Define Mole Concept give 3 Significance of Mole concept
Answer:
The mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.
In the International System of Units, the mole is the unit of substance quantity. How many elementary entities of a certain substance are present in an item or sample is determined by the quantity of that material.
Three significance of Mole concept are:
1) Since atoms and molecules are so tiny, we can count them using the mole idea by weighing extremely little quantities of material.
2) It sets a benchmark for figuring out the stoichiometry of reactions.
(3) It explains the characteristics of gases.
The mole is specified as exactly 6.02214076×10²³ elementary entities.

The movement of blood from your lungs to your heart is ______.
A. picks up nutrients, water, and waste materials
B. pulmonary circulation
C. the lungs, where it picks up oxygen again
D. capillaries
E. 5
F. systemic circulation
Answer:
B. Pulmonary Circulation
Explanation:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
The ions S-2, Cl-1, K+, Ca+2, Sc+3 have the same total number of electrons as the noble gas argon. How would you expect the radii of these ions to vary?
Answer:
Cl^- <S^2-<Sc^3+ <Ca^2+<K^+
Explanation:
We know that ionic radius of ions decreases from right to left in the periodic table. This is because, ionic radii decreases with increase in nuclear charge. This explains why; Sc^3+ <Ca^2+<K^+.
Secondly, even though Cl^- is isoelectronic with S^2-, the size of the nuclear charge in Cl^- is larger compared to that of S^2- . Hence Cl^- is smaller than S^2- in ionic radius owing to increased nuclear attraction in Cl^-.

5) Chlorine has 7 valence electrons. Neon has 8 valence electrons. Which on is more likely to undergo a
chemical reaction, and why?
Answer:
well, chlorine will undergo in a chemical reaction
Explanation:
neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.
whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence
it will take place in a chemical reaction

If 2.5 grams of calcium bromide reacted with excess lithium oxide, how many grams of bromide product would be formed?
Answer: 2.17 g of bromide product would be formed
Explanation:
The reaction of calcium bromide with lithium oxide will be:
[tex]CaBr_2+Li_2O\rightarrow 2LiBr+CaO[/tex]
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of calcium bromide}=\frac{2.5g}{199.9g/mol}=0.0125moles[/tex]
As lithium oxide is in excess, calcium bromide is the limiting reagent.
According to stoichiometry :
1 mole of [tex]CaBr_2[/tex] produce = 2 moles of [tex]LiBr[/tex]
Thus 0.0125 moles of [tex]CaBr_2[/tex] will require=[tex]\frac{2}{1}\times 0.0125=0.025moles[/tex] of [tex]NH_3[/tex]
Mass of [tex]LiBr=moles\times {\text {Molar mass}}=0.025moles\times 86.8g/mol=2.17g[/tex]
Thus 2.17 g of bromide product would be formed
Question 1

PLEEEASSEEEE HELPPPPP!!!!!Take some time to research a utility plant. If there is one in your area, you may even visit it.
Otherwise, look up a type of plant that produces energy - such as a nuclear power plant, a
hydroelectric plant, or a coal-burning plant. Find out what energy resources are brought into the
plant. Then find out what energy and what "waste" is produced by the plant. Describe how the
two Laws of Thermodynamics apply to what you find out in your research. Be thorough. You will
be using the information you gather to engage in a debate with your class about
thermodynamics.
Answer:
There are four laws of thermodynamics that define fundamental physical quantities (temperature, energy, and entropy) and that characterize thermodynamic systems at thermal equilibrium.

which is more reactive oxygen or hydrogen? explain why?
Answer:
Explanation:
Which is more reactive hydrogen or oxygen?
Hydrogen is not particularly reactive. For example, just mixing hydrogen and oxygen gas will not cause a reaction at room temperature, but many metal elements oxidize at least on the surface in air. ... It is combustible because oxygen wants electrons and takes them from hydrogen to form water.
One of the steps to sweeten sour gas using the Claus process is reacting
hydrogen sulfide gas with sulfur dioxide gas to produce water vapour and sulfur.
16 H2S(g) + 8 SO2(g) → 16 H2O(g) + 3 Sg(s)
8.56 kL of hydrogen sulfide at 175 kPa and 250 °C reacts with excess sulfur
dioxide. Calculate the mass, in kg, of sulfur produced.
The mass, in kg, of Sulfur produced : 2.072 kg
Further explanationGiven
V = 8.56 kL = 8560 L
P = 175 kPa = 1,73 atm
T = 250 + 273 = 523 K
Required
mass of Sulfur produced
Solution
mol of H₂S :
[tex]\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.73\times 8560}{0.082\times 523}\\\\n=345.3[/tex]
mol of Sulfur based on mol H₂S as a limiting reactant( excess Sulfur dioxide)
From equation, mol ratio H₂S : S = 16 : 3, so mol S :
[tex]\tt \dfrac{3}{16}\times 345.3=64.74[/tex]
Mass S(Ar = 32 g/mol) :
= mol x Ar s
= 64.74 x 32
= 2071.68 g = 2.072 kg

Given that,
The equation is : [tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+?O_2[/tex]
To find,
The missing coefficients.
Solution,
[tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+?O_2[/tex]
Let the value of ? is x.
It is the equation of photosynthesis.
In LHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 18
In RHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 6
If we make the equation as [tex]6CO_2+6H_2O+\text{sunlight}\rightarrow C_6H_{12}O_6+6O_2[/tex]
No the number of atoms in RHS = 6+ 12 = 18
It means if we take the value of ? as 6 the equation will be balanced.
Hence, the correct option is (B) "6".
Metals tend to — electrons and nonmetals tend to —
Electrons
Answer:
Non-metals tend to gain electrons to attain Noble Gas configurations. The have relatively high Electron affinities and high Ionization energies. Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal.
