Explanation:

a) The word equation is;

silver chlorate + sodium phosphate ------> silver phosphate + sodium chlorate

b) The balanced reaction equation of the reaction is;

3AgClO3(aq) + Na3PO4(aq) ------->Ag3PO4(s) + 3NaClO3(aq)

c) amount of silver chlorate reacted = 287 g/191.319 g/mol = 1.5 moles

3 moles of silver chlorate yields 1 mole of silver phosphate

1.5 moles of silver chlorate yields 1.5 * 1/3 = 0.5 moles of silver phosphate

Amount of sodium phosphate reacted = 52.8 g/163.94 g/mol = 0.3 moles

1 mole of sodium phosphate yields 1 mole of silver phosphate

0.3 moles of sodium phosphate yields 0.3 moles of silver phosphate.

Hence the maximum number of grams mass of silver phosphate produced = 0.3 moles * 418.58 g/mol = 125.6 g

d) The excess reactant is silver chlorate while the limiting reactant is sodium phosphate

e) 3 moles of silver chlorate  reacts with 1 mole of sodium phosphate

  x moles of silver chlorate reacts with 0.3 moles of sodium phosphate

x = 3 * 0.3 = 0.9 moles of silver chlorate reacted

Mass of 0.9 moles of silver chlorate = 0.9 moles * 191.319 g/mol  = 172 g of silver chlorate

Hence mass of silver chlorate left over =  287 g - 172 g = 115 g

Answer:

Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral

Answer:

60.0L of hydrogen are needed

Explanation:

Based on the reaction:

3H₂ + N₂ ⇄ 2NH₃

3 moles of hydrogen react 1 mole of nitrogen.

To solve this question we have to find the moles of nitrogen. With the moles of nitrogen we can find the moles of hydrogen. Using PV = nRT at STP conditions we can find the volume as follows:

Moles Nitrogen -Molar mass: 28g/mol-

25.0g N₂ * (1mol / 28g) = 0.893 moles N₂

Moles hydrogen:

0.893 moles N₂ * (3mol H₂ / 1mol N₂) = 2.679 moles H₂

Volume hydrogen:

PV = nRT

V = nRT / P

Where V is volume in liters,

n are moles of the gas: 2.679 moles

R is gas constant: 0.082atmL/molK

T is absolute temperature: 273.15K at STP

P is 1atm at STP

Replacing:

V = 2.679mol*0.082atmL/molK*273.15K / 1atm

V =

Answer: A. Aluminum is a conductor because the outer electrons of its atoms can move freely.

Explanation: Quizzed

The statement which best describes Aluminium is Option A , Aluminum is a conductor because the outer electrons of its atoms can move freely.

A substance with high electrical conductivity, luster, and malleability, which readily loses electrons to form positive ions (cations).

Metals conduct electricity because they have “free electrons.”

Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom.

This allows the delocalized electrons to flow in response to a potential difference.

Aluminium is a metal and so a conductor.

Therefore , the statement which best describes Aluminium is Option A , Aluminum is a conductor because the outer electrons of its atoms can move freely.

Explanation:

The elevation in temperature of water by the addition 4.27 g of sucrose to 15.2 grams is 0.42 °C. Thus the boiling point changes from 100 to 100.42 °C.

Boiling point of a substance is the temperature at which the pressure of gas above the liquid phase equals the atmospheric pressure where conversion of liquid to solid takes places.

By the addition of a non-volatile solid to the solution, the boiling point increases and the increase in boiling point ΔT is proportional to the molality of the solution.

ΔT  = Kb m

Where, Kb is called the ebullioscopy constant. Kb for water is 0.52 K Kg/mol.

Molar mass of sucrose = 342 g/mol

no.of moles in 4.27 grams = 4.27 /342 = 0.0124.

mass of solvent = 15.2 = 0.0015 Kg.

Molality = no/ of moles of solute/ mass of solvent in kg

             = 0.015 Kg ×0.0124 mol

             = 0.82 mol/Kg.

Now, the increase in temperature ΔT = 0.82 mol/Kg × 0.52 K Kg/mol.

                                                              =  0.42 °C

Thus, the new boiling point will be 100 + 0.42 °C = 100.42 °C.

Answer:

The volume of the container is 249.367 cm³

Explanation:

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (kg/m³) or gram per cubic centimeter (g/cm³).

In this case:

Replacing:

[tex]0.790 \frac{g}{cm^{3} } =\frac{197 g}{volume}[/tex]

Solving:

[tex]volume=\frac{197 g}{0.790 \frac{g}{cm^{3} } }[/tex]

volume= 249.367 cm³

The volume of the container is 249.367 cm³

Answer:

he mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbons molar mass is 12.011 g/mol, and magnesium's molar mass is 24.3050 g/mol. To see why these elements have different molar masses, we need to remember that the atoms of different elements contain different numbers of protons, neutrons, and electrons, so they have different masses. The atomic masses given in the periodic table inside the front cover of this book represent the different weighted average masses of the naturally occurring atoms of each element. Different atomic masses lead to different molar masses.

For example, the atomic mass of magnesium (24.3050) shows us that the average mass of magnesium atoms is about twice the average mass of carbon atoms (12.011), so the mass of 6.022 x 1023 magnesium atoms (the number of atoms in 1 mole of magnesium) is about twice the mass of 6.022 x 1023 carbon atoms (the number of atoms in 1 mole of carbon). Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbons molar mass of 12.011 g/mol.
