The process in which a gaseous substance is converted into a condensed, more usable chemical substance is called fixation
Answer:
C. Gamma > beta > alpha
Explanation:
<u>Alpha rays</u> : These are positively charged and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.
These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).
<u>Beta rays</u> : They are negatively charged and have negligible mass.
On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.
<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.
Answer:
that is answer
Explanation:
symbol - elements - mass percent
S. - sulfur. - 21.945%
F. - fluorum. - 78.047%
1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
Answer:
The first molecule Avogadro constant is given as 6.022 X 10∧23/ mol
Explanation: Avogadro constant is the constituent particles of molecules, atoms and ions that make up a mole of an element or compound. Therefore, CO2 comprises one molecule, which is equivalent to 6.022 X 10∧23/ mol.
