The size of calcium carbonate chips affects the surface area available for reaction with acids, which influences the rate of gas production, typically carbon dioxide. Smaller chips have a greater surface area relative to their volume, allowing for more frequent collisions with acid molecules and thus producing gas more rapidly. Conversely, larger chips have less surface area exposed, leading to slower gas production. Therefore, smaller chips generally result in a higher volume of gas produced over a given time period compared to larger chips.

How much volume of carbon dioxide is required to be bubbled through lime water to precipitate 20 gram of calcium carbonate?
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
How long does it take for calcium hydroxide to degrade back to calcium oxide by absorbing carbon dioxide from the atmosphere?
Calcium hydroxide can absorb carbon dioxide and become calcium carbonate; by heating calcium carbonate is transformed in calcium oxide. The time for these reactions depends on the temperature, pressure, volume of the reactants, amounts of reactants, the physical appearance, sometimes stirring etc. Please read a chemical kinetics book for more details and understanding of the chemistry.
What is concentration of 150 gm of calcium carbonate in 850 ml of water?
Concentration is 150 gm solute per 850 mL solvent: 150 g solute per (150g + 850g =) 1000 g solution = 15% (m/m) CaCO3, since 850 mL is equal to (rounded) 850 grams.However calcium carbonate is rather INsoluble (smaller than 0.15 g/100 mL, about 0.15%) so this answer is physically impossible to achieve.If the question was mistyped and could have been 150 mg(= milligram, not gm = gram) per 850 mL, THEN the answer would have been 0.15 g per (850g + 0.15g =) 850 g solution which is (100%*0.15/850=) 0.018% CaCO3
What volume of CO2 gas will be evolved at ntp by heating 7.3 g of magnesium hydrogen carbonate?
The volume is 1,1 mL.
Does increasing the concentration of an acid affect the volume of gas released?
Yes but might depend on the reaction, assuming you mean the production of hydrogen from a reaction of an acid and metal, the higher concentration of acid would mean there are more H+ ions in the solution therefore there would be a higher volume of gas produced.
When a metal carbonate reacts with an acid carbon dioxide is always produced what factors might affect the volume of gas produced?
The mass of the carbonate used.
What is the volume of CaCO3 if you have a molarity of 75.5 and 15 g CaCO3 What is the answer and how did you get it?
Calcium carbonate is not soluble in water.
What one way that the rate of the reaction between sulphuric acid and calcium carbonate can be followed?
One way to follow the rate of the reaction between sulphuric acid and calcium carbonate is by measuring the volume of gas produced over time. As the reaction proceeds, carbon dioxide gas is released, so monitoring the increase in gas volume at regular intervals can provide information about the reaction rate.
What experiment can you do to find out how much calcium carbonate there is in limestone?
To determine the amount of calcium carbonate in limestone, you can perform a titration using hydrochloric acid. By reacting a known mass of limestone with hydrochloric acid, you can measure the volume of acid required to neutralize the calcium carbonate. This information can then be used to calculate the amount of calcium carbonate present in the limestone sample.

What volume of water would be needed to dissolve a piece of chalk having a mass of 7 grams?
The volume of water needed to dissolve a 7 gram piece of chalk would depend on the solubility of the chalk in water. Typically, chalk (calcium carbonate) is sparingly soluble in water. If we assume complete dissolution, the approximate volume of water needed can be calculated using the molar mass of calcium carbonate and the density of water.

A rolaid tablet contains calcium carbonate if 44.55 ml of 0.448 M hydrochloric acid is required to neutralize one tablet how many milligrams of calcium carbonate are in a rolaids tablet?
44.55 ML solution x 1L/1000ML X 0.448M HCL/1L solution X 1mole CaCO3/2 mole HCL= 0.0099792 M CaCO3 0.0099792 M CaCO3 x 217gCaCO3/1 mole CaCO3= 2.17g CaCO3 X 1000MG/1g=2170 mg of calcium carbonate are in a rolaids tablet?
How can calcium Hydroxide be made from Limestone?
Calcium hydroxide can be made from limestone by heating the limestone (calcium carbonate) while heating the carbon dioxide is given off . this turns the limestone into calcium oxide and now if you add a little water the calcium oxide will turn into calcium hydroxide Hope it helped you....:) The process can be shown in a flow diagram called the 'limestone reaction cycle'
When 0.1 mol of calcium reacts with 880 g of water 2.24 L of hydrogen gas form at STP How would the amount of hydrogen produced change if the volume of water was decreased to 440 mL?
The amount of hydrogen produced will not change since the production of hydrogen gas in the reaction is determined by the number of moles of calcium reacting, which remains constant at 0.1 mol. The volume of water does not affect the amount of hydrogen gas produced as long as the stoichiometry of the reaction is maintained.
How many ml of gas would be produced if 2 spoons of baking soda reacted with 1.5 spoons of calcium chloride?
The reaction between baking soda and calcium chloride would produce carbon dioxide gas. The volume of gas produced would depend on the reaction conditions (temperature, pressure, etc.). To accurately determine the volume of gas produced, you would need to perform the reaction and measure the gas volume using appropriate techniques.
How is urine calcium 24 hour calculation done?
To calculate urine calcium over 24 hours, a patient collects all urine produced in a 24-hour period in a designated container. At the end of this period, the total volume of urine is measured. A sample from this collection is then analyzed in a laboratory to determine the calcium concentration, which is typically reported in milligrams per liter. The total calcium excretion is then calculated by multiplying the calcium concentration by the total urine volume in liters.
