Compare the viscosity property of solid and liquid.
Answers
Answer
There is nothing like viscosity in solid because most of the solids usually have a rigid body. This is due to strong intermolecular forces. And it is due to this strong force between the molecules that they are unable to move and they remain fixed at their position. Some solids such as graphite which have layered structure, don't possess the property of viscosity, because of the strong force between the layers.
Explanation:
Viscosity is the property of a fluid that opposes the relative motion between two surfaces of the fluid that are moving at different velocities. In simple terms, viscosity means friction between the molecules of fluid.
FOR EXAMPLE
water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity

Fluorine (F) and bromine (Br) are in the same group on the periodic table. How do atoms of these elements compare when they form bonds?
Both a fluorine atom and a bromine atom lose one electron, and both atoms become stable.
A fluorine atom becomes stable by losing one electron, but a bromine atom cannot become stable by losing only one electron.
Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.
A fluorine atom becomes stable by gaining one electron, but a bromine atom cannot become stable by gaining only one electron.
Answers
Answer:
Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.
Explanation:
The two elements compare when they form bonds in that when both a fluorine atom and a bromine atom gain one electron, they both become stable.
Fluorine and bromine are elements called halogens. They both belong to group 7 on the periodic table. When they gain an electron each, they become isoelectronic with a corresponding noble gas. This gives their atom special stability.Answer:
3) Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable

Ionic bonding, Covalent bonding, Metallic bonding.
» My memory
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. » Wikipedia
How much water (H2O ) would form if 4.04 g of hydrogen (H2) reacted with 31.98 g of oxygen (O2 )?
(2H2 + O2 2H2O)
Answers
Answer:
Mass = 36 g
Explanation:
Given data:
Mass of water formed = ?
Mass of hydrogen = 4.04 g
Mass of oxygen = 31.98 g
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 4.04 g/ 2 g/mol
Number of moles = 2.02 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 31.98 g/ 32 g/mol
Number of moles = 1.0 mol
Now we will compare the moles of water with hydrogen and oxygen.
O₂ : H₂O
1 : 2
H₂ : H₂O
2 : 2
2.02 : 2.02
Number of moles of water formed by oxygen are less thus oxygen will limiting reactant.
Mass of water:
Mass = number of moles × molar mass
Mass = 2 mol × 18 g/mol
Mass = 36 g

The most stable group of elements on the periodic table is the?
A) halogens
B) noble gases
C) alkali earth metals
D) alkaline earth metals
Answers
Answer:
Noble Gases B
Explanation:
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.
Most stable because they have the maximum number of valence electrons their outer shell can hold

Sodium metal reacts violently with water and chlorine is a toxic gas, yet we eat sodium chloride. Why is this possible? Select one: a. The properties of compounds are different from the properties of the elements that form the compounds.
b. The properties of compounds are identical to the properties of the elements that form the compounds, and we should not eat sodium chloride because it is toxic.
c. The physical properties of compounds are different from the physical properties of the elements that form the compounds, but the chemical properties of the elements and compound are the same.
d. The chemical properties of compounds are different from the chemical properties of the elements that form the compounds, but the physical properties of the elements and compound are the same.
Answers
Answer:
The properties of compounds are different from the properties of the elements that form the compounds.
Explanation:
When elements form compounds, their properties are significantly modified. The physical and chemical properties of compounds and that of the elements that compose them are significantly different.
The introduction of chemical bonds between different atoms in compounds make the compounds to differ from elements where the atoms are bonded to atoms of the same element.

As you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What two processes did you observe?
Answers
Answer:
Weathering and erosion
Explanation:
Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors
. There are 3 common types of weathering which are;
1) physical weathering
2) biological weathering
3) chemical weathering
Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.
Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.
After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks

A laboratory hydrogen generator collects the gas produced by bubbling it through water. The total pressure of the gas collected is 751 mmHg. The temperature is 34 °C, at which water vapor pressure is 40.0 mmHg. Calculate the partial pressure of the hydrogen.
Answers
Answer:
[tex]711\ \text{mmHg}[/tex]
Explanation:
[tex]P_{total}[/tex] = Total pressure = 751 mmHg
[tex]P_{water}[/tex] = Vapor pressure = 40 mmHg
[tex]P_{gas}[/tex] = Pressure of gas
The total pressure in a system is given by Dalton's law
[tex]P_{total}=P_{gas}+P_{water}\\\Rightarrow P_{gas}=P_{total}-P_{water}\\\Rightarrow P_{gas}=751-40\\\Rightarrow P_{gas}=711\ \text{mmHg}[/tex]
The partial pressure of the hydrogen is [tex]711\ \text{mmHg}[/tex]
