How many grams of Ag2S
are produced from 10.0
grams of AgI?
10
AgI + Nazs
Ag2S +NaI

Answers

Answer:

10.0 g of AgI will produce 5.28 g of Ag₂S

Explanation:

The balanced equation of the reaction is given below:

2AgI + Na₂S ----> Ag₂S + 2NaI

From the equation of reaction, 2 moles of AgI produces 1 mole of Ag₂S

The moles of a substance is related to its mass by a quantity known as molar mass which is defined as the mass of one mole of that substance.

Molar mass of AgI = (108 + 127) g = 235 g

Molar mass of Ag₂S = (108 × 2 + 32) g= 248 g

Mass of 2 moles of AgI = 2 × 235 g = 470 g

470 g of AgI produces 248 g of Ag₂S

10 g of AgI will produce 248 /470 × 10 g of Ag₂S = 5.28 g

Therefore, mass of Ag₂S produced = 5.28 g

How many grams of MgCl2 are produced by 2.55 mol Mg?

Answers

Answer: m = nM= 242.8 g

Explanation: amount of MgCl2 is same as n(Mg)

M(MgCl2) = 95.21 g/mol

95.21 g/mol is the mass in grams of MgCl[tex]_2[/tex] are produced by 2.55 mol Mg in the reaction Mg + 2HCl ⟶ MgCl[tex]_2[/tex] + H[tex]_2[/tex].

What is mass?

A body's mass is an inherent quality. Prior to the discoveries of the concept of atom as well as particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to accelerate (change of velocity) in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

m = n×M= 242.8 g

M(MgCl[tex]_2[/tex]) = 95.21 g/mol

Therefore, 95.21 g/mol is the mass in grams of MgCl[tex]_2[/tex] are produced by 2.55 mol Mg in the reaction Mg + 2HCl ⟶ MgCl[tex]_2[/tex] + H[tex]_2[/tex].

De la reacción 3Zn+ 2H2PO4----> Zn3(PO4)2 +2H2 por cada 9 moles de zinc cuantos moles de fosfato de zinc se producen

Answers

Answer:

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

Explanation:

La reacción balanceada es:

3 Zn+ 2 H₂PO₄ → Zn₃(PO₄)₂ + 2 H₂

Por estequiometria de la reacción (es decir, la relación entre la cantidad de reactivos y productos en una reacción química), las siguientes cantidades de moles de cada compuesto participan de la reacción:

Zn: 3 moles H₂PO₄: 2 moleZn₃(PO₄)₂:1 mole H₂: 2 moles

Entonces podes aplicar la siguiente regla de tres: si por estequiometria 3 moles de zinc produce 1 mol de fosfato de zinc, 9 moles de zinc cuántos moles de fosfato de zinc producirá?

[tex]moles de fosfato de zinc=\frac{9 moles de zinc*1 mole de fosfato de zinc}{3 moles de zinc}[/tex]

moles de fosfato de zinc= 9

Por cada 9 moles de zinc, 9 moles de fosfato de zinc se producen.

I went for a walk the other day. I went four blocks east, then seven blocks south, then one block west and finally
eight blocks north
a.What distance did I travel?
b. What's my displacement?

Answers

Answer:

a) distance is 4+7+1+8=20 blocks

b) displacement is 10 blocks

Explanation:

find displacement: x and y

x axis displacement = 4-1 = 3 blocks

y axis displacement = -7+8= 1 block

displacement = the square root of 3^2 + 1^2

= 9+1 = 10 blocks.

You can find the angle of displacement with respect to the initial position using trig identities, if you wish.

Which of the following is an example of nonpoint source pollution?
A. industrial effluent
B. Agricultural runoff
C. illegal dumping of waste
D. Oil leaking from your car

Answers

Answer:

Option C.

Ilegal dumping of waste

Explanation:

This is because non point source of pollution refers to source of pollution that are many and not directly one which is illegal or does not meet the legal term. This type of pollution does not have a point source, it has many sources and this type of pollution is cause by rainfall or precipitation. Where when the rain fall, it wash away the waste through to water bodies, causing pollution and endangering water bodies.

An artificial vesicle containing a 1 M glucose solution is composed of a phospholipid bilayer lacking any protein components other than aquaporin channels. Assuming an ideal solution, what is the ratio of the osmotic pressure measured immediately after immersion of the vesicle in de-ionized water to the osmotic pressure measured immediately after immersion of an identical vesicle containing the original volume of 1 M glucose solution added to an equal volume of 1 M KCl solution in deionized water

Answers

Answer:

A: 0.67

The situation described in the question is analogous to a semipermeable membrane. Water is able to pass through aquaporin channels present in the liposome, but large uncharged particles (glucose) and ions (K+ and Cl -) are impermeable and will remain trapped within the liposome. If assumed to be ideal, the osmotic pressure, π, exerted by the solution due to molarity differences across the membrane is defined as π = iMRT, where i is the van't Hoff factor, M is the molarity of the solution, R is the universal gas constant, and T is the absolute temperature of the solution. A change in osmotic pressure at constant temperature is due to changes in iM, a term that is equivalent to the concentration of dissolved particles produced by solute in solution. When compared to the original volume of 1 M glucose, the new combined solution has twice the volume and three times the number of dissolved particles (1 M KCl, a strongly electrolytic solution, produces 1 M concentrations of both K+ and Cl- in solution), or an increase in the concentration of dissolved particles by a factor of 1.5. This is equivalent to a combined molarity of dissolved particles of 1.5 M. The ratio of osmotic pressure is then [1 M dissolved glucose] / [1.5 M dissolved glucose + KCl] = 0.67
