Which of the following can survive either with oxygen or with out it

Answers

Answer 1

Facultative anaerobes.

Organisms that grow in the absence of free oxygen are termed anaerobes; those that grow only in the absence of oxygen are obligate, or strict, anaerobes. Some species, called facultative anaerobes, are able to grow either with or without free oxygen.

calculate the number of moles of Cu in 2.4x10^21 atoms of Cu

Answers

Answer:

0.004 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{2.4 \times {10}^{21} }{6.02 \times {10}^{23} } \\ = 0.003986[/tex]

We have the final answer as

0.004 moles

Explain why it was important for scientists to have a standard system of naming compounds and other chemical procedures.

Answers

he primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. The form of nomenclature used depends on the audience to which it is addressed.

It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.

Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.

Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.

A sample of Element X is found to contain 82.15% of isotope type 1 (84.9118 amu)
and 17.85% of isotope type 2 (86.9092 amu). Calculate the average atomic
mass.

Answers

Answer:

Have you gotten your answer yet?

The average atomic mass of element X is 85.26 amu.

To calculate the average atomic mass of Element X, we need to take into account the abundance of each isotope and its respective atomic mass.

First, let's assign variables to the abundance and atomic mass of each isotope:

- Isotope 1: abundance = 82.15%, atomic mass = 84.9118 amu

- Isotope 2: abundance = 17.85%, atomic mass = 86.9092 amu

To calculate the average atomic mass, we can use the following formula:

average atomic mass = (abundance₁ ×atomic mass₁) + (abundance₂ ×atomic mass₂)

Substituting the values:

average atomic mass =

[tex]\dfrac{82.15\times84.9118}{100}+\dfrac{17.85\times86.9092}{100}\\=85.26 \ \rm{amu}[/tex]

Thus, average atomic mass of element X is 85.26 amu.

What are the processes of heat transfer?

Heat transfer processes refers to the process by which heat energy is transferred from one point to another within a medium of between two points.

There are three processes of heat transfer, namely:

ConductionConvection, and Radiation

Conduction is a process of heat transfer in which is transferred from one point to another in a medium without the actual movement of the particles of that medium.

During conduction, the particles of the medium vibrate about a mean position as they acquire heat. This heat energy is then transferred from that particle to the neighboring particle as they particles are in close contact. Hence the heat is transferred from one particle to the next.

How many moles of HCl can be produced from 0.207 g of SOC12 SOC12(1) + H2O(1) = SO2(g)+ 2HCl(g) ​

Answers

Answer:

.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂

Explanation:

The balanced reaction is:

SOCl₂ + H₂O ----> SO₂ + 2 HCl

By stoichiometry of the reaction they react and produce:

SOCl₂: 1 mole

H₂O: 1 mole

SO₂: 1 mole

HCl: 2 mole

Being:

S: 32 g/mole

O: 16 g/mole

Cl: 35.45 g/mole

H: 1 g/mole

the molar mass of the compounds participating in the reaction is:

SOCl₂: 32 g/mole + 16 g/mole + 2*35.45 g/mole= 118.9 g/mole

H₂O: 2*1 g/mole + 16 g/mole= 18 g/mole

SO₂: 32 g/mole + 2*16 g/mole= 64 g/mole

HCl: 1 g/mole + 35.45 g/mole= 36.45 g/mole

Then, by stoichiometry of the reaction, the following amounts of mass react and are produced:

SOCl₂: 1 mole* 118.9 g/mole= 118.9 g

H₂O: 1 mole* 18 g/mole= 18 g

SO₂: 1 mole* 64 g/mole= 64 g

HCl: 2 mole* 36.45 g/mole= 72.9 g

Then the following rule of three can be applied: if by stoichiometry of the reaction 118.9 grams of SOCl₂ produce 2 moles of HCl, 0.226 grams of SOCl₂ how many moles of HCl do they produce?

moles of HCl= 3.80*10⁻³

3.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂
