Help Mr. Henderson write his dramatic laboratory safety rules! Select ALL the sentences that use conditionals correctly.
The correct answers are If you mix baking soda and vinegar in a sealed tube, it creates a messy volcano. and If you forget your safety goggles, you will not participate in the explosion experiment.
The first correct sentence is a Zero Conditional (If + present simple, present simple), which is used for scientific facts or general truths.
The second correct sentence is a First Conditional (If + present simple, will + base verb), which describes a real, possible situation in the future.
"If you will touch..." is incorrect because we do not typically use "will" in the "if" clause of a first conditional.
"we will walked..." is incorrect because "will" must be followed by a base verb, not a past tense verb.
