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.

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.

What would be the mass of a 33.5dm3 sample of O2 at STP?
liraira [26]

Answer:

• One mole of oxygen is equivalent to 16 grams.

→ But at STP, 22.4 dm³ are occupied by 1 mole.

{ \tt{22.4 \:  {dm}^{3}   \: \dashrightarrow \: 16 \: grams}} \\  { \tt{33.5 \:  {dm}^{3}  \:  \dashrightarrow \: ( \frac{33.5 \times 16}{22.4} ) \: grams}} \\  \\  \dashrightarrow \: { \boxed{ \tt{23.94 \: g \approx \: 24 \: grams}}}

How much mass is lost through radioactive decay if 1.8 x 1015 Jare.
ser-zykov [4K]

The mass lost through radioactive decay is 0.094 kg.

<h3>What is the mass lost in a radioactive decay?</h3>

The mass loss in a nuclear reaction such as a radioactive decay is known as mass defect.

The lost mass is converted to energy released during the decay process.

The energy and mass are related by the formula:

  • E = mc²

where

m is mass

E is energy

c is speed of light = 3.0 * 10⁸ m/s

Mass lost = E/c²

mass lost = 8.5 * 10¹⁵/(3.0 * 10⁸)²

mass lost = 0.094 kg

Therefore the mass lost is 0.094 kg.
