A tea kettle holds on average about 1.7-2 Liters of water. So the answer should be 2 Liters
Answer:
The Lydia Bourouiba is recorded is around more than the 100 sneezes and coughs cases.
Explanation:
Lydia Bouroubia was a mathematical physicist who does experiments on sneezes and coughs. She was a leading expert in coughs and sneezes. Sneezing is a phenomenal activity that occurs in our body to excrete the dust particles and germs.
The disease also spread through it. Lydia thought that her research will help people related to their health. It will help in stopping epidemics in public. It is a type of outbreak of disease at a bigger level in the public.
Answer:.603moles
Explanation:do given over 1 so 66.38 over 1 then multiply by 1 over 110.035344(the atomic mass of KMnO) and then you get the answear
Answer:
b. The weak base of an alkaline buffer will accept hydrogen protons when a strong acid is added to the solution
d.The conjugate acid of an alkaline buffer will donate hydrogen protons when a strong base is added to the solution.
Explanation:
A buffer is a solution that resist pH change, it shows minimal change upon addition of small amount of strong acid or strong base. An alkaline buffer will have a basic pH, above 7. It is made by mixing a weak base and its salt with a strong acid. An example of an alkaline buffer is carbonate-bicarbonate buffer that is prepared using varying amount of anhydrous sodium carbonate and volume of solution of sodium bicarbonate to get pH range between 9.2 to 10.7
Within the buffer,the salt is completely ionized while the weak base is partly ionized. on addition of acid, the released protons will be removed by the bicarbonate ion to form sodium carbonate; on addition of base, the hydroxide ion released by the base will be removed by the hydrogen ions to form water and the pH remains relatively the same
Hydrogen is 8, Oxygen is 1, and Carbon is 3
