Answer:
Solution : When sodium hydrogen carbonate is added to acetic acid then carbon dioxide (CO2) gas is evolved. CO2 trun s lime water milky it is a non supporter of combustion and is absorbed by strong alkalies like NaOH. Sodium hydrogen carbonate when added to acetic acid evolves a gas.
Explanation:
Chemically the ethanoic acid reacts with the sodium hydrogen carbonate to form carbon dioxide gas and water. The carbon dioxide gas produced rushes away from the water. This is seen as bubbles.
Sun is 4.6 billion years old.
There is enough hydrogen for another 5 billion years in the Sun.
Answer:
Attached below is the required diagram .
Explanation:
During the reaction of resorcinol and ethyl acetoacetate there is the production of a transesterification product, and this transesterification product is produced in other to increase the electrophicilty of the carbonyl center.
Attached below is the required diagram .
Answer:
60.87 ft/s
Explanation:
Speed is defined as a ratio between the distance traveled and time. Given a total distance of:
Let's convert it into feet first of all using the conversion factor:
We obtain:
Now let's convert the given time into seconds knowing that:
Then:
Now let's find the speed:
From equation;
P1V1=P2V2
V2=P1V1÷P2
since P2=380mmHg
now;1atm=760mmHg
how about 380mmHg is equal to how many atm?
380×1÷760=0.5atm
P2 now is equal to 0.5atm
back from equation;
P1V1=P2V2
V2=P1V1÷P2
V2=4.0atm×2.0L÷0.5atm
V2=16L
therefore V2=16L.
