The mass of the surroundings:
An example is if a reaction took place in a sealed container, the mass of whatever is formed eg. Precipitate, gas, etc. + the mass of the solution that is left over at the end of the reaction (assuming there is some left) will be the same as the initial solution you started with.
The total mass of the products is equal to the the mass of the reactants. The reactants are what we start with to do the reaction. The product (or products) is the end result.
It is possible that some of the products may change state (and seem to disappear as a gas for instance), but the total mass has not changed, it has just changed to a different state. For example when you burn wood, oxygen gas reacts with the wood and you get carbon dioxide gas, along with maybe carbon monoxide and some other gasses, as well as some small particles which are mixed in (which makes the smoke). So when it stops burning, you see that there is just a little charcoal and ash remaining, but the rest of the mass escaped from the area of observation.

∙ 14y agoIn any chemical reaction, mass is conserved, which is to say, there is the same amount of mass before the reaction as their is after the reaction; mass is not created or destroyed. In nuclear reactions we can see the conversion of mass to energy, but this doesn't happen to any noticeable degree in chemical reactions. That doesn't mean that you have the same amount of fuel, of course, just that you have the same amount of mass. The fuel turns into combustion products which, depending upon what fuel you are burning, are likely to include carbon dioxide and water, among others. If you are burning hydrogen, then water is the only combustion product. Gasoline produces lots of combusion products.

Does you mass always stay the same no matter what?
Yes, no gas is given off, therefore the mass of conversation will stay the same.
How much mass is given off as gas during a chemical reaction?
The amount of mass given off as gas during a chemical reaction depends on the stoichiometry of the reaction and the molar mass of the gas produced. It can be calculated using the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas.
When you heat a cool substance does the mass or volume change?
No, the mass and volume stay the same but the shape changes. Changes in state never change it's mass but if it changes to gas, the volume is unmeasurable.
What mass of water decomposes to make 4 grams of hydrogen gas and32 grams of oxygen gas how do you know?
In chemistry, the outcome of a reaction must have the same mass as the initial state. This means that if you have 32g of oxygen and 4g of hydrogen, you just have to add the numbers to discover the original mass (in this case, 36g).
How could a chemist find out how much mass is given off as gas during a chemical change?

When a gas or liquid is heated its mass decreases increases or stay the same?
There's no reason for the mass of anything to depend on its temperature.
What supports the idea that mass is conserved in a reaction that produces a gas as a product?
Trapping the gas and measuring its mass...

Why there is loss in mass reaction of baking soda and acetic acid?
Mass isn't lost, it just escapes as a gas

Why wont gas stay in a cup?
Gas will stay in a cup. If the gas is denser then air, it will settle into the cup and stay there in much the same way that a liquid will. If the gas is close to the same density as the air, or lighter, it will float away and mix with the air.

Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
If solution A has a mass of 60 g and solution B has a mass of 40 g when they are mixed a chemical reaction occurs in which gas is produced if the final mass of the mixture is 85 g what mass gas produc?
the total is 100, since there is 85 the gas must be 15 g
Which has more mass in a chemical reaction out of solid liquid or gas?
Its irrelevant. Could be any one of them.
