A salt is best described as a compound that is formed from the reaction betweenan acid and a base.
a strong acid and a weak acid.
a strong base and a weak base.
an acid and water.

Answers

Answer 1

Answer:

The right answer is A (strong acid with strong base).

The reaction of an acid with a base to produce salt and water alone is called a neutralization reaction.

A salt is a compound formed following a replacement of the hydrogen ions (H +) of an acid with a basic radical during a reaction.

A normal salt is formed by the complete replacement of the H + of an acid (example Na2CO3).

while an acidic salt is formed by the incomplete replacement of the H + of an acid (eg NaHCO3).

Final answer:

The chemical reaction between copper(II) sulfate and ammonium sulfide producing copper(II) sulfide and ammonium sulfate is balanced when written as CuSO4 + (NH4)2S → CuS + (NH4)2SO4. This adheres to the principle of conservation of mass, ensuring an equal number of each type of atom on both sides.

Explanation:

The balancing chemical equation in question, copper(II)sulfate + ammonium sulfide = copper(II) sulfide + ammonium sulfate, starts off with the substances copper(II) sulfate and ammonium sulfide on the left side of the equation. In the process being described, these compounds engage in a chemical reaction, resulting in the formation of new substances, copper(II) sulfide and ammonium sulfate, which are represented on the right side of the equation. The balanced form of this equation is: CuSO4 + (NH4)2S → CuS + (NH4)2SO4.

An important concept in Chemistry is the principle of conservation of mass, which states that the total mass of substances does not change during a chemical reaction. Therefore, for a chemical equation to be balanced, there must be an equal number of each type of atom on both the left and right sides of the equation.

Applying this to the equation, we have 1 atom of copper (Cu), 1 atom of sulfur (S), 4 atoms of oxygen (O), 2 atoms of nitrogen (N), and 8 atoms of hydrogen (H) on both sides of the equation, which confirms that it is properly balanced.

Enter the symbol of a sodium ion, Na+, followed by the formula of a sulfate ion, SO42−. Separate the ions with a comma only—spaces are not allowed. Express your answers as ions separated by a comma.

Answers

Sodium and sulfate are known to form the anion and cation by the gain and loss of electrons. Sodium forms a cation, Na⁺ and sulfate form anions, SO₄²⁻.

What are anions and cations?

Anions and cations are ions formed as charged entities formed by losing and gaining electrons from the valence shell. They completely transfer their electrons to form the ionic bond.

The cation is formed by the loss of electrons from a neutral atom when there are more electrons in the valence shell. Sodium form cations as,

Na (neutral atom) - e⁺ → Na⁺ (cation)

The anions are formed by gaining electrons from a neutral atom when there is less number of electrons in the valence shell. Sulfate form anions as,

SO₄ (neutral atom) + e⁻ → SO₄²⁻ (anion)

Therefore, ions are Na⁺, SO₄²⁻.

The respective symbols of sodium and sulphate ions are $\boxed{{\text{N}}{{\text{a}}^ + },{\text{ SO}}_4^(2 - )}$ .

Further explanation:

The species that are produced after loss or gain of electrons are known as ions. Since ions are charged entities, these can be either positively charged or negatively charged. The positively charged ions are formed by the loss of electrons from the neutral atom and are known as cations. The negatively charged ions are called anions and are formed by the gain of electrons to the neutral atom.

The formation of anion occurs as follows:

${\text{A}}\left( {{\text{Neutral atom}}} \right) + {e^ - } \to {{\text{A}}^ - }\left( {{\text{Anion}}} \right)$

The formation of cation occurs as follows:

${\text{C}}\left( {{\text{Neutral atom}}} \right) - {e^ - } \to {{\text{C}}^ + }\left( {{\text{Cation}}} \right)$

The atomic number of Na is 11 so it has a configuration of $1{s^2}2{s^2}2{p^6}3{s^1}$ . It easily loses its 3s electron to form ${\text{N}}{{\text{a}}^ + }$ whose configuration becomes $1{s^2}2{s^2}2{p^6}$ . These ions are beneficial for heart activity, regulation of blood and body fluids and in transmission of nerve impulses. The formation of ${\text{N}}{{\text{a}}^ + }$ occurs as follows:

${\text{Na}}\left( {1{s^2}2{s^2}2{p^6}3{s^1}} \right) - {e^ - } \to {\text{N}}{{\text{a}}^ + }\left( {1{s^2}2{s^2}2{p^6}} \right)$

${\text{SO}}_4^(2 - )$ is a polyatomic ion that involves a central sulphur atom surrounded by four oxygen atoms and has a charge of -2 on it. These ions are used as cleansing agents in soaps and shampoos.

