Answer: The mass concentration for a solution containing 45 g of calcium carbonate for 100 
is 0.045 M.
Explanation:
Given: Mass of calcium carbonate = 45 g
Volume = 
Convert into L as follows.
Moles of calcium carbonate (molar mass = 100 g/mol) is as follows.
Molarity is the number of moles of solute present in a liter of solution.
Hence, molarity (or mass concentration) of given solution is calculated as follows.
Thus, we can conclude that the mass concentration for a solution containing 45 g of calcium carbonate for 100 is 0.045 M.
To get radius, divide the diameter into 2. 3.6÷2 = 1.8 cm
Stoms or tornadoes cause about ten times more damage a year, on average, as hurricanes. Storms often cause more complete destruction than hurricanes because of their large size, long-term duration, and their varied potential for damage to property.
Storms can be very severe storms, hurricanes often last a long time, cover most of the earth and cause great damage. The wind from the strongest calves is stronger than the one from the strongest storms.

Answer:Consider the reaction N2(g) + 3H2(g) =; 2NH3(g). If hydrogen gas is added to this system at equilibrium, will the reaction shift towards reactants
Answer:
1 and 3
Explanation:
The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.
