PH of a solution is -ln[H3O+]
so,in case of A pH=3 or,-log[H3O+]=3 or,[H3O+]=10^-3
in case of B pH=6 pr,-log[H3O+]=6 or, [H3O+]=10^-6
so,hydronium ion concentration in solution A /the hydronium ion concentration in solution Z
=10^-3/10^-6
=1000
2)
Ca(OH)2+2 HNO3=Ca(NO3)2+2 H2O
so the answer is 2.
Answer:
When dry ice is exposed to warm air, a gas called carbon dioxide is produced through a process called sublimation
Explanation:
The reaction that results from this is:
H2O + CO2 --> H2CO3
Stoichiometric ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.
therefore, we need 12 moles of water.
Answer:
they are eamples of chemical properties
Explanation:
flammibility is the chemical makeup of the element that makes it flamable and reactivitie is the chemical makeup of an element that is able to reacte to another element
Answer: The direction will be the opposite direction in the balanced force. The object stays at rest in the balanced force. The speed of the object continues to move in the same speed. And the net force acting will be zero.
