Answer : The correct option is, (B) The SI system

Explanation :

As there are two systems for measuring the units which are English and Metric system.

Metric system : The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.

SI system : SI system means the international system of units and it is the modern form of metric system. It is defined as a scientific method to express the magnitude of the several basics units.

There are seven basic units in the system from which the other units are derived.

The seven base unit are, meter for length, kilogram for mass, second for time, ampere for current, kelvin for temperature, mole for amount of substance and candela for intensity.

English system : The English system measured the things in feet, inches, pounds, mile, etc.

US customary system : It is the system of measurement that is used in the united state. It is also known as English system.

Hence, the another name for metric system is, the SI system.

PLEASE HELP!!!!!!!!Which of the following chemical reactions is best clasified as an acid-base reaction?

ANTONII [103]

Answer:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

Explanation:

The given reactions are:

a . 2HgO → 2Hg + O₂,

It is a decomposition reaction, that HgO is decomposed to give Hg and O.

b . Na₂SO₄ + BaCl₂ → BaSO₄ + 2NaCl,

It is a double replacement reaction where two salts replaces their cations and anions with each others producing 2 new salts.

c . Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag,

It is a single replacement reaction, that Zn replaces Ag from its salt.

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

It is acid-base reaction "neutralization reaction" where H₂SO₄ (acid) reacts with KOH (base) producing K₂SO₄ (salt) and water.

So, the right choice is:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

Answer:

1. Density of the rectangular prism is 20 g/cm3

2. A material's ability to dissolve : Soubility

3. Intensive property : A physical property that is independent of sample size.

Explanation:

Volume of Prism is calculated by :

$volume = L\times W\times H$

Length = 3 cm

Width = 2 cm

Height = 1 cm

$volume = 3\times 2\times 1$

V = 6 cm3

mass = 120 g

$Density = \frac{mass}{Volume}$

$Density = \frac{120}{6}$

Density = 20 g/cm3

Solubility :

It is the chemical property of the substance.

It shows the ability of the solute to dissolve in the solvent at a given temperature.

Intensive Properties:

These are bulk properties(Do not depend upon the amount of matter present)
They are independent of sample size.
Example : boiling point,melting point,temperature,refractive index

Which physical quantity is not used when determining the stoichiometry in this experiment?

Reptile [31]

The physical quantity that is not used when determining the stoichiometry in this experiment is temperature.

Stoichiometry offers a way in which we can calculate the amount of reactants and products using mass - mole relationship. The mass of reactants, number of moles of reactant, mass of product and mass of precipitate can all be used to determine the stoichiometry.

However, the temperature of a reaction is not used to determine the stoichiometry of the reaction.
