Predict the products of below reaction, and whether the solution at equilibrium will be acidic, basic, or neutral.
kati45 [8]

Answer: The product of the given reaction is HNO_{3} and the solution at equilibrium will be acidic.

Explanation:

When two or more chemical substances react together then it forms new substances and these new substances are called products.

For example, 3N_{2}O_{5} + 3H_{2}O \rightarrow 6HNO_{3}

This shows that nitric acid (HNO_{3}) is the product formed and it is an acidic substance.

Hence, the solution at equilibrium will be acidic in nature.

Thus, we can conclude that the product of the given reaction is HNO_{3} and the solution at equilibrium will be acidic.

One way to heat a gas is to compress it. a gas at 1.00 atm at 25.0°c is compressed to one tenth of its original volume, and it r
Tanzania [10]

(p1)(V1)/(T1) = (p2)(V2)/(T2)
(1.00 atm)(V) / (273 + 25K) = (40.0 atm)(V/10) / (273 + T)
273 + T = (40.0)(1/10)(273 + 25K) / (1.00)
T = 919°C
