Answer:
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
It can cause a deadly reaction to skin if not treated for a long time
Answer:
One of each
Explanation:
Be is in Group 2, so it loses its two valence electrons in a reaction to form Be²⁺ ions.
Carbonate ion has the formula CO₃²⁻.
We can use the criss-cross method to work out the formula of beryllium carbonate.
The steps are
Write the symbols of the anion and cation.
Criss-cross the numbers of the charges to become the subscripts of the other ion.
Write the formula with the new subscripts.
Divide the subscripts by their highest common factor.
Omit all subscripts that are 1.
When you use this method with Be²⁺ and CO₃²⁻, you might be tempted to write the formula for the beryllium carbonate as Be₂(CO₃)₂
However, you can divide the subscripts by their largest common factor (2).
This gives you the formula Be₁(CO₃)₁.
We omit subscripts that are 1, so the correct formula is
BeCO₃
There is one Be²⁺ ion and one CO₃²⁻ ion in a formula unit of beryllium carbonate.
The same column elements are called "groups" these are elements have the same outer electron arrangement which would lead to similar physical and chemical behavior. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Tetrahedral molecular geometry is the only one that can exist for sp3 hybridized center atoms.
<h3>Which chemical contains an sp3 hybridized central atom?</h3>
- An atom that is bound and a nonponding pair of electrons are the two different kinds of electron domains.All bonded atoms count as one electron domain on the center atom, regardless of whether they are connected by a single, double, or triple bond.
- There are five fundamental geometries for electron domains. The core oxygen atom in the water molecule has six valence electrons.The 6 valence electrons of oxygen are arranged in hybridized sp3 orbitals, resulting in 2 paired and 2 free electrons.
- One s orbital and three p orbitals combine to generate four sp3 orbitals, each of which has a 25% s character and a 75% p character. This process is known as sp3 hybridization.
- An example of CO2 can be used to illustrate how lone pairs of electrons make up an SP3 hybrid orbital.We are only able to count bond pairs or lone bonds.
