Cation is the postively charged unit which is formed by the transfer of one or more electrons. It is attracted towards cathode thus it is called the CATION.
_____________________________________Question no 2:IONIC BOND:Ionic bond is the type of bond which is formed between the positive and negative ions. It is mostly formed between the Metals (i.e. group 1 and 2) and Non metals (i.e. mostly group 7). The positive charge on metal is due to the loosing of electron and negative charge on non metal is due to accepting the electron.
_____________________________________Question no 3:POLYATOMIC ION:A molecular ion is a covalently bonded set of two or more atoms, that can be considered to behave as a single unit, it also has a charge on it.
_____________________________________Question no 4:CONDUCTIVITY:Conductivity is more in liquid than in solid because the conductivity is flow of electron and the movement is less in solid than liquids thus the solid has less conductivity. The liquid has more movement of molecules due to which there is more conductivity.

HELP!! An unknown solution has a pH reading of 8.4. Which statement is true about this solution?
A. The solution is a strong acid.
B. The solution is a strong base.
C. The solution is a weak acid.
D. The solution is a weak base.
Answers
Answer:
D- a weak base
Explanation:
The ph scale goes from 1-10 a solution over 7ph is classified as basic. A solution thats 8.4 is only 1.4 over 7pH, making it a weak basic solution. An example of a strong base would be a solution with a pH of 9.2 (for example).

Answer:
Volume of HBr = V₂ = 7.5 mL
Explanation:
Given data:
Volume of NaOH =V₁= 25.0 mL
Molarity of NaOH =M₁= 0.150 M
Molarity of HBr =M₂= 0.5 M
Volume of HBr =V₂= ?
Solution:
M₁V₁ = M₂V₂
0.150 M ×25.0 mL = 0.5 M×V₂
V₂ = 0.150 M ×25.0 mL / 0.5 M
V₂ = 3.75 M.mL /0.5 M
V₂ = 7.5 mL
A car is traveling with an initial velocity of 15 m/s when the driver decides to go faster by accelerating at 5 m/s2 for 10 seconds. How far did the car travel during this time?
70 m
300 m
175 m
400 m
Answers
Answer: Time needed: 2.5 s
Distance covered: 31.3 m
Explanation:
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
on one side of the equation and solve by plugging your values
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation

What type of elements make up ionic bonds?
Answers
basically explains
Ionic bonds are formed between ionic compounds, Ionic compounds are formed when metals join with nonmetals.
What are ionic bonds?Ionic bonds are electrostatic bonds that are formed between metals and nonmetals. It is an electrostatic attraction between oppositely charged ions in a chemical compound.
These bonds are formed when two or more atoms lose or gain electrons. An example of ionic bonds can be seen in the NaCl compound.
Na⁺ + Cl⁻ = Na⁺Cl⁻
NaCl is formed by the joining of oppositely charged elements. They constitute salt. Salt is made up of ionic compounds, so it easily dissociates into sodium and chloride when mixed in water.
Thus, ionic compounds are created when metals combine with nonmetals, and these combinations result in the formation of ionic bonds.

How could energy have played a role in the different rock types forming?
Answers
Answer:
Energy from different sources leads to different types of rocks.
Explanation: Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into different types of rock.
Rocks are formed in earth by the deposition of minerals and decomposition of massive tectonic plates by the hot magma which is melted by the heat energy radiated from sun.
What are different types of rocks?There are broadly three different types of rocks, namely sedimentary rocks, igneous rocks and metamorphic rocks . They are classified based on their formation and composition.
The magma that the molten mineral fluid inside the earth crest melts under heat radiated from sun and this hotter fluid flows results in movement of tectonic plates and decomposition at some places.
Therefore, the heat energy and resultant convection current leads the tectonic plate boundaries and formation of different kinds of rocks which are stimulated by the action of air and water.

Fruit fly cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have how many chromosomes? Explain your answer.
Answers
After mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.
MITOSIS:
Mitosis is the kind of cell division in which a single cell produces two daughter cells that are genetically identical to the parent cell. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell, hence, it is called duplication division. This means that mitotic division maintains the chromosome number of parents in the daughter cells. For example, a fruit fly with 8 chromosomes will produce daughter cells with 8 chromosomes each. Therefore, after mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

A helium balloon has a volume of 2.00L at 101kpa. As the balloon rises the pressure drops to 97.0kPa. What is the new volume?
Answers
Answer:
2.08L
Explanation:
V1 = 2.00L
P1 = 101kPa
P2 = 97.0kPa
V2 = ?
from Boyle's law,
P1V1 = P2V2
101 × 2 = 97 × V2
V2 = 202/97 = 2.08L
Therefore, the new volume is 2.08L
Answer:
2.1L
Explanation:
Given parameters:
Initial volume = 2L
Initial pressure = 101kPa
Final pressure = 97kPa
Unknown:
Final or new volume = ?
Solution:
Now to solve his problem which relates pressure and volume, we simply apply Boyle's law which is mathematically expressed below;
P₁ V₁ = P₂ V₂
P and V are pressure and volume
1 and 2 are initial and final states;[tex]\frac{101 x 2}{97}[/tex]
101 x 2 = 97 x V₂
V₂ = [tex]\frac{101 x 2}{97}[/tex]
V₂ = 2.1L

calculate the chemical amount of ammonia present in a 11.22g sample of the compound
Answers
Answer:
3.97 x 10²³atoms
Explanation:
Given parameters:
Mass of ammonia = 11.22g
Unknown:
Chemical amount of ammonia present = ?
Solution:
The chemical amount present in a substance is the number of atoms it contains.
To solve this problem, from the given mass find the number of moles first.
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Number of moles = [tex]\frac{11.22}{17}[/tex] = 0.66mole
1 mole of any substance contains 6.02 x 10²³ atoms
0.66 mole of ammonia will contain 0.66 x 6.02 x 10²³ atoms
= 3.97 x 10²³atoms
