Is gallium oxide acidic or basic?
Gallium is amphoteric (i.e., it reacts either as an acid or as a base, depending on the circumstance), reacting with sodium and potassium hydroxide solutions to yield a gallate and hydrogen gas.
What is gallium used for?
It has important uses in Blu-ray technology, mobile phones, blue and green LEDs and pressure sensors for touch switches. Gallium readily alloys with most metals. It is particularly used in low-melting alloys. It has a high boiling point, which makes it ideal for recording temperatures that would vaporise a thermometer.
How to calculate the number of NO2 molecules?
2for each two NO as required by the balanced equation. The right box (products) contains eight NO2 molecules. The number of NO2molecules on the right equals the number of NO molecules on the left as the balanced equation requires. Counting the atoms, we find eight N atoms in the eight NO molecules in the box on the left.
