What mass of silver chloride can be produced from 1.01 L of a 0.196 M solution of silver nitrate?
Express your answer with the appropriate units.
Mass of Silver chloride-AgCl = 28.314 g
Further explanationGiven
1.01 L of a 0.196 M solution of Silver nitrate
Required
Mass of Silver chloride
Solution
Reaction
AgNO₃ + NaCl ⇒ AgCl + NaNO₃
mol of AgNO₃ :
mol = M x V
mol = 0.196 x 1.01
mol = 0.198
From equation, mol ratio of AgNO₃ : AgCl = 1 : 1, so mol AgCl = 0.198
mass AgCl (MW=143 g/mol) :
mass = mol x MW
mass = 0.198 x 143
mass = 28.314 g

Select the correct answer. Which notation is used to represent a beta particle?
Explanation:
I think the notation used to represent beta is B
Answer:
[tex]\frac{0}{-1} \beta[/tex]
Explanation:
A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.[2]
Beta particles with an energy of 0.5 MeV have a range of about one metre in air; the distance is dependent on the particle energy.
Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue, but also the lower the penetrating power of the radiation.

below. Manganese has a relative atomic mass of 55 and oxygen has a relative atomic mass of 16. What is the
value of y in the formula below?
The empirical formula : MnO₂.
Further explanationGiven
632mg of manganese(Mn) = 0.632 g
368mg of oxygen(O) = 0.368 g
M Mn = 55
M O = 16
Required
The empirical formula
Solution
You didn't include the pictures, but the steps for finding the empirical formula are generally the same
Find mol(mass : atomic mass)Mn : 0.632 : 55 = 0.0115
O : 0.368 : 16 =0.023
Divide by the smallest mol(Mn=0.0115)Mn : O =
[tex]\tt \dfrac{0.0115}{0.0115}\div \dfrac{0.023}{0.0115}=1\div 2[/tex]

Answer:
Heat is carried away from the pot in all different directions. This shows: RADIATIONWarm water rises within the pot. This shows: CONVECTIONHeat moves from the flame to the pot's bottom. This shows: CONDUCTIONExplanation:
Conduction involves transfer of heat energy through a solid medium; convection involves heat transfer of fluid particles in their masses, while thermal radiation is transfer via electromagnetic waves in a vacuum.
I hope this was helpful.
Lets study what conduction, convection and radiation are:
Conduction explains the process in which the transfer of heat takes place between objects by direct contact. Convection refers to the form of heat transfer in which energy transition occurs within the fluid. It helps the heat to pass through fluids. Radiation helps the heat to flow through empty spaces.Learn more:

(1 Point)
O Cs- and F-
Cs- and F+
Cs+ and F-
Cs and F only
Answer:
Cs+ and F-
Explanation:
The compound CsF is made up of two elements; Caesium (Cs) and F (Flourine)
Caesium is a metal and would therefore lose electrons - a cation is formed. When Caesium loses a single electron, the ion symbol is given as; Cs+
Flourine is a non metal and would therefore gain electrons - an anion is formed. When Flourine gains a single electron, the ion symbol is given as; F-
Hence the correct option is;
Cs+ and F-

