A student measures the acidity of a solution and
concludes that it has a pH of 2.70. However, the
seller claims that its pH is 3.20. What is the
percent error in the student's measurement?

Answers

Answer:

15.63%

Explanation:

The formula of error percentage is:

([experimental value-real value]/real value)100%

You divide the subtraction of the absolute value of experimental value (the one you got during a experiment) and the one that's "proven" to be right by again, the proven value. You got a decimal and all you have to do is multiply it by 100%

If 48.3g of iron is completely rusted in oxygen to produce 62.5g of iron (III) oxide, how many grams of oxygen are involved in the reaction?

Answers

The amount of oxygen involved in the reaction would be 20.7 g

The equation of rusting of iron is as follows:

[tex]4Fe + 3O_2 ---> 2Fe_2O_3[/tex]

The mole ratio of Fe to O2 is 4:3.

Mole of 48.3 g Fe = mass/molar mass

                               = 48.3/56

                                = 0.8625 moles

Equivalent mole of O2 = 0.8625 x 3/4

                                       = 0.6469 moles

Mass of 0.6469 moles O2 = mole x molar mass

                                             = 0.6469 x 32

                                              = 20.7 g

D. A warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

A warm front is a phenomenon in which a warm air mass replaces a cold air mass, creating fog and rain on one occasion. While the cold front is the replacement of a warm air mass by a cold air mass changing the pressure and creating a thunderstorm in the middle of summer. The warm front happens in zones close to the equator and the cold fronts happen in almost every place.

Answer:

Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.

The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.

HOW TO CALCULATE NUMBER OF MOLES:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molar mass.

no. of moles = mass ÷ molar mass

According to this question, a sample of water has a mass of 18.0g. The number of moles is calculated as follows:

no. of moles of H2O = 18.0g ÷ 18g/mol

Is this an example of an endothermic or exothermic reaction? Why?

Answers

Answer:

Explanation:

Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.

Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.

This reaction, just by definition is endothermic.

Answers

CH4 has more ideal gas behavior than CCl4 due to its higher intermolecular interaction.

We must note that ideal gases have minimal interaction with each other. Hence, in deciding which gas has ideal gas behavior, we have to consider the gas that has the least degree of intermolecular interaction.

However, the both gases contain nonpolar molecules but CCl4 has a greater molecular mass and has more intermolecular interaction than CH4 hence CH4 has greater ideal gas behavior than CCl4.

Suppose you have samples of three unknown solids. Explain how you could use their properties to determine whether or not they are ionic solids.

Answers

Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.

What are Ionic solids?An ionic solid is a solid formed by ionic bonds. They are the solid version of ionic compounds, which are held together by strong electrostatic energies.

What properties do they possess?Among their many properties, ionic solids possess high melting and boiling points.These solids are also known to conduct electricity well when dissolved into water, however, this can be tested after melting them as they will not conduct electricity in a solid state.A final property that we can use to identify them is that they provide a good means of insulation.Each of these properties can be tested and will allow us to determine the ionic solids amongst the samples.

Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.
