7 0

Answer:

<h2>8.13 mL</h2>

Explanation:

The required volume can be found by using the formula for Boyle's law

V_2 =  \frac{P_1V_1}{P_2}  \\

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

V_2 =  \frac{6.5 \times 1.25}{1}  = 6.5 \times 1.25 \\  = 8.125

We have the final answer as

<h3>8.13 mL</h3>

Hope this helps you

SCORPION-xisa [38]

Answer:

In #1) Chemical Name: Sodium hydroxide, Chemical Formula: Na OH, Synonyms: Caustic soda, Sodium hydrate. General: Corrosive to metals and tissue. Noncombustible solid. Soluble in water. When in contact with water, may generate sufficient heat to ignite combustible materials.Health Hazard: Strong corrosive action on contacted skin. Causes eye and skin burns. Causes digestive and respiratory tract burns. Reactivity: Water, acids, flammable liquids, metals such as aluminum, tin, and zinc.Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider the material's impact on air quality, potential migration in soil or water, effects on animal and plant life, and conformance with environmental and public health regulations.  

#2) Product Name: Sodium hydroxide, pellets

Chemical Name: Sodium Hydroxide

Synonyms: Lye, Caustic soda, Soda lye

G H S-US

Signal Word: Danger

Hazard Statement: H 314 - Causes severe skin burns and eye damage

Precautionary Statements:

P 260 - Do not breathe mist, spray, or vapors.

P 264 - Wash exposed skin thoroughly after handling.

P 280 - Wear eye protection, face protection, protective clothing, and protective gloves.

P 301+P 330+P 331 - IF SWALLOWED: Rinse mouth. Do NOT induce vomiting.

P 303+P 361+P 353 - IF ON SKIN: Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower.

P 305+P 351+P 338 – IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing

P 310 - Immediately call a poison center or doctor/physician.

P 363 - Wash contaminated clothing before reuse.

P 405 - Store locked up.

P 501 - Dispose of contents/container to comply with local, state, and federal regulations

IF INHALED: Remove person to fresh air and keep comfortable for breathing

Health Hazard: Causes severe burns to eyes, skin, and mucus membranes.

Target Organs: Eyes, skin, respiratory system

Hazard Summary: When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive.

Waste Disposal: Waste must be disposed of in accordance with federal, state, and local environmental control regulations.

Which statement correctly compares barium nitrate (Ba(NO3)2) and scandium nitrate (Sc(NO3)3)?
3241004551 [841]
<h2>D. They contain the same number of elements.</h2>

Explanation:

The formula (Ba(NO3)2) contains 9 atoms.  

1 Barium atom (Ba)

Contains 2 NO3 groups -

    2 Nitrogen atoms (N) x 2

    6 Oxygen atoms (O3) x 2

3 Elements in total

The formula (Sc(NO3)3) contains 13 atoms.

1 Scandium atom (Sc)

Contains 3 NO3 groups -

    3 Nitrogen atoms (N) x 3

    9 Oxygen atoms (O3) x 3

3 Elements in total

They do not have the same number of atoms.

They do not have the same number of oxygen atoms.

They do not contain the same number of NO3 groups.

They do have the same number of elements.
