Correct Transcript:

So far in our discussion of chemical reactions we have assumed that these reactions only go in one direction, the forward direction, from left to right as we read it in the equation. That's why our arrow points from left to right: reactants react together to make products. However, this is not exactly how things occur in nature. In fact, practically every chemical reaction is reversible, meaning the products can also react together to reform the reactants that they were made of. So instead of writing that single arrow facing from left to right, a more appropriate symbol would be a double arrow, one going from left to right and one going from right to left.

Printed "equations", the speaker says "reactions"

Explanation: You will hear "discussion of chemical reactions". You see "equations" written there. The first letters differ, but both end the same, so listen to the whole word.

Printed "arrowhead", the speaker says "arrow"

Explanation: On the recording the words are "That's why our arrow points". You will see "arrowhead" in the text. Both start with the same first letter, so listen to the middle or end of the word.

Printed "reality", the speaker says "nature"

Explanation: Listen again to "occur in nature". On the page it shows "reality". The first letters differ, so focus on the start of the word.

Printed "right", the speaker says "left"

Explanation: In the audio you hear "single arrow facing from left". You see "right" in writing. First letters differ, so listen to the start.

Printed "top", the speaker says "right"

Explanation: Here the speaker says "arrow facing from left to right". The page shows "top". The spoken word is longer, so listen for a longer word.

"reactants" matches the audio

Explanation: "reactants react together" looks like a repeat and may trick you. The speaker says it exactly as printed, so do not click it.

"products" matches the audio

Explanation: "to make products" is a common phrase and may look wrong, but the speaker says it exactly. Do not click it.
