The given oxygen and lithium atoms are unable to form a stable compound.
The given atoms to form a stable compound has been oxygen and lithium.
A stable compound has been formed when the transfer of atom has been resulted in the completion of the valence shell of both the electrons.
The oxygen has 6 valence electrons and require to gain 2 electrons to form the stable compound. The Lithium has 3 electrons and has been able to lose 1 electron to form a stable compound.
Since, the formation of stable compound between oxygen and lithium requires transfer of 2 electrons, and there has been availability of 1 electron from Li. Thus, the atoms are unable to form a stable compound.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, height of Column of gas is 7.4cm and temperature of Gas is 82°C or 355 K.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Height of Column of gas is 7.4cm and temperature of Gas is 82°Cor 355 K.
Therefore, height of Column of gas is 7.4cm and temperature of Gas is 82°C or 355 K.

A) 1 X 10-14 M
C) 1 x 10-9M
B) 1 x 10-12 M
D) | 10-2M
Answer:
= 1 X 10⁻⁻¹²M
Explanation:
At 25°C & 1atm [H⁺][OH⁻] = 1 x 10⁻¹⁴ => [H⁺] = 1 X 10⁻¹⁴/[OH⁻] = 1 X 10⁻¹⁴/1 X 10⁻²

explain the general properties of group 1 elements in relation to their electronic configuration
Answer:
The elements in Group 1 (lithium, sodium, potassium, rubidium, cesium, and francium) are called the alkali metals. All of the alkali metals have a single s electron in their outermost principal energy. ... For example, the electron configuration of lithium (Li), the alkali metal of Period 2, is 1s22s1.
Answer:
they have a mono positive charge of +1
Explanation:
this is due to having one electron in their outermost ns orbital
10. Although lidocaine is marketed as its hydrochloride salt, it doesn’t exhibit the same level of physiological activity as the free amine. The free amine is more lipophilic and diffuses across a neuron cell membrane more rapidly than the ionic salt, resulting in a more rapid onset of anesthesia. Therefore, sodium bicarbonate (NaHCO3) is added to a solution of lidocaine prior to injection. How does the addition of sodium bicarbonate promote a faster anesthetic effect?
Answer:
Bicarbonate neutralizes the acidity of Lidocaine and hence reduce the pain
Explanation:
Alkalinization by addition of sodium bicarbonate causes buffering of local anesthetics and hence produce faster anesthetic effect such as pain control, pain reduction while injecting the patient and faster onset of local anesthetics.
Lidocaine along with epinephrine results into acidic compound wit respect to subcutaneous tissue. Hence, when bicarbonate is added, it neutralizes the acidity of Lidocaine and hence decrease the pain.
1. You and a friend are hiking through a canyon. You tell your friend that the rock layers in the canyon are all different ages, and you can
tell which rock layers are the oldest and which are the youngest. She picks four different rock layers on the canyon wall, as shown in the
photograph
Which layer is the youngest?
A. Layer 1
O B. Layer 2
C. Layer 3
D. Layer 4
Answer:
its number 4 D layer 4
Explanation:
just look at it look at the colors so that's how you know and plus it just old
Answer:
From what I gathered from researching, I would say that Layer 2 is the correct answer to the question you asked.
Explanation:
The reason I'd say it is Layer 2 is because the lower you look in a canyon, the farther back you look in time. Over that canyon's history, more layers are added on top of the rock and ground as erosion and weathering happen.
Layer 2 is the highest up, which means that it was added the most recent of the other layers. Although there are more things that could maybe be taken to account, the best answer I see from what information you were given in this question... Layer 2 is the correct answer.

How many moles of NaCl are contained in 50.0 mL of 2.50 M NaCl?
Answer: 0.144 moles. :)
Explanation:
The number of moles of NaCl that are contained in 50.0 mL of 2.50 M NaCl is 0.125 moles
Using this formula
Molarity=Moles of solute/Liters of solution
First step is to convert 50.0 mL to Liters
Litres=50.0 ml×1 L/1000 ml
Litres=0.05 L
Now let determie the number of moles of NaCl
2.50M=moles/0.05
moles=2.50M(0.05)
moles = 0.125 moles of NaCl
Inconclusion The number of moles of NaCl that are contained in 50.0 mL of 2.50 M NaCl is 0.125 moles

What is the reducing agent in the following reaction?
2 Br−(aq) + H2O2(aq) + 2 H+(aq) → Br2(aq) + 2 H2O(l)
Answer:
the reducing agent is Bromine
The oxidation state of an element is calculated by subtracting and the total sum of oxidation states of all the individual atom (excluding the one that has to be calculated) from total charge on the molecule. Bromine is the reducing agent in the following reaction.
What is oxidation state?Oxidation state of an element is a number that is assigned to an element in a molecule that represents the number of electron gained or lost during the formation of that molecule or compound.
The ionic equation is given as
2 Br⁻(aq) + H[tex]_2[/tex]O[tex]_2[/tex](aq) + 2 H⁺(aq) → Br[tex]_2[/tex](aq) + 2 H[tex]_2[/tex]O(l)
The oxidation state of bromine on reactant side is -1 while on product side it is 0 so, oxidation state of bromine has increased by 1 so, bromine is oxidized. If it is oxidized that means it must have reduced someone. So, bromine is acting as a reducing agent.
Therefore, bromine is the reducing agent in the given reaction.

Use the Lewis model to determine the formula for the compound that forms from each pair of atoms.
Express your answer as a chemical formula.
1) K and I
2) Mg and F
Answer:
[tex]KI\\\\MgF_2[/tex]
Explanation:
Hello there!
In this case, since the Lewis dot structures are able to show the number bonds, required atoms and valence electrons of each bonding species, it is necessary to keep in mind that potassium has one valence electron, iodine has seven, magnesium has two and fluorine has seven; therefore, we can infer that the compound KI has one bond whereby iodine is able to attain the octet and the compound MgF needs two fluoride ions to fill out those two valence electrons of magnesium to obtain MgF₂, since the Lewis structures are:
[tex]K-I\\\\F-Mg-F[/tex]
Therefore, the chemical formulas are just:

Answer:
B. The cells.

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
Glucose can be consumed for energy in three ways one ends with glucose being converted into CO2,
another way it is converted into lactic acid/actate, and the third way ends with ethanol. We humans use
the first two ways. What do we call each of the three ways? When/why would we use each of the first
two ways, and why not the third way?
Answer:
In humans, there are two major processes used to convert glucose into energy. cellular respiration or aerobic respiration is one of these processes that take place in presence of oxygen that converts glucose into CO2.
The other process is lactic acid fermentation occurs in muscles in case of depletion of oxygen which converts glucose into lactic acid.
The third process is alcoholic fermentation does not take place in humans and occurs in yeast and some bacteria where they produce ethanol.
Humans cannot use alcoholic fermentation in their own body ferment as there is no genetic information in us to do so as it has encoded in yeast and bacteria.
