Explanation:

Producing Epoxyethane by reacting ethene in presence of a silver catalyst with a limited amount of oxygen. The temperature range of the reaction is 250 - 300°C.

The balanced reaction is as follows -

CH2 = CH2 + 1/2 O2 (Reactants) -silver catalyst--> CH2-O-CH2 (Product)

Boyle's Law

Explanation:

"Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases."

Answer:

D) contains more OH– ions than H+ ions

Explanation:

THESE ARE THE OPTIONS FOR THE QUESTION

A) causes some indicators to change color B) conducts electricity C) contains more H+ ions than OH– ions D) contains more OH– ions than H+ ions

Base can be regarded as substance which can dissociates in water then form hydroxide ions (OH–) .

Bases can be regarded as compounds which break into hydroxide ions I.e (OH-) with more other compounds if put in an aqueous solution. Hence it contains more OH– ions

Answer:

saturated

Explanation:

Answer:

The concentration of H₃O⁺ ions increase whereas the concentration of the OH⁻ decreases.

Explanation:

The water, H₂O, has its own equilibrium thus:

2H₂O(l) ⇄ OH⁻(aq) + H₃O⁺(aq)

Where the water equilibrium constant, Kw, is defined as:

Kw = 1x10⁻¹⁴ = [OH⁻] [H₃O⁺]

The addition of a base represents the increasing of [OH⁻]. that means the concentration of OH⁻ ions.

Based on LeCh principle, in an equilibrium, the addition of a product produce the decreasing in concentration of the other products trying to counteract the effect, that means the concentration of H₃O⁺ ions decreases.

Urban development has been linked to many environmental problems, including air pollution, water pollution, and loss of wildlife habitat. Urban runoff often contains nutrients, sediment and toxic contaminants, and can cause not only water pollution but also large variation in stream flow and temperatures.

Explanation:

Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.

Answer:

0.21 mole of NaCl

Explanation:

From the question,

using Avogadro's Constant,

1 mole of every compound contains 6.02×10²³ molecules of that compound.

I.e

1 mole of NaCl ⇒ 6.02×10²³ molecules of NaCl

x moles of NaCl ⇒ 1.25××10²³ molecules of NaCl

Solving for x,

x moles of NaCl = (1 mole of NaCl)×(1.25×10²³ molecules of NaCl)/(6.02×10²³ molecules of NaCl)

x moles of NaCl = (1×1.25×10²³)/6.02×10²³

x = 0.208 mole of NaCl

x ≈ 0.21 mole of NaCl

Answer:

COCl2 + H2O = 2 HCl + CO2

[tex]COCl_2 + H_2O[/tex] → 2[tex]HCl + CO_2[/tex] is the balanced equation.

The Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that the total mass on the reactant side must be equal to the total mass on the product side.

While balancing a chemical reaction first balance the atoms of other elements and then in the end balance oxygen atoms.

Hence, [tex]COCl_2 + H_2O[/tex] → 2[tex]HCl + CO_2[/tex] is the balanced equation.

Answer:

62 L

Explanation:

We are given that:

n = 2.3 mol

R = 0.082 L*atm/(mol*K), the ideal gas constant in the required units

T = 290 K

P = 0.89 atm.

therefor:

V = nRT/P

= [(2.3 mol)(0.082 L*atm)(290 K)/(mol*K)]/(0.89 atm)

= 62 L

The volume of 2.3 mol CL2 will be 62 L.

A three-dimensional element's area of coverage. The measurement of volume is done in cubic units. Decibels are a unit of measurement for the volume of sound.

Calculation of volume.

Volume can be determined by using the formula.

PV = nRT

where, P = pressure, V = volume, n = number of moles, R = gas constant and T = temperature,

It is given that, n = 2.3 mol, T = 290 K and P = 0.89 atm.

Put the value of given data in volume equation,

V = n RT/ P

V = 2.3 mol × 0.082 × 290 /0.89

V = 62 L.

Therefore, the volume will be 62 L.

Answer:

1,110.48 mL

Explanation:

37°C is 310K and 132°C is 405K

V/V' = T/T'

850/V' = 310/405

V' = (850×405)/310

=> V' = 1110.48 mL

moles PbI₂ produced = = 0.9 mole (1 sig. fig.)

Explanation:

                                                  300g         ?moles

moles KI = 300g KI/166g/mol = 1.81 mole KI

Rxn ratio for KI and PbI₂ => 2:1

∴ moles PbI₂ produced = 1/2(1.81 mole) = 0.9036144 mole (calculator answer)

= 0.9 mole (1 sig. fig.)
