<span>If the solution feels slippery and has a pH of 12 that means the solution is a base. Common base solutions are soapy water, bleach, oven cleaner and liquid drain cleaner.</span>
Answer:- Volume decreases by a factor of 1.15.
Solution:- At constant pressure, volume of the gas is directly proportional to the the kelvin temperature.
The equation is written as:
where, 
is the volume at initial temperature 
and 
is the volume at final temperature 
.
Temperature must be in kelvins. So, let's convert both the temperatures to kelvin.
To convert degree C to kelvin we add 273.
So, = 100 + 273 = 373 K
= 50 + 273 = 323 K
The equation could also be written as:-
= 1.15
From here we could say that the volume decreases by a factor of 1.15.
For example if the initial volume is 1 L then final volume will be 
that is 0.87 L.
Answer:
Baking soda mixed with Vinegar
Explanation:
This is a chemical reaction that I have seen in my daily life. Vinegar is acidic while baking soda is a base. The 2 mix together to form carbonic acid and sodium acetate from sodium and bicarbonate ions.
1. solute is the substance that is being dissolve,while solvent is dissolving medium
2.saturated is solution that contain maximum amount of solut that capable of being dissolve and supersaturated is solution that contain less amount or medium of solut that capable being dissolve : example vinger
3. is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction. For example, two molecules of hydrogen would be written as 2 H2, and two molecules of water would be written 2 H2O . yes it's can be change only in caseWhen you balance an equation you can only change the coefficients
