To Find :
How many molecules are in 23 moles of oxygen (O₂).
Solution :
We know, 1 mole of any atom/molecule contains 6.022 × 10²³ numbers of atoms/molecules.
So, number of molecules in 23 moles of O₂ are :
Hence, this is the required solution.
Answer:
Varies
Explanation:
The color of a start can be affected my many things. The temperature at which it burns, the density, the size, its stage of life, and the material that it's made of can all be factors
Answer:
There are two explanations to this: covalent network bonding and carbon-silicate cycle.
Explanation:
A network solid or covalent network solid is a chemical compound which is formed through a continued network of atoms or molecules held together by a covalent bond throughout the system. An example included C-C bond in graphite or C-Si bond in silicon carbide (tentative reaction equation below):
xSiO2 + yCO2→ SixCyO(2x+2y)
Si-Si bonds are not as strong as C-C bonds and can easily be displaced as the particles react with atmospheric CO2.
The second scenerio is when silicates such as calcium silicate CaSiO3, or wollastonite, reacts with atmospheric carbon dioxide and water to yield a calcium ion, Ca2+, a bicarbonate ion, HCO3-, and dissolved silica. This process occurs during carbon-silicate cycle and increase organic carbon content:
2CO2 + H2) + CaSiO3 → + SiO2CaCO3 + CO2 + H2)
Answer:
Magnesium, Mgstart text, M, g, end text, is a group 2 element that will form 2+ cations. Because it usually forms cations of only one type, we don't need to specify its charge. We can simply refer to the cation in the ionic compound as magnesium. ... Therefore, the name for the compound is magnesium phosphide.
