Weak and strong acids?

There is no such acid which is both strong and weak. An acid is either weak or it is strong.

However, sulfuric acid as a diprotic acid is a strong acid in its first dissociation.

H2SO4 --> H+ + HSO4-

and is a weak acid in its second dissociation

HSO4- --> H+ + SO42-

==========================

It is a strong acid only for the first hydrogen ion that is produced.

(1) H2SO4 --> H+ + HSO4^-

The remaining bisulfate ion, HSO4^-, is a weak acid and only partially dissociates.

(2) HSO4^- <==> H+ + SO4^2-

A misconception is that since sulfuric acid is a strong acid, that it dissociates like this:

(3) H2SO4 --> 2H+ + SO4^2-

That simply isn't the case except for extremely dilute solutions. As the concentration of the acid decreases, the acid behaves more and more like a strong diporotic acid. At "infinite dilution" it is accurate to write the dissociation as equation (3).

What are the Disadvantages of Microsoft Publisher?

You will want to make sure that you train someone in Linux really well. Alternately, you could hire someone who has experience with Linux. A good Linux administrator needs to be on hand as you start to migrate your systems over. This is a disadvantage financially, at least in the beginning. You may find over time, however, that you only need a temporary administrator to handle the routine tasks.

Some of the latest and greatest hardware that is being produced is not compatible with Linux. At least, not yet. The people that contribute program code and drivers to the Linux kernel are great at including support fairly quickly. Until that time, not everything you buy for hardware in your system may work. I've had to rely on third-party drivers and other means to make hardware like a new Ethernet card work. Eventually, the support will be built in. One thing you can do is before your purchase, ask if the hardware vendor has support for Linux. Some manufacturers do write their own Linux drivers and distribute them with your purchase, making it very easy to integrate with your existing system.

also....

There's no standard edition of Linux. Whereas Microsoft offers several different editions of each version of Windows, there are countless variations of Linux. For a new user it can be confusing to work out which is best for you.

also...

Because Linux is neither as popular as Windows, nor a commercial product, support works in a different way. You may have to look harder to find the answer to a problem and, while Linux supporters are more likely to offer help, it may not always match your own level of technical understanding.

also..

While Linux can be suitable for an individual user, its small market share means it's much harder to introduce in a corporate setting. With most office workers already familiar with Windows and Microsoft programs, there'll likely be a notable time cost in converting staff to using a Linux system.

and much more which i cant be asked to type up..

Hope it helped

Who is the longest person to stay on the computer?

It's difficult to determine the longest amount of time someone has stayed on a computer as this can vary greatly among individuals.

How many hours do Americans spend on the computer each day?

Those ages 8 to 18 spend more than seven and a half hours a day with such devices, compared with less than six and a half hours five years ago, when the study was last conducted. And that does not count the hour and a half that youths spend texting, or the half-hour they talk on their cellphones... from NY times

I would estimate the average for adults is about 5 hours. Some one hour to 12 hours... I have not found documented studies on this yet.

Three cells with generation times of 30 minutes are inoculated into a culture medium How many cells are there after 5 hours?

There would be 32 cells after 5 hours. This is calculated by realizing that 5 hours is equivalent to 10 generations (5 hours / 30 minutes per generation), and each cell doubles in number in each generation (2^10 = 32).

Do virtual servers exist in real life?

Virtual servers behave like real server machines, just that it runs in software.

Convert 78 square meters to cubic meters?

This is not a valid conversion. Cubic units is a measure of volume while square units is a measure of area. Generally, volume is determined by multiplying length x width x depth. Area is normally determined by multiplying length x width.

How can hard water be softened?

By the addition of washing soda (sodium carbonate)Calcium and magnesium ions present in hard water react with sodium carbonate to produce insoluble carbonates. The water now contains soluble and harmless sodium salts.

Calgon processCalgon is a trade name of a complex salt, sodium hexametaphosphate

(NaPO3)6. It is used for softening hard water. Calgon ionizes to give a complex anion:

The addition of Calgon to hard water causes the calcium and magnesium ions of hard water to displace sodium ions from the anion of Calgon.

This results in the removal of calcium and magnesium ions from hard water in the form of a complex with Calgon. The water is softened and sodium ions are released into water.

By the ion-exchange process (Permutit process)Permutit or sodium aluminum silicate is a complex chemical compound, which occurs as a natural mineral called Zeolite. Permutit or zeolites are insoluble in water and have the property of exchanging ions present in them with the ions present in the solution.

Permutit or zeolites are packed in a suitable container and a slow stream of hard water is passed through this material. As a result, calcium and magnesium ions present in hard water are exchanged with sodium ions in the permutit (Na+Al-Silicate). The outgoing water contains sodium salts, which do not cause hardness.
