When 84G of magnesium carbonate was heated 40G of magnesium oxide was collected why did the mas go down?
The decrease in mass is likely due to the release of carbon dioxide gas during the process of heating magnesium carbonate to form magnesium oxide. The gas escapes, leading to a decrease in the overall mass of the sample.
What does calcium carbonate do for the tooth?
Calcium carbonate helps to strengthen the enamel of the tooth by replenishing minerals that may be lost due to acids produced by bacteria in the mouth. It can also act as a mild abrasive that assists in removing plaque and stains from the teeth.
What is the equation to use to find mass of x lost by hydrate?
Weight of hydrated substance - weight of same material after desiccation.
What is calcium ionic symbol?
The ionic symbol for calcium is Ca^2+. It indicates that calcium has lost two electrons to achieve a stable electron configuration in its outer shell.
What is the ion formula of calcium?
The chemical symbol (not formula) of calcium is Ca.
How can you find the mass of Calcium Carbonate in a Tums Tablet in a chemistry lab?
To find the mass of calcium carbonate in a Tums tablet, you can weigh the tablet before and after a reaction that specifically targets the calcium carbonate. For example, if you react the tablet with hydrochloric acid to produce carbon dioxide gas, you can measure the mass lost due to the evolution of CO2 to calculate the mass of calcium carbonate present.

When you heat 0.80g of copper carbonate and you weigh it after cooling how come the mass didn't change?
Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
What does calcium carbonate do for the tooth?
Calcium carbonate helps to strengthen the enamel of the tooth by replenishing minerals that may be lost due to acids produced by bacteria in the mouth. It can also act as a mild abrasive that assists in removing plaque and stains from the teeth.
When cuso45h2o is heated in a crucible there is a loss of water how is the amount of water loss determined?
The amount of water loss from cuso4·5h2o can be determined by measuring the weight of the crucible and compound before and after heating. The initial weight represents the compound with water, and the final weight after heating will show the loss of water as the difference in weight. By subtracting the initial weight from the final weight, the amount of water lost can be calculated.
What is the equation to use to find mass of x lost by hydrate?
Weight of hydrated substance - weight of same material after desiccation.
Where does lost energy in a rheostat go?
It is lost in heating the resistive material of the rheostat.
How do you determine whether an unknown substance is a carbonate or bicarbonate when comparing the mass of the substance before and after heating?
when bicarbonate is heated it decomposes into the carbonate, one water and one carbon dioxide. it is this loss of mass that will enable you to determine the identity of the anion in your unknown. make balanced equation. go moles to grams on each side using atomic mass then divide mass of carbonate by mass of bicarbonate.... aka product by reactant and if larger then 100 then it's a carbonate and subtract 100 from your answer and that is how much you gained... if smaller than multiply by 100% and then subtract your answer from 100 and that is how much you lost...
A vitamins expiration date has passed It was supposed to contain 500 mg of Calcium but it has lost 325 mg of Calcium How many mg of Calcium is left?
175
What is the smallest particle of calcium that has the same chemical properties of calcium?
The smallest particle of calcium that retains the chemical properties of calcium is the calcium ion (Ca2+). This ion has lost two electrons from a calcium atom, giving it a positive charge while maintaining the chemical characteristics of calcium.
Why egg become rubbery when soaked in vinegar?
Oh, dude, when you soak an egg in vinegar, the acidic nature of the vinegar breaks down the calcium carbonate in the eggshell, causing it to dissolve. This leaves the egg white and yolk unprotected, making them more susceptible to overcooking. So, the egg becomes rubbery because it's lost its shell's support, like trying to walk in flip-flops that are two sizes too big.
You are 15 and you just lost 8lbs in a month is that healthy?
That depends on your present weight and how you lost the weight, if you lost it by not eating properly that is not healthy.
