What is heat transfer? Select one: O a. Thermal energy in transit due to spatial temperature difference o b. Thermal energy in t

IgorC [24]

Answer:

a. Thermal energy in transit due to spatial temperature difference .

Explanation:

Heat transfer -

Heat transfer is the exchange of the thermal energy or heat in between any physical systems .

It is the flow of energy or any form of energy from one system to another .

Heat transfer is divided into various mechanism , one of which is the thermal .

The thermal energy is the transit due to the spacial temperature difference .

Epsom salt, a common hydrate, has the formula shown below. If I measure out 125 g of epsom salt to add to my foot soak, what mas

tatiyna

Answer:

The answer to your question is 64.02 g of H₂O

Explanation:

Data

Mass of magnesium sulfate hepta hydrated = 125 g

Mass of water = ?

Process

1.- Calculate the molar mass of the salt and the molar mass of water

molar mass of MgSO₄ 7H₂O = 24 + 32 + 64 + 14 + 112 = 246 g

mass of H₂O = 2 + 16 = 18 g

2.- Use proportions to calculate the mass of water in the epsom salt

246 g MgSO₄ 7H₂O------------------------- 126 g of H₂O

125 g ------------------------- x

x = (125 x 126)/246

x = 15750/246

x = 64.02 g of H₂O

Using knowledge of intermolecular forces, explain why the yellow food coloring mixed with the water and the acetone was able to

Papessa [141]

The yellow coloring is a polar substance hence it dissolve in water. Blue dye is nonpolar hence it dissolves in less polar acetone.

In chemistry, there is a general rule that like dissolves like. A substance can only dissolve in another if there is some kind of intermolecular interaction between the substances.

The yellow food coloring is a polar substance hence it is able to dissolve in water which is a polar solvent. The blue dye is a nonpolar substance hence it dissolve in acetone which is a less polar solvent.

2. Periodic Table Layout. The periodic table is organized in horizontal rows and also in vertical

Marta_Voda [28]

Answer:

Explanation:

Columns and rows used in the periodic classification of elements shows trends in the properties of elements.

The periodic columns are called groups and they denote vertical arrangement of elements.

The horizontal rows are the periods.

Groups and Periods provides a very simple way to classify elements.
They reflect trends among different elements that are found in nature. Following these groups and periods, it is even possible to predict the nature of an undiscovered element.
Certain parts of the table have some unique elements on them with some distinctive properties that distinguish them from others.
The atomic number is the basis of this classification. By this, it is possible to delineate that elements with similar properties are located on the same group.
