Answer:True.

As you increase the wavelength the frequency decreases.

Explanation:

The wavelength of a wave is the distance(in meters) between the two consecutive crest and trough of a wave. The S.I unit of the wavelength is meter.

The frequency of a wave is the number of complete wave cycle passing a particular point per second. The S.I unit of the frequency is Hertz.

Wave's frequency and wavelength are related to each other as

Frequency = 1 / Wavelength

As the Frequency is inversely proportional to the wavelength of a wave so as the frequency will increase the wavelength of the wave will decrease and vise-versa.

So, its true that As we increase the wavelength the frequency decreases.

describe the difference between a monoprotic acid and a triprotic acid. How does a triprotic acid generate hydrogen ions?
natita [175]
With the Bronsted-Lowry theory of acids and bases, acids donate protons to other substances. A monoprotic acid is an an acid that can only supply one proton (hydrogen). A triprotic acid is an an acid that can supply up to three protons (hydrogens). A triprotic acid get get its hydrogen ions by receiving them from a base.

A mixture of 0.600 mol of bromine and 1.600 mol of iodine is placed into a rigid 1.000-L container at 350°C. Br2(g) + I2(g) 2IBr
blagie [28]

Answer:

The answer to your question is K = 1.48

Explanation:

Balanced chemical reaction

                   Br₂   +   I₂    ⇒    2IBr

Process

1.- Calculate the concentration of each of the reactants

[Br₂] = 0.6 mol  / 1  L

        = 0.6 M

[I₂] = 1.6 mol / 1 L

     = 1.6 M

[IBr] = 1.19 M

2.- Write the equation of the Equilibrium constant

      K = [IBr]² / [Br₂][I₂]

-Substitution

      K = [1.19]² / [0.6][1.6]

- Simplification

      K = 1.4161 / 0.96

- Result

      K = 1.48

Examine these two MSDS from different manufacturers for sodium hydroxide (NaOH). Compare and contrast the following aspects: che
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.
