C H 3 C O O H
<span>Answer:
When sodium nitrate (NaNO3) is dissolved in water, the resulting solution is neutral. NaNO2 = Na+ + NO2-
NO2- + H2O = HNO2 + OH-
The solution is basic
NaNO3 = Na+ + NO3-
NO3- is the conjugate base of the strong acid HNO3 will not react with water so the resulting solution is neutral</span>
Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals.
<u>Explanation</u>:
- Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable).Mainly most of them are solids. Ta, Os and Rh are all metals with a same platinum group.
- Tantalum (Ta) with a atomic number 73 is a lustrous transition metal which is highly corrosive resistant. It is mainly used in making electronic equipment.
- Rhodium (Rh) is a chemical element with atomic number 45 is a rare, silvery white,hard and corrosive resistant metal. Osmium (Os) with a atomic number 76 is a hard, brittle bluish-white transition metal.
Answer:
There is no deacceleration.
Explanation:
Let's check relation between velocity and acceleration


So as velocity graph is going up acceleration is going up
Those flat lines on graph shows constant acceleration .
Curve lines up shows instantaneous acceleration.
If the graph is going down then it can be deacceleration .
Note :-No F is present in graph
