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

What is the chemical formula for a compound between Al and F? AlF AlF 3 AlF 2 Al 3F
tester [92]

Answer:

AlF3

Explanation:

Aluminum fluoride (AlF3) is an inorganic compound in which aluminum and fluoride has ionic bond between each other.

Aluminum ( atomic number - 13) has 3 valence electrons and can lose 3 electrons to get a stable configuration while fluorine (atomic number - 9) can gain one electron to make a stable configuration. So in order to attain a stable configuration one aluminum (Al) atom form ionic bond with three fluorine atoms and form AlF3.

Hence, the chemical formula between  Al and F is AlF3.

A 17.0 L helium tank is pressurized to 22.0 atm. When connected to this tank, a balloon will inflate because the pressure inside
mel-nik [20]

Answer:

The volume of the balloon would be 374 L.

Explanation:

Initially, He occuplies a volume of 17.0 L (V₁) at a pressure of 22.0 atm (P₁). If pressure decreases to 1.00 atm (P₂), volume is expected to increase. Assuming ideal behavior of the gas and constant temperature, we can calculate the final volume (V₂) using Boyle's Law.

P_{1} \times V_{1} = P_{2} \times V_{2}\\V_{2} = \frac{P_{1} \times V_{1}}{P_{2}} =\frac{22.0atm \times 17.0L}{1.00atm} = 374 L

Which describes an atom that has fewer neutrons than protons and more electrons than protons?
Eva8 [605]

Answer:

Option d is correct = Negative ion

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg  and 1.674929×10⁻²⁷ Kg  respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The  umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.

When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion. For example,

Anion formation:

X + e⁻ → X⁻

Cation formation:

X → X⁺ + e⁻

Thus option d is correct option.
