Answer:
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

Answer:
What is the main purpose of the curiosity rover ?
Explanation:
Curiosity's mission is to determine whether the Red Planet ever was, or is, habitable to microbial life. The rover, which is about the size of a MINI Cooper, is equipped with 17 cameras and a robotic arm containing a suite of specialized laboratory-like tools and instruments.
This one is an oxidation-rdcution equation:
<span>H2 + F2 → 2HF
How can you tell?
If the oxidation states of the atoms in the reactans are different from the oxidation states of the same atoms in the products then it is an oxidation-reduction reaction.
Both atoms H and F in the reactants have oxidation states 0.
That is a basic rule: any atom alone or bonded to the same kind of atom has oxidation state 0.
The oxidation states in HF are: H: +1, and F: -1.
So, the H increased its oxidation state, which is that ii is oxydized ; while F reduced its oxidation state so it is reduced.
Answer: H2 + F2 ----> 2HF

Answer:-
Option 2
Explanation:-
In a multi step reaction, the overall reaction is as fast as the slowest step only.
So the rate of a multistep reaction is the same as the rate of its slowest step.
The gas phase reaction was found to be second order wrt NO2.
So the slowest step must have 2 NO2 since the dependence is second order on NO2.
It was also found to be zero order wrt CO.
So the slowest step must not contain any CO since it’s presence has no effect on the reaction (zero order).
Among all options, only number 2 meets the two criterion
Thus the steps are
NO2 + NO2 – NO3 + NO (Slow)
NO3 + CO – NO2 + CO2 (Fast)
