The dangers posed by weapons of mass destruction have come to accompany center stage in international politics. There are three types of WMD: is used to characterize a variety of weapons that share two key features: their potential for large-scale destruction and the indiscriminate nature of their effects, notably against civilians, notably against civilians, there are three major types of WMD:nuclear weapons, chemical warfare agents, and biological warfare agents.

I'm fascinated with them myself,lol. Anything dangerous really.

1.They have the power to destroy the world.

2.They can wipe out your enemies.

3.If you are crazy enough to use one of these, your enemies will know not to mess with you

A 100.0 ml sample of 0.20 m hf is titrated with 0.10 m koh. determine the ph of the solution after the addition of 200.0 ml of k
xeze [42]
The balanced equation for the reaction between KOH and HF is 
KOH + HF ---> KF + H₂O
stoichiometry of KOH to HF is 1:1
the number of HF moles reacted - 0.20 mol/L x 0.1000 L = 0.020 mol
the number of KOH moles reacted - 0.10 mol/L x 0.2000 L = 0.020 mol
KOH is a strong base and HF is a strong acid therefore they completely ionise into their corresponding ions
KOH --> K⁺ + OH⁻
HF ---> H⁺ + F⁻
number of H⁺ moles reacted = number of OH⁻ moles reacted
solution is completely neutralised no excess hydroxide or hydrogen ions
therefore when solution is neutral , pH = 7
pH of solution = 7

An important Similarly between photosynthesis and cellular respiration is that both process
adelina 88 [10]

Answer:

Similarity between photosynthesis and cellular respiration is that both process :

<u>Involve production of energy </u>

<u>Exchange of gases</u>

<u>Goes through electron chain reactions</u>

<u></u>

Explanation:

<u>Photosynthesis</u> : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

<em><u>The electrons triggers the reaction of food formation</u></em>.

<em><u>Energy is released during photosynthesis.</u></em>

<em><u>Gaseous exchange between CO2 and O2 occur.</u></em>

<u>Respiration </u>:

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

<u><em>Exchange of Gases occur between organism and environment.</em></u>

<em><u>Here , mitochondrial electron transport occurs to produce ATP</u></em>.

Hence , similarity between photosynthesis and cellular respiration is that both process:

<u>Involve production of energy </u>

<u>Exchange of gases(carbon dioxide and oxygen)</u>

<u>Goes through electron chain reactions</u>

What is the temperature of a 100 liter container having 1 mole of an ideal gas at a pressure of 20 kilopascals? (Given: R = 8.31
Shalnov [3]
For this case, we use the equation for an ideal gas which is expressed as PV=nRT where P is the pressure, V is the volume, n is the number of moles and T is the temperature. We calculate as follows:

PV = nRT
T = PV / nR
T = 20 kPa (100 L) / 1 mol (8.314) 
T = 240.56 K

Answer:Because binary ionic compounds are confined mainly to group 1 and group 2 elements on the one hand and group VI and VII elements on the other, we find that they consist mainly of ions having an electronic structure which is the same as that of a noble gas. In calcium fluoride, for example, the calcium atom has lost two electrons in order to achieve the electronic structure of argon, and thus has a charge of +2:By contrast, a fluorine atom needs to acquire but one electron in order to achieve a neon structure. The resulting fluoride ion has a charge of –1:The outermost shell of each of these ions has the electron configuration ns2np6, where n is 3 for Ca2+ and 2 for F–. Such an ns2np6 noble-gas electron configuration is encountered quite often. It is called an octet because it contains eight electrons. In a crystal of calcium fluoride, the Ca2+ and F– ions are packed together in the lattice shown below. Careful study of the diagram shows that each F– ion is surrounded by four Ca2+ ions, while each Ca2+ ion has eight F– ions as nearest neighbors.

Thus there must be twice as many F– ions as Ca2+ ions in the entire crystal lattice. Only a small portion of the lattice is shown, but if it were extended indefinitely in all directions, you could verify the ratio of two F– for every Ca2+. This ratio makes sense if you consider that two F– ions (each with a –1 charge) are needed to balance the +2 charge of each Ca2+ ion, making the net charge on the crystal zero. The formula for calcium fluoride is thus CaF2.Figure 6.10.1

(a) Ca2+ ions (color) and F– ions (gray) are shown full size. “Exploded” view shows that each F– surrounded by four Ca2+ ions, while each Ca2+ ion is surrounded by eight F– ions. The ratio of Ca2+ ions to F– ions is thus 4:8 or 1:2, and the formula is CaF2. (Computer-generated). (Copyright © 1976 by W. G. Davies and J. W. Moore.)

Newcomers to chemistry often have difficulty in deciding what the formula of an ionic compound will be. A convenient method for doing this is to regard the compound as being formed from its atoms and to use Lewis diagrams. The octet rule can then be applied. Each atom must lose or gain electrons in order to achieve an octet. Furthermore, all electrons lost by one kind of atom must be gained by the other.

An exception to the octet rule occurs in the case of the three ions having the He 1s2 structure, that is, H–, Li+ and Be2+. In these cases two rather than eight electrons are needed in the outermost shell to comply with the rule.

Example 6.10.1

: Ionic Formula

Find the formula of the ionic compound formed from O and Al.

Solution

We first write down Lewis diagrams for each atom involved:

alt

We now see that each O atom needs 2 electrons to make up an octet, while each Al atom has 3 electrons to donate. In order that the same number of electrons would be donated as accepted, we need 2 Al atoms (2 × 3e– donated) and 3 O atoms (3 × 2e– accepted). The whole process is then

alt

The resultant oxide consists of aluminum ions, Al3+, and oxide ions, O2–, in the ratio of 2:3. The formula is Al2O3.Figure 6.10.1
