From the given balanced chemical reaction,
C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
18 g x (32 g oxygen / 12 g carbon) = 48 grams.
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
If the bill is counterfeit and the paper is wood-based, the iodine in the pen solution will react with the starch and leave a dark brown or black mark.
Answer:
2. What must be done to carbon dioxide gas to change it to a solid?.
Carbon dioxide is a gas by using a metal to solidify it
3. Which is colder, dry ice or carbon dioxide gas?
Carbondioxide gas
If dry ice is placed in water, we see bubbles rise.
4. These bubbles are made of
gaseous substance in the gaseous state.
5. What happens to the size of the dry ice as the bubbling goes on?
the size of the dry ice reduces as a result of conversion of solid to liquid form
Explanation:
Answer:
Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them.
