Conditions to Avoid: Natural gas is extremely flammable and explosive; avoid heat, sparks, open flames, and all possible sources of ignition. Heat will increase pressure in containers used to store natural gas.Jun 1, 2015

Answer:

Natural Gas can be explosive or flammable depending on it's concentration in air.  

Natural gas has a flammability range of approximately 5 to 15 percent.

Any percentage greater than that is explosive for natural gas.

Hope this helps.

Answer:

Hydrogen bromide, anhydrous appears as a colorless gas with a pungent irritating odor. Corrosive. Heavier than air. Prolonged exposure to fire or intense heat may result in the violent rupture and rocketing of the container. Long-term exposure to low concentrations or short-term exposure to high concentrations can result in adverse health effects from inhalation. Used to make other chemicals and as a catalyst in the manufacture of chemicals. Rate of onset: Immediate Persistence: Minutes to hours Odor threshold: 2 ppm Source/use/other hazard: Chemical manufacturing industry; very corrosive.

Answer: A saturated solution, by definition, contains an amount of solute equal to the amount of dissolved solute in equilibrium with an undissolved solute. We could, however, make a supersaturated solution in which the solvent contains more solute than would be in equilibrium with undissolved.

Explanation:   More solute cannot be dissolved at a given temperature in a saturated solution. This is because the solute dissolves in a solvent due to the space between the solvent particles, but with the continuous addition of solute, the space between the solvent particles is filled. As a result, no more solute particles can dissolve in the solvent.

saturated

Boyle's law :-  the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.

Boyle's law can also be formularized as P1V1 = P2V2

Charle's law :-  the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

Charle's law can also be formularized as V1/T1 = V2/T2

Answer:

A = Base x Height, Volume = Length x Width x Height

Answer:

Acid is a molecule capable of donating hydrogen ion and they form aqueous solutions with a sour taste while base is a substance that accepts proton from proton donor and in aqueous solution, they have an astringent or bitter taste. Moreover, a good example for base is sodium hydrogen carbonate as baking soda or baking powder and for acid, the most common example is the acetic acid or vinegar.

Answer:

Well, for starters, bases mostly consist of soaps and cleaning products, acids consist of vinegar,lemon,and stuff like that. Most acids on the basis of touch can burn your skin or be very sour, unlike bases which are more soapy and have a cleaner touch.A good example of an acid is vinegar, which can be used for cleaning but can also be used for making foods, on the other hand. A good example of a base is dish soap. It is used for cleaning.

Helium is a noble gas with a stable electronic configuration. It differs from other elements in group 18 as it has two valence electrons, while the rest of them has 8 valence electrons. Thus, option a is correct.

Helium is a noble gas or inert gas placed in group 18 of the periodic table with atomic number 2. It is an s-block element as its valence electron lies in the s- subshell. Its configuration is,

He (2) ⇒ 1s²

The other elements of the group include neon, krypton, radon, xenon, and argon which have eight valence electrons in their outermost shell of the atom that completes their octet and makes them stable.

Therefore, option a. the helium differs from the other noble gas of the same group as it has two valence electrons while others have eight valence electrons.

Answer:

[tex]\boxed {\boxed {\sf 3. \ GAGCTC}}[/tex]

Explanation:

Amino acids are the monomers or building blocks of protein. Proteins are created during protein synthesis according to the genetic information or DNA in an organism.

The DNA is translated to messenger RNA in the nucleus. It travels to the ribosome. There, the mRNA is "read off" in threes. Three nucleotides make up  a codon. Transfer RNA with the corresponding anticodon and an amino acid attaches to the codon and a chain of amino acid forms.

If 3 nucleotides make 1 codon which makes 1 amino acid, then we need double that or 6 nucleotides to make 2 amino acids.

The only answer choice with 6 nucleotides is Choice 3: GAGCTC

Answer:

Electrons can have a measured radius.

Electrons do not have energy, the energy is determined by the orbit.

Explanation:

because I have got it right.

The correct answer is, "Electrons do not have energy, the energy is determined by the orbit."

In the Bohr model of the atom, electrons are arranged in energy levels. The energy of an electron is determined by the energy level in which it is found.

When electron an the  electron moves from a lower to a higher energy level it absorbs energy. When the electron moves from a higher to a lower energy level, it radiates energy. This energy is observed in the form of visible light.

Thus, in the Bohr's model, electrons are arranged in energy levels. The energy level where an electron is found determines its energy.

The volume of the liquid from the graduated cylinder is 22.5 mL

The last option (22.5 mL) is the correct option

The question seems to be incomplete

The image that completes the question is shown in the attachment below.

From the image, we observe that the liquid meniscus is between the 20 mL and 25 mL marks. That means the volume will lie in this range.

NOTE: The meniscus of a liquid is the upward or downward curve seen at the top of a liquid in a container.

The type of curve shown in the image is a concave meniscus and the volume of the liquid is read from the bottom of the curve.

To read the value from the graduated cylinder, we will first determine the difference between two consecutive lines. Between the 20 mL and 25 mL mark (two thick lines), we have 5 spaces separated by thin lines.

The measure between two consecutive lines is the difference between two thick lines divided by number of spaces between them

∴ The measure between two consecutive lines = (25mL - 20mL) ÷ 5

The measure between two consecutive lines = 5mL ÷ 5 = 1 mL

Now, to read the position of the liquid,

Starting from the 20 mL mark, the liquid exceeds two more lines + half way to the next line ( that is 2mL + 0.5 mL)

∴ The position of the liquid is 20 mL + 2mL + 0.5 mL = 22.5 mL

Hence, the volume of the liquid from the graduated cylinder is 22.5 mL

Aromatic compounds are compounds that contain carbon-carbon multiple bonds.

The question did not mention that a heteroatom is present in the compound so we can assume that there is none of such. In that case, the compound contains only hydrogen and carbon.

So,

(CH)n = 78

where n is the number of each atom present.

(12 +1)n = 78

n = 78/13

n = 6

The molecular formula of the compound is C6H6

When C6H6 is treated with .conc.HNO3/conc.H2SO4 the compound shown in image 1 is formed. The reaction occurs at the C-C multiple bond.

When C6H6 is reacted with chlorine in the presence of sunlight, hexachlorobenzene (shown in image 2 attached) is formed.

Why is the unit of force called a derived unit? That's because the Newton is defined in terms of other units which are more fundamental. One Newton is the force required to accelerate a mass of one kilogramme at the rate of one metre per second squared.
