They emit b) more radiation compared to cooler objects.

This is because hotter objects have more kinetic energy (in order for the particles to vibrate- and so more infrared radiation circulates in its surroundings.)

Which reason best explains why plasmas are good conductors of electricity? They have mobile charged particles. They are at extre
Korolek [52]

Answer:

They have mobile charged particles.

Explanation:

Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.

We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.

Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.

A student performs an experiment to determine the molar mass of magnesium oxide. The student repeats the experiment five times a
mestny [16]

Answer:

Percent relative error = 0.191%

Explanation:

Relative error is a measure of accuracy (How closeness is the measure to the accepted value) for a determined data. The formula is:

Percent relative error = |Experimental - Accepted| / Accepted * 100

<em>Where experimental is the average of the data:</em>

(40.220g/mol + 40.654g/mol + 40.314g/mol + 40.165g/mol + 40.554g/mol) / 5 =

40.381g/mol

Replacing using accepted value = 40.304g/mol:

|40.381g/mol - 40.304g/mol| / 40.304g/mol * 100

<h3>Percent relative error = 0.191%</h3>

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.
