The statement which is true about both groundwater and surface water is that the  groundwater and the surface water together form a drainage basin​.

Ground water is the type of water which is present below the surface of rock and between spaces in soil pores .Thirty percent of the available fresh water is present in the form of groundwater.

Groundwater is discharged from the surface naturally in the form of springs and seeps and can also exist in the form of oases or wetlands.It is used for various purposes like for agriculture, municipal and industrial uses. They are used by constructing wells .

The study of movement and distribution of ground water is called hydrogeology or even groundwater hydrology.It is a cheaper source of water and is less prone to pollution as compared to surface water.

Explanation:

Hello!

In this case, since we know the concentration in the medication:

[tex]\frac{350.0\mu g}{1mL}[/tex]

Now, since there are 0.50 mg of the medication per kilogram of patient, we can compute the volume as shown below for a 183-lb patient:

[tex]183lb*\frac{1kg}{2.204lb}* \frac{0.50mg}{1kg} *\frac{1000\mu g}{1mg} *\frac{1mL}{350.0\mu g} =118.61mL[/tex]

Explanation:

Answer:

The correct answer is - option D.  the boiling point of solution A will be lower than the boiling point of solution B

Explanation:

Colligative properties such as a decrease in the freezing point of the solution, increase in the boiling point of substance, decrease in Lowering of vapor pressure, and other properties depend upon the number of molecules only.

In the given solution the equal amount of two solutions are mixed that is 50 grams however due to the difference in the molecular mass so the atoms present in both solution A and B will be different. It is known that the number of atoms of a substance is inversely proportional to the molecular mass of the particular substance.

As it is given that Solution B has a low molecular mass which means it has a high number of atoms that means its boiling point will be higher than solution A.

Answer:

The active sites on the initial amount of catalyst were fully saturated

Explanation:

A catalyst is a substance which alters the rate of a chemical reaction but largely remains unaltered at the end of the reaction. A catalyst has an active site which enables it to catalyze a reaction.

The active site provides the best possible orientation for reactant molecules to collide in order to form products.

When the active sites are not fully saturated with reactant molecules, more reactant molecules can bind and the reaction can proceed much faster. However, if the active sites of the catalysts are fully saturated, the reaction has maximum velocity and cannot go anymore faster.

Addition of more catalyst molecules can however make the reaction proceed faster as a it provides more active sites for reaction for the reactants.

Answer:

Magenta.

Explanation:

Color absorption is a process that occurs when a light wave strikes an object. When a light wave strikes an object it either absorbs color or transmits the color, or reflects the color. When a light wave strikes a green object, it absorbs a magenta color.

Magenta is a combination of red and blue light, therefore, the colors that the green object will absorb is red. blue, or magenta light.

Answer:

b. tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

Explanation:

Entropy can be defined as the tendency for a substance to achieve maximum disorder (i.e., randomly distribute).

This ultimately implies that, entropy is a thermodynamic quantity that measures the degree of maximum order or randomness of a system.

The S.I unit used for the measurement of the degree of maximum order or randomness of a system is Joules per Kelvin (JK¯¹). An example of entropy is the mixing of ideal gases.

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

mol = mass : molar mass

mass = mol x molar mass

Molar mass = 58,6934 g/mol

Input the value :

mass = 0.0321 x 58,6934 g/mol

mass = 1.884 g

Answer:

0.2mol/dm³

Explanation:

Given parameters:

Mass of Na₂CO₃   = 10.6g

Volume of solution  = 500mL

Unknown:

Molarity of solution  = ?

Solution:

The molarity of a solution can be determined using the expression below:

 Molarity = [tex]\frac{number of moles }{volume}[/tex]  

     Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16)  = 106g/mol

   Number of moles  = [tex]\frac{10.6}{106}[/tex]   = 0.1mol

   Convert mL to dm³;

        500mL will give 500 x 10⁻³dm³or 0.5dm³  

So;

Molarity  = [tex]\frac{0.1}{0.5}[/tex]    = 0.2mol/dm³

Answer:

16.8 L

Explanation:

From the question given above, the following data were obtained:

Number of mole of He = 0.750 mole

Volume of He =?

Recall:

1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.

Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:

1 mole of He occupied 22.4 L at STP.

Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.

Thus, 0.750 mole of He is equivalent to 16.8 L

The question is incomplete, the complete question is;

Suppose 1.87g of nickel(II) bromide is dissolved in 200.mL of a 52.0mM aqueous solution of potassium carbonate. Calculate the final molarity of nickel(II) cation in the solution. You can assume the volume of the solution doesn't change when the nickel(II) bromide is dissolved in it. Be sure your answer has the correct number of significant digits. The answer is needed in M.

Answer:

0.0428 M

Explanation:

The equation of the reaction is;

NiBr2 + K2CO3 → NiCO3 + 2KBr

Number of moles of NiBr2 = mass/molar mass = 1.87 g/218.53 g/mol =

8.557 *  10^-3 moles

Now, we know that the Ni^2+ comes from the NiBr2. Also, the concentration of Ni^2+ in NiBr2 = concentration of Ni^2+ in NiCO3

So,

Concentration of Ni^2+ = 8.557 *  10^-3 moles/0.2 L = 0.0428 M

Answer:

2.03

Explanation:

Let's assume we have 1 L of the solution:

With that information we can calculate the molality:

Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.

The molality of an ethylene glycol solution is 2.03 kg.

The moles of solute divided by the mass of solvent in kilograms is known as the molality of a solution.

Calculation of molality:

Given that, molarity is 2.07 M

Density is 1.02 g/ml

Step 1: To convert  the litre into grams, multiply the quantity by 1000

The weight of the solution is [tex]\bold{1.02 \;g/ml\; \times 1000 = 1020 g}[/tex]

Now, molality = moles of solute is divided by mass of solvent in kilograms.

[tex]\bold{Molality = 2.07 \times \dfrac{1020}{1000} = 2.03\; kg}[/tex]

Thus, the molality of the solution is 2.03 kg

https://brainly.com/question/4580605

   molality = moles of solute / kg of solvent

   molality = 2.07 moles / (1020 ÷ 1000) = 2.03 m

Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.
