Consider the reaction. 2HF(g) +

H2(g) + F2(g)

At equilibrium at 600 K, the concentrations are as follows.

[HF] = 5.82 x 10-2 M

[H2] = 8.4 x 10-3M

[F2] = 8.4 x 10-3M

What is the value of Kea for the reaction expressed in scientific notation?

O 2.1 x 10-2

102.1 x 102

1.2 x 103

0 1.2 x 10-3

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

you didnt put any of the following

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
