EXPLANATION:

Iron is magnetic and the other two not, which means a MAGNET could be USED to attract the iron filings out of the mixture, leaving the SALT and SAND. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.

Explanation:

All matter is made up of very SMALL particles that are not visible to naked eye. We can PROVE this by PERFORMING the FOLLOWING experiment: Take two or three crystals of POTASSIUM permanganate and add in 100ml of water. We will see that the colour of the water gets changed.

ANSWER:

The kinetic energy of the object INCREASES

Explanation:

The kinetic energy of an object is GIVEN by:

K=\frac{1}{2}mv^2K=

2

1

mv

2

where

m is the mass of the object

v is its speed

We SEE that the kinetic energy is proportional to the mass and to the square of the speed. In this problem, the speed stays the same, while the mass increases: since K is directly proportional to the mass, this means that the kinetic energy of the object increases as well.

Summary

A DECOMPOSITION reaction occurs when ONE reactant breaks down into two or more products. This can be REPRESENTED by the GENERAL equation: AB → A + B.

Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Answer:

रेडियोसक्रियता (रेडियोऐक्टिविटी / radioactivity) या रेडियोधर्मिता वह प्रकिया होती है जिसमें एक अस्थिर परमाणु अपने नाभिक (न्यूक्लियस) से आयनकारी विकिरण (ionizing RADIATION) के रूप में ऊर्जा फेंकता है। ऐसे पदार्थ जो स्वयं ही ऐसी ऊर्जा निकालते हों विकिरणशील या रेडियोधर्मी (रेडियोऐक्टिव) कहलाते हैं। यह विकिरण अल्फा कण (ALPHA particles), बीटा कण (beta particle), गामा किरण (gamma rays) और इलेक्ट्रॉनों के रूप में होती है।[1]

ANSWER:

no of moles of ATOMS PRESENT in 9 grams of aluminium is 0.33 moles. mole of a substance contains 6.022×10 atoms/molecules so 0.014324 moles will CONTAIN 0.014324×6.022×10 atoms. i.e 0.086259×10 atoms of IRON which is approximately equal to 86.259×10 atoms.

Answer:

The de-Broglie's principle states that every object that has mass and velocity , behaves both as particle and as wave.

According to this statement:

λ = =

where :

λ is the wavelength of a particle

h = Planck's constant

m= mass of the particle

v = velocity of the particle

p = momentum of the particle

This was first noticed the properties of ELECTRON.

• An electron has both mass and velocity and HENCE it should be a particle.
• Also, electrons can be diffracted in the same way as light waves GET diffracted.

Hence it was explained with de-Broglie's principle that electrons possess a dual NATURE.

ANSWER:

Carbon is the functional ELEMENT for living things because it's able to bond in many different WAYS. It can form many compounds that are essential to life. It can have sp³, sp², or sp hybridization in its compounds. This means that it can form bonds in all three dimensions and make molecules with complicated shapes
