5 0

Answer:

<u>Distance:</u> 9 km

<u>Displacement:</u> 3 km

Explanation:

Distance takes into account the entire path that, in this case, Preston walked, while displacement, considers only the difference between the initial and final point.

In the picture, the different paths represent as a whole the distance he covered (5+3+1), whereas, the start and final point represent displacement (3-0)

Consider the following reaction where Kc = 154 at 298 K.2NO(g) + Br2(g) 2NOBr(g)A reaction mixture was found to contain 4.64×10-
IgorLugansk [536]

Answer:

The reaction is not at equilibrium and reaction must run in forward direction.

Explanation:

At the given interval, concentration of NO = \frac{4.64\times 10^{-2}}{1}M=4.64\times 10^{-2}M

Concentration of Br_{2} = \frac{4.56\times 10^{-2}}{1}M=4.56\times 10^{-2}M

Concentration of NOBr = \frac{0.102}{1}M=0.102M

Reaction quotient,Q_{c} , for this reaction = \frac{[NOBr]^{2}}{[NO]^{2}[Br_{2}]}

species inside third bracket represents concentrations at the given interval.

So, Q_{c}=\frac{(0.102)^{2}}{(4.64\times 10^{-2})^{2}\times (4.56\times 10^{-2})}=106

So, the reaction is not at equilibrium.

As Q_{c}< K_{c} therefore reaction must run in forward direction to increase Q_{c} and make it equal to K_{c}.

The Earth is always _______ as it revolves around the sun.
EastWind [94]

Answer

Rotating

Explanation:

The Earth is always being pulled towards the Sun by gravity.

The Earth is not moving fast enough to "escape" the Sun's gravity and leave the solar system, but it is going too fast to be pulled into the Sun. Therefore, it keeps going around and around( roating)- orbiting the Sun.

Baker’s yeast catalyzes the decomposition of hydrogen peroxide (dihydrogen dioxide) into oxygen and water. Directions: Add 10 mL
andreev551 [17]

Answer:

The unbalanced chemical equation: H₂O₂ → H₂O + O₂.

The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.

Explanation:

  • Hydrogen peroxide is decomposed into oxygen and water, which is a slow reaction.
  • It is can be catalyzed by using yeast.

The unbalanced chemical equation: H₂O₂ → H₂O + O₂.

The balanced chemical equation: H₂O₂ → H₂O + 1/2O₂.

1.0 mol of H₂O₂ is decomposed to 1.0 mol of H₂O and 0.5 mol of O₂.

If a yellow paint is to have 0.511% pbcro4 by mass, how many grams of chromite are needed per kilogram of paint?
Hitman42 [59]

Yellow paint has 0.511 % PbCrO4 by mass

Mass of PbCrO4 in 1 kg of paint = (0.511 / 100) * 1 kg = 0.00511 kg = 5.11 g

Moles of PbCrO4 = 5.11 g/ 323.19 g/mol

                           = 0.0158 moles

Moles of K2CrO4 also = 0.0158 moles

Moles of FeCr2O4 = 0.0158 moles K2CrO4 * (4 mole FeCr2O4 / 8 moles K2CrO4)

                            = 0.0079 moles

Mass of FeCr2O4 (chromite) = 0.0079 moles * 223.83 g/mol

                                            = 1.77 g

Paint is a colored liquid, liquefiable, or solid mastic composition that transforms into a thin solid film after being applied to a substrate. Most commonly used for protection, coloring, or adding texture. Paints come in a variety of colors and can be made in a variety of ways.

Paint consists of pigments, solvents, resins, and various additives. Pigments give the paint its color. Solvents make application easier. The resin helps dry. Additives range from fillers to antifungal agents. There are hundreds of different natural and synthetic pigments.
