Answer:

protons in the nucleus

Answer:

7.21 x 103 kg/m3

Explanation:

Dimensional analysis has been the process to establish and convert the various units in the measurement. The density of manganese in kg/m3 is 7.21 × 10³ kg/m³.

Dimensional analysis has been the method that is also referred to as the unit factor or factor label method. It solves the mathematical expressions by multiplying the given value with another without changing its quantity and amount. It is used to change the units of the value.

Given,

Density of manganese = 7.21 g/cm³

The dimensional analysis method is used to convert grams per cubic centimeter into kilograms per cubic meter as:

1 gram / cubic centimeter = 1000 kilogram / cubic meter

So, 7.21 g/cm³ = X kilogram / cubic centimeter

Solving for X as:

X = 7.21 g/cm³ × 1000 kilogram / cubic centimeter

X = 7.21 × 10³ kg/m³

Therefore, 7.21 × 10³ kg/m³ is the density.

Complete question is;

Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper) is called what?

Molding is what a child does with Play-Doh or origami

Answer:

Modeling

Explanation:

In chemistry, we have a branch called modeling chemistry. In modeling, we organize together a series of models instead of a collection of topics. In this approach, we will begin with a phenomena that can be readily observed and are gradually develop the simplest model of matter that helps us make sense of our observations.

Now in the question, we are Molding a shape from soft, malleable materials like clay/plaster or constructing from harder materials like metal/paper. This means that we are organizing a series of models from either soft & malleable or harder materials to produce a simple model shape.

Thus, this is simply modeling.

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{Density} [/tex]

From the question

mass = 468 g

Density = 17 g/L

Substitute the values into the above formula and solve

We have

[tex]volume = \frac{468}{17} \\ = 27.529411[/tex]

We have the final answer as

Answer: 15.83 mol

Explanation:

To convert from atoms to moles, we will need to use Avogadro's number.

Avogardo's number: 6.022×10²³ atoms/mol

[tex]9.53*10^{24} atoms*\frac{1mol}{6.022*10^2^3 atoms} =15.83 mol[/tex]

Now, we know that there are 15.83 moles.

Explanation:

Density of a substance may be defined as the amount of mass or matter it contains in a unit space or volume of that substance. It is the quantity of the matter that a body possess or contains.

Mathematically,

density = mass / volume

Different substance shave different densities. The arrangement of molecules or atom particles in the substances makes a substance less denser or more denser than the other substance.

In liquid or gas, the molecules are loosely bound to each other and there are more empty space or void spaces in the substance. Thus this make liquid and gas less dense.

On the other hand, the molecules in solid are tightly bound and they are packed, with no or very less empty space. Therefore, solids have the largest density than the gases which have the smallest density.

Answer:

Explanation:

we know that specific heat is the amount of heat required to raise the  temperature of substance by one degree mathmeticaly

Q=mcΔT

ΔT=T2-T1

ΔT=26.8-10.2=16.6

C for water is 4.184

therefore

Q=1.00*4.184*16.6

Q=69.4 j

now we have to covert joule into calorie

1 calorie =4.2 j

x calorie=69.4 j/2

so 69.4 j =34.7 calorie thats why 34.7 calorie heat is required to raise the temperature of water from 10.2 to 26.8 degree celsius

The statement which provides the theme of valuing all life found in the poem 'Birdfoot's Grampa' is the journey is more important than the destination.

The poem 'Birdfoot's Grampa' is written by the author Joseph Bruchac which narrates the story of an old man's journey to rescue the life of all toads that are seen on the road while he is driving during the night.

The poem gives us an idea that all life is important and is of value which we can understand through the immense tolerance and selflessness. The worth of our life is generally demonstrated in the poem.

Every ones life has a value whether it is small or big. This concern is shown in this poem through the character of Birdfoot's Grampa's continuous stopping of the car to rescue the toads which are seen on the road rather than just running them over.

Birdfoot's Grampa's is that much conscious and careful about the life of toads. All life is precious and the journey is more important than the destination is denoted in the poem.

Thus option A is correct - journey is more important than the destination.

Answer:

Giga, 1x10⁹.

Explanation:

Hello,

In this case, if we chew over Google's name, we can see that it suggests the word Giga which in conversion units context accounts for the Giga prefix (G) which has a value of 1x10⁹.

For instance 1 meter in gigameters is:

[tex]1m*\frac{1Gm}{1x10^9m}=1x10^{-9}Gm[/tex]

Which suggests that it is a huge unit and it makes sense considering the raft of information Google handles.

Given :

A balanced chemical equation :

[tex]Zn +Cl_2->ZnCl_2[/tex]

To Find :

How many grams of zinc are needed to produce 12 grams of zinc chloride.

Solution :

Moles of [tex]ZnCl_2[/tex] ,

[tex]n=\dfrac{Given \ wt}{Molecular\ Mass}\\\\n =\dfrac{12}{136.30}\ mol\\\\n=0.088\ mol[/tex]

Now, by balanced chemical equation we can say that 1 mol of Zn produce

1 mol of [tex]ZnCl_2[/tex] .

So, 0.088 mol of Zn is required to produced 0.088 mol of [tex]ZnCl_2[/tex] .

[tex]Mass \ required = molecular \ mass \times moles\\\\m = 65.38 \times 0.088\\\\m=5.8 \ gm[/tex]

Therefore, 5.8 grams of zinc is required.

Hence, this is the required solution.

Explanation:

The atomic number is the number of protons .In a neutral atom,the number of electrons equals the number of protons.Mass number is the sum of the protons and nuetrons of a particular isotope.If you have mass number and atomic number,subtract the atomic number from the mass number to get the number of nuetrons. Mass number- atomic number= number of nuetrons
