Answer:

Name the non-metal furthest to the left on the periodic table by its elemental name.

Name the other non-metal by its elemental name and an -ide ending.

Use the prefixes mono-, di-, tri-.... to indicate the number of that element in the molecule.

im prolly wrong

The example which accurately describes a solution is; Polar sugar molecules dissolve in water, which is polar.

According to the question:

The formation of a solution requires that the solvent and solute be of the same polarity.

I did the Exam and got it right!

This problem is providing a comparison on the atoms forming formaldehyde, CH₂O, in terms of the groups they are in, C in group 4A, O in group 6A and H in group 1A, and it is asking for a description about the bonds once they are bonded in a formal Lewis dot structure.

In such a way, the attached file shows the Lewis dot structure, in which we can find two bonds between the two hydrogen atoms and the carbon one, and also, a double bond between carbon and oxygen.

The aforementioned is explained by bearing to mind the concept of octet, which states that elements in groups 4A, 5A, 6A and 7A are able to complete 8 valence electrons after bonding.

Thus, since carbon is in group 4A we infer it needs 4 more electrons to complete the octet, and that is achieved due to the 4 bonds it is having with the two hydrogen atoms and double bond with the oxygen atom.

In addition, since oxygen is in group 6A, we infer it needs two more electrons to complete its octet, which is attained via the double bond it has with the carbon atom. For hydrogen, however, it can complete one bond at maximum, because it is in group 1A, which means it can complete two valence electrons after bonding.

Explanation:

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Answer:

Hydrogen atoms are fused into deuterium, then helium-3, then helium-4, each step giving off large amounts of energy.

Answer:

The correct answer choice is A. A chemical change has occurred because new compounds have been produced.

Explanation:

A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.Example: Melting of ice A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.Example: photosynthesis

Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.

Thus the true statement is a chemical change has occurred because new compounds have been produced.

Answer:

Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between elements that are far apart on the periodic table.

Answer:

There are two -NH2 groups around the C=O. bond in the urea molecule structure. There are one lone pairs on each nitrogen atoms and two lone pairs on oxygen atom.

The molecule urea that the molecular geometry of the nitrogen atoms is tetrahedral.

The term molecular geometry has to do with the arrangement of atoms around the central atom. On this case, we are looking at the arrangement of atoms around nitrogen.

We can see from the molecule urea that the molecular geometry of the nitrogen atoms is tetrahedral.

Answer:

So we're trying to find the number of carbon moles in the compound. We know that we have 200g of the compound and that 40% of it is Carbon. and 40% of 200 is 80g (change 40% into a decimal and multiply it by 200 and you get 80g)

So 80g of the compound is carbon. In order to find the moles of Carbon, I have to divide the mass by the molar mass of the element.

We know from our periodic table that the molar mass for carbon is 12g/mol

[tex]\frac{80}{12} = 6.67\ mol[/tex]

Therefore we have 6.67 moles of carbon in the compound

Answer:

6.67 moles of carbon in compound
