Electrical conductivity, electromagnetism, and temperature are the features that one would look for in order to determine plasma. Plasma refers to a hot ionized gas possessing high electrical conductivity. It is electrically neutral with negative and positive particles. It can be considered the most abundant form of matter in the universe.
The features of plasma are substantially distinct from those of the usual neutral gases so that plasmas are regarded as a different fourth state of matter.
Answer:
Within a group trend
Explanation:
The atomic radius of atoms generally increases from top to bottom within a group trend. As the atomic number increases down a group, there is again an increase in the positive nuclear charge. As the atomic number increases within a period, the atomic radius decreases.
The atomic mass of the elements making up MgCl₂ are;
Mg - 24.3
Cl - 35.45
The formula mass of MgCl₂ is 24.3 + (2x35.45) = 95.2
One formula is made of 6.022 x 10²³ formula units of MgCl₂
the formula mass of 95.2 contains 6.022 x 10²³ formula units
Therefore a mass of 34.6 g -
number of MgCl₂ formula units are - 2.19 x 10²³ formula units
Answer:
A) SiO2 is the limiting reactant
B) Theoretical yield= 72333.3g
C) % yield =91.5%
Explanation:
SiO2(s) + 2C(s) --------------> Si(s) + 2CO(g)
n(SiO2)= 155000/60 = 2583.33 mols
n(C)= 79000/12= 3291.66 mols
a)SiO2 is the limiting reactant
According to the balanced reaction equation,
60g of SiO2 produced 28g of SiO2
155000g of SiO2 will produce 155000×28/60= 72333.3g
Therefore theoretical yield of Si= 72333.3g
% yield= 66200/72333.3×100/1 =91.5%
