Answer:

Concept Formation

Explanation:

The formation of concepts is a process in which specific expressions are taken to make a generalization or a correspondence between things. The formation of concepts is very important in teaching because it is vital to acquire knowledge.

In this case, the fact that all 3-sided figures are triangles is an example of concept formation because a concept is a definition that helps us define if an object is within a certain category.

So for this example, the concept that every three-sided figure is a triangle can help us define when something can be classified or not as a triangle, thus falls into the category of concept formation.

Students conduct an experiment:

sweet-ann [11.9K]

Answer:

The balloon becomes inflated

Explanation:

The equation of the reaction between baking soda (sodium bicarbonate) and vinegar(ethanoic acid) is shown below;

NaHCO3 + HC2CH3O2 ------> NaC2H3O2 + H2O + CO2

The gas (CO2) evolved in the process leads to the inflation of the balloon dropped on the bottle in which the reaction is taking pace.

This observation provides evidence that a gas was really evolved in the reaction.

A 10.00 g sample of a soluble barium salt is treated with

icang [17]

(11.21 g BaSO4) / (233.4 g/mol BaSO4) = 0.0480 mol BaSO4 and original barium salt

<span>(10.0 g) / (0.0480 mol) = 208.3 g/mol </span>
<span>So it must have been BaCl2.

I think it letter A.

The lightest atom is the hydrogen atom. There is one proton in its nucleus.

Aneli [31]

Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1 .It has an average atomic weight of 1.0079 amu, making it the lightest element.

a.1.00784 u

b.Atomic-36

Krypton

Atomic Weight. 83.80

That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.
