Why is it dangerous to react sodium and potassium with dulute sulphuric acid?​

Chemistry

spin [16.1K]3 years ago
5 0

Answer:

Because sodium and potassium are very reactive metals so they react explosively with HCL and H2SO4 evolving a large amount of heat.

Answer:

Potassium, sodium, lithium and calcium all react violently

with dilute sulfuric acid and dilute hydrochloric acid.

It is dangerous to put thesemetals into an acid.

The reaction is similar to the reaction with water,

forming the metal salt (either sulfate or chloride) plus H2(g).

What is the total number of hydrogen atoms contained in one molecule of (NH4)2C204?
Ber [7]

Answer:

=8 atoms

Explanation:

In (NH4)2C2O4 there are four moles of Hydrogen in the compound (NH4), but there two molecules of (NH4) in this compound.  That's what the 2 in (NH4)2 means, so multiply 4 x 2 = 8.

Hope this helps (:

Wht are the trends for electronegativity and ionzation energy similar​
FinnZ [79.3K]

Answer:

Along period electronegativity and ionization energy increases.

Along group electronegativity and ionization energy decreases.

Explanation:

Along period:

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. Thus the attraction of the atoms for valance electrons increases. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required, and electronegativity also increases.

Along group:

As we move from top to bottom in periodic table the atomic sizes increases.The electrons are added in next energy level in every next element. Thus the valance electrons farther away from the nucleus and hold of nucleus becomes weaker,  because of weak nuclear attraction atomic radii increases and electronegativity and ionization energy decreases.

igor_vitrenko [27]

Answer:

Option D: More than 30 seconds

Explanation:

The enzyme CATALASE is found in almost all living organisms. CATALASE helps in the decomposition of one substance into another substance. CATALASE will breaks down hydrogen peroxide into water and oxygen.

When the potatoes were boiled it will surely produce no bubbles because the heat would have degrade the enzyme - catalase While the potatoes at room temperature potato produced the most bubbles because catalase works best at a room temperature.

If the potato solution was boiled for 10 minutes and cooled for 10 minutes before being tested, the average time for the disks to float to the surface of the hydrogen peroxide solution would be MORE THAN 30 SECONDS

lukranit [14]

Answer:

It reads as follows: 0.5 moles of solute per liter of solution.

Explanation:

Molarity is the most frequent way of expressing the concentration of solutions in chemistry, and it indicates the number of moles of solute dissolved per liter of solution; is represented by the letter M.
