Given:
Volume of KOH = 53.0 mL
Concentration of KOH = 0.320 M
Volume of HNO3 = 28.0 mL
Concentration of HNO3 = 0.250 M
Balanced Equation:
KOH + HNO3 ===> KNO3 + H2O
0.320 0.250 0 0
H2O ===> H+ + OH-
Solve for the concentration of OH-
The moles of butane gas and oxygen gas reacted if 2.50 moles of H2O is produced is calculated as below
the equation for reaction
2C4H10 +13 O2 = 8CO2 +10 H2O
the moles of butane (C4H10) reacted calculation
by use of mole ratio between C4H10: H2O which is 2 : 10 the moles of C4H10= 2.50 x2/10 = 0.5 moles of C4H10 reacted
The moles of O2 reacted calculation
by use of mole ratio between O2 : H2O which is 13:10 the moles of O2
= 2.50 x 13/10= 3.25 moles of O2 reacted
Answer:
Pb(s) + N2(g) + 3O2(g) --> Pb(NO3)2
Explanation:
Answer: The Note
Explanation: Neurotransmitters are endogenous chemical substances that transmits signals through a NEUROMUSCULAR JUNCTIONS.
The signals are transmit from one NERVE CELL TO THE TARGET POINT such as Muscle cell,gland cell etc. Neurotransmissiom require the presence of synapse(the structure or medium through which neurosignals which can be an electrical or chemical signals to pass through).
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 <<<<
