Answer:
Explanation:
We must convert formula units of Zn(ClO₃)₂ to moles and then to grams of Zn(ClO₃)₂.
Step 1. Convert formula units to moles
Step 2. Convert moles to grams
Answer:
Water and oxygen
Explanation:
The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust
Answer:
By making observations and doing experiments
Answer:
548.089 J
Explanation:
-The molar mass of copper is 63.546 grams.
-We obtained the mass of 0.762 moles of copper:
-We apply the specific heat formula to calculate the amount of heat released:
Hence, the amount of heat released is 548.089 J
I think the correct answer is C. Neutrons do not affect how atoms bond due to their neutral charge which makes it so that they don't affect the movement of electrons at all (chemical reactions occur when electrons are transferred/shared). Neutrons due however have a mass similar to that of a proton which means they contribute to the mass of the atom. Neutrons also effect the stability of the nucleas as shown in atoms that have radioactive isotopes. I hope this helps. Let me know if anything is unclear.
