Answer: Since this is merely a Physical Change, it is improper to write it as a chemical equation.
<h3>
Answer:</h3>
True, the reaction given is an example of a synthesis reaction
<h3>
Explanation:</h3>
- Synthesis reactions are reactions where two or more substances combine to form a single compound.
- The reaction 2NO(g) + O₂(g) → 2NO₂(g) is an example of a synthesis reaction.
Other types of chemical reactions may include;
- Decomposition reaction in which a compound is broken down into smaller compounds or individual elements.
- Replacement reaction where reactive elements replace other less reactive elements in their salts.
- Precipitation reactions in which soluble salts reacts to form a precipitate and a soluble salt as a result of exchange of anions and cations.

Explanation:
First, we have to calculate the number of moles of H2SO4 in the solution:
V=60 mL = 0.06 L
c=5.85 mol/L
n=V×c=0.06×5.85=0.351 mol
Then we need to find the molar mass of H2SO4:
2×Ar(H) + Ar(S) + 4×Ar(O) =
=2 + 32 + 64 = 98 g/mol
Finally, we need to find the mass of H2SO4:
m=0.351 × 98 = 34.398 g
The correct option is SILT.
Terminal velocity refers to the constant speed with which an object fall under the force of gravity. The smaller the weight of the object, the faster will be the rate of falling of the objects. From the options given above, it is silt that has the smallest particle size and the right texture to achieve the highest terminal velocity.<span />
