Be sure to answer all parts.The combustion of a 40.0−g gaseous mixture of H2 and CH4 releases 3766 kJ of heat. Calculate the amo
Svetach [21]

Answer:H2=11.4g

CH4=28.6g

Explanation:The complete combustion of the two gases can be represented by a balanced reaction below

1. CH4 +2O2___CO2+2H2O

2.2H2+O2___2H2O

Combining the two we have CH4 +2H2+3O2___

CO2+4H2O

Since the mixture contains 40gof CH4 and 2, therefore 20g of CH4 and 8g of H2 combines.

Calculated from their molecular Mass i.e CH4 12+4×2)=20 and 2H2= 2×2×2=8g

Mass of CH4=20/28×40=28.6g

2H2=8/28×40=11.4g

What do oxygen, silicon, and selenium have in common? How might this relate to their organization on the periodic table?
Sonbull [250]

Answer:

They all belong to the p block in the periodic table

Explanation:

Let us examine the electronic configuration of each element;

Oxygen - [He] 2s2 2p4

Silicon - [Ne] 3s2 3p2

Selenium - [Ar] 4s2 3d10 4p4

A common thread that joins all the elements listed above is that they all belong to the p-block in the periodic table. They could be collectively referred to as p-block elements.

Read the sentence.
ExtremeBDS [4]

Answer:

The correct answer is "reveal the structures".

Explanation:

The predicate is the part of the prayer that tells us what the subject is doing. In this prayer "The Fossils" is the subject, so we must seek the action that develops from the subject. That action is that the fossils "reveal the structures". In this way, we can find the simple predicate of this sentence.

The solubility of sodium hydrogen carbonate in water 20 degrees is 9.6 g/100 g h2o.
d1i1m1o1n [39]

We can see from the details below that, the value of the solution's molality is 1.14 mol/Kg.

<h3>What is solubility?</h3>

The term solubility has to do with the quantity of solute that is able to dissolve in a given quantity of solvent. We have the solubility of the sodium hydrogen carbonate in water at 20 degrees as 9.6 g/100 g h2o.

Number of moles of sodium hydrogen carbonate = 9.6 g/84 g/mol = 0.114 moles

Number of moles water = 100 g /18 g/mol = 5.55 moles

Mole fraction of sodium hydrogen carbonate is obtainable by the use of the relation;

0.114 moles/0.114 moles + 5.55 moles

= 0.02

Molality of the solution = 0.114 moles/0.1 Kg = 1.14 mol/Kg
