Given the chemical equation: 2 Ca + O_2 to 2 CaO. If 2 moles of CaO are formed in this reaction, then 2 moles of O_2 must have reacted. State whether the statement is True or False. Burning of methane is an example of both redox reaction and combustion...
The defined BsonSchema trait defines a single function, bson_schema, which should/will return a Bson Document that is a valid JSON schema describing the structure of the implementing type. Example: #[macro_use] extern crate serde_derive; extern crate serde; #[macro_use] extern crate bson;...
There isn't any need for that in an embedded scripting language. Other "default" mistakes that almost every scripting language has had so far. For example, the exclusive use of floating-point numbers for arithmetic operations, even for integers. It's a well-known fact that floating-point ...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states...
Since there is an equal number of each element in the reactants and products of CO2 + H2 + O = H2CO3, the equation is balanced. Balance CO2 + H2 + O = H2CO3 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must...

Add 1 molecule of H2O to the product (right-hand) side to balance Oxygen: Zn(OH)2 + H2CO3 = ZnCO3 + 2H2O ReactantsProducts Zn 1 1 ✔️ O 5 5 ✔️ H 4 4 ✔️ C 1 1 ✔️ Step 3: Verify that the equation is balanced Since there are an equal number o...
Since there is an equal number of each element in the reactants and products of Al(OH)3 + 3H2CO3 = Al(CO3)3 + 3H2OH, the equation is balanced. Balance Al(OH)3 + H2CO3 = Al(CO3)3 + H2OH Using Inspection The law of conservation of mass states that matter...
Since there is an equal number of each element in the reactants and products of H2CO3 + Sr(OH)2 = 2H2O + CO3Sr, the equation is balanced. Balance H2CO3 + Sr(OH)2 = H2O + CO3Sr Using Inspection The law of conservation of mass states that matter cannot be created or d...
