Find 1 mol
6C = 12*6 = 72
12H=1*12 = 12
O6 = 16*6 = 96
Total = 180 grams
0.98 mol
0.98 * 180 = 176.40 My answer would have to go out to 176.40
Note: anyone responding will use rounded numbers for the atomic mass. All periodic tables have variations in them. Use your periodic table to get the better atomic mass.
Answer
176.40 g C6H12O6 <<<<
Answer:
The first 5 are exothermic reaction because heat is in product means heat is evolved or given out.
And last no reaction shows that heat is required so last reaction is endothermic reaction.
Explanation:
And heat is evolved in exothermic reaction and heat is absorbed in endo thermic reaction
Identical twins will have the e physical features such as hair color and eye color, because they were formed from the exact same egg and sperm. Fraternal twins are formed from two different eggs and sperm, so those twins will look different from each other.
Hope this help :))
Answer:the initial composition of the reactants is
40cm^3 of CH4
40cm^3of H2
100cm^3 of H2O
Explanation:
Balanced reaction is
CH4 +H2+5/2O2______
CO2 +3H2O
Excess KOH at room temperature absorbs CO2 whose volume is given by 40cm^3 i.e the volume by which the solution decreases
So using Gay lussac combining ratio which states that gases combine in volumes that are in simple ratio to each other if gases.
Since CO2 in the equation is 1 mole
Means 1mole represent 40cm^3
So CH4:H2:O2 are in ratio of 1:1:5/2=(40:40:100)cm^3 respectively.
