Assuming that all gases are at STP, find the volume of nitrogen dioxide gas that could be produced from 71.11 dm3 of diatomic nitrogen gas. Diatomic oxygen gas reacts with calcium metal to form calcium oxide solid (CaO). Write the balanced reaction equation.
Calcium oxide reacts with water in a coination …
Calcium oxide reacts with water in a coination reaction to produce calcium hydroxide: CaO (s) + H 2O (l) → Ca(OH) 2 (s) In a particular experiment, a 2.00-g sample of CaO is reacted with excess water and 2.14 g of Ca(OH) 2 is recovered. Answer: The answer to
Calcium - Wikipedia
The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.

Copper - Wikipedia
Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another

WATCH: Cooled-Down Caesium in Water Is The Most …
Caesium is a curious alkali metal known to be extremely reactive and super-explosive when it comes into contact with water - even at temperatures of -116 C (−177 F). As part of a short video series capturing some of the most beautiful chemical explosions, the team at SciencePhotoLibrary decided to film a sample of caesium reacting with water using a high-speed camera.
