Answer:
Which class r u in hmm ? Tell me okay
Cl2 is the right answer since the molecule is composed of two chlorines.
Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
Answer:
Reactants starts the chemical reaction and gives right to the product either by thermal decomposition or in the presence of a catalyst.
Explanation:
Reactants and products contain the same atoms, but they are rearranged during the reaction, so reactants and products are different substances.
Answer:
893K=620 °C
Explanation:
PV=nRT
P=nRT/V
P= (1 mol* 0.0821* 298K)/15L P=1.63 atm
T=PV/nR
T=(1.63 atm*45 L)/(1 mol*0.0821)
T= 893K=620 °C
