Answer:

3.052 × 10^24 particles

Explanation:

To get the number of particles (nA) in a substance, we multiply the number of moles of the substance by Avogadro's number (6.02 × 10^23)

The mass of Li2O given in this question is as follows: 151grams.

To convert this mass value to moles, we use;

moles = mass/molar mass

Molar mass of Li2O = 6.9(2) + 16

= 13.8 + 16

= 29.8g/mol

Mole = 151/29.8g

mole = 5.07moles

number of particles (nA) of Li2O = 5.07 × 6.02 × 10^23

= 30.52 × 10^23

= 3.052 × 10^24 particles.

Answer:

The rollercoaster has the lowest kinetic energy at the top of the hill.

The rollercaoster has the highest kinetic energy at the bottom of the hill.

Explanation:

The kinetic energy of any solid body in motion is usually computed using this formula:

K.E = [tex]\frac{1}{2}mv^2[/tex]

From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.

We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.

This means that the variations in the K.E are mainly coming from its velocity.

At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.

However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.

Answer:

70%of 2000 = 1400

2000 tonnes of hematite contains 1400 tonnes iron oxide .

1400 tonnes of fe2O3

fe2O3 have molar mass 159.69

calculate moles = given mass/molar mass

moles = 1400000000/159.69

moles = 8766986

one mole contains = 112 g of fe

so 8766986 moles will contain = 112×8766986

= 981,902,432 grams of ferrous

which is nothing but equal to 981.90 tonnes of iron!!

Answer: 1. The coefficient is 1.12

2. The exponent is 4

3. There are 3 significant digits

4. The rightmost significant figure is 2.

Explanation:

Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example : 5000 is written as [tex]5.0\times 10^3[/tex]

According to avogadro's law, 1 mole of every gas contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles and occupy 22.4 L at STP.

[tex]6.023\times 10^{23}[/tex] molecules of [tex]CO_2[/tex] occupy = 22.4 L at STP.

Thus [tex]3.00\times 10^{26}[/tex] molecules of [tex]CO_2[/tex] occupy = [tex]\frac{22.4}{6.023\times 10^{23}}\times 3.00\times 10^{26}=11.2\times 10^3 L[/tex] at STP.

Scientific notation = [tex]1.12\times 10^4L[/tex]

The coefficient is 1.12

The exponent is 4

There are 3 significant digits

The rightmost significant figure is 2.

Answer:

435.38 L

Explanation:

From the question,

Applying ideal gas equation,

PV = nRT................... Equation 1

Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.

Since Temperature and Pressure were constant,

V ∝ n

V/n = V'/n'.................... Equation 2

Where V and V'  = the initial and final Volume of Ar respectively, n and n'  = the initial and final moles of Ar respectively

make V' the subject of the equation

V' = Vn'/n............... Equation 3

Given: V = 100 L, n = 3.25 mol, n' = 14.15

Substitute into equation 3

V' = (100×14.14)/3.25

V' = 435.38 L

4.15 mole of Ar gas occupy the volume of 435.38 L under same condition.

Ideal gas equation for any gas at standard condition is define as:

PV = nRT, where

P = Pressure,

V = Volume,

n = number of moles,

R = molar gas constant,

T = Temperature.

In the question it is given that pressure and temperature for the expansion is constant, so ideal gas equation becomes:

V/n = V'/n', where

V = initial volume of Ar = 100 L (given)

V' = final Volume of Ar = to find?

n = initial moles of Ar = 3.25 mole (given)

n' = final moles of Ar = 14.15 mole (given)

Now we calculate the final volume as:

V' = (100×14.14)/3.25 = 435.38 L

Hence, 435.38 L is the occupied volume.

Answer:

The alkali metals/group 1 are recognized as a group and family of elements. These elements are metals. Sodium and potassium are examples of elements in this family. Hydrogen is not considered an alkali metal because the gas does not exhibit the typical properties of the group. The largest family of elements consists of transition metals/group 3-12/group 3a. The center of the periodic table contains the transition metals, plus the two rows below the body of the table (lanthanides and actinides) are special transition metals. Even though both are metals, transition metals have higher melting points; they have higher density; they are less reactive with water; they react and form ions with different charges, but Group 1 metals only form 1+ ions.

Explanation:

1 mole of a gas occupies 22.4 L

x moles occupies 16.8 L

x = 1 mole *  16.8 L/22.4 L

x = 0.75 moles

number of moles = mass/molar mass

mass =  number of moles  * molar mass

mass =  0.75 moles * 30.01 g/mol = 22.5075 g = 2.25 * 10^1 g