which of the following gases can be dried using concentrated sulfuric acid? Ammonia, Chlorine, Hydrogen Chloride.
Answer:
Both chlorine [tex]{\rm Cl_2}\, (g)[/tex] and hydrogen chloride [tex]{\rm HCl}\, (g)[/tex].
Concentrated sulfuric acid should not be used to dry ammonia because ammonia itself would react with sulfuric acid.
Explanation:
Keep in mind that concentrated sulfuric acid is:
Acidic, andCapable of oxidizing many substances.Because of its acidity, concentrated sulfuric acid will readily react with gases that form basic solutions when mixed with water. Therefore, concentrated sulfuric acid should not be used to dry those gases. Neither should concentrated sulfuric acid be used to dry gases that might lose electrons to concentrated sulfuric acid. Otherwise, a significant portion of those gas would be consumed in those unexpected chemical reactions.
AmmoniaAmmonia is one such gas. Because the solubility of ammonia in water is remarkably high, the humid ammonia gas in this question would likely exist in the form [tex]\rm NH_4OH[/tex]. When that gas comes into contact with sulfuric acid [tex]\rm H_2SO_4[/tex], the following reaction could take place:
[tex]\rm 2\, NH_4OH + H_2SO_4 \to (NH_4)_2 SO_4 + 2\, H_2O[/tex].
As long as concentrated sulfuric acid isn't used up, very little ammonia would exit from the other side of the drying apparatus. Hence, concentrated sulfuric acid shouldn't be used to dry ammonia.
Chlorine and HClConcentrated sulfuric acid does not react with chlorine or HCl under typical lab conditions. Therefore, it should be possible to dry chlorine [tex]{\rm Cl_2}\, (g)[/tex] and [tex]{\rm HCl}\, (g)[/tex] with concentrated sulfuric acid in a lab.

Oxygen and carbon monoxide react to form carbon dioxide as
shown in the following reaction
O2 (g) + 2CO (g) - 2CO2 (g)
If a sample of 70.0 g of carbon monoxide was reacted with
32.0 g of oxygen, how many moles of carbon dioxide would be
produced?
moles
Answer:
The number of moles of carbon dioxide that would be produced is 2 moles
Explanation:
The given reaction is presented as follows;
O₂ (g) + 2CO (g) → 2CO₂ (g)
The parameters given are;
The mass of the carbon monoxide, m₁ = 70.0 g
The mass of the oxygen, m₂ = 32.0 g
The molar mass of carbon monoxide = 28.01 g/mol
The molar mass of oxygen gas O₂ = 32.0 g/mol
The number of moles, n = (The mass)/(The Molar Mass)
The number of moles of carbon monoxide in the reaction = 70.0 g/(28.01 g/mol) = 2.49910746 moles ≈ 2.5 moles
The number of moles of oxygen in the reaction = 32.0 g/(32.0 g/mol) = 1 moles
Therefore, from the chemical reaction, we have;
One mole of O₂ reacts with two moles of CO to produce two moles of CO₂ (g)
1 mole of oxygen produces 2 moles of carbon dioxide
Therefore, given that the number of moles of oxygen in the reaction is 1 mole, we have that the number of moles of carbon dioxide that would be produced = 2 moles.
Sodium atomic radius 1.90
magnesium atomic radius 1.60
aluminium atomic radius 1.32
(a) Explain the trend in the atomic radius across the period.
(b) Predict the the P.H of the solution of sodium Oxide.
Answer:
For a: The increasing of atomic radius is:
Al < Mg < Na
For b: The pH of the solution of sodium oxide is greater than 7.
Explanation:
For (a):Atomic radius is defined as the distance of the nucleus to the outermost shell containing electrons.
It decreases as we move from left to right in a period because electrons get added up in the same shell and effective nuclear charge increased which results in the shrinkage of the atom.
Sodium lies in Period 3, group 1. Its atomic radius is 1.90
Magnesium lies in Period 3, group 2. Its atomic radius is 1.60
Aluminium lies in Period 3, group 3. Its atomic radius is 1.32
The increasing of atomic radius will be:
Al < Mg < Na
The mathematical values proves the result.
For (b):There are 3 types of solution based on pH:
If pH > 7, the solution is basic in nature. If pH < 7, the solution is acidic in nature.If pH = 7, the solution is neutral in nature.When a metal reacts with oxygen present in air, it forms basic oxide which simply means when they react with water, they form basic solution.
The chemical equation for the reaction of sodium (metal) with oxygen present in air and reaction with water of the product so formed are as follows:
[tex]4Na+O_2\rightarrow 2Na_2O[/tex]
[tex]Na_2O+H_2O\rightarrow 2NaOH\text{ (base)}[/tex]
Sodium forms a basic solution when its oxide reacts with water, therefore the pH of the solution will be greater than 7.
