Answer:
Pushing the plunger reduces the volume and forces particles closer together. The particles inside the bubble are pushed into a smaller volume, so the plastic surrounding them gets smaller (crumples) to surround the smaller volume. 2.

Answer:
7.04 g
Explanation:
Let's consider the reaction in the last step of the Ostwald process.
3 NO₂(g) + H₂O(l) → 2 HNO₃(aq) + NO(g)
The molar mass of HNO₃ is 63.01 g/mol. The moles corresponding to 6.40 g are:
6.40 g × (1 mol/63.01 g) = 0.102 mol
The molar ratio of NO₂ to HNO₃ is 3:2. The reacting moles of NO₂ are:
0.102 mol HNO₃ × (3 mol NO₂/2 mol HNO₃) = 0.153 mol NO₂
The molar mass of NO₂ is 46.01 g/mol. The mass corresponding to 0.153 moles is:
0.153 mol × (46.01 g/mol) = 7.04 g
Answer:
try a dude ummm yes ok yeah
The answer is A. the attraction between atoms that enables the formation of chemical compounds.
Answer:
The quantities of electrical charge that are they can produce are the same
Explanation:
The quantity of electrical charge produced by an electrochemical cell is given by
Number of moles of electrons × Faraday's constant.
since the number of moles of electrons involved in the two electrochemical reactions are the same (2 moles of electrons each) then the charge that they can produce will also be the same.
Hence the answer.
