Answer:
ZnCl2
H2
Explanation:
The products of the given reaction is:
ZnCl₂ and H₂
The two species are the products of the chemical combination
- This reaction is a single displacement reaction
- Because Zn is more reactive, it displaces hydrogen from the acid
- This forms a hydrogen gas
- We know this because Zn is higher in the activity series.
Answer:
boiling point is an example of a chemical property because chemical property is not changing the matter if physical property means it can change the matter or shape
Answer:
Explanation:
Step 1
The mass percent of MgCO3 in the original mixture is calculated as shown,
Step 2
Masses of MgCO3 and CaCO3 is 24g; Moles of carbon dioxide produced from Magnesium carbonate and Calcium carbonate are.
Step 3
Adding and equating the moles of Carbon dioxide results in,
Step 4
Percent mass of MgCO3 in the sample is calculated as,
I’m confused what are you asking exactly?
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
