A graph of potential energy versus internuclear distance for two Cl atoms is given below. On the same graph, carefully sketch a curve that corresponds to potential energy versus internuclear distance for two Br atoms.

Answers

Answer 1

Answer:

Explanation:

The sketch of the curve for two Br atoms can be seen in the image attached below. From the image below, we can deduce the following:

On the periodic table, the Bromine (Br) atom is the fourth member in the halogen family group. The atomic size increases from top to bottom down the group, thus Br atom posses a larger atomic size than Cl atom. As a result of that, the bond length formation between the two Br atoms will be larger compared to that of the two Cl atoms.

If 700 g of water at 90 °C loses 27 kJ of heat, what is its final temperature?

Answers

Answer:

If 700 g of water at 90 °C loses 27 kJ of heat, its final temperature is 106.125 °C

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

In this way, between heat and temperature there is a direct proportional relationship (Two magnitudes are directly proportional when there is a constant so that when one of the magnitudes increases, the other also increases; and the same happens when either of the two decreases .). The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat and the mass of the body. So, the equation that allows to calculate heat exchanges is:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT is the variation in temperature, ΔT= Tfinal - Tinitial

In this case:

Q= 27 kJ= 27,000 J (being 1 kJ=1,000 J)[tex]c=4.186 \frac{J}{g* C}[/tex]m=700 gΔT= Tfinal - Tinitial= Tfinal - 90 °C

Replacing:

[tex]27,000 J=4.186 \frac{J}{g* C}*400 g* (Tfinal - 90C)\\[/tex]

Solving:

[tex]27,000 J=1,674.4 \frac{J}{C}* (Tfinal - 90C)[/tex]

[tex]\frac{27,000 J}{1,674.4 \frac{J}{C}} =(Tfinal - 90C)[/tex]

16.125 °C= Tfinal - 90 °C

Tfinal= 16.125 °C + 90 °C

Tfinal= 106.125 °C

If 700 g of water at 90 °C loses 27 kJ of heat, its final temperature is 106.125 °C

a car is traveling 35 miles/hr for 17 miles. How much time has the car been on the road?

a
595 hours
b
2.1 hours
c
1.5 hours
d
0.49 hours

Answers

Answer:

The car has been on the road for 0.49 hours

Explanation:

A car is traveling 35 miles/hr for 17 miles.

Speed of a car = 35 miles/hr

Distance travelled = 17 miles

The relationship between speed, distance, and time is given by

Distance = Speed × Time

Put Speed = 35 miles/hr, Distance = 17 miles

[tex]17=35[/tex] × Time

Time = [tex]\frac{17}{35}=0.49[/tex] hours

So, the car has been on the road for 0.49 hours

The time car has been on the road has been 0.49 hours. Thus, option D is correct.

Speed can be defined as the distance traveled by the object in unit time. The speed can be expressed as:

[tex]\rm Speed\;=\;\dfrac{Distance}{Time}[/tex]

The car has been given to be traveling at:

Speed = 35 miles/hr

Distance traveled = 17 miles.

The time taken by car to travel 17 miles can be calculated by substituting the values as:

[tex]\rm 35\;miles/hr\;=\;\dfrac{17\;miles}{Time}\\\\\\\\Time\;=\;\dfrac{17\;miles}{35\;miles/hr}[/tex]

Time = 0.49 hr.

The time taken by car to travel 17 miles has been 0.49 hours. Thus, the correct option has been D.

During which phase does Earth see more than half of the moon's surface? first quarter third quarter waxing gibbous waning crescent

A: Frist quarter
b: third quarter
c: waxing gibbous
d: waning crescent

Answers

Answer:

Explanation:

During the "Third Quarter" phase, Earth sees more than half of the moon's surface. The correct option is B.

What is Waxing Gibbous and Waning Crescent?

Waxing Gibbous and Waning Crescent are two phases of the Moon.

Waxing Gibbous is a phase of the Moon that occurs after the First Quarter phase and before the Full Moon phase. During this phase, the illuminated portion of the Moon is greater than half but less than fully illuminated, meaning it appears to be a "bulging" shape. The term "waxing" means that the illuminated portion of the Moon is increasing in size.

The Waning Crescent is a phase of the Moon that occurs after the Third Quarter phase and before the New Moon phase. During this phase, the illuminated portion of the Moon is less than half and decreasing in size. The term "waning" means that the illuminated portion of the Moon is decreasing in size. The crescent shape refers to the thin sliver of illuminated portion of the Moon that is visible during this phase.

Here in this question,

During the First Quarter phase, the right half of the Moon's surface is visible from Earth.

During the Third Quarter phase, the left half of the Moon's surface is visible from Earth.

During the Waxing Gibbous phase, more than half of the Moon's surface is visible, but Earth does not see more than half.

During the Waning Crescent phase, less than half of the Moon's surface is visible, and Earth does not see more than half.

Therefore, Option B i.e third quarter is correct.
