Answer:

C4H10 has a higher boiling point due to stronger dispersion forces

1-butanol has the greater boiling point mainly due to hydrogen bonding influences

Explanation:

If we consider propane and n-butane, we discover that they are both alkanes. However, the magnitude of dispersion forces in alkanes depends on the length of the carbon chain. The greater the length of the carbon chain is greater in n-butane than in propane. The greater the chain length, the greater the magnitude of dispersion forces and the greater the boiling point. Hence, n-butane has a higher boiling point than than propane.

Also, if we compare the boiling points of 1-butanol to that of diethyl ether, we will discover that 1-butanol has a higher boiling point mainly due to intermolecular hydrogen bonding influences.

Answer: the answer is B

Explanation:

Answer:

Savanna regions have two distinct seasons - a wet season and a dry season. There is very little rain in the dry season. In the wet season vegetation grows, including lush green grasses and wooded areas.

Savannas are grasslands found in Africa, Australia, South America, and India. The climate is warm or hot. Savannas experience both dry and rainy seasons. Each year, savannas receive about 20 to 50 inches of rain in a span of six to eight months. The other months are dryer. There’s also a threat of wildfires because of the severe dryness during these months. Grasslands are true to their name because their vegetation is mostly grass. Savannas are home to a wide range of animals, including different species of beetles and insects, which many creatures consume. Squirrels, mice, elephants, gazelles, and antelopes are the plant-eating animals that live in the savanna. Hyenas, lions, and leopards are some of the meat-eating animals in these areas. Some of the nonliving components of the system include very porous soil that allows water to drain easily.

Explanation:

The end product of Photosynthesis is glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Answer:

Add to a 500mL volumetric flask 300mL of water, the 129mL of the 11.6M HCl solution and then complete to volume with water

Explanation:

To make 500mL = 0.500L of a 3M HCl from the 11.6M HCl stock we need first to find the moles of HCl we need:

Moles HCl:

0.500L * (3mol / L) = 1.5 moles of HCl are needed

These moles are obtained from the 11.6M HCl solution. The volume required is:

1.5mol * (1L / 11.6moles HCl) = 0.129L = 129mL must be added to the solution.

That means to prepare the 500mL of the 3M HCl you need to:

Add to a 500mL volumetric flask 300mL of water, the 129mL of the 11.6M HCl solution and then complete to volume with water

Answer:

Calculation: 11.6 M × V = 3.0 M × 0.500 liters

V = 0.13 liters

Steps for dilution:

Measure out 0.13 liters of the concentrated solution of 11.6 M HCl using a volumetric pipet.

Transfer this into solution into a 500 milliliter volumetric flask.

Add water to the flask until it reaches a total volume of 500 milliliters.

Solution: V = 0.13 liters

Answer:

False.

Explanation:

(5 kilometers / 30 minutes), you could then say that in 60 minutes (one hour) you would be traveling at (10 kilometers / 60 minutes)...

Therefore, it is unlikely that you would be traveling at (6 kilometers / hour), so the answer should be... False.

Answer:

Explanation:

From the information above:

The equation for the reactor volume of CSTR is given by the formula:

[tex]V = \dfrac{C_{Ao}V_o - C_A V_o }{-rA}[/tex]

[tex]V = \dfrac{C_{Ao}V_o (1 - 0.01)}{KC_A^2}[/tex]

The reaction rate of A is:

[tex]-r_A = kC_A^2[/tex] and k = 3 dm³/mol.h

replacing the values in the above equation to solve for v;

∴

[tex]V = \dfrac{(0.5 \ mol/dm^3) (10 \ dm^3/h) (1 - 0.01)}{ ( 3 \ dm^3/mol.h) (0.01 \times 0.5 \ mol/dm^3)^2}[/tex]

V = 66,000 dm³

Thus, the reactor volume of CSTR is 66000 dm³

Taking the differential mole balance equation for PFR is as follows:

[tex]\dfrac{d(C_AV_o)}{dV} = -r_A[/tex]

[tex]\dfrac{d(C_AV_o)}{dV} = Kc^2A[/tex]

Taking the integral between initial and final concentrations;

[tex]\dfrac{v_o}{k} \int ^{C_A}_{C_{Ao}} \dfrac{dC_A}{C^2A}= - \int ^V_o \ dV[/tex]

[tex]V = \dfrac{V_o}{K} \Big [\dfrac{1}{C_A}- \dfrac{1}{C_{Ao}} \Big ][/tex]

replace the values in the above equation;

[tex]V= \dfrac{(10 \ dm^3/h) }{(3 \ dm^3/mol.h)}\Big [ \dfrac{1}{0.01(0.5 \ mol/dm^3)} - \dfrac{1}{0.5 \ mol/dm^3} \Big ][/tex]

[tex]\mathbf{V = 66 0 \ dm^3}[/tex]

Thus, the reactor volume of PFR is 660 dm³

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.

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:

shorter bond, because charges are close apart

Explanation:

shorter the bond length more is the energy required to break the bond for example if you take three pencils of different sizes one longer One medium sized One Shot sized if you try to break them the longer pencil will break much faster than the other two because the greater the length the lesser the strength the lesser energy you need to apply to break them apart ...
