What is toxic chemical exposure?

Answers

Answer 1

Chronic exposure is prolonged, continuous, or recurrent contact with a harmful chemical (months or years).

Meaning of the term multitudes

The term "masses" designates a sizable, all-inclusive group of commoners — members of a society's middle class.If you're extremely wealthy, you'll go in a private plane while the average person takes a crowded bus.The mass don't include royalty, rich people, famous individuals, or anyone in positions of power.The masses consist of everyone else.

The three masses are what?

The three Christmas Masses—at midnight, dawn, and during the day—have a murky history, similar to many liturgical customs.Christmas as just a liturgical holiday celebrated on December 25 first appeared in Rome, somewhere about the year 330.

At what temperature would the volume of a gas be 0.550 L if it had a volume of 0.432 L at –20.0°C? Be careful! This is not in the correct units for temperature.

Answers

Answer:

49.2°C is the temperature

Explanation:

Based on Charles's law, the absolute temperature of a gas is directly proportional to the volume under constant pressure. The equation is:

V1 / T1 = V2 / T2

Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.

Computing the values of the problem:

V1 = 0.432L

T1 = -20.0°C + 273.15K = 253.15K

V2 = 0.550L

T2 = ?

0.432L / 253.15K = 0.550L / T2

322.3K = T2

322.3K - 273.15 =

What is Molecule and atom ?

Atom is smallest entity of a body. Body is made up of atoms. it is basic building block of a body. An atom consist of electrons, protons and neutrons as sub atomic particle. whole mass of the atom is concentrated at the center of the atom which we call it as nucleus, nucleus consist of proton and neutron. Electron revolve around the nucleus at determined(fixed) orbit. Total number of protons in the atom decides the atomic number and the elements in the periodic table.

Molecule is made up of atoms, it is formed when two or more atoms bound together. The electrons in the outermost orbit are responsible for the molecule formation. Electrons are shared by the atoms in the entire molecule.

In this problem the structure shown in this figure is a structure of 2-methylhexane. Hence option B is correct.

What volume of DI water, in mL, must you use to dissolve 30.0 g of NaOH in order to make a 1.25 M solution? mL (round to whole number)

Answers

Answer:

600mL

Explanation:

Molarity of a solution (M) = number of moles (n) ÷ volume (V)

number of moles = mass/molar mass

Molar mass of NaOH = 23 + 16 + 1

= 40g/mol

mole = 30/40

n of NaOH = 0.75mol

Using Molarity = n/V

V = number of moles ÷ molarity

V = 0.75 ÷ 1.25

V = 0.6L

In milliliters (mL), the volume of NaOH will be 0.6 × 1000

= 600mL

Albino trees exist in nature, but they’re rare. These trees contain a gene mutation that causes them to lack chlorophyll, so their leaves are white. In California, albino redwood trees are parasites. They survive off the energy from nearby redwood trees. Why do you think they need to use energy from other trees to survive?

Answers

Answer:

They need to use energy from other tress to survive so that they can do basic functions, like absorbing nutrients from the ground, and growing back leaves. They don't have chlorophyll, so they need that energy to do the functions I mentioned above.

Explanation: Hope this helps!

Answer:

Trees need chlorophyll to make energy. Because albino trees don’t have chlorophyll, they can’t create their own energy. So, they must take energy from other trees to survive.

How many grams of KOH are needed to make 0.500 L of a 0.10 M solution

Answers

Answer:

2.8 g KOH

Explanation:

We can find the amount of moles we need by multiplying 0.500 L and the molarity given, 0.10 M (molarity is moles of solute divided by liters of solution). The liters cancel out, leaving us with moles; we can then take the moles and convert it to grams of KOH by using the molar mass of KOH.

0.500 L x 0.10 mol/1 L x 56.106 g /1 mol = 2.8 g KOH (two significant figures)

How many ATOMS are in 5 grams of NaCl?

Answers

Answer:

2 atoms

Explanation:

Sodium Chloride or NaCl is made up of two elements, sodium (or Na) and chlorine (or Cl). A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total.

2原子。塩化ナトリウムまたはNaClは、ナトリウム(またはNa)と塩素(またはCl)の2つの元素で構成されています。

There are approximately 3.01 x 10²² atoms in 5 grams of NaCl.

To calculate the number of atoms, we first need to convert the mass of NaCl into moles. The molar mass of NaCl is 58.44 g/mol, which is the sum of the atomic masses of sodium (22.99 g/mol) and chlorine (35.45 g/mol).

Using the formula:

moles = mass / molar mass

we can calculate the number of moles of NaCl in 5 grams:

moles = 5 g / 58.44 g/mol ≈ 0.0857 mol

Next, we need to use Avogadro's number, which is approximately 6.022 x 10²³ atoms/mol, to convert moles into atoms.

Number of atoms = moles x Avogadro's number

Number of atoms = 0.0857 mol x 6.022 x 10²³ atoms/mol ≈ 5.16 x 10²² atoms

Therefore, there are approximately 3.01 x 10²² atoms in 5 grams of NaCl.

It's important to note that this calculation assumes that all the NaCl is fully dissociated into its constituent atoms, which may not be the case in all situations.

The N in ammonia has 1 lone pair and three bonds (to H).

The O in water has 2 lone pairs and two bonds (to H)

the F in Hydrogen fluoride has 3 lone pairs and one bond.

Answer:In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared pair or non-bonding pair.

A solid substance turns directly into a gas. Which term describes this change?

A)deposition
B)evaporation
C)melting
D)sublimation

Answers

Given what we know, we can confirm that the correct term to describe the change from a solid into a gas is sublimation.

What is sublimation?Sublimation is the change from a solid-state into a gas state.Most of the time one will first observe the change into a liquid state, however, with sublimation, the change is directly from the solid into the gas, such is the case with dry ice. Dry Ice is frozen carbon dioxide, as it thaws, it changes directly into its gaseous state.

Therefore, we can confirm that sublimation describes the process by which an element passes from a solid directly into a gas, without first becoming a liquid.

Answers

Answer:

The large relative distances between particles in a gas means that there is considerable empty space between the particles.

The assumption that particles in a gas are relatively far apart explains gas compressibility.

Compressibility is a measure of how much the volume of matter decreases under pressure.

Energy is released by a gas when it is compressed

Explanation:

The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.

Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
