Why do galvanized iron article do not get corroded even if the zinc layer goes off?

Posted by Manas Thakare 5 years, 11 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 10 months ago

The galvanized iron object remains protected even if a break occurs in the zinc layer because zinc is more easily oxidized than iron. Hence, the zinc continues to corrode but iron object does not corrode or rust.

When acid react with base to form salt and water

0Thank You

Yogita Ingle 5 years, 11 months ago

Neutralization is a chemical reaction in which an acid reacts with a base to form salt and water. In this process, a hydrogen ion of the acid combines with a hydroxide ion of the base to form a water molecule. The anion of the acid combines with the cation of the base to form a salt.

For example when hydrochloric acid reacts with sodium hydroxide the chlorine of hydrochloric acid combines with sodium of sodium hydroxide to form sodium chloride. The hydrogen of hydrochloric acid combines with the hydroxyl part of the sodium hydroxide and forms water.
HCl + NaOH → NaCl + H₂O

Aseem Mahajan 5 years, 11 months ago

Aadya Singh ? 5 years, 11 months ago

Because diluting a acid is a highly exothermic process in which large amount of heat is produce...when we add acid to water, then all the heat produced is absorbed by the water...but when we add water to acid then the water may acid may splashes on our face and clothes and cause severe damage...hence, it is recommended that acid should be added to water...

What is anti matter and dark matter

Posted by Himanshu Purohit 5 years, 11 months ago

CBSE > Class 10 > Science

2 answers

Yogita Ingle 5 years, 11 months ago

Antimatter is just regular matter with a few properties flipped, such as the electric charge. For example, the antimatter version of an electron is a positron. Antimatter is very rare in our universe compared to regular matter, but there are small amounts of antimatter all over the place in the natural world, including inside your body. Antimatter is created by many types of radioactive decay, such as by the decay of potassium-40.

Dark matter is matter that does not interact electromagnetically, and therefore cannot be seen using light. At the same time, dark matter does interact gravitationally and can therefore be "seen" through its gravitational effect on other matter. It is common throughout the universe and helps shape galaxies. In fact, recent estimates put dark matter as five times more common than regular matter in our universe. But because dark matter does not interact electromagnetically, we can't touch it, see it, or manipulate it using conventional means. You could, in principle, manipulate dark matter using gravitational forces. The problem is that the gravitational force is so weak that you need planet-sized masses in order to gravitationally manipulate human-sized objects. There remains much unknown about dark matter since it is so hard to detect and manipulate. Dark matter is not predicted or explained by standard particle physics theories but is a crucial part of the Big Bang model.
