I guess examples of solid and gas???? You have to be more descriptive.....
The propane undergoes a combustion reaction (combustion reactions are reactions in which a substance reacts with oxygen and burns).
To calculate the number of moles of propane, we use the molar mass of propane, which is 44.0 g/mol.
To convert mol C3H8 into mol CO2, we use the molar ratio between the two substances. The molar ratio is seen by the coefficients in front of the each substance in the reaction, so the ratio of C3H8 to CO2 is 1 to 3, with 3 moles of CO2 produced for every mole of C3H8 reacting.
To convert mol CO2 into molecules of CO2, we use Avogadro's number:
There are 6.022 × 10²³ molecules per mole of any substance:
Answer:
b
Explanation:
by using formula
a=(v-u)/t
where a= acceleration
v = initial velocity = 10 m/s
u= final velocity =50 m/s
t = time taken = 2s
Answer:
Supersaturated.
Explanation:
Hello there!
In this case, according to this solubility chart, we infer that for NH3, the solubility starts at 90 grams of NH3 that are soluble in 100 g of water at 0 °C and ends in about 8 g in 100 g of water at 100 °C for a saturated solution.
However, since we are asked for the solubility of NH3 at 20 °C, we can see that, according to the table and the curve for NH3, about 52 g of NH3 are soluble in 100 g of water; thus, for the given 60 g of NH3, we will say that 8 grams will remain undissolved, and therefore, this solution will be supersaturated.
