Answer:

a. hydrofluoric acid  - Specialized spill kit is needed

b. special mercury  - Specialized spill kit is needed

c. special phosphoric acid  - General spill kit is Sufficient

d. acetone  - General spill kit is Sufficient

e. general methanol - General spill kit is Sufficient

Explanation:

a. hydrofluoric acid  -

It is a weak acid , and very corrosive therefore , it need Specialized spill kit

b. special mercury  -

At the room temperature , liquid mercury evaporates. But Small amount of mercury can cause harm so , Specialized spill kit is needed

c. special phosphoric acid  -

It is relatively compared to others is a week acid , therefore General spill kit is Sufficient

d. acetone  -

At the room temperature , acetone evaporates, therefore General spill kit is Sufficient

e. general methanol -

At the room temperature , methanol evaporates, therefore General spill kit is Sufficient

A concentration cell is built based on the following half reactions by using two pieces of zinc as electrodes, two Zn2+ solution
Lana71 [14]

Explanation:

The given reaction at cathode will be as follows.

At cathode: Zn^{2+} + 2e^{-} \rightarrow Zn,     E_{o} = -0.761 V

At anode: Zn \rightarrow Zn^{2+} + 2e^{-},       E_{o} = 0.761

Therefore, net reaction equation will be as follows.

                 Zn^{2+} + Zn \rightarrow Zn + Zn^{2+}

Initial:     0.129         -            -       0.427

Change:  -0.047      -            -     -0.047

Equilibrium: (0.129 - 0.047)      (0.427 - 0.047)

                = 0.082                       = 0.38

As E^{o}_{cell} for the given reaction is zero.

Hence, equation for calculating new cell potential will be as follows.

                   E_{cell} = E^{o}_{cell} - \frac{RT}{nF} ln \frac{[Zn^{2+}]_{products}}{[Zn^{2+}]_{reactants}}

                              = 0 - \frac{8.314 atm L/mol K \times 291 K}{2 \times 96500} ln \frac{0.38}{0.082}

                              = 0.019

Thus, we can conclude that the cell potential of the given cell is 0.019.

QUICK WILL MARK BRAINIEST!!!! The general formula for an acid is (__n ___) where _____ stands for hydrogen, n stands for the ___
Olenka [21]

Answer:

The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

Explanation:

The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

An example is H2SO4, also called sulfuric acid

It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2

X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4

Can science be applied to everything you do​
NISA [10]

Answer:

To understand what science is, just look around you. What do you see? Perhaps, your hand on the mouse, a computer screen, papers, ballpoint pens, the family cat, the sun shining through the window …. Science is, in one sense, our knowledge of all that — all the stuff that is in the universe: from the tiniest subatomic particles in a single atom of the metal in your computer's circuits, to the nuclear reactions that formed the immense ball of gas that is our sun, to the complex chemical interactions and electrical fluctuations within your own body that allow you to read and understand these words. But just as importantly, science is also a reliable process by which we learn about all that stuff in the universe. However, science is different from many other ways of learning because of the way it is done. Science relies on testing ideas with evidence gathered from the natural world. This website will help you learn more about science as a process of learning about the natural world and access the parts of science that affect your life.

Ethanol is added to gasoline to produce E-15 and E-85. It promotes more complete combustion of the gasoline and is an octane boo
Artist 52 [7]

Answer:

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Explanation:

Heat of combustion is defined as heat evolved on combustion of 1 mole of a substance.

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Heat combustion of 2,2,4-trimethylpentane =  (1304 kcal/mol) and

C_8H_{18}+\frac{25}{2}O_2\rightarrow 8CO_2+9H_2O,\Delta H=-1,304 kcal/mol

1 mole of 2,2,4-trimethylpentane on combustion gives 8 mole sof carbon dioxide gas and 9 moles of water.

Heat combustion of ethanol = (327 kcal/mol)

C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O,\Delta H=-327kcal/mol

1 mole of ethanol on combustion gives 2 moles of carbon dioxide gas and 3 mole of water.

Heat combustion of ethanol < Heat combustion of 2,2,4-trimethylpentane
