Hazards Identification

Answers

Answer 1

Answer:

Hazards Identification

Explanation:

A safety data sheet, SDS, is an informational document provided by the manufacturer or importer of a hazardous chemical detailing the chemical, physical, health, and environmental health hazards associated with the chemical as well as safety precautions in handling the chemical.

Some of the sections in the SDS include:

Product Information: It identifies the chemical as well as its recommended uses. The contact information of the manufacturer is also provided.

Fire fighting methods: It gives measures and guidelines necessary for fighting a fire caused by the chemical.

Physical and chemical properties: states the physical and chemical properties of the chemical substance such as:  appearance, odor, pH, melting/freezing point, boiling point and boiling range, flammability, etc.

Hazards identification: states the hazards of the chemical and the necessary warnings regarding the hazards. Some of the information provided include: hazard classification of the chemical (for example flammable liquid, oxidizing gases,explosives, etc), signal word, hazard statement (for example radioactive), pictograms, precautionary statements, etc.

From the above information provided, the student should refer to the hazards identification section.

which of the following flouride has the highest lattice energy a)NaF b)KF c)CsF d)LiF

Answers

Answer:

The correct option is;

d) LiF

Explanation:

The Lattice energy of ionic compounds can be calculated using the modified Coulomb's law as follows;

[tex]U = \dfrac{k' \cdot Q_1\cdot Q_2}{r_0}[/tex]

Where;

Q₁ and Q₂ =  The ionic charges

k' = A constant depending on the ionic and valence configuration

r₀ = The distance between the two nucleus

Given the four compounds each of the metallic ions are of the same group (group one) have the same (only one) valence electron, and are combined to the same ion (fluoride ion) such that Q₂, is the same for all compounds, the factor that will influence the lattice energy more will be the r₀

The sizes of the atoms Li, Na, K and Cs increases as arranged as such Li has the least r₀, and therefore LiF the least  lattice energy

From chemistry test online, we have;

The lattice energy of LiF = -1045 kJ/mole

The lattice energy of NaF = -924 kJ/mole

The lattice energy of KF = -822 kJ/mole

The lattice energy of CsF = -737 kJ/mole.

how many carbon atoms are in .650 gram tablet of aspirin (C9H8O4)?​

Answers

Answer:

For example, in a molecule of aspirin, C9H8O4, there are 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms. compound.

Explanation:

The carbon atoms are in 0.650 gram tablet of aspirin (C9H8O4) is 3.24 x 10² atoms.

What are atoms?

Atoms are defined as the smallest unit of matter that can be divided without releasing electrically charged particles.

After the Big Bang, the building blocks of matter were generated is known as atoms.

Molar mass of aspirin = 180.2 g

Number of carbon atoms

= 0.650 g x 1 mole aspirin / 180.2 g x 9 / 1 mole aspirin

= 3.24 x 10² atoms

Thus, the carbon atoms are in 0.650 gram tablet of aspirin (C9H8O4) is 3.24 x 10² atoms.

A-Volume
B-Weight
C-Mass
D-Density

Answers

Answer:

The correct answer is B

Explanation:

This question seeks to test the difference between mass and weight.

Mass is a measurement of the amount of matter present in an object. While weight is a measurement of the force of gravity pulling (the mass of) an object. Hence, measuring the weight of the moon rocks in the moon might be a waste since the weight of the object on earth will produce a different value due to the difference in the force of gravity between the earth and the moon.

• Calculate relative formula masses from formulae and
from balanced equations?

Answers

Answer:

Explanation:

Simple molecules have very small masses. Instead of writing their actual masses in grams or kilograms, we usually use their relative formula masses. These are calculated using the chemical formula and the relative atomic masses of the elements in it.

Relative formula mass

Relative atomic mass has the symbol Ar. The Ar for an element is a measure of the mass of its atoms compared to the mass of carbon-12 atoms. The greater the Ar value, the more mass an element's atoms have. The periodic table shows the Ar value for each element. For example, the Ar for carbon is 12, and the Ar for magnesium is 24. This means that a magnesium atom has twice the mass of a carbon atom.

Calculating relative formula mass

Relative formula mass is given the symbol Mr. To calculate the Mr for a substance:

work out how many atoms of each element there are in the chemical formula

add together the Ar values for all the atoms of each element present

For example, the formula for carbon dioxide is CO2. It consists of one carbon atom (Ar = 12) and two oxygen atoms (Ar = 16):

Mr of CO2 = 12 + 16 + 16 = 44

It could also be calculated this way:

Mr of CO2 = (1 × 12) + (2 × 16) = 12 + 32 = 44

Ar and Mr values are just numbers. They have no units because they are relative masses.

Relative formula masses of ionic compounds

Ionic compounds such as sodium chloride do not exist as molecules. However, their relative formula masses are calculated in the same way. The formulae used are their empirical formulae.

What is wavelength of light ?

The wavelength of light can be defined as the distance between the two successive  troughs of the light wave, and  It is denoted by the Greek letter lambda (λ), simply it can be said as the distance between one crest or trough of one wave and the next wave is known as wavelength.

The Visible Light having wave length ranges from 400 nm to 700 nm and the spectrum of visible light has a number of colors having different wavelengths.

For example, The violet color have the shortest form of wavelength whereas the red color have the longest wavelength, wavelength is inversely proportional to the frequency like  longer the wavelength of the light have lower is the frequency.

O a suspension and a solution

a colloid and a solution

Answers

Answer:

a colloid and a solution

Explanation:

When solute particles completely dissolve in a solvent, a true solution is formed. The solute particles in this case are so little that they can not be seen with naked eyes. A true solution does not scatter rays of light.

In a false solution, the solute particles are larger than the solute particles in true solutions but are not large enough to be seen with naked eyes. False solutions scatter rays of light. False solutions are also called colloids.

The major difference between a solution and a colloid is that colloids scatter light rays (Tyndall effect) while a true solution does not scatter light rays.
