Salts and acids are examples of inorganic compounds called Electrolytes which dissociate in water to release ions.

<h2>Further Explanation: </h2><h3>A compound </h3>

A compound is a substances that contains two or more different atoms that are bonded together.
When the atoms are similar the substance is known as a molecule, therefore not all molecules are compounds.

<h3>Electrolytes</h3>

Electrolytes are substances that are either in molten or aqueous form that discharged by passing electric current through them. They dissociate into ions while in molten or solution form.
These compounds are made of mobile ions which are responsible for the conduction of electricity.
Examples includes, soluble salts, ionic compounds, acids, and bases etc.

A salt is a substance that is formed when an acid reacts with a base or when the hydrogen part of acid is replaced by metal ion or an ammonium ion.

<h3>Ionic compounds </h3>

Ionic compounds are compounds that contain ions. They are as a result of ionic bonding between a metal atom and a non-metal atom.
During ionic bonding formation the metallic atom looses electrons while the non-metallic atom gains electrons.
Ionic compounds contains both negatively charged ion(anion) and positively charged ion (cation).
Examples of ionic compounds, NaCl, LiF, KCl, Cs2S, KBr, PbS etc.
Most ionic compounds may act as electrolytes.

Keywords: Compound, electrolytes, salts, ionic compounds, soluble acids, bases.

Answer:

Salts and acids are examples of inorganic compounds called <u><em>electrolytes</em></u>.

Explanation:

Electrolytes are the substances which dissociates into ions when dissolved in water and due to this they are able to conduct electric current through them. These compounds in solid form does not conduct electricity due to the absence of free ions.

For example: Sodium chloride , sulfuric acid etc.

$NaCl(aq)\righarrow = Na^+(aq)+Cl^-(aq)$

$H_2SO_4(aq)\rightarrow SO_4^{2-}(aq)+2H^+(aq)$

How many moles of KOH are required to produce 4.79 g K3PO4 according to the following reaction? 3KOH + H3PO4 -----> K3PO4 + 3

8_murik_8 [283]

Answer:

0.677 moles

Explanation:

Take the atomic mass of K = 39.1, O =16.0, P = 31.0

no. of moles = mass / molar mass

no. of moles of K3PO4 used = 4.79 / (39.1x3 + 31 + 16x4)

= 0.02256 mol

From the equation, the mole ratio of KOH : K3PO4 = 3 :1,

meaning every 3 moles of KOH used, produces 1 mole of K3PO4.

So, using this ratio, let the no. of moles of KOH required to be y.

$\frac{3}{1} =\frac{y}{0.02256} \\$

y = 0.02256 x3

y = 0.0677 mol

If you don't find exactly 0.677 moles as one of the options, go for the closest one. A very slight error may occur because of taking different significant figures of atomic masses when calculating.

Why were scientists unsure about the last common ancestor between apes and humans?

nadezda [96]

Answer:

Scientists were unsure about the last common ancestor between apes and humans because fossils are so scarce, researchers do not know what the last common ancestors of living apes and humans looked like or where they originated.

A sample of gas (1.9 mol) is in a flask at 21 °C and 697 mm Hg. The flask is opened and more gas is added to the flask. The new

Artyom0805 [142]

Answer: There are now 2.07 moles of gas in the flask.

Explanation:

$PV=nRT$

P= Pressure of the gas = 697 mmHg = 0.92 atm (760 mmHg= 1 atm)

V= Volume of gas = volume of container = ?

n = number of moles = 1.9

T = Temperature of the gas = 21°C=(21+273)K= 294 K (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

$V=\frac{nRT}{P}=\frac{1.9\times 0.0821 \times 294}{0.92}=49.8L$

When more gas is added to the flask. The new pressure is 775 mm Hg and the temperature is now 26 °C, but the volume remains same.Thus again using ideal gas equation to find number of moles.

$PV=nRT$

P= Pressure of the gas = 775 mmHg = 1.02 atm (760 mmHg= 1 atm)

V= Volume of gas = volume of container = 49.8 L

n = number of moles = ?

T = Temperature of the gas = 26°C=(26+273)K= 299 K (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

$n=\frac{PV}{RT}=\frac{1.02\times 49.8}{0.0821\times 299}=2.07moles$

Thus the now the container contains 2.07 moles.
