Physical changes can be reversed and chemical changes can’t be reversed. A physical property is a characteristic which can be identified without changing the substance but to identify a chemical property, you do have to change the substance.

Answer:As thermal energy is transferred to the chocolate, its molecules vibrate faster and faster. Eventually they vibrate fast enough that they start to slide past each other and move around. As this happens, the chocolate changes from a solid to a liquid.

Knowing about the greenhouse effect we have that what intensifies this effect is an increase in gases in the atmosphere that absorb heat.

Greenhouse effect is a natural atmospheric phenomenon responsible for the maintenance of life on Earth. Without the presence of this phenomenon, the temperature on Earth would be very low, around -18ºC, which would make the development of living beings impossible.

Thus, the main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.

This problem is describing the combustion experiment where by the heat of combustion of 1.66 g of liquid C6H14 can be calculated via calorimetry. The calorimeter (C=11.2kJ/°C) contains 2750. grams of water with a temperature rise of 3.54 °C, it means we can calculate the total heat released by the combustion of this hydrocarbon via:

[tex]Q_{combustion}=-(Q_{calorimeter}+Q_{water})[/tex]

Because the heat of combustion is released to the water and the calorimeter. Next, we break down each heat and subsequently plug in the given values:

[tex]Q_{combustion}=-(11200\frac{J}{\°C}*3.54\°C +2750.g*4.184\frac{J}{g\°C}*3.54\°C )\\\\Q_{combustion}=-80,379J=-80.4kJ[/tex]

After that, we calculate the moles of C6H14 by considering the given mass and its molar mass (86.18 g/mol):

[tex]n=1.66g*\frac{1mol}{86.18g} =0.01926mol[/tex]

And finally, we divide the total heat of combistion by the moles to get the heat of combustion:

[tex]\Delta H_{comb}=\frac{-80.4kJ}{0.01926mol} =4,174\frac{kJ}{mol}[/tex]

Explanation:

Nonmetals have nearly full valence shells and try very hard to get that last few electrons to complete their valence shell. This allows them to achieve noble gas stability. This is why they have high electronegativities and electron affinities.

Answer:

Explanation:

step step by step explanation

Answer:

The energy that is associated with the motion or position of an object

or simply kinetic or potential Energy

Element “X” belongs to family 2A, meaning it is part of the family that includes elements such as Be and Mg. These elements will all have 2 valence electrons and can be represented by the following Lewis diagram:

Element “Y” belongs to family 5A, meaning it is part of the family of elements that includes elements such as N and P. These elements will all have 5 valence electrons and can be represented by the following Lewis diagram:

Atoms from these two families will usually react with each other by losing or gaining valence electrons to create stable ions (an ion is what we call an atom/particle that has a charge). These stable ions form by the atoms either losing or gaining electrons until they have the same number of valence electrons as the nearest Noble Gas. This means that each ion will have a full valence shell (usually consisting of 8 electrons), often referred to as a “stable octet”, and this process of creating stable ions is often called the “octet rule”.

Atoms with fewer that 4 valence electrons will normally have a weak hold on their valence electrons and will tend to lose their valence electrons when forming ions.

Atoms with 4 or more valence electrons will normally have a strong hold on their valence electrons and will tend to gain electrons when forming ions.

The charge on the ion arises from the fact that, initially, the atom is electrically neutral because it has the same number of electrons (negative charges) as protons (positive charges). By losing electrons, the atom will end up with more protons (positive charges) than electrons (negative charges) and will form an ion with an overall positive charge. By gaining electrons, the atom will end up with more negative electrons than positive protons becoming an ion with an overall negative charge.

So, an atom of element “X”, with only 2 valence electrons, must lose its 2 valence electrons (which will be gained by element “Y”) to form a stable ion with a 2+ charge (losing two electrons leaves the ion with 2 more positive charges (protons) than negative charges, so a net charge of 2+).

An atom of element “Y”, with 5 valence electrons, must gain 3 electrons (from element “X”) to form a stable ion with a 3- charge (gains 3 extra negative charges).

We can show this process using Lewis diagrams:

From this set of diagrams you can see that in order to create stable ions of both “X” and “Y” we need these atoms to react with each other in a 3:2 ratio (we need 3 atoms of X for every 2 atoms of Y). This means that the resulting chemical formula of the compound will be:

Now, we will look at a short cut that can help you figure this out without having to draw Lewis diagrams.

Compounds are electrically neutral, meaning they must contain equal numbers of positive and negative charges. For compounds consisting of oppositely charged ions, this means that the total charge of the negative ions must be equal to the total charge of the positive ions. In other words the ions must combine in a ratio that makes their charges add to zero.

If we look at the compound we just made, X3Y2, we can confirm this:

So, now you can you predict the formula of simple ionic compounds:

from the family of elements, determine the number of valence electrons each element has

determine the charge of the ions that each atom will form using the octet rule (or look on the periodic table, most will tell you the stable ionic charges that each element can form)

determine the ratio of positive ions to negative ions that results in an overall charge of zero
