What mass of silver nitrate is needed to fully react with 10.0 grams of calcium chloride?
The mass of silver nitrate is 30,6 g.
How many grams of hydrogen are needed to produce g of water according to 2h2 plus o22h2o?
This value is 0,2 g hydrogen.
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
What is the percentage by mass of hydrogen in ammonia?
Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%
What mass of calcium bromide is needed to prepare 250 ml of a 2.50M?
The answer is 124,93 g (for the anhydrous CaBr2).
According to the law of conservation of mass how many atoms of calcium can react to produce more calcium?
According to the law of conservation of mass how many atoms of calcium can react to produce more calcium?
How many grams of sodium needed to produce 2.0 mole of hydrogen gas?
The needed mass of sodium is 91,659 g (for 2 moles H2).
How many grams of calcium carbonate are needed to produce 55.0 L of carbon dioxide at STP?
mass of CaCO3 = 246 grams
How many grams of H2 are needed to produce 14.59g of NH3?
The atomic mass of hydrogen is 1.008 and that of nitrogen is 14.007. Therefore, the ratio of the mass of hydrogen to the total mass of NH3 must be 3(1.008)/[14.007 + 3(1.008)] = 0.17756. The mass of hydrogen in the stated amount of ammonia must therefore be 14.59(0.17756) = 2.591 g, to the justified number of significant digits.
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
What information is needed to calculate the mass of calcium oxide that can be produced frrom 4.7 kg of calcium carbonate?
molar masses of calcium, carbon, oxygen
What is the word equation of calcium with hydrochloric acid?
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
What is mass of calcium carbonate is to be decomposed to obtain 4.4 gram of carbon dioxide in the reaction caco3-cao plus o2?
The equation given shows that each formula mass of calcium carbonate produces one formula mass of CO2. The gram formula masses of calcium carbonate and carbon dioxide are 100.09 and 44.01 respectively. Therefore, to produce 4.4 grams of carbon dioxide, 4.4(100.09/44.01), or 10 grams of calcium carbonate, to the justified number of significant digits, are needed.
What mass of silver nitrate is needed to fully react with 10.0 grams of calcium chloride?
The mass of silver nitrate is 30,6 g.
The size of the force needed to produce acceleration of an object is determined by the objects what?
Mass ?
Why do you need 40 grams of calcium and 32 grams of sulfur to make 72 grams of calcium sulfide?
From the periodic table, calcium has a molar mass of 40.078g/mol and sulfur has a molar mass of 32.065g/mol. The formula for compound formed from calcium and sulfur, calcium sulfide is CaS. The molar mass of CaS is 72.143. So, if you round the numbers, 40g of Ca + 32g of S will produce 72g of CaS.
Can three atoms of calcium react to produce six atoms of calcium?
No: That would violate the law of conservation of mass and require creation of new atoms, which no chemical reaction can achieve.
