Answer:

711\ \text{mmHg}

Explanation:

P_{total} = Total pressure = 751 mmHg

P_{water} = Vapor pressure = 40 mmHg

P_{gas} = Pressure of gas

The total pressure in a system is given by Dalton's law

P_{total}=P_{gas}+P_{water}\\\Rightarrow P_{gas}=P_{total}-P_{water}\\\Rightarrow P_{gas}=751-40\\\Rightarrow P_{gas}=711\ \text{mmHg}

The partial pressure of the hydrogen is 711\ \text{mmHg}

Element x reacts with oxygen to produce x2o3 in an experiment it is found that 1.0000 g of x produces 1.1xxx g of x2o3 what is t
8_murik_8 [283]

Since X is 1 g, therefore O must be 0.1 g. Therefore:

moles O = 0.1 g / (16 g / mol) = 0.00625 mol

 

We can see that for every 3 moles of O, there are 2 moles of X, therefore:

moles X = 0.00625 mol O (3 moles X / 2 moles O) = 0.009375 mol

 

Molar mass X = 1 g / 0.009375 mol

<span>Molar mass X = 106.67 g/mol</span>

Write a balanced chemical equation for the standard formation reaction of solid sodium hydrogen carbonate Write a balanced chemi
4vir4ik [10]

Answer:

Na(s) + C(s, graphite) + 1/2 H₂(g) + 3/2 O₂(g) → NaHCO₃(s)

Explanation:

The standard formation reaction is the synthesis of 1 mole of a substance from its elements in their most stables forms under standard conditions. The balanced chemical equation is:

Na(s) + C(s, graphite) + 1/2 H₂(g) + 3/2 O₂(g) → NaHCO₃(s)
