Answer:
chemical
Explanation:
A chemical change is irreversible and leads to the formation of new products.
Rusting occurs as a result of an irreversible chemical reaction between iron, oxygen and moisture. Rusting is the oxidation of iron when exposed to oxygen and moisture.
The rusting of iron is an electrochemical process in which water serves as the electrolyte and iron serves as the anode. The rusting of iron leads to the formation of hydrated iron III oxide (rust) usually seen an brown flakes that surround a rusted iron material.
Answer:
D. 0.36 g
Explanation:
When a gas is collected over water, the total pressure is the sum of the pressure of the gas and the pressure of the water vapor.
Ptotal = Pwater + PN₂
PN₂ = Ptotal - Pwater = 730 torr - 23.76 torr = 706 torr
We can find the mass of N₂ using the ideal gas equation.
Answer:
Barium and Chlorine
Explanation:
Ionic bonds are formed between metals and non metals where the metals lose electrons and become positively charged and the non metals gain electrons and become negatively charge. The opposite charges cause them to be attracted to each other and Bond. The only metal in those options above is Barium. Therefore an ionic bond will be formed between Barium and Chlorine.
