Answer:
Explanation:
1. Take in account the sulfuric acid at STP:
2. Density is expressed as the ratio between the mass and the volume of a substance so:
Solving for m:
3. Replace values:
For the equation to be balanced, the Atom's coefficient on the left side and the right side of the equation has to be equal
so, the answer would be :
Br2 + S2032- + 5H20 -- > BR2- + 2S02- + H+
Hope this helps
A shows the physical features of the land
Explanation:
A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.
- A topographic map is made up of series of contour lines.
- The contour lines are lines that joins places of equal elevation.
- All places on the contour lines have the same elevation.
- Using the contour lines, we can understand the landforms in an area.
- Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
- Most topographic maps are used as base maps for making other maps.

Considering the definition of molarity, the molar concentration is 0.294 
.
Molarity reflects the concentration of a solution indicating the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units .
In this case, you know:
- amount of moles of solute= 0.250 moles
- volume= 0.850 L
Replacing in the definition of molarity:
Solving:
molarity= 0.294
Finally, the molar concentration is 0.294 .

Answer:
The dam disrupts the river wildlife and ecosystem.
Explanation:
Though it is believed that using the dam as a power generation or hydroelectric power supply generates no greenhouse gases, it, however, has many disadvantages which make it deemed not suitable or sustainable for use in the contemporary time.
Majorly, the top reason why more hydroelectric dams are not built is that "the dam disrupts the river wildlife and ecosystem."
Also, it affects the water quality and other use of water for humans such as recreational use.
There is also a possible chance of dams producing methane; a greenhouse gas through the organic materials in the water that is rotting.
