Answer:

When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic ) and decomposes to form calcium oxide. Calcium oxide (also known as quicklime) is a key ingredient in the making of cement and is also used to make certain types of plaster.

Explanation:

Limestone heated

When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic ) and decomposes to form calcium oxide. ... Calcium oxide (also known as quicklime) is a key ingredient in the making of cement and is also used to make certain types of plaster.

Burning Limestone

Burning limestone, which is calcium carbonate, gives you quick lime, calcium oxide. Mixed with water this produces slaked lime, calcium hydroxide. ... This is soft when first mixed, but with time absorbs carbon dioxide from the atmosphere and hardens as it reverts back to calcium limestone.

Limestone exposed to heat and pressure.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. ... Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.

Answer:

No, light behaves as a Transverse Wave. All electromagnetic waves behave as transverse waves.

Answer: The amount of water produced is 9.3 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]

mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g

mass of products = mass of carbon dioxide + mass of water = 48.9 g +  mass of water

48.9 g +  mass of water = 58.2 g

mass of water = 9.3 g

Answer:

0.192 M NaOH

Explanation:

Answer:

Energy is transferred when atoms are rearranged

Explanation:

Breaking bonds between atoms need energy. When new bonds are formed, energy is released

The law of conservation of energy is energy isn't created or destroyed

A and B are wrong because there is creation or destruction of energy

C is wrong because energy can be transferred (think touching a hot stove with your finger.  heat is transferred from the stove to your finger OUCH!)

D is correct because the energy is still there, but in a different form

Hello! Here's the answer I was able to come up with:

Why does Na have only one dot?

Sodium, or Na, has only one valence electron.  (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)

Why do none of these diagrams show more than 8 dots?

It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.

What relationship do you notice between the dots in these two charts?

The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)

The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?

An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Don't copy this word for word! You will most likely be in trouble for plagiarism.  Instead, rewrite these ideas in your own words, or paraphrase. Good luck, and I know you can do it! ♥  

Answer:

why

Explanation:

why don't we need to answer, did you already found the answers

Answer:

Hi, valence electrons are the number of electrons present in the outermost shells of atoms of elements, they affect how sharing or transfer of electrons takes place when the atoms go into any reaction.

they also determine the oxidation state of the atom.

for example, hydrogen has one electron in its outermost shell. therefore in any reactions it tends to loose that electron or gain one more to become stable.

the reason why elements go into reactions is to become stable (to have a complete duplet or octet structure).

As you know, each shells aside from the first has maximum of 8 electrons. so for a element like chlorine which have 7 electrons in the valence shell will gain one electrons in reactions to become stable(have a complete octet structure)

valence electrons also classifies elements( metal or non-metal)

if an element have 1, 2 or 3 valence electron(s), it is likely to be a metal

if an element have 4 or 5, it can be a non-metal or a metalliod (semiconductor)

if an element have 6 or 7, it is likely to be a non-metal

if an element have 8, it is a noble/inert gas

this also explains why noble gases do not react since they already have a duplet structure, they do not need to go into reaction.

good lucks on your exams.

Answer:

The number of electrons in an atom's outermost valence shell governs its chemical properties. ... This tendency is called the octet rule, because the atoms have eight valence electrons. METALS. The most reactive metallic elements are metals from Group 1 (e.g., Na or K ) or Group 2 (e.g., Mg or Ca )

Answer:

Individual Characteristics are properties of physical evidence that can be attributed to a common source with a high degree of certainty. Examples of individual evidence include anything that contains nuclear DNA, toolmarks, and fingerprints.

Explanation:

Answer:

CH4

Explanation:

London dispersion forces are a type of force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are symmetrically distributed with respect to the nucleus. They are part of the van der Waals forces(Wikipedia).  It is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction(Chem Purdue).

If we consider HCl, C2H5OH  and NH3, we will discover that they all have polar bonds. Consequently, dipole - dipole interaction as well as hydrogen bonds exist between their molecules.

CH4 is nonpolar. Being a nonpolar molecule, the only possible intermolecular interaction forces between its molecules is the London dispersion forces.

Answer:

The reaction shifts to the left.

Explanation:

Equilibrium constant (K) = 46.3

Reaction Quotient (Q) = 525

The relationship between Q and K with their implications are given as;

K = Q (No net reaction)

K > Q (Reaction shifts to the right)

K < Q (Reaction shifts to the left)

Since in this question, Q (525) > K (46.3)

The reaction shifts to the left.

Answer:

1. Ok, so you have a 1:1 ratio of FeCl2 to FeCl3, which is shown by the fact that if you react 2 moles of FeCl2 you get 2 moles of FeCl3. So therefore, if you react 4 moles of FeCl2, you'd form 4 moles of FeCl3.

2. You have a 1:2 ratio of Cl2 to FeCl2, for every 1 mole of Cl2, you need 2 moles of FeCl2, so therefore, for 7 moles of Cl2, you need 2x7moles = 14 moles

3. 1:1 ratio. So you start with 2.28moles.

4. 1:2 ratio of Cl2 to FeCl2, so therefore to get from FeCl2 to Cl2 you need to divide by 2. Therefore, you need 3.25moles / 2 = 1.625 moles

Answer:

[tex]^A_ZX[/tex] is the notion of an atom 'X', if the mass number is A and the atomic number is Z

Explanation:

The symbol of the element is "X"

The notion comprises of symbol of element "X" in the center.

On the upper left side of the symbol mass number "A" is kept and on the lower left side of the symbol, atomic number "Z" is kept.

Thus, notion will be

[tex]^A_ZX[/tex]

Answer:

zero order reaction

Explanation:

The seem to be a reaction is zero order as the data only fits to zero order integrated rate law.

Integrated rate law:

[A] = [A]_0 – kt

Here y = [ A] and slope is -k , so when we plot concentration of A with respect to t then we get the equation in the form of line

y = mx + c

So the answer Zero order in [A]
