Answer:
Option C is false statement. The half life of a second order reaction is not dependent on concentration.
Explanation:
Half life of a reaction is defined as the amount of time which is required for a reactant concentration reduced by half comparison to its initial concentration.
Half life of a second order reaction is depend on the initial concentration of a reaction, in contrast to 1st order reaction.
The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.
Example,
ᵇₐX
Where;
b = Mass Number
a = Atomic Number
X = Symbol
For Hydrogen Isotopes:
1) Protium: 1 Proton , 0 Neutron
¹₁H
2) Deuterium: 1 Proton , 1 Neutron
²₁H
3) Tritium: 1 Proton , 2 Neutron
³₁H
Answer:
1500kg/m^3
Explanation:
Formula:
d=m/v
Given:
m=1.5kg
v=1000cm^3
(The side length of a cube is always equal to the others)
Required:
d=?
Solution:
d=m/v
d=1.5kg/1000cm^3
d=1.5kg/0.001m^3
d=1500kg/m^3
Hope this helps ;) ❤❤❤
Answer:
The density.
Explanation:
The density is an intensive property of fluids, defined as mass divided by volume.
This property is directly related to the intermolecular forces that are present in the substance: the stronger the intermolecular forces, the higher the density will be, and viceversa. Therefore, organic fluids usually have lower densities than water, because <u>the intermolecular forces in organic fluids are not as strong as in the intermolecular forcer in water</u> (water has very stable hydrogen bonds, whereas organic fluids have van der Waals, weaker than hydrogen bonds).
The liquid that has the lower density will be the the liquid that is on the top layer. In this case, the organic compound tert-butyl methyl ether will be on top of water.
The nature of ions formed by different atoms is as follows:
- Metal atoms form positively-charged ions
- Non-metal atoms form negatively-charged ions
<h3>What are ions?</h3>
Ions are substances which are formed when neutral atoms gain or lose electrons.
There are two types of ions based on the charge the ion carries;
- anions - which are negatively-charged
- cations - which are positively-charged
The nature of the ions formed by different atoms depend on whether the atoms are atoms of metals or atoms of non-metals.
Metal atoms form positively-charged ions by the loss of one or more electrons as illustrated below:
where; M is a metal atom, M⁺ is a metal ion, and e⁻ is an electron.
Non-metal atoms form negatively-charged ions by the gain of one or more electrons as illustrated below:
where; N is a non-metal atom, N⁻ is a non-metal ion, and e⁻ is an electron.
In conclusion, the nature of ions formed by atoms depends on the nature of the atom, whether they are metallic or non-metallic atoms.
