5. The sphere shown below is placed in a full overflow cup and sinks to the bottom. How much water is displaced by the sphere?
4.6 cm
O A. 51.0 ml
OB. 66.5 ml
O C. 88.6 mL
O D.407.7 ml

Answers

Answer : The correct option is (A) 51.0 mL

Explanation :

As we know that water displaced is equal to the volume of sphere.

Now we have to determine the volume of sphere.

Formula used:

Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]

where,

r = radius of sphere

Given:

Diameter of sphere = 4.6 cm

Radius of sphere = [tex]\frac{Diameter}{2}=\frac{4.6cm}{2}=2.3cm[/tex]

So,

Volume of sphere = [tex]\frac{4}{3}\times 3.14\times (2.3cm)^3[/tex]

Volume of sphere = [tex]50.94cm^3\approx 51.0 cm^3[/tex]

Water displaced = Volume of sphere = [tex]51.0 cm^3[/tex]

We know that:

[tex]1cm^3=1mL[/tex]

So,

Water displaced = 51.0 mL

Therefore, the correct option is (A) 51.0 mL

Answer:

A. 51.0 mL

Explanation:

i did this question in my quiz :)

A gas in a large syringe has a volume of 300ml at 45°C. The temperature is lowered to 30°C. What is the new volume of the gas in the syringe? (N and p are constant). Hint:Convert temperature to kelvin before calculating (°C+273=K)

Answers

Answer:

V1=300ml

V2= x ml

T1= 45 Celsius

T2= 30 celcius

Do the math....

you will get

318x=90900

divide by 318

x=285.8 ml (rounded)

Explanation:

you have to add 45 and 30 (separately because the temp. has to be in kelvin) to 273... so V2 equals 2858.8 ml

Sort each of the following elements by effective nuclear charge, Zeff, from smallest to largest:
Sn, Rb, Sb, In, and Sr​

Answers

Answer:

Rb = +1 , Sr = +2, In= +3,  Sn = +4, Sb= +5

Explanation:

Formula:

Zeff = Z - S

Z = atomic number

S = number of core shell or inner shell electrons

For Sn:

Electronic configuration:

Sn₅₀ = [Kr] 4d¹⁰ 5s² 5p²

Zeff = Z - S

Zeff = 50 - 46

Zeff = +4

For Rb:

Electronic configuration:

Rb₃₇ = [Kr] 5s¹

Zeff = Z - S

Zeff = 37 - 36

Zeff = +1

For Sb:

Electronic configuration:

Sb₅₁ = [Kr] 4d¹⁰ 5s² 5p³

Zeff = Z - S

Zeff = 51 - 46

Zeff = +5

For In:

Electronic configuration:

In₄₉ = [Kr] 4d¹⁰ 5s² 5p¹

Zeff = Z - S

Zeff = 49 - 46

Zeff = +3

For Sr:

Electronic configuration:

Sr₃₈= [Kr]  5s²

Zeff = Z - S

Zeff = 38 - 36

Zeff = +2

Which of the following describes a nonmetal
A:brittle shiny and solid at room temperature
B:brittle dull and low density
C:malleable shiny and able to conduct electricity
D:malleable dull and solid liquid or gas at room temperature

Answers

Answer:

b is the answer

Explanation:

non metals are not shiny, brittle, unmalleable, and are poor conductors of thermal energy and electrical current.

A nonmetal is brittle, dull, and low in density.  

Non-metals refer to the elements that produce negative ions by gaining or accepting electrons. The non-metals generally possess 4, 5, 6, or 7 electrons in their valence shell. The non-metals are those, which are devoid of all the metallic properties.  

• The non-metals in their solids-state are brittle, thus, they lack ductility and malleability exhibited by the metals.  

• The non-metals are not shiny like metals, they are dull in color.  

• The non-metals seem to possess low density, primarily as non-metals seem to prevail either in a liquid or solid-state. The non-metals lack the dense and closed packing in the lattice, which is seen in metals.  

Thus, non-metals are brittle, dull, and low in density.

How many atoms are in 3.2 pg of Ca? The molar mass of Ca is 40.08
g/mol.

Answers

Answer:

4.81×10¹⁰ atoms.

Explanation:

We'll begin by converting 3.2 pg to Ca to grams (g). This can be obtained as follow:

1 pg = 1×10¯¹² g

Therefore,

3.2 pg = 3.2 pg × 1×10¯¹² g / 1 pg

3.2 pg = 3.2×10¯¹² g

Therefore, 3.2 pg is equivalent to 3.2×10¯¹² g

Next, we shall determine the number of mole in 3.2×10¯¹² g of Ca. This can be obtained as follow:

Mass of Ca = 3.2×10¯¹² g

Molar mass of Ca = 40.08 g/mol

Mole of ca=.?

Mole = mass /molar mass

Mole of Ca = 3.2×10¯¹² / 40.08

Mole of Ca = 7.98×10¯¹⁴ mole.

Finally, we shall determine the number of atoms present in 7.98×10¯¹⁴ mole of Ca. This can be obtained as illustrated below:

From Avogadro's hypothesis,

1 mole of Ca contains 6.02×10²³ atoms.

Therefore, 7.98×10¯¹⁴ mole of Ca will contain = 7.98×10¯¹⁴ × 6.02×10²³ = 4.81×10¹⁰ atoms.

Therefore, 3.2 pg of Ca contains 4.81×10¹⁰ atoms.

How many moles of Te are present in 100.00 g of the compound?​

Answers

Answer:

The correct answer is 0.22 mol Te.

Explanation:

First, we have to calculate the mass of Te in the sample. We simply multiply the sample mass by the percentage of Te (28.53%= 28.53/100)

100.00 g x 28.53/100 = 28.53 g Te

The molar mass of Te is 127.60 g. Thus, the mass of 1 mol of Te is 127.60 g. With this, we calculate how many moles of Te there are in 28.53 g of Te:

28.53 g Te x 1 mol Te/127.60 g Te= 0.223 mol ≅ 0.22 mol

Answers

Acceleration is force. It can either be Acceleration or Velocity. But go with whichever you think you should:) ( first mind is your best mind)

The size or strength of something like a force is acceleration. Thus, option b is correct.

What is force?

In general language we can say that push or pull is called force.

According,to newton second law of motion force is rate change of momentum it means

F= d/dt×(mxv)

Where m is mass and v is velocity

But in general case mass is constant.

So ,Force

F= mxd/dt×(v)

Since we know that rate change of velocity is acceleration.

Then we can say that

F= mass x acceleration

S.I unit of force is Newton

1 Newton = 1kg×m/sec^2.

Force and acceleration is a physical quantity which have both i.e magnitude and direct it means both are vector quantity. According,to newton second law of motion force is rate change of momentum it means

F= d/dt×(mxv)
