Answer: Mass is 2.50 g

Explanation: reaction 2 Cu + S ⇒ Cu2S

Amount of Cu = m/M = 2.00 g /63.55 g/mol= 0.03147 mol

Amount of Cu2S = 0.5 n(Cu) = 0.01574 mol

M(Cu2S)= 159.17 g/mol, m = n·M

Answer:

Crystal structure

Explanation:

This is because minerals are organic or inorganic substances found naturally on the Earth and there are ordered substances at with atomic or molecular level. They are solid at normal Temperature. They have defined chemical composition and also have crystal structures.

Answer:

Solids, liquids, gases - all matter - are made up of atoms (or other things, like molecules, that are made from atoms)! ELEMENTS are the kinds of atoms that we can have. Carbon is an element, hydrogen is an element, and so is oxygen. ... Atoms can join together - they form bonds together - to make MOLECULES.

Answer:

C. 33.6L

Explanation:

Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.

To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:

Moles H2:

3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced

Volume:

PV = nRT

V = nRT / P

Where P is pressure = 1atm at STP

V is volume = Our incognite

n are moles of the gas = 1.50 moles

R is gas constant = 0.082atmL/molK

T is absolute temperature = 273.15K

V = nRT / P

V = 1.50mol*0.082atmL/molK*273.15K / 1atm

V = 33.6L

CH4(g) + 2O2(g) CO2(g) + 2H2O(g) + 802 kJ/mol

Explanation:

Hope this helps!!!

Have a great day!!!

The reaction [tex]CH_{4} (g)+2O_{2}[/tex] → [tex]CO_{2}(g) +2H2_{O} (g)+802kJ/mol[/tex]

shows combustion reaction of methane in which energy 802 KJ/mol energy produces.

A combustion reaction occurs when a substance combines with oxygen gas and produces energy in the form of light and heat. One of the reactants in combustion reactions must be oxygen. Water vapor is produced when hydrogen gas is burned.

It can be seen that this reaction give carbon di-oxide and water hence, combustion reaction will show this reaction.

[tex]CH_{4} (g)+2O_{2}[/tex] → [tex]CO_{2}(g) +2H2_{O} (g)+802kJ/mol[/tex]

the correct answer will be option (c).

Aqua regia is a corrosive, fuming yellow solution that is a 1:3 mixture of concentrated nitric and hydrochloric acids.

Aqua regia is a mixture of hydrochloric acid (HCl) and nitric acid (HNO3) at a ratio of either 3:1 or 4:1. It is a reddish-orange or yellowish-orange fuming liquid. The term is a Latin phrase, meaning "king's water". The name reflects the ability of aqua regia to dissolve the noble metals gold, platinum, and palladium.

Kb = 2.23 x 10⁻⁵

Explanation:

Benz-CO-NH₂ + H₂O => Benz-CO-NH₃⁺OH⁻ ⇄ Benz-CO-NH₃⁺ + OH⁻

given pOH = 2.91 => [OH⁻] = 10E-2.91 = 1.23 x 10⁻³M

                         Benz-CO-NH₃⁺OH⁻ ⇄ Benz-CO-NH₃⁺   +       OH⁻

At Equilibrium           0.68M                    1.23 x 10⁻³M          1.23 x 10⁻³M

Kb = [Benz-CO-NH₃⁺][OH⁻]/[ Benz-CO-NH₃⁺OH⁻]

= (1.23 x 10⁻³)² M²/ 0.068M = 2.23 x 10⁻⁵

0.714g of Helium is contained in the balloon

STP stands for standard temperature and pressure. STP refers to a specific pressure and temperature used to report on the properties of matter.

According to IUPAC( International Union of Pure and Applied Chemistry), it is defined as -

It is generally needed to test and compare physical and chemical processes where temperature and pressure plays an important role as they keep on varying from one place to another.

One mole of a gas under STP conditions occupies a volume of 22.4L.

Given,

Volume = 4L

1 mole of a gas occupies 22.4L of volume at STP.

Thus, 1L of a gas occupies = 1 / 22.4 moles

so, 4 L will occupy = 4 / 22.4 moles

                               = 0.178 moles

Moles = mass / atomic mass

Mass =  moles × atomic mass of He

             = 0.178 × 4

              = 0.714g

Therefore, 0.714g of Helium is contained in the balloon.

Explanation:

the answer is D they both increase

When ethylene glycol (an antifreeze) is added to water, the boiling point of the water increases, and the freezing point decreases.

Antifreezers are the substance which on mixes with any other compound will decreases the freezing point of that compound.

When we add ethylene glycol which is an antifreeze substance in the water then depression in freezing point takes place but at the same time elevation in boiling point also happen, because they had a great attraction force within themselves.

Hence increasing in boiling point and decreasing in freezing point takes place.
