Complete the following chemical equations BaCl2.2H2O
Answers
Answer:
Explanation:
Balancing is making the number of atoms of each element same on both the sides (reactant and product side).
To find the number of atoms of each element we multiply coefficient subscript
For example contains
5 × 1 = 5 ,Ca atoms and
5 × 2 = 10, Cl atoms
If there is a bracket in the chemical formula
For example we multiply coefficient × subscript × number outside the bracket to find the number of atoms
(Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )
So
3 × 3 = 9 , Ca atoms
3 × 1 × 2 = 6, P atoms
3 × 4 × 2 = 24, O atoms are present.
So
Let us balance the equation given
(balanced equation)
Reactant side Elements Product side
1 Ba 1
2 Cl 2
4 H 4
2 O 2
Balanced!!!

Answer:
2 moles ofFerric Oxide () over 4 moles of Fe
Explanation:
Firts of all I want to explain the nomenclature that is involve in the equation:
Ferric Oxide
Carbon
Iron
Carbon Dioxide
Now, to understand the ratio from the balanced equation its necessary read the equation with the respective coefficients, for example:
- 2 moles of Ferric Oxide (
) reacts to produce 4 moles of Iron (
)
- 3 moles of Carbon (
) reacts to produce 4 moles of Iron (
- 2 moles of Ferric Oxide (
) reacts to produce 3 moles of Carbon Dioxide (
)
Each of the above could be represent as a ratio, but is always necessary keep the respective coefficient, then if you read each option only the first has the respective coefficient, it means:
2 moles of Ferric Oxide () reacts to produce 4 moles of Iron (
) or, in other words, 2 moles ofFerric Oxide (
) over 4 moles of Iron 4 (
)

Answer:
- First choice: it provides energy for the reaction.
Explanation:
Alkanes are relative stable molecules: saturated chains of carbon and hydrogen atoms, where each carbon atom is hydridized sp³ and is bonded to one or two carbon atoms and 2 or 3 hydrogen atoms.
The C-H bonds are slightly polar (carbon is more electronegative than oxygen).
On the other hand, the diatomic halogen molecule (F₂, Cl₂, Br₂, or I₂) is a non-polar molecule.
The mechanism of reaction between the alkane and the halogen is via free radicals: the halogen molecule must be splitted into two radicals (two atoms each with a free electron). This implies the rupture of the diatomic halogen, and this requires an important amount of energy. The role of the UV ligth is to provide the energy to split the halogen molecule and, in this way, start the reaction.
Then, the free halogen radical may react with the alkane molecule breaking a C - H bond and substituting the leaving hydrogen atom, forming a C - X bond (X represents the halogen atom).
As a demonstration of this role, you may find in the specialized textbooks this typical reaction:
- CH₄ + Cl₂ + energy → CH₃Cl + HCl
The energy shown in the reactant side may be supplied as UV light or heat. So, the role of UV light is to provide energy to start the reaction.

Final answer:
Hydrogen is a nonmetal that does not exhibit properties such as malleability or ductility. Hydrogen is a unique element in the universe and its physical and chemical properties differ markedly from malleable or ductile elements, such as metals. Thus, hydrogen is neither malleable, ductile, nor brittle.
Explanation:
Hydrogen is a unique element in the universe, and its physical and chemical properties differ significantly from those of elements that are classified as malleable or ductile, such as metals. Properties such as being shiny, malleable, and ductile are characteristics of metals which can be deformed without breaking or drawn into wires, and they conduct heat and electricity well. However, hydrogen is a nonmetal and under normal conditions, it is relatively inactive chemically. It does not demonstrate properties like malleability or ductility as metals do. Hence, hydrogen is not malleable, ductile, or brittle.

Media reflects the society. It shows the true facts about the society. Media plays a very important role in show casing the injustice or the wrong that is going on in the society. It should report all the matters correctly about the violation that occurred. It should not spread any false news but should show the truth behind any violations. It should also aware people about the cause of the violation and also the consequences of it so not it will not be repeated in the future.
