Answer:

Moon rocks contain few volatile substances (e.g. water), which implies extra baking of the lunar surface relative to that of Earth. The relative abundance of oxygen isotopes on Earth and on the Moon are identical, which suggests that the Earth and Moon formed at the same distance from the Sun.

Answer:

They DON"T have the same mass !

Explanation:

Moles are the product of the molar concentration and the volume of the solution. The moles of Ferric chloride is 0.118 moles.

Moles are the smallest unit of the measurement of atoms and molecules. It is calculated by the molar concentration and the volume of the solution.

Given,

Molar concentration of ferric chloride = 0.762 M

Volume of solution = 0.155 L

Moles are calculated as:

[tex]\begin{aligned} \rm Moles &= \rm Molarity \times Volume (L) \\\\&= 0.762 \times 0.155\\\\&= 0.118\;\rm mol\end{aligned}[/tex]

Therefore, 0.118 moles of ferric chloride are present in the sample.

1436.2 calories   per mole H2O

Explanation:

one mole of water has mole weight of   2 * H   +   O =

2 * 1.008  + 15.999 = 18.015 gm

the heat of fusion for water (the heat required to turn ice to water )

Answer: Yes, we need greenhouse gases. Greenhouse gases are important because they sustain a healthy temperature on our planet. Greenhouse gases absorb heat from the sun and keep it in the atmosphere. The heat emitted by the Earth would pass outwards from its surface into space if greenhouse gases were not active. However, greenhouse gases aren’t just important. They can cause harmful consequences to our environment, too. Letting greenhouse gases into our air causes climate change and respiratory diseases from smog and air pollution.

Explanation:

Based on the heat absorbed by the calorimeter, the heat of reaction, ΔHrxn is 333.5 kJ/mol

The heat evolved or given out by the sample is the equal to the amount of heat absorbed by the calorimeter.

The heat absorbed by calorimeter is given as:

Heat = 13.3 × (56.0 - 32.0)

Heat evolved = 319.2 kJ

Moles of sample reacted = 53.8/56.23 = 0.957

ΔHrxn = 319.2 kJ/0.957 moles = 333.5 kJ/mol

Therefore, the heat of reaction, ΔHrxn is 333.5 kJ/mol.

The correct selection for 4-octyne structure is A. Hence option A is correct.

Atom is smallest entity of a body. Body is made up of atoms. it is basic building block of a body. An atom consist of electrons, protons and neutrons as sub atomic particle. whole mass of the atom is concentrated at the center of the atom which we call it as nucleus, nucleus consist of proton and neutron. Electron revolve around the nucleus at determined(fixed) orbit. Total number of protons in the atom decides the atomic number and the elements in the periodic table.

Molecule is made up of atoms, it is formed when two or more atoms bound together. The electrons in the outermost orbit are responsible for the molecule formation. Electrons are shared by the atoms in the entire molecule.

4-Octyne, also known as dipropylethyne, is a type of alkyne with a triple bond at its fourth carbon. its chemical formula is C₈H₁₄.

C₈H₁₄ are bounded like . CH₃CH₂CH₂-C ΞC-CH₂CH₂CH₃

Answer:

mass of sodium hydroxide is needed to react completely with 10.0 g of iron(III) chloride

Explanation:

Given what we know, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

We arrive at this number by taking into account the energy needed to boil 1g of water to its vaporization point. This results in the use of 2260 J of heat energy. We then take this number and multiply it by the total grams of water being heated, in this case, 5.05g, which gives us our answer of 11.4 kJ of energy required.

Therefore, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

Hi!

Let's say you have 2 different reactants, A and B, and 1 product, C.

2A + 4B -> 3C

Let's say that once we do the calculations, we find that A is the limiting reactant/reagent.

All of the A is used up in the reaction, leaving behind some excess B, and forming C.

Now that there is only B left behind, it has nothing to react with, so it cannot create any more product.

The answer is C.2,1,2

Explanation:

The reason why the answer is C.2,1,2 is because if you put a 2 Infront of the first calcium it will be balanced with the calcium in the product side and if you put one in front of the oxygen that wiil be two and it will also be balanced with the oxygen on the product side and seeing that a 2 the coefficient is already on the product side the equation is already balanced

Answer:

C. 2,1,2

Explanation:

Ca(s) + O₂ (g) →2CaO(s)

on the reactants side:

1 Ca

2 O (because the subscript 2 counts as there being 2 O molecules. if you put a 2 in front of the O₂  that would be 2x2=4)

On the product side:

2Ca

2O

you would just need to add a 2 to the Ca on the reactants side to balance the equation.
