Question #9b627 + Example - Socratic
Changes in state are physical changes. Let's take water as an example. H2O. In the gaseous state, we sometimes call it steam or water vapor; it's chemical formula is still H2O. In the liquid state and in the solid state (ice), the chemical formula is H2O. In a physical change, the original substance is still there - it may be in a different state or shape, but there are no new …

What is a double replacement reaction? How are they ... - Socratic
The clue lies in the name itself. Double displacement reactions occur when two ionic compounds react, or when an ionic compound reacts with an acid. It only occurs in liquids. There are 5 types of double displacement reaction, as shown below: Salt + salt = insoluble salt + salt Acid + carbonate = salt + H2O + CO2 Acid + base = salt + H2O Ammonium + hydroxide = salt + H2O …
What is the molar mass of water?? - Socratic
Each water molecule contains two hydrogen atoms (#M = "1.0079 g/mol"#) and one oxygen atom (#M = "15.999 g/mol"#). Therefore, the molar mass is:

What does the reaction of CO2 (g) + H2O (l) produce? - Socratic
How about this? > Step 1. The δ^"-" oxygen in a water molecule attacks the δ^"+" carbon in a "CO"_2 molecule. Step 2. A second water molecule deprotonates the newly-formed oxonium ion. Step 3 The newly formed hydronium ion transfers a proton to the negatively-charged oxygen atom that was formed in the first step.