A vineyard has 145 acres of Chardonnay grapes. A particular soil supplement requires 5.50 g for every square meter of vineyard. How many kilograms of the soil supplement are required for the entire vineyard? (Recall that 1 km2 = 247 acres.) Express your answer in kilograms to three significant figures.

Answers

1.36.10 ^ 6 kg of supplements are required for the entire vineyard

Further explanation

7 main quantities have been determined based on international standards, namely:

1. Length, meters (m)

2. Time, second (s)

3. Mass, kilograms (kg)

4. Temperature, kelvin (K)

5. Light intensity, candela (cd)

6. Electric current, ampere (A)

7. Amount of substance, mol (m)

Derivative magnitude is a quantity derived from one or more principal quantities. So in addition to 7 principal quantities, other quantities are derived quantities

An area with the formula length x width is a unit derived from the length of the principal. The international standard unit is square meters (m²).

other area units: Km², hm², dam², m², dm², cm², and mm²

Hectare is an SI unit

1 Hectare is equal to 100 a (Are) or 10000 m² (ten thousand square meters) or 100 x 100 m 1 Hectares = 2.47 acres

In the question , there is a 145 acres vineyard, with the supplement is given 5.5 gram / m² vineyard.

So for 1 km², a supplement =

1 km² = 10⁶ m²

5.5 gram / m² = 5.5.10⁶ grams / km²

whereas 1 km² = 247 acres and vineyard = 145 acres so

$5.5.10^6*(145)/(247)$

= 3.2287.10⁶ grams

= 3.23.10³ kg (3 significant numbers: 3,2 and 3)

The soil supplement required for the entire vineyard is $\boxed{3.23 * {{10}^3}{\text{ kg}}}$ .

Further Explanation:

There are two types of units. One is basic or fundamental while the other ones are derived units. Basic units cannot be further reduced and other quantities are expressed in these units. Derived units are those that can need basic units to express themselves. Area, density, volume and velocity are some examples of derived units.

Seven basic units are present in the SI system. These are as follows:

1. Meter (m)

2. Kilogram (kg)

3. Second (s)

4. Kelvin (K)

5. Ampere (A)

6. Mole (mol)

7. Candela (Cd)

Firstly, the area of vineyard has to be converted into ${\text{K}}{{\text{m}}^2}$ . The conversion factor for this is,

$1{\text{ acre}} = \left( {\frac{1}{{247}}} \right){\text{ K}}{{\text{m}}^2}$

Therefore the area of vineyard can be calculated as follows:

$\begin{aligned}{\text{Area of vineyard}} &= \left( {145{\text{ acres}}} \right)\left( {\frac{{1/247{\text{ K}}{{\text{m}}^2}}}{{1{\text{ acre}}}}} \right)\n&= 0.587045{\text{ K}}{{\text{m}}^2}\n\end{aligned}$

The area is again converted into ${{\text{m}}^{\text{2}}}$ . The conversion factor for this is,

$1{\text{ K}}{{\text{m}}^2} = {10^6}{\text{ }}{{\text{m}}^2}$

So the area of vineyard can be calculated as follows:

$\begin{aligned}{\text{Area of vineyard}}&= \left( {0.587045{\text{ K}}{{\text{m}}^2}}\right)\left( {\frac{{{{10}^6}{\text{ }}{{\text{m}}^2}}}{{1{\text{ K}}{{\text{m}}^2}}}}\right)\n&= 587045{\text{ }}{{\text{m}}^2}\n\end{aligned}$

The amount of supplement required for the entire vineyard can be calculated as follows:

$\begin{aligned}{\text{Amount of supplement required}}&= \left( {587045{\text{ }}{{\text{m}}^2}} \right)\left( {\frac{{5.50{\text{ g}}}}{{1{\text{ }}{{\text{m}}^2}}}} \right)\n&=3.2287475 * {10^6}{\text{ g}}\n\end{aligned}$

The amount of supplement is to be converted into kg. The conversion factor for this is,

$1{\text{ g}} = {\text{1}}{{\text{0}}^( - 3)}{\text{ kg}}$

Therefore the amount of supplement can be calculated as follows:

$\begin{aligned}{\text{Amount of supplement}}&= \left({3.2287475 * {{10}^6}{\text{ g}}} \right)\left( {\frac{{{{10}^( - 3)}{\text{ kg}}}}{{1{\text{ g}}}}} \right)\n&= 3.2287475 * {10^3}{\text{ kg}}\n&\approx 3.23 * {10^3}{\text{ kg}}\n\end{aligned}$
