Don't get me wrong the seas are, by distant, the biggest store of water on soil, over 96% of all of Earth's water exists within the seas. Not as it were do the seas give dissipated water to the water cycle, they moreover permit water to move all around the globe as sea streams. I mean, that's all i know man, give me a break.

Let's solve your problem -

The answer to the question is 4.18 10^7.

Here is my clarification/explanation to support:

To convert a standard number to scientific notation, we have to move the decimal point up until we have a 1 digit number.

When we keep moving the decimal point, we get 4.18

Now, we will count the numbers after the 8 to get the 10 area.

There are five numbers after the 8, so we get 10^5.

Now, we will add 2 more to the 5, we get 10^7

Our answer will be: 4.18 10^7

Answer:

A) Test(independent) variable is bat wings.

B) Result (dependent) Variable is the Polyjuice Potion.

C) Cauldrons and fire

Explanation:

A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.

Now, in this experiment, what is being tested is are the bat wings.. Thus;

Test(independent) variable is bat wings.

B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.

Thus, Result (dependent) Variable is the Polyjuice Potion.

C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire

Answer:

D. 1 C, 4 O and 4 H

Explanation:

a p e x, just took the quiz

According to  law of conservation of mass, the  set of atoms that must make up the equation's reactants is  1 C, 4 O and 4 H.

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Answer:

The following subsections explain the explanation according to the particular circumstance.

Explanation:

Answer:

The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).

Explanation:

According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, matter can be neither created nor destroyed. It can only be transformed.

Therefore, in a chemical reaction the atoms are conserved. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and the amount and type of atoms of the products will be the same as the reactants.

In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.

Answer:

H₂ + Cl₂ → 2HCl

Explanation:

The equation that is balanced and follows the law of conservation of mass is:

 H₂ + Cl₂ → 2HCl

Based on the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but they combine with one another".

It suggests that the number of species on both sides of the expression must be the same.

 For the given reaction:

        H₂ + Cl₂ → 2HCl

             Reactant side              Product side

H                  2                                   2

Cl                  2                                   2

Specific latent heat of fusion = ?

Solution:

The specific latent heat is usually involve in phase changes;

  H  = mL

H is the quantity of heat supplied

m is the mass

L is the specific latent heat

 Insert the parameters and solve;

Answer:

10 g H₂SO₄

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

Given:   8 g SO₃

RxN:   SO₃ + H₂O → H₂SO₄

Step 2: Identify Conversions

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of SO₃ - 32.07 + 3(16.00) = 80.07 g/mol

Molar mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 3: Stoichiometry

[tex]8 \ g \ SO_3(\frac{1 \ mol \ SO_3}{80.07 \ g \ SO_3} )(\frac{1 \ mol \ H_2SO_4}{1 \ mol \ SO_3} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )[/tex] = 9.80042 g H₂SO₄

Step 4: Check

We are given 1 sig fig. Follow sig fig rules and round.

9.80042 g H₂SO₄ ≈ 10 g H₂SO₄

Answer: Carbon

Explanation:

electronegativity decreases when you go down a column

The study of chemical bonds is called chemistry.

The correct answer is carbon.

The more negative charge present on an atom shows the electronegativity.

The attraction of the nucleus to the proton is also referred to as electronegativity.

The smaller the radius more the electronegativity.

Hence, the correct answer is Carbon as it has fewer atoms and a smaller radius.
