Explanation:

Answer:

v = 10 m/s

Explanation:

Given: An object has a kinetic energy of 250 J and a mass of 5 kg

To find: Its velocity

Formula: [tex]KE = \frac{1}{2} mv^2[/tex]

Solution: In classical mechanics, kinetic energy (KE) is equal to half of an object's mass ([tex]\frac{1}{2}[/tex] × m) multiplied by the velocity squared. In this case, an object with a mass of 5 kg (m = 5 kg) is moving at a velocity of 10 meters per second (v = 10 m/s), the kinetic energy is equal to 250 Joules, or ([tex]\frac{1}{2}[/tex] × 5 kg) × 10 m/s².

Therefore, the velocity is v = 10 meters per second.

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

Explanation:

Given                   Pb(NO₃)₂  +    2KI     −−>    PbI₂ + 2KNO₃

                                                  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.)

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."

Cloudy with precipitation occurs due to rising and cooling causing water vapor to condense.

Weather along most fronts is usually cloudy with precipitation because the warm air present along most fronts usually rising and cooling which causes water vapor to condense. Warm fronts often bring stormy weather as the warm air rises above the cool air mass that makes clouds and storms.

These clouds form in the warm air that is located high above the cool air. As the front passes over a region, the clouds become lower which leads to rainfall so we can conclude that cloudy with precipitation occurs due to rising and cooling causing water vapor to condense.

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.

Answer:

0.018 grams

Explanation:

The number of moles (n) in such number of atoms of Aluminum must be calculated by dividing the number of atoms (nA) by Avagadro's number i.e.

n = nA ÷ 6.02 × 10^23atoms

The number of atoms of Aluminum in this question has been given as: 3.99 x 10^20 atoms.

n = 3.99 x 10^20 ÷ 6.02 × 10^23

n = 3.99/6.02 × 10^(20-23)

n = 0.663 × 10^-3

n = 0.000663moles

Next, we convert the mole value to mass in grams by using the formula;

mole = mass/molar mass

mass = mole × molar mass

Molar mass of Al = 27g/mol

mass (g) = 0.000663 × 27

mass = 0.0179

mass of Aluminum is 0.018grams

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

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:

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
