What is the minimum amount of calcium carbonate in a limestone rock?
Limestone is composed of at least 50% calcium carbonate (CaCO3) by weight. Therefore, the minimum amount of calcium carbonate in a limestone rock would be 50%.
What does calcium bicarbonate decompose to give?
Calcium bicarbonate decomposes when heated to give calcium carbonate, water, and carbon dioxide gas. This reaction occurs at temperatures above 50°C and is used in various applications, such as in the removal of temporary water hardness.
How do you prepare 50 percent solution of potassium carbonate?
To prepare a 50% potassium carbonate solution, you would mix equal parts of potassium carbonate powder with water. For example, to make 100mL of 50% solution, you would mix 50g of potassium carbonate with 50mL of water. Stir until the powder is fully dissolved to achieve the desired concentration.
How many grams of KCl to make 50 mL of 2.45 M KCl?
To calculate the grams of KCl needed, first calculate the moles of KCl required using the molarity formula. Then, convert moles to grams using the molar mass of KCl, which is approximately 74.55 g/mol.
What mineral makes up limestone?
The mineral that makes up limestone is calcite, which is a form of calcium carbonate. It is typically composed of the remains of marine organisms such as coral and shells that have accumulated over time and solidified into rock.
What is the minimum amount of calcium carbonate in a limestone rock?
Limestone is composed of at least 50% calcium carbonate (CaCO3) by weight. Therefore, the minimum amount of calcium carbonate in a limestone rock would be 50%.
What would be the total number of atoms in ten molecules of calcium carbonate?
This number is 50 atoms.
What is an igneous rock composed of calcium carbonate?
An igneous rock composed of calcium carbonate is called carbonatite. It typically forms from the melting of carbonate-rich minerals in the Earth's mantle, resulting in a rock dominated by minerals such as calcite, dolomite, and siderite. Carbonatites are rare and are known for their unusual mineral compositions.
How many moles of HCl are in 50 ml of 4.0 M HCl?
To find the moles of HCl, first calculate the millimoles of HCl in 50 mL: 4.0 mol/L * 50 mL = 200 mmol. Then convert millimoles to moles by dividing by 1000: 200 mmol / 1000 = 0.2 moles of HCl. Therefore, there are 0.2 moles of HCl in 50 mL of 4.0 M HCl.
How much calcium nitrate can be obtained by reacting 50 g of calcium carbonate with nitric acid?
CaCO3+ 2 HNO3 = Ca(NO3)2+H2CO3Molecular Weight 100 206Weight's) 50 xAnswer:x = 206*50/100 = 103 g
How do you convert 50 milli molar of sodium acetate into grams?
we know, 50 mM = 50/1000 moles per litre = 0.05 moles no. of moles = weight in grams/ weight of one mole weight of one mole of sodium acetate (CH3COONa) = 83g per mole no. of moles = 50/1000 = 0.05 moles thus weight in grams = 0.05*83 = 4.15 g
How many atoms are there in 50 gram of calcium carbonate?
In 50 grams of calcium carbonate, there are approximately 6.02 x 10^23 atoms. This is because one mole of any substance contains Avogadro's number of particles, which is 6.02 x 10^23 atoms for elements or molecules.
What are the characteristics of limestone islands?
it contains at least 50% calcium carbonate it has cracks and joints it is permeable (allows water to past through)
50g of limestone were heated strongly so that all of the limestone turned into the products?
CaCO3 -----> CaO + CO2 - Calcium carbonate has a MWt of 100 so 50 g is half a mole so 0.5 moles of CaO MWt 56 and so 28g produced and Carbon Dioxide is MWt 44 so 22g produced.
How do you find the mol of Ca 50g?
Calcium is 40g per mole (according to the periodic table,) so 50/40=1.25 moles.
How many moles of solute are in 50 mL of a 12 M HCl solution?
To find the number of moles of solute in the solution, first, calculate the amount of HCl in grams using the formula: moles = molarity x volume (in liters). Then, convert the grams of HCl to moles by dividing by the molar mass of HCl (36.46 g/mol).
What salts are responsible for bone structure?
The salt used to construct bone is ...Hydroxyapatite (calcium phosphate and calcium carbonate)Other than the salt, which is 50% of the bone, it is also 25% water, and 25% collagen fibers, which are what gives bone its tensile strength.
