Answer:
Chemical formula.
Explanation:
A chemical formula have fix proportion of atoms of elements.
Chemical formula:
A chemical formula is the way of presenting the chemical proportion of atoms of those elements, that combine to form a compound.
For example:
Water consist of two atom of hydrogen and one atom of oxygen. The atoms of both elements combine to form a compound i.e water. The atoms of both elements always combine in a fixed ratio which is 2:1 in molecule of water.
H₂O
2:1
Carbon dioxide consist of two atom of oxygen and one atom of carbon. The atoms of both elements combine to form a compound i.e carbon dioxide. The atoms of both elements always combine in a fixed ratio which is 1:2 in molecule of carbon dioxide .
CO₂
1;2
Hey there!:
If Q = K, it means the reaction is at equilibrium.
The correct statments are as follows:
A. If Q < K, it means the forward reaction will proceed to form more products.
B. If Q > K, it means the backward reaction will proceed to form more reactants.
The statement C is true.
Hope this helps!
Answer:
It will reach to its maximum volume.
Explanation:
Using Ideal gas equation for same mole of gas as
:-
Given ,
V₁ = 65.0 mL
V₂ = ?
P₁ = 745 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 745 / 760 atm = 0.9803 atm
P₁ = 0.9803 atm
P₂ = 0.066 atm
T₁ = 25 ºC
T₂ = -5 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
T₂ = (-5 + 273.15) K = 268.15 K
Using above equation as:
Solving for V₂ as:-
V₂ = 868 L
Given that:- V max = 835 L
<u>Thus, it will reach to its maximum volume.</u>
Answer : A metal atom loses electrons from its outermost energy level and acquires a Positive Charge. These electrons join a nonmetal atom. The ionic compound formed because of this transfer of electrons is electrically Neutral.
Explanation :
All the elements try to acquire octet state by gaining or losing electrons. For metals, the number of valence electrons are less and it is easier to lose these electrons.
When electrons are lost, the number of protons become more than the electrons. This creates an excess of positive charge. As a result the species becomes positively charged and is known as cation.
During formation of ionic bond, metals always form a positive ion (cation) by losing electrons. These electrons are accepted by the nonmetals and they become negatively charged. A negatively charged ion is known as anion and nonmetals always form an anion.
These are attracted to each other due to the opposite charges present on them. In an ionic compound they balance the charges on each other making the compound neutral.
From the above discussion, we can fill in the blanks as follows.
A metal atom loses electrons from its outermost energy level and acquires a Positive Charge. These electrons join a nonmetal atom. The ionic compound formed because of this transfer of electrons is electrically Neutral.
