% by means of mass - ANS-%(m/m) = mass of solute/ mass of solution x 100
% through extent - ANS-%(v/v)= extent of solute/quantity of answer x 100
% mass-quantity - ANS-%(m/v)= mass of solute/ volume of answer x100
1.00 atm equals ...... - ANS-1 torr
14.7 psi - ANS-1.00 atm equals ....
5 types of reactions - ANS-combustion
composition
decomposition
unmarried replacement
double substitute
760 mmHg equals .... - ANS-1.00 atm
accuracy - ANS-refers to the correctness of size information
acid base indicator - ANS-a compound that reveals one of a kind colours relying at the pH of its
answer
acid ionization consistent - ANS-Ka - an equilibrium constant for the ionization of an acid in
aqueous option to H+ and its conjugate base
Ka = H+ A-/ HA
Acid energy increases because the value of Ka increases
acid properties - ANS-1. Materials that ionize whilst delivered to water
2. Acids react with metallic that are chemically active to produce H2
three. Acids affect the colors of acid-base indicators
4. Acids neutralize bases
5. Dilute acids have a bitter taste
ALWAYS ADD ACID TO WATER
acid-base titration - ANS-when a acknowledged acid or base is introduced to an unknown base
or acid until it reaches its give up factor. This makes use of a preferred technique to decide the
awareness of every other solution (molarity). It is a form of volumetric evaluation
,acid to base or base to acid
acidic salt - ANS-salt of sturdy acid and susceptible base. It is simple in water
acidic solution - ANS-H+ > OH-
activation power - ANS-min. Quantity of kinetic electricity wanted for the collision of reactant
particles to result in a chemical reaction.
Alkali metals - ANS-institution 1A
alpha decay - ANS-radioactive nucleus emits an alpha particle, a brand new nucleus effects
the mass quantity of the new nucleus is 4 much less than that of the initial nucleus
the atomic number is decreased by way of 2
alpha particle decay - ANS-238U -----> 4He + 234Th
92 2 90
amorphous stable - ANS-atoms haven't any set sample and organized randomly
EX. Glass
amphiprotic - ANS-substance that could act as both an acid or base
anhydrous - ANS-hydrated crystal with water eliminated
aqueous solution - ANS-water is the solvent
arrhenius acid - ANS-in water produces H+
arrhenius base - ANS-in water produces OH+
atom - ANS-smallest part of an element that consists of three subatomic particles
atomic mass range - ANS-protons plus neutrons
atomic wide variety - ANS-variety of protons in atom
Avogadro's Law - ANS-same volumes of gases at the identical temperature and pressure
comprise the identical range of molecules
, background radiation - ANS-radiation that comes shape herbal sources to which dwelling
organisms are exposed on a continuing basis
balancing nuclear equations - ANS-in a balanced nuclear equation, the sum of the mass
numbers and the sum of the atomic numbers for the nuclei of the reactant and the products
should be same
barometer - ANS-device that measures atm pressure
base - ANS-places OH1- into answer instead of H1+ like an acid
base homes - ANS-1. Bases are electrolytes
2. Bases motive indicators to turn a characteristic shade
3. Bases neutralize acids
four. Water solutions of bases taste bitter and feel slippery
five. Bases emulsify fats and oils
bases in family merchandise - ANS-used to clean, remove grease, and to open drains
susceptible bases: window purifier - NH3
bleach - NaOCl
laundry detergent - Na2CO3, Na3PO4
toothpaste and baking soda - NaHCO3
baking powder, scouring powder, Na2CO3
lime for lawns and agriculture, CaCO3
laxatives and antacids, MgOH2, AlOH3
strong bases: drain purifier or oven cleaner, NaOH
fundamental salt - ANS-salt of a vulnerable acid and sturdy base. Basic salt is acidic in water
simple answer - ANS-H+ < OH-
beta decay - ANS-an electron emitted from the nucleus
forms when a neutron in the nucleus breaks down
beta particle decay - ANS-234Th ----> 234Pa + 0e
90 ninety one -1
binary compound - ANS-compounds wherein 2 elements are present , metallic and non metal -
nonmetal modifications to ide
binary molecule - ANS-1st word : prefix and full call
second word : prefix and stem and ide
