Which of the below elements are part of a group? Feel free to use the periodic table.
A. H, He, O, C
B. Be, Mg, Ca, Sr
C. Li, Be, C, O
D. H, Li, Na, Mg
Answer:
B. Be, Mg, Ca, Sr
Explanation:
Be, Mg, Ca, Sr are parts of the alkaline Earth metal family/group. So they are the second most reactive elements following behind alkali metals. Furthermore, Be, Mg, Ca, Sr all have 2 valence electrons that lose them to form cations. They have low melting points, low boiling points, can conduct electricity, have high malleability and ductility.

The number of moles left = 0.0067 moles
Further explanationGiven
0.28 g CO
2 x 10²¹ molecules removed
Required
Number of moles left
Solution
Initial mol of CO(MW=28 g/mol) :
mol = 0.28 : 28
mol = 0.01
The number of molecules in 0.01 mol :
= 0.01 x 6.02 x 10²³
= 6.02 x 10²¹
2 x 10²¹ molecules removed, so molecules left :
= 6.02 x 10²¹ - 2 x 10²¹
= 4.02 x 10²¹
moles of 4.02 x 10²¹ :
= 4.02 x 10²¹ : 6.02 x 10²³
= 0.0067 moles

What are the coefficients that would correctly balanced reaction
Answer: As a consequence, chemical equations must be balanced, meaning that the number and kinds of atoms must be the same on both sides of the reaction arrow. The numbers placed in front of formulas to balance equations are called coefficients, and they multiply all the atoms in a formula.

what is mechanical wave ?A mechanical wave is defined as an oscillation of matter which is responsible for energy transfer via medium.
The propagation of wave is limited by the medium of transmission, the oscillating material which revolve around a fixed point with little translational motion.
A surface wave which is an example of mechanical wave that propagate along the interface of two different media in physics. other common examples are Gravity waves on the surface of liquids, ocean waves.
Surface wave can be propagated in a slow way through Earth material and are generally lower in frequency than body waves.

Answer:
54.66 liters
Explanation:
First of all, remember this. 1 mole equals 22.4 liters.
Second of all, to show your work use dimensional analysis.
Write 2.44 moles and then put moles on the bottom and liters on top.
2.44 moles of O * 22.4 liters / 1 mol of O
Moles will cancel out.
2.44 x 22.4 = 54.656
Usually I would have used sig figs. But the question said to round your answer to two digits after the decimal point.
54.656 rounds to the hundreths place.
So 54.656 = 54.66
All in all, the final answer is 54.66 liters(don't forget the units).

An unknown compound has the following chemical formula: N2OX here stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 4.00mol of oxygen and 2.67mol of nitrogen. Write the complete chemical formula for the unknown compound.
The complete chemical formula for the unknown compound : N₂O₃
Further explanationGiven
The chemical formula : N₂Oₓ
4.00 mol of oxygen and 2.67 mol of nitrogen
Required
The chemical formula
Solution
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
The molecular formula of a compound shows the mole ratio of each of its constituent components
The mol ratio for N : O =
2.67 : 4 : divide by 2.67

Shivani measures out 6.0 moles of epsom salt (MgSO) to put her bath. How many grams MgSO4 went in the bath?
Answer: 720 g
Explanation:
To solve this we must be knowing each and every concept related to mole. Therefore, shivani measures out 6.0 moles of epsom salt (MgSO[tex]_4[/tex]) to put her bath. 1,566g MgSO[tex]_4[/tex] went in the bath.
What is mole?A mole is merely a measuring unit. In reality, it is one of its International System of Units' seven foundation units. When current units are insufficient, new units are created.
Chemical reactions frequently occur at levels where employing grams would be inappropriate, but using absolute quantities of atoms/molecules/ions would also be misleading.
For all practical reasons, one mole of a substance in grams is nearly equal to 1 molecule for the compound per daltons.
Mathematically,
number of mole =given mass ÷ molar mass
number of mole=6.0 moles
molar mass of epsom= 261.47g/mol
substituting all the given values in the above equation, we get
6.0 moles =mass of epsom ÷ 261.47g/mol
mass of epsom =1,566g
Therefore, 1,566g MgSO[tex]_4[/tex] went in the bath.

The table below shows properties of two compounds at standard pressure. Which statement classifies the two compounds? 1)Both compounds are ionic, 2)Both compounds are molecular, 3) Compound 1 is ionic, and compound 2 is molecular, 4)Compound 1 is molecular, and compound is ionic
Answer:
3) Compound 1 is ionic, and compound 2 is molecular
Explanation:
Compound-1 is an ionic compound while Compound-2 is a molecular compound. Option 3 is correct.
Ionic Compound:
They are formed when an atom donates its electron to another atom. This results in one positive and one negative ion.
Hence, it is a very strong bond. These compounds have a very high melting and boiling point. They are very good electric conductors in the aqueous solution.
For example- NaCl.
Molecular compounds:
They are compounds that are made up of discrete molecular units. For example- [tex]\bold {H_2O}[/tex]
They have very weak intermolecular bonds hence have low boiling and melting point and do not conduct electricity.
SInce Compound-1 has higher MP and BP and Compound-2 has low melting and boiling point.
Therefore, Compound-1 is an ionic compound while Compound-2 is a molecular compound.

Twelve grams of gas occupies 14.5 liters at a pressure of 52.0cm Hg. What is the volume when the pressure has increased to 85.0cm Hg?
Answer:
8.87 L.
Explanation:
From the question given above, the following data were obtained:
Mass (m) of gas = 12 g
Initial volume (V₁) = 14.5 L
Initial pressure (P₁) = 52 cmHg
Final pressure (P₂) = 85 cmHg
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's Las equation as illustrated below:
P₁V₁ = P₂V₂
52 × 14.5 = 85 × V₂
754 = 85 × V₂
Divide both side by 85
V₂ = 754 / 85
V₂ = 8.87 L
Thus the volume of the gas will be 8.87 L

Which of the following would likely occur as a result of an oil spill in the ocean?
I. The levels of salt and other nutrients typically present in ocean water would greatly increase.
II. There would be no more upwelling of nutrients from cold ocean depths.
III. Humans would be less able to use fish and shellfish from the affected area as food.
IV. There would be global interruptions in the water cycle.
A. III only
B. IV only
C. I and III only
D. I, II, III, and IV
Answer:
D.
Explanation:
The Oil spill effects on environments and habitats can be catastrophic: they can kill plants and animals, disturb salinity/pH levels, pollute air/water and more. Read more about the types of oil pollution.
Statements that express occurrences as a result of oil spill in the ocean are:
C: I. The levels of salt and other nutrients typically present in ocean water would greatly increase.
III. Humans would be less able to use fish and shellfish from the affected area as food.
An oil spill can be regarded as a of release liquid petroleum hydrocarbon into the environment.This release can be on land or in the body of water especially ocean, however this spillage is very dangerous to aquatic lives which indirectly affects man.Once spillage occur, levels of salt and other nutrients will increase in the ocean and this can harm aquatic lives.especially the marine ecosystem, due to human activity, and is a form of pollution.
