Find the mass of 3.00 mol of acetic acid, C2H4O2.

Answers

Answer 1

Answer: Molar mass

C₂H₄O₂ = 60.0 g/mol

n = mass / molar mass

3.00 = mass / 60.0

m = 3.00 * 60.0

m = 180 g of C₂H₄O₂

When the pressure that a gas exertson a sealed container changes
from atm to 1.80 atm, the
temperature changes from 86.0°C to
30.0°C.

Answers

Answer:

The pressure changes from 2.13 atm to 1.80 atm.

Explanation:

Given data:

Initial pressure = ?

Final pressure = 1.80 atm

Initial temperature = 86.0°C (86.0 + 273 = 359 K)

Final temperature = 30.0°C (30+273 =303 K)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

P₁ = P₂T₁ /T₂

P₁ = 1.80 atm × 359 K / 303 K

P₁ = 646.2 atm. K /303 K

P₁ = 2.13 atm

The pressure changes from 2.13 atm to 1.80 atm.

Which of the notations below is another way to write the name of the following nuclide?A.iodine-53

B.iodide-53

C.iodide-127

D.iodine-127

Answers

Answer: D.iodine-127:

Explanation:

1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).

2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.

3) The mass number is the sum of protons and neutrons.

4) From that, you can tell this about the four choices given:

A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.

B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)

The name iodide is reserved for the ions from iodine not for the atom.

C.iodide-127: incorrect due to the name iodide, for the same reason explained above.

D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)

Answer:

iodine-127

One problem with using pesticides to control insects on crops is that the insects can develop resistance to the chemicals. How is this similar to the overuse of antibiotics?

Answers

Answer:

Explanation:

Overuse of antibiotics leads to bacteria's resistance against our drugs. This is increasing at an alarming rate and the reason is that overuse of antibiotics kills bacteria that lack the "resistance" gene or gene that can help them survive the antibiotics (similar is the case for insects that die to insecticides). But, some bacteria can have random mutations in their gene that can help them survive the antibiotic (similar is the case for some insects that can survive the insecticide), thus the surviving bacteria give rise to next generation of bacteria that are resistant to the given antibiotic (similar to how insects that survive the insecticide give birth to new insects that are resistant to insecticide too). Soon, every generation adds new antibiotic resistant bacteria (or new insecticide resistant insects in the case of insects) which is dangerous for all of life on this planet. Therefore, both are similar in the sense that new generations of these organisms will be resistant to our weapons against them.

Write the name of each of the following Ionic Compounds: Ba3(PO4)2 , MgSO4 , PbO2

Answers

Final answer:

Ba3(PO4)2 is Barium Phosphate, MgSO4 is Magnesium Sulfate, and PbO2 is Lead (IV) Oxide or Plumbic Oxide.

Explanation:

The Ionic Compounds you have mentioned are named as follows:

Ba3(PO4)2 is named Barium Phosphate.
MgSO4 is named Magnesium Sulfate.
PbO2 is named Lead (IV) Oxide or Plumbic Oxide. Always remember for ionic compounds containing transition metals (like Pb), we have to indicate the charge of the cation.

Most modern forms of transportation are powered by fossil fuels. Carbon dioxide, methane, carbon monoxide, and other gases are released into the atmosphere during the production and combustion of these fuels. How might these gases cause climatic changes? These gases have no effect on atmospheric temperatures, so they are unable to cause any type of climatic changes. These gases cause more water vapor to condense, making climates wetter than they were in the past. These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere.
