Monroe, Livingston were forced? by Congress to offer up to $2 million to purchase the east bank of the Mississippi; Jefferson secretly advised them to offer over $9 million for Florida and New Orleans. Napoléon initially resisted U.S. offers, but changed his mind in 1803
Explanation:
Answer:
The hydrogen gas is prepared in the laboratory required zink granules, dilute sulphuric acid or dilute hydrogen chloride, flask or woulfe’s bottle, and thistle funnel. by the downward displacement of water because it is a gas lighter than water
Reaction:
Zn (s)+2HCl (aq) →ZnCl2(aq)+H2(g)
Zn (s)+H2SO4(aq)→ZnSO4(aq)+H2(g)
The zinc granules are taken in a flask or Woulfe’s bottle and It is connected with the delivery tube to a water trough containing water. Dilute sulphuric acid is poured slowly from the thistle funnel. The hydrogen gas is released and collected in a gas jar by by the downward displacement of water as H2 gas lighter than water
Question Continuation
1. Mercury goes through a full cycle of phases
2. Moon rises in east, sets in west each day
3. Stars circle daily around north or south celestial pole
Answer:
The true statements are are (2) and (3)
2. Moon rises in east, sets in west each day.
From all part of the earth, we can see and observe the moon only that the stars move in parallel to the horizon in the north pole.
3. Stars circle daily around north or south celestial pole.
The relative position of starts are always altered because of the earth's rotation
While (1) does not really occur as seen from Earth
1. Mercury goes through a full cycle of phases
We can see the mercury from the Earth but in its whole form not in its phases.
Answer:
The correct solution is Option d (when rocks develop joints or fractures
).
Explanation:
- Porosity is observable from descriptive samples taken. The drawbacks of receivable dams are that this is impossible to make true reflection temperature measurements, specific side-wall concrete samples while being often valuable can also result in poor coverage as well as dependence on log-derived porosity seems to have become the standard.
- As porosity rises, too much wind needs to pass further through most of the shelterbelt, which would be to say the less significant decrease in wind direction.
Some other available scenarios have no connexons with the particular circumstance. So this seems to be a reasonable option.
