Answer:
d. n H2(g) = 0.034 mol
Explanation:
- 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
2 - Na - 2
4 - H - 4
2 - O - 2
∴ n Na(s) = 0.068 mol
⇒ n H2(g) = ( 0.068 mol Na(s) )( mol H2(g) / 2 mol Na(s) )
⇒ n H2(g) = 0.034 mol
Answer:
There is nothing attached to this question so I unfortunately cannot help you
Explanation:
The pressure unit is in atmospheres or atm. To confirm this from the ideal gas equation:
R = VP/nT
plugging in the standard values of pressure, temperature and molar volume,
R = (22.4L/mo)l(1atm)/(273.15K) = 0.0821
Combustion is the reaction
Answer:
Bears
Explanation:
because starch is heavy and it requires a lot of oxygen in an environment. so having starch in an environment with less oxygen could probably cause fatigue
