What is the number of atoms of oxygen in 0.1 mol of CuSO4.5H2O? & explain
A sample of gas occupies 20 mL at -109 degree C. What volume does the sample
occupy at 65 °C?
Answer: V2= 41.2mL
Explanation:
Givens:
* V1= 20ml
* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K
* V2 = ??
* T2= 338.15 K
Use Charles law V1/T1 = V2/T2
Since we are looking for V2 we can rearrange the formula to
V2= (T2 x V1) /T1
V2= (338.15K x 20mL) / 164.15 K
V2= 41.2mL
NOTE:
Temperature should always be in K not in ⁰C or ⁰F
To convert from C to K use
*K= ⁰C + 273.15
Enter your C value in the ( ⁰C ) and you can get K

Answer in units of mol.
mol,
Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?
The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].
The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.
After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.

2. Use the graph below to answer the following questions.
Does this graph represent an endothermic or an exothermic reaction?
How do you know this graph represents that type of reaction?
What is the potential energy of the reactants (PEreactants)?
What is the potential energy of the products (PEproducts)?
What is ΔH of the reaction?
REMEMBER: ΔH = PEproducts - PEreactants
What is the activation energy (Ea) of this reaction?
REMEMBER: Activation Energy = Maximum Energy - PEreactants
Answer:
The graph represents an endothermic reaction.
The products have more energy than the reactants.
80kJ
160kJ
80kJ
160kJ
The given graph is representing an endothermic reaction as the potential energy reactants are lower than that of the products.
ΔH of the reaction and activation energy is 80 KJ and 160 KJ respectively.
What is the endothermic process?An endothermic process can be defined as a process with an increase in the enthalpy H of the system. An endothermic process involves an increase in the temperature of the system.
Whether a process occurs spontaneously depends not just on the enthalpy change but also on the entropy change and temperature.
From the graph, the potential energy of the reactants = 80 KJ
The potential energy of the products = 160 KJ
ΔH of the reaction, ΔH = PE(products) - PE(reactants)
ΔH = 160 -80 = 80 KJ
The activation energy (Ea) of this reaction will be:
Activation Energy (Ea) = Maximum Energy - PE(reactants)
Activation Energy = 240 - 80 = 160 KJ

Synthetic fibers, like plastic, are derived from organic compounds. These fibers have been chemically changed by humans to last longer for better storage and more effective uses. These fibers are stronger than naturally occurring fibers like cotton and wool. Which of the following is a downside to these synthetic fibers when compared to natural fibers?
A.
The longer lasting material is more difficult to break down.
B.
The longer lasting material is less useful in manufacturing.
C.
The longer lasting material is not able to withstand high temperatures.
D.
The longer lasting material makes the fibers more expensive to buy.
The downside of this is that the longer lasting material is more difficult to break down.
Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.
The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

what are the relationships among bond order, bond length, and bond energy?
Explanation:
When a bond is strong, there is a higher bond energy because it takes more energy to break a strong bond. This correlates with bond order and bond length. When the bond order is higher, bond length is shorter, and the shorter the bond length the greater the bond energy.

Explanation:
A scientist was in the field when he saw a mineral sample. He wanted to determine the relative hardness of the mineral, so he conducted scratch tests. He summarized his results in a table. A 2 column table with 4 rows. The first column is labeled Mineral with known hardness with entries: Chalcopyrite, pyrite, Orthoclase, Quartz. Second column is labeled Was a scratch produced? with entries: Yes, Yes, Yes, No. What conclusion can you make about the hardness of the mineral?.
The mineral hardness depends on its resistance to being scratched. Mohs scale is used to determine the hardness of an unknown mineral. The unknown mineral is harder than Orthoclase, but not harder than Quartz.
-------------------------
The hardness of a mineral is its resistance to being scratched or marked on the surface by another material.
Several elements are used to test the hardness of a mineral, like another mineral of known hardness.
Many different scales can be used to identify the mineral. However, the most commonly used is the Mohs scale.
Let us say that you have two minerals. You already know which mineral is one of them and its hardness.
If the unknown mineral scratches the known mineral, means that the first one is harder than the second one.But if the unknown mineral does not get to scratch the known one, it means they are equally hard, or the known mineral is harder than the unknown one.In the exposed example, the table must be as follows
Mineral Was a scratch produced?
Chalcopyrite YES
pyrite YES
Orthoclase YES
Quartz NO
Quartz is the hardest of these minerals. Its hardness level is 7 according to the Mohs scale.
Because scratches were produced using Chalcopyrite, Pyrite, and Orthoclase, we can assume that the unknown mineral is harder than these three ones.
However, no scratch was produced using quartz, suggesting that the unknown mineral is between orthoclase and quartz in the Mohs scale.
The unknown mineral is harder than Orthoclase, but not harder than Quartz. It is between 6 and 7 hardness levels.
