a) longer bond. because the charges are further apart
b) shorter bond. because the charges are closer together
c) shorter bond. because the charges are both positive
d) longer bond. because the charges are closer together

Answers

Answer:

shorter bond, because charges are close apart

Explanation:

shorter the bond length more is the energy required to break the bond for example if you take three pencils of different sizes one longer One medium sized One Shot sized if you try to break them the longer pencil will break much faster than the other two because the greater the length the lesser the strength the lesser energy you need to apply to break them apart ...

How many atoms are in 123 g of calcium

Answers

Answer:

Molar mass of Ca = 40 g / mol , given 123 g Ca is 123/40= 3.075 moles,

1 mole = 6.022 * 10^23 atoms, so 3.075 moles Ca= 18.51*10^23 atoms

Explanation:

The number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.

What is calcium?

Calcium is an element present in the periodic table. It is very much needed for the strength of the bones and teeth.

"Molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound."

"The mole is a SI unit of measurement that is used to calculate the quantity of any substance".

First, calculate the moles

Moles = mass / molar mass

Molar mass of Ca = 40 g / mol

Given 123 g Ca is mass

123 / 40 = 3.075 moles,

1 mole = 6.022 x 10²³  atoms,

6.022 x 10²³ is the Avogadro number. It equals to one mole.

So 3.075 moles Ca= 18.51 x 10²³ atoms.

Thus, the number of atoms present in 123 g of calcium is 18.51 x 10²³ atoms.

PLEASE HELPPP!!! Calculate the mass (in grams) of lithium hydroxide that would be needed to produce 8.03 mol of
lithium sulfate in the reaction below.
2 LIOH + H2S04 -> Li2SO4 + 2 H20

Answers

Answer:

385g LiOH

Explanation:

Assuming the equation is balanced...

(8.03 mol Li2SO4) x (2 LiOH/ 1 Li2SO4)

= 16.1 mol LiOH ;

16.1 mol LiOH x (24g LiOH/ 1 mole LiOH) = 385g LiOH

The number of moles of LiOH needed to produce 8.03 moles is 16.06 moles. One mole of LiOH weighs, 23 g/mol. Hence, 16.06 moles weighs, 369.3 g.

What is lithium sulphate ?

Lithium sulphate is an ionic compound formed by the donation of electron from the lithium metal to the sulphate group. It is formed by the reaction of lithium hydroxide with sulphuric acid.

As per the given balanced chemical equation of the reaction, the 2 moles of lithium hydroxide LiOH gives one mole of lithium sulphate. Then, number of moles of LiOH needed to give 8.03 mol of the product is:

2 × 8.03 = 16.06 mol.

Molar mass of LiOH = 23 g/mol.

mass of 16.06 moles of LiOH = 23 ×16.06 = 369.3 g.

Therefore, the required mass LiOH is 369.3 g.

C. increasing the temperature
D. increasing the volume

Answers

A
Now gimmie brainliest

Increasing the number of molecules will decrease the pressure of a gas in a closed container. Hence, option A is correct.

What is pressure?

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid.

An increase in the number of gas particles in the container increases the

frequency of collisions with the walls and therefore the pressure of the gas.

If the temperature decreases the pressure will also decrease.

Temperature is a measure of kinetic energy. When the temperature inside the container decreases the kinetic energy will also decrease.

Hence, option A is correct.

Answer:

Okay here's the answer ↓

Step-by-step explanation:

Tropical climate is one of the five major climate groups in the Köppen climate classification. Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm to varying degrees. There are normally only two seasons in tropical climates, a wet season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense because they are receiving direct sunlight.

Why are acids called proton donors?

Answers

Acids are substances that can donate H+ ions to bases. Since a hydrogen atom is a proton and one electron, technically an H+ ion is just a proton. So an acid is a "proton donor", and a base is a "proton acceptor". The reaction between an acid and base is essentially a proton transfer.
The relationship between acids and bases is more aggressive than the donor/acceptor terminology implies. Bases don't passively "accept" protons; they rip hydrogen ions from acids. Acids don't "donate" hydrogen ions; they surrender them.

When Lithium chloride is dissolved in water, there is a steep rise in the temperature of the water. Based on the evidence, is the dissolution of lithium chloride endothermic, exothermic, or neither? Explain.​

Answers

Answer:

When some LiCl is dissolved in water, the temperature of the water increases. This means that: (A) the strength of the intermolecular forces between the water molecules is stronger than the bond energy within the LiCl lattice.

Explanation:

When Lithium chloride is dissolved in water, there is a steep rise in the temperature of the water. Based on this evidence, the dissolution of lithium chloride is exothermic.

What is an Exothermic reaction?

An exothermic reaction may be defined as a type of reaction in which energy is liberated as a product in the form of light or heat. For these types of reactions, the overall standard enthalpy change ΔH⚬ is negative. It is one of the thermodynamic processes other than endothermic.

In the reaction, lithium intensely reacts with water in order to form lithium hydroxide and highly flammable hydrogen which liberated energy and leads to the steep rise in the temperature of the product compounds. This enhancement in the temperature is accurate evidence of an exothermic reaction.  

Therefore, on the basis of the evidence that the reaction of lithium chloride in water causes a steep rise in the temperature of the water represents an exothermic reaction.

In the 1860's the Central Pacific Railroad company employed the chemist James Howden to make an explosive capable of blasting through the granite mountains of the Sierras. The railroad needed tunnels for their train to pass through. James Howden built a nitroglycerin producing lab on Donner Pass where he would make the explosive compound on command. Nitroglycerin has the chemical formula C3H5N3O9. When it is detonated, it decomposes into carbon dioxide, water, oxygen and nitrogen. What is the theoretical yield for moles of nitrogen gas produced upon detonation of 1.320 tons of nitroglycerin? There are 907185 grams in 1 ton and nitroglycerin has a molar mass of 227 g/mol. Do not include decimals in your answer.

Answers

Answer:

8 × 10³ mol N₂

Explanation:

Step 1: Write the balanced equation

2 C₃H₅N₃O₉ ⇒ 6 CO₂ + 5 H₂O + 0.5 O₂ + 3 N₂

Step 2: Convert the mass of C₃H₅N₃O₉ from tons to grams

We will use the conversion factor 1 t = 907185 g.

1.320 t × 907185 g/1 t = 1.197 × 10⁶ g

Step 3: Calculate the moles corresponding to 1.197 × 10⁶ g of C₃H₅N₃O₉

The molar mass of C₃H₅N₃O₉ is 227 g/mol.

1.197 × 10⁶ g × 1 mol/227 g = 5.27 × 10³ mol

Step 4: Calculate the moles of N₂ formed from 5.27 × 10³ moles of C₃H₅N₃O₉

The molar ratio of C₃H₅N₃O₉ to N₂ is 2:3.

5.27 × 10³ mol C₃H₅N₃O₉ × 3 mol N₂/2 mol C₃H₅N₃O₉ = 7.91 × 10³ mol N₂ ≈ 8 × 10³ mol N₂
