Answer:

Mineral water> Bitter gourd juice> Orange juice> Hydrochloric acid

Explanation:

pH is referred to as the degree of acidity or alkalinity of a substance. The pH scale is arranged from 0-14. Substance with a pH of 0-6.9 are acid, a pH of 7 indicates neutrality while a pH of 8-14 indicates alkalinity.

Mineral water is usually slightly acidic with a pH between 5-6. The pH of bitter gourd juice is between 4.24-4.45. The pH of orange juice ranges between 3.3 to 4.2 lastly, the pH of hydrochloric acid is about 3.01.

The pH values itemized above informed the arrangement of decreasing pH values shown in the answer box.

Answer:D

Explanation:

The claim about cats is most likely based on science is Genetic data show that modern domestic cats are related to Near Eastern wildcats. The correct option is D.

A claim is a statement that is given by a person about his or her things, and they claim that the thing. It gives proof that a thing or house is a person's property.

Genetic data is the data of the genetic sequence of a person's genetic information. It is different for every person. So genetic data is very important.

So the scientific data will be the genetic data of cats that is claiming that domestic cats are related to Near Eastern wildcats. It is most likely a scientific claim.

Thus, the correct option is D. Genetic data show that modern domestic cats are related to Near Eastern wildcats.

Answer: D convection currents

Explanation:

The seafloor spreading is a phenomena that occurs due to liberation of heat from the convection currents generated in the mantle. It makes the earth crust more plastic and less dense. This happens at divergent plate boundaries. As the plates move apart, the less denser material rises. It leads to the formation of mountain and crust cracks.

Answer : The original volume of gas is [tex]365cm^3[/tex]

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 800 torr

[tex]P_2[/tex] = final pressure of gas at STP = 760 torr

[tex]V_1[/tex] = initial volume of gas = ?

[tex]V_2[/tex] = final volume of gas at STP = [tex]450.0cm^3[/tex]

[tex]T_1[/tex] = initial temperature of gas = [tex]-40^oC=273+(-40) =233K[/tex]

[tex]T_2[/tex] = final temperature of gas at STP = [tex]0^oC=273+0=273K[/tex]

Now put all the given values in the above equation, we get:

[tex]\frac{800torr\times V_1}{233K}=\frac{760torr\times 450.0cm^3}{273K}[/tex]

[tex]V_1= 364.8cm^3\approx 365cm^3[/tex]

Therefore, the original volume of gas is [tex]365cm^3[/tex]

Answer: [tex]Zn+2Ag^+\rightarrow Zn^{2+}+2Ag[/tex]

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously and the number of electrons lost is equal to the number of electrons gained.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Anode : [tex]Zn\rightarrow Zn^{2+}+2e^-[/tex]

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Cathode : [tex]2Ag^++2e^-\rightarrow 2Ag[/tex]

Thus the complete ionic equation will be :

[tex]Zn+2Ag^+\rightarrow Zn^{2+}+2Ag[/tex]

SO₃ is an empirical formula for S₂O₆ and the correct option is option C.

The empirical formula of a compound represents the simplest, most reduced ratio of the atoms present in the compound. It shows the relative number of atoms of each element in the compound, without indicating the actual number of atoms. In other words, it gives the simplest whole number ratio of the elements in a compound.

To determine the empirical formula, the relative amounts of each element in the compound are expressed in terms of moles or mass. Then, the ratios of the moles or masses are simplified to their lowest whole number values.

Thus, the ideal selection is option C.

Explanation:

Answer:

A). Collapse, condensation, accretion, clearing.

Explanation:

Planetesimals are described as the small solid astronomical objects which are the building blocks for the formation of solid planets. Accretion is described as the process in which the solid astronomical objects cluster to form larger objects that eventually leads to the formation of planets.

As per the question, the correct order of processes that are followed in this accretion process would be a collapse, condensation, accretion, clearing. First occurs the collapse of a nebula followed by condensation of cosmic dust grains. After this, the accession or accumulation of solid parts takes place to form larger objects and this is immediately followed by the clearing of debris and dust to allow planets to form. Thus, option A is the correct answer.

Answer:

ΔT = 0.116 °C

Explanation:

Using Formula

Q = mc ΔT

Where Q = 0.360, c = 4.184 and m = 0.7402

ΔT = Q/mc

ΔT = 0.360/ (4.184)(0.7402)

ΔT = 0.360 / 3.097

ΔT = 0.116 °C

So, The change in Temperature/Increase in Temperature is 0.116 °C

Answer:

m = 50.74 kg

Explanation:

We have,

Initial temperature of water is 20 degrees Celsius

Final temperature of water is 46.6 degrees Celsius

Heat absorbed is 5650 J

It is required to find the mass of the sample. The heat absorbed is given by the formula ad follows :

[tex]Q=mc\Delta T[/tex]

c is specific heat of water, c = 4.186 J/g°C

So,

[tex]m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{5650}{4.186\times (46.6-20)}\\\\m=50.74\ kg[/tex]

So, the mass of the sample is 50.74 kg.

Answer:

Explanation:

Temperature: increasing the Temperature increases the solubality

Polarity: increase of polarity increases the soluablity of polar solutes

The larger the molecules of the solute are, the larger is their molecular weight and their size. It is more difficult it is for solvent molecules to surround bigger molecules.

For majority of solid and liquid  solutes, pressure does not affect solubility. it is applciaable only for gasesous solute
