Which element in row 6 of the periodic table (shown below) has the largest radius?

Select one:
a. Hg
b. Cs
c. Os
d. Rn

Answer:

the speed will increase and so will the acceleration. then after a bit the acceleration will decrease due to air resistance until there is no acceleration. Then the speed will continue to decrease when there is no acceleration anymore.

Answer: Crystals differ in physical properties, i.e., in hardness, cleavage, optical properties, heat conductivity, and electrical conductivity.

These properties are important since they sometimes determine the use to which the crystals are put in industry.

hope this helps :)

Answer:

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

Answer:

Detail is given below.

Explanation:

Each element have a specific number of valence electron. We can easily find out the number of valence electron in an atom through electronic configuration. The electrons reside in outer orbital are called valence electrons. It is also equal to the main group number of that element. Consider the example,

Sodium is present in group one thus it has 1 valence electron.

Electronic configuration of sodium:

Na₁₁ = 1s² 2s² 2p⁶ 3s¹

Let consider the example of halogens they are present in group 7A thus they have seven valence electrons.

Electronic configuration of fluorine:

F₉ = 1s² 2s² 2p⁵

The outer orbital contain seven electrons thus these are valance electron.

Copper is present in group 2B thus it must have two valence electrons.

Let check this from electronic configuration.

Cu₂₉ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁹

The outer most orbital is 4s² and it has two electron thus number of valence electron in copper are 2.

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.

Explanation:

According to Avogadro's number, there are 1.204 × 10²³ atoms in 39.39 g of gold.

To determine the number of atoms in 39.39 g of gold, we need to use the Avogadro's number, which is equal to 6.022 × 10²³ atoms/mol.

First,  need to convert the given mass from grams to moles by dividing it by the molar mass of gold, which is 196.967 g/mol.

[tex]\dfrac{39.39}{196.96}\\=0.19999[/tex] moles

Now, we can use Avogadro's number to find the number of atoms:

[tex]0.19999\times6.023\tims10^2^3\\=1.204\times10^2^3[/tex]

Therefore, the prospector has 1.204 × 10²³ atoms of gold.

The human eye can only see white visible light and it contains all the colors of the rainbow, from red to violet.

Explanation:

But visable light comes in many "colors" such as radio, infrared, ultraviolet, X-ray, and gamma-ray that are invisible to the naked eye.The reason that the human eye can see the spectrum is because those specific wavelengths stimulate the retina in the human eye.

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:

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

Answer:

D. Fishing.

Explanation:

Fishing refers to an activity which typically involves catching fishes for both recreational (sports or hobby) and industrial (feeding or sales) purposes. In finishing, the fishes are caught from water such as a pool, lake, river etc. through the use of fishing nets, rod and lines and fish hooks.

Basically, when fishing is done with family members, peers or even individually such as on a vacation, sports competition and pleasure, it is mainly considered to be for recreational purposes.

However, when fishing is done on a commercial basis such as selling them consumers, it is considered to be for industrial purposes.

Hence, fishing is an activity which uses water for both recreational and industrial purposes.

Answer:

Explanation:

one mole of AgNO₃ reacts to inactivate one mole of enzyme

mg of enzyme in 10 mL = 3.4 x 10 mg = 34 mg .

required AgNO₃ = .134 x 10⁻⁶ mole

.134 x 10⁻⁶ mole AgNO₃ is required for inactivating 34 mg of enzyme

1 mole of AgNO₃ will be  required for inactivating 34 / (.134 x 10⁻⁶ ) mg of enzyme

= 253.73 x 10⁶ mg of enzyme

= 253.73 x 10³ g of enzyme

Mol weight of enzyme =  253.73 x 10³ .
