Answer:

<em>Water</em>

Explanation:

This looks like a proverbial question, so I'll try and answer it as best as I can

Th mixture of 'hydrogen and oxygen came pouring out' to give water. Water is a liquid that 'drips and dribbles and it comes poring from a spout'

The question is talking about the reaction between hydrogen and oxygen to give water; a form of liquid as the by-product.

The reaction involves one atom of oxygen reacting with two atoms of hydrogen with an hydrogen bonding in-between to give a molecule of water.

Also note that a spout is a stream of liquid issuing from somewhere with great force. So the answer is <em>water.</em>
