Answer:

D. [NO₂]²/[N₂O₄]

Explanation:

The equilibrium constant expression for a reaction is products over reactants. Since NO₂ has a coefficient of 2, it will become an exponent.

So, it would be:

[NO₂]²/[N₂O₄]

Hope that helps.

Toluene, c6h5ch3, is a liquid compound similar to benzene, c6h6. it is the starting material for other substances, including tri
babymother [125]
Toulene = 35.6 g 
Benzene = 125 g = 0.125 kg
 Molecular weight of Toluene C6H5CH3 = 92.1g/mol
 Moles of toulene = 35.6 g / 92.1 g/mol = 0.3865 mol

 Now the molarity of the toulene in the given solution = 0.3865 / 0.125 = 3.092 m 
 Molarity of C6H5CH3 = 3.092 m

What would happen if the oceanic plates stoped moving
Ket [755]

Answer:

But without plate tectonics, Earth will simply stop making new ones. The mountains we have now would erode over a few million years, turning into low, rolling hills. Our planet would eventually flatten out, with more land ending up underwater. On the bright side, there'd be fewer natural disasters.

Explanation:

that is what would happen

Answer:

Matter cannot be created or destroyed in chemical reactions.

Explanation:

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions

What is the total amount of heat required to completely melt 347 grams of ice at its melting point
jolli1 [7]
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q = ml, where m is the mass of substance and l is its latent heat of fusion. For ice, the latent heat of fusion is 334 joules per gram. Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
