Chemistry

IceJOKER [234]3 years ago

Explanation:

1.A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume.

A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction.

2.This property measures the ability of chemical change. Examples of chemical properties are reactivity, flammability, and oxidation state.

The physical properties of a substance do not involve any chemical reaction. These include density, color, mass, hardness, freezing points, electrical properties, and the like.

Chemical properties include the reaction of chemicals with other substances. These reactions lead to the disappearance of the raw material and the appearance of new materials that have different physical and chemical properties.

3.Chemical properties can be compared to physical properties; On the contrary, they are recognizable without changing the structure of matter. However, for many properties in the field of physical chemistry and other disciplines at the boundary between chemistry and physics, the distinction can be a matter for the researcher's point of view. The properties of materials, both physical and chemical, can be seen as metaphysical; This means that it is secondary to the principle of tangible reality. Multiple metamorphic layers are also possible.

What is the percent by mass of 54.7g of calcium chloride dissolved in 500g of water?
Advocard [28]
% by mass = (mass solute/mass solution)*100%
mass  of the solute = 54.7 g
mass of the solution = mass solute + mass solvent=54.7+500=554.7 g
% by mass = (54.7/554.7)*100%≈0.0986*100% = 9.86%

In this lab, you are to carry out the formation of a Grignard reagent from 1-bromo-benzene andits subsequent reaction with solid
yan [13]

Answer:

(A). C6H5Br + Mg(in ether) -----------> C6H5MgBr.

(B). C6H5MgBr + O = C = O -----------> C6H5-COO^- Mg^+ Br.

(C). C6H5-COO^- Mg^+ Br + HCl --------> C6H5-COOH + Mg^+Br(OH).

PRODUCTS=> C6H5-COOH and Mg^+Br(OH).

Explanation:

A Grignard reagent is a reagent that/which is an organometallic compound that is R -Mg- X. The R = alkyl, vinyl or allyl and the X = halogens.

It must be noted that an important reaction of Grignard reagent is its reaction with compounds containing the Carbonyl that is -CO functional group and this kind of Reaction is known as a Grignard Reaction.

So, in this question we are told that;

=> "1-bromo-benzene andits subsequent reaction with solid carbon dioxide (CO2) followed by acidic workup (using HCl asthe acid). "

Thus;

(A). C6H5Br + Mg(in ether) -----------> C6H5MgBr.

(B). C6H5MgBr + O = C = O -----------> C6H5-COO^- Mg^+ Br.

(C). C6H5-COO^- Mg^+ Br + HCl --------> C6H5-COOH + Mg^+Br(OH).

If 80.0 grams of oxygen gas is consumed with a stoichiometric equivalent of aluminum metal, how many grams of aluminum oxide (mo
Pachacha [2.7K]

Answer:

170 g

Explanation:

Moles of Oxygen gas :

Given, Mass of Oxygen = 80.0 g

Molar mass of Oxygen gas= 31.998 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{80.0\ g}{31.998\ g/mol}

Moles\ of\ O_2=2.5\ mol

The reaction between Al and O₂ is shown below as:

4Al + 3O₂ ⇒ 2Al₂O₃

From the reaction,

3 moles of O₂ on reaction forms 2 moles of Al₂O₃

1 mole of O₂ on reaction forms 2/3 moles of Al₂O₃

2.5 moles of O₂ on reaction forms (2/3)*2.5 moles of Al₂O₃

Moles of Al₂O₃ = 1.6667 moles

Molar mass of Al₂O₃ = 102 g/mol

Mass = Moles * Molar mass = 1.6667 * 102 g = 170 g

Taking logarithms and antilogarithms is necessary to solve many chemistry problems. For practice,
shepuryov [24]

The values of N, log N and ln N are all worked out below.

We have the number N as 8.99

hence;

1) lnN = ln(8.99) = 2.196

log N = log (8.99) = 0.954

2) If we have ln N as 3.949

N = e^3.949 = 51.88

So;

log N = log (51.88) = 1.715

3) log N = 0.134

N = Antilog (0.134 ) = 1.36

ln N = ln (1.36) = 0.307
