proton + Neutron

60 = 28 + N

N= 60 - 28

N= 32

Electron = Proton - Charge

                 28 - (+2)

                  28 - 2

Electron = 26

The number of electron in 60-Ni +2 differs from 58-Ni because of the number of charge

Electron number differs from proton number in any element with a charge.

K2CO3 = K2O +
never [62]

Answer:

K2CO3 = K2O + CO2

Explanation:

In a chemical equation, the number of atoms on the left needs to be balanced with the number of atoms on the right, and there has to be the same number of the same *type* of atom on both sides as well.
On the left:
2 K
1 C
3 O
and on the right,
2 K
1 O

On the right, there are a few atoms missing, specifically, 1 C and 2 O.
The missing atoms then should be added to the side missing the atoms, preferably in a stable molecule. Luckily, CO2 contains exactly 1 C, and 2 O s, and is quite stable. So, a "CO2" has to be added on the left
