The main precaution to take if a gas cylinder sign is present in the lab is Check sure the gas cylinder remains constrained visually, but remain a good distance from it.

A gas cylinder is indeed a pressure vessel used to store and confine gases at pressures higher than atmospheric pressure. Bottles are another name for high-pressure gas cylinders.

Based on the physical properties of the contents, the held contents may be compressed gas, vapour over liquid, working fluid, as well as dissolved in a substratum inside the cylinder.  The main precaution to take if a gas cylinder sign is present in the lab is Check sure the gas cylinder remains constrained visually, but remain a good distance from it.

Therefore, the precaution is to Check sure the gas cylinder remains constrained visually, but remain a good distance from it.

Answer:

A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.

MgS → Mg²⁺ + S²⁻

S²⁻ is known as the sulfide ion. That makes MgS Magnesium Sulfide.

magnesium sulfur  Mg & S

Magnesium sulfide is an inorganic compound with the formula MgS.

Magnesium sulfide (MgS) is an concerning ancient culture compound made by the consolidation of magnesium (Mg) cations and sulfide (S2-) anions. It is calm of individual magnesium ion (Mg2+) and individual sulfide ion (S2-).

In the formation of magnesium sulfide, magnesium drops two electrons to solve a constant eight of something configuration, making a absolutely loaded magnesium ion (Mg2+). Sulfur, in another way, gains two electrons to complete its outer energized matter structure, happening in a negatively loaded sulfide ion (S2-).

Answer:

Potassium Hydroxide Solution =

or

Potassium Hydroxide =

Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.

As it is in the question, we can map the reactants and product:

Reactants                   Product

Ammonium                 Ammonia

Sulfate                         Sulfate

________                   Potassium

________                    Water

Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.

This becomes clear when we consider the net ionic equation:

Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water

if we write this a balanced chemical equation:

(NH₄)₂SO₄   +  2KOH  →  K₂SO₄ + 2NH₃ + 2H₂O

if we write the reaction as an ionic equation

2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O

if we remove the ions that appear on both the reactant and product side (spectator ions)

The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s

2

It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.

Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s

The molar mass of hydrogen gas H₂ is 2.016 grams.

The mass of a substance divided by its concentration, expressed in grams per mole (g/mol), is known as its molar mass.

Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.

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

M = m /n

M = molar mass

m = mass of a substance (in grams)

n = number of moles of a substance

The mass of hydrogen is 1

The number of moles of hydrogen is 6.022 x 10²³

Hydrogen gas has a molar mass of 2.016 grams per mole. When two hydrogen atoms join forces to create a molecule with the formula H2, hydrogen gas is created.

Therefore, the molar mass of hydrogen gas H₂ is 2.016 grams

Block B  will need to  absorb more energy as it has higher specific heat value.

Specific heat is defined as the amount of heat required  to raise the temperature of one gram of a substance  by one degree Celsius rise. Units of specific heat  are calories or joules  per gram per degree Celsius.

Specific heat capacity  varies with temperature often  and is different for each state of matter. While the substance which undergoes phase transition then it's specific heat is technically infinite.

Specific heat of a gas is significantly higher when it is allowed to expand  as it is heated .It may also be referred to as a ratio  between the specific heat capacities of two substances at a given temperature.It is calculated by the formula ,Q=mcT

For copper, it is 100×0.385×473=18210.5 J

For aluminium ,it is 100×0.90×473=42570 J

As  the specific heat of aluminium is higher it will absorb more energy.
