Answer:

Salt is an ionic compound. It dissolves easily in water (option A)

Explanation:

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

A polar molecule is one that is neutral, that is, it does not have a net charge. But it has an internal distribution of charges that form a partially positive region and a partially negative region.

Water molecules are polar, with positive partial charges on hydrogen, a partial negative charge on oxygen and a general angular structure. Its distribution of charges is due to the greater electronegativity of oxygen with respect to hydrogen, which makes the shared electrons of the O-H bonds more attracted by the O atom than by the H atom.

The salt is an ionic compound of the formula NaCl. As salt mixes in water, charged water molecules break up charged salt molecules, which combine into a weaker ionic bond. Then the salt dissociates in water in Na + and Cl-. The positively charged Na + ions are surrounded by the negative partial oxygen charges of the water molecules, while the negatively charged ions are surrounded by the hydrogen ends with a positive partial charge. Given this, it can be said that the intermolecular forces that are acting in this case are the ion-dipole forces (intermolecular force that occurs when the ions of a substance interact with the dipoles of a polar covalent molecule). This allows the salt to dissolve easily in water.

So, the correct option is A)It dissolves easily in water

1.00 L of a gas at STP is compressed to 473mL. What is the new pressure of gas?

Ratling [72]

Hello!

1.00 L of a gas at STP is compressed to 473 mL. What is the new pressure of gas?

We have the following data:

Vo (initial volume) = 1.00 L

V (final volume) = 473 mL → 0.473 L

Po (initial pressure) = 1 atm (pressure exerted by the atmosphere - in STP)

P (final pressure) = ? (in atm)

We have an isothermal transformation, that is, its temperature remains constant, if the volume of the gas in the container decreases, so its pressure increases. Applying the data to the equation Boyle-Mariotte, we have:

$P_0*V_0 = P*V$

$1*1 = P*0.473$

$1 = 0.473\:P$

$0.473\:P = 1$

$P = \dfrac{1}{0.473}$

$\boxed{\boxed{P \approx 2.11\:atm}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

The new pressure of the gas is 2.11 atm

How do you balance this Chemical Equation? C5H12O + O2 = CO2 + H2O

ICE Princess25 [194]

Answer:

The chemical equation by putting, a 2 on C₅H₁₂O, 15 on O₂, 10 on CO₂ , and 12 on H₂O in the equation;

2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O

Explanation:

Chemical equations are balanced by putting coefficients on the reactants and products to ensure the total number of atoms on the left side equal to those on the right side.
Balancing chemical equations is done to make chemical equations obey the law of conservation of mass.
According to the law of conservation of mass, the mass of the reactants should always be equal to the mass of products.
This is done by balancing chemical equations to ensure the total number of atoms on the left side is equal to that on the right side.
