Answer:
1 1
5 2
6 1
8 3
10 3
6 3
9 3
13 3
Explanation:
First of you add the subscripts (the little numbers after the letters) and multiply the big numbers before the letters together to get the number of atoms
For Example:
O= 1 atom
Si{2}= 2 atoms
Mg{5}C{6}= 11 atoms
3Na{2}= 6 atoms
O(SiNa){2}= OSi{2}Na{2}= 5 atoms
Each Capital letter is a new Element
For Example:
O = 1 Element
NaSi = 2 Elements
Pressurized gas is the term that is used to describe a gas that is compressed into a smaller space than it would normally occupy at Earth's surface.
Explanation:
The purpose of compressing a gas is to lessen its volume so that it can fit in a small space. Natural gas can be compressed using a compressor and the pressure of a compressed gas is 200 to 250 bars.
Pressurized gases are used in ground processing and space flight operations. Pressurized gas, also known as compressed gas is also used in fuel production and in gas pipelines.
When stored in a reservoir, care must be taken to avoid leakage as these gases compressed under high pressure are highly flammable.
Answer:
a higher electronegativity
Explanation:
In fact, in chemistry Nitrogen, Oxygen and Fluorine are the most electronegative element
Answer:
1s2 2s2 2p6 3s2 3p6 4s2 3d5
Explanation:
According to the Aufbau principle, electrons are filled in orbitals in order of increasing energy. The energy of orbitals in the electronic configuration of manganese increases from left to right, hence 3d orbital is much greater in energy than a 3p orbital.
The arrangement of orbitals in order of increasing energy is shown in the answer above.
