Answer:

The cylinder is nit on the verge of exploding.

Explanation:

Temperature= 25.0°C

The conversion of T(°C) to T(K) is shown below:

T(K) = T(°C)+ 273.15

So,

T=(25.0 + 273.15) K = 298.15 K

Volume= 4.50 L

Moles= 40.0 mol

Using ideal gas equation as:

PV  = nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is gas constant having value = 0.0821 Latm/ K. mol x 298.15 K

⇔ P= 217.58 atm

Pressure limit = 500 atm .

Answer:

B

Explanation:

Answer:

Option B. It is a basic solution.

Explanation:

To know which option is correct, let us calculate the pH of the solution.

First, we shall determine the pOH of the solution. This is illustrated below:

Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶

pOH =.?

pOH = –Log [OH¯]

pOH = –Log 3.5×10¯⁶

pOH = 5.5

Finally, we shall determine the pH. This can be obtained as follow:

pOH = 5.5

pH =?

pH + pOH = 14

pH + 5.5 = 14

Collect like terms

pH = 14 – 5.5

pH = 8.5

The pH scale reads as follow:

0 to 6 => Acidic

7 => Neutral

8 to 14 => Basic

Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.

Answer:

A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.

Explanation:

Image A shows a loud and low-pitched sound.

The term frequency refers to the number of waves that pass a fixed point in unit time.

High pitched sound is of higher frequency because they make the air molecules vibrate much faster than low-pitched sound. Due to their high frequency, their wavelength is shorter (Remember wavelength and frequency are inversely proportional). Vice versa is true to the low-pitched sound. They vibrate air molecules slower than high-pitched sound. Their wavelength is longer and frequency smaller.

Hence, option A is the correct answer.

Answer:

22.9 Liters CO(g) needed

Explanation:

2CO(g)     +   O₂(g)    =>    2CO₂(g)

? Liters          32.65g

                 = 32.65g/32g/mol

                 =   1.02 moles O₂

Rxn ratio for CO to O₂ = 2 mole CO(g) to 1 mole O₂(g)

∴moles CO(g) needed = 2 x 1.02 moles CO(g) = 2.04 moles CO(g)

Conditions of standard equation* is STP (0°C & 1atm) => 1 mole any gas occupies 22.4 Liters.

∴Volume of CO(g) = 1.02mole x 22.4Liters/mole = 22.9 Liters CO(g) needed

Aluminum sulfate with barium nitrate to produce burin and aluminum nitrate

Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Chemical reactions are essential natural processes that take place and are in charge of the innumerable alterations and transformations we experience every day. They include the forming and breaking of chemical bonds between atoms, which causes the atoms to be rearranged to produce new compounds with various properties. The concepts of mass and energy conservation control chemical processes. The idea of balanced chemical equations came about because the total number of atoms of each element involved in a reaction stays constant both before and after the reaction. Aluminium hydroxide and barium nitrate are produced as a result of the chemical reaction between barium and aluminium nitrate. The reaction's balanced equation is as follows: [tex]2 Al + 3 Ba (NO_3)_3 \rightarrow 3 Ba(NO_3)_2 + 2 Al(OH)_3[/tex]

Answer:

Plants need to regulate the level of water in their bodies in order to be able to carry out several essential processes like photosynthesis and respiration as well as maintain cell turgidity, without which the plant will not survive in its given environment.

Explanation:

The ability of plants to regulate the amount of water in their bodies is known as water balance.

Plants need water in order to carry out many of their essential life functions such as photosynthesis, respiration, nutrition,etc. They also need water in order to order to maintain cell turgidity which serves to support the plant and keep them upright in order for them to absorb sunlight for photosynthesis. Water is also needed in cell division and growth in plants. Without water the plant would not survive, as it would not be able to carry out these essential life processes.

Water balance in plants is maintained through the process of transportation. Transpiration is the process by which water leaves the plant by evaporation through its leaves. When there is an excess of water absorbed by the plant through its root hairs, the rate of transpiration in plant increases. However, when there is little quantity of water available for the plant to use for its cellular processes, the rate of transportation reduces. The opening and closing of the stomata in the leaves of plants regulates the process of transportation.

Answer:

Explanation: This reaction is called a synthesis reaction. This is because a synthesis reaction is when two or more reactants combine/react together to form a single product. The two reactants carbon (C) and oxygen (O2) reacted together to form one single product: carbon dioxide (CO2)

Answer: Heat of reaction

Explanation:

Change in entropy is the difference between the entropy of products and the entropy of reactants.

 Heat of reaction is the energy released or absorbed during the course of the reaction. It is difference between the potential energy of the products and the potential energy of the reactants.

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

Reaction complex is the short lived intermediate formed when reactants are coverted to products.

Answer:

The correct answer is -

1. D. mold

2. A. Cast

3. F. trace fossil

4. C. original material fossils

5. B. fossil record.

Explanation:

Mold is the impression of an organism in a rock that occurs due to the complete dissolving of the organism and only an impression left in sedimentary rocks.

The cast is a fossil copy of an organism in a rock that takes place when water-containing minerals fill the molds and creates a three-dimension copy of the fossil.

Trace fossils are the fossils that are preserved in such a manner that records of biological activity stored only instead of remains of plants or animals.

Storing originals animals or parts of the remaining such as tissue of an organism in natural form is known as original-material fossils.

Fossil records are the fossils ever found or discovered on the earth.

Another type of weathering that attacks rocks is chemical weathering, a process that breaks down rock through chemical changes. The causes of chemical weathering include action of water, oxygen, carbon dioxide, living organisms, and acid rain. Chemical weathering can produce new minerals as it breaks down rock.
