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.

The answer is

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]

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

Answer:

9 protons 9 electrons and 10 neutron

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

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.

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.

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.

Answer:

carbon dioxide is acidic and when it comes in contact with blue litmus paper it turns red

Explanation:

Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

Explanation:

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

Answer: 15.83 mol
