Answer:
N₃O₆
Step-by-step explanation:
Data:
EF = NO₂
MM = 138.02 g/mol
Calculations:
EF Mass = (14.01 + 32.00) u
EF Mass = 46.01 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
n = MF Mass/EF Mass
n = 138.02 u/46.01 u
n = 3.000 ≈3
MF = (NO₂)₃
MF = N₃O₆
There isn't any molecules in plasma, hope this helps
Answer:
Weight = 98 kg.m/s^2
= 98 N.
Explanation:
Weight of an object is defined as the product of mass of the object and the acceleration due to gravity acting on the object. Its unit is Newton which is denoted as N and is also equivalent to kg.m/s^2.
Mass of the object = 10 kg
Acceleration due to gravity, g = 9.8 m/s^2
Weight = m*g
= 10 kg * 9.8 m/s^2
= 98 kg.m/s^2
= 98 N
Answer:
0.05 M.
Explanation:
For the concentrated sulphuric acid,
Number of moles = molar concentration × volume
= 0.1 × 0.1
= 0.01 mol
New volume = 100 + 100 ml
= 200 ml
Concentration of the diluted sulphuric acid = number of moles/volume
= 0.01/0.200
= 0.05 M
Answer:
B. Large atoms tend to have a low ionization energy and a low electron affinity.
Explanation:
Atomic radii can be defined as a measure of the size (distance) of the atom of a chemical element such as hydrogen, oxygen, carbon, nitrogen etc, typically from the nucleus to the valence electrons. The atomic radius of a chemical element decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon). Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).
Generally, atoms with relatively large atomic radii tend to have a low ionization energy and a low electron affinity. Ionization energy can be defined as the minimum energy required to remove or detach an electron from a neutral atom in a gaseous state. Electron affinity can be defined as the ability of an atom of a chemical element to accept or accommodate an electron.
