Answer:
fe3o4+4h2 - 3fe + 4h2o
therefore coefficient is 4
The answer is A. planning a hiking trip
A topographical map would not help studying plant growth over time unless you are looking for a better altitude to plant said plants.
A topographical map would not help studying rainfall for one year unless your location was <em>really</em> so high or low that it affected your weather
And most of all, a topographical map would not be useful for planning a cuise across the Atlantic Ocean because the elevation of the sea is zero!
A topographical map <em>would</em> be useful for planning a hiking trip because there are many factors and details that a hike should have. Which includes height, distance, paths, and elevation.
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Ca2+ and Cl-, you will get the neutral compound to be CaCl₂.
Answer:
1. cells
2. energy
3. pre-existing cells by division
Explanation:
Answer:
0.0100M of AgNO3 contains 0.0100M of Ag+
Explanation:
AgNO3 when ionized yields Ag+ and NO3-. This means that the amount of AgNO3 in solution is equivalent to the amount of Ag+ and NO3- in that same solution.
1M of AgNO3 solution produces 1M of Ag+
1M of AgNO3 solution produces 1M of NO3-
This occurs because of the complete ionization of AgNO3 in solution, allowing complete dissolution of the compound.
