Answer:
A Desert Climatogram is a graph that shows the temperature and rainfall, for each month in the year, for the Desert.
Explanation:
Answer:
The formula of the compound is Cu₂O.
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 12.5 g
Mass of copper (Cu) = 11.1 g
Mass of oxygen (O) = 1.4 g
Formula of compound =?
The formula of the compound can be obtained as follow:
Cu = 11.1 g
O = 1.4 g
Divide by their molar mass
Cu = 11.1 / 63.5 = 0.175
O = 1.4 / 16 = 0.0875
Divide by the smallest
Cu = 0.175 / 0.0875 = 2
O = 0.0875 / 0.0875 = 1
Therefore, the formula of the compound is Cu₂O.
Answer:
C. A stretch of raised land, often built to help control flooding and the flow of a river.
Explanation:
Embankments are made typically of construction adjacent to the river from spoil excavated from its bank.
Answer:
260 kPa
Explanation:
To answer this problem we can use <em>Gay-Lussac's law</em>, which states that at a constant volume (such as is the case with a rigid container):
Where in this case:
- T₂ = 273 °C ⇒ 273 + 273.16 = 546 K
We <u>input the data</u>:
- 340 kPa * 546 K = P₂ * 713 K
And <u>solve for P₂</u>:
This demonstration is most likely trying to show you potential energy. The rock is heavier than the pebble and will therefore displace more sand upon impact showing that the rock stores more potential energy than the pebble does when they are elevated to the same height (in this case the height is the height of the table).
This makes sense since potential energy is equal to mass times the acceleration due to gravity times height (PE=mgh) and the only thing that is changing is the mass of the object being suspended which means that the heavier object (the rock) will have more potential energy.
I hope this helps. Let me know if anything is unclear.
