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:

cutting paper is not an example of chemical change.

Explanation:

cutting paper is physical change, its physical properties (size, shape ) change but chemical composition remain same.

The cutting paper is not a example of chemical change of a chemical reaction.

The kind of reaction in which one kind of element get converted into another kind of elements or molecule is referred as chemical reaction.

Chemical changes take place when a material combines with the other to generate a new substance, a process known as chemical synthesis, or when a molecule decomposes into  more than one separate chemicals, a process known as chemical decomposition. These processes are known as chemical reactions, and they are generally irreversible unless they are followed by more chemical reactions.

Cutting paper is just a physical change not chemical change since the paper's characteristics did not change; only the shape, which would be a physical attribute, changed. The term "chemical change" refers to a change in a substance's chemical properties. Burning of paper, for example, or rusting of iron.

Therefore, cutting paper is not a example of chemical change.

The acceptable method to directly measure volume using the metric system using a graduated cylinder to measure gallons. Thus, option C is correct.

The angles and relative measurements of a polished gem and the relationships between them are called proportion. Proportion is defined as equation in which two ratios are set equal to each other.

The relationship among the different things or parts with respect to comparative size, degree and number. There are several types of proportion and these are direct proportion, compound proportion, continued proportion, and inverse proportion.

Gravitational force is a force which act on objects which have a matter i.e a object which contains mass. Gravitational force is force which act between two objects which have a mass and both object are try to attract each other.

Therefore, The acceptable method to directly measure volume using the metric system using a graduated cylinder to measure gallons. Thus, option C is correct.

Option A:

Dig into the zone of aeration

Explanation:

Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.

Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.

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.

Acero

Explanation:

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.

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

Solution B

1 mole of CaCl₂ = 40 + 35.5 = 75.5 g

? moles of CaCl₂ = 119.6g

[tex]\frac{119.6}{75.5}[/tex] = 1.584moles

1.584 moles of MgO is in 2 liters of water

Explanation:

Using ideal gas equation as follows;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question;

P = 0.72atm

V = 22 L

T = 30°C = 30 + 273 = 303K

n = ?

Using PV = nRT

n = PV/RT

n = (0.72 × 22) ÷ (0.0821 × 303)

n = 15.84 ÷ 24.88

n = 0.64 mol
