Answer:
The volume of 4.92 grams of hydrogen gas at STP is 9.105 litter.
Explanation:
We know that, the molecular weight of hydrogen gas 
= 
.
Moles of hydrogen gas = 
moles.
At STP, 1 mole of hydrogen gas = occupies 22.4 litter
So, 2.46 mole of hydrogen gas = occupies 
litter.
Hence, the volume of 2.46 grams of hydrogen gas at STP is 9.105 litter.
Answer:
The electrons are supplied by the species getting oxidized. They move from anode to the cathode in the external circuit. The external battery supplies the electrons. They enter through the cathode and come out through the anode
1. Rust, or Fe2O3, is a Chemical Compound.
2. Carbon is a Chemical Element found as C on the periodic table.
3. Apple Juice is a Heterogeneous Mixture, as it is uniform throughout. If it wasn't uniform, there would be yucky lumps in your apple juice :)
If I helped you out, I would greatly appreciate if you went through my other answers I gave you and gave them the brainliest answer :)
Answer:
Knowing that boron has an atomic mass of 10,811 means that all boron isotopes on average weigh 10,811 u.
Explanation:
The atomic mass of an atom is the mass of the atom measured in u (unified atomic mass unit), although we can also express it as Da (Dalton's unit)
Atomic mass refers to the average mass that all isotopes of that element have.
When we speak of isotopes we are referring to the element itself but with a different number of neutrons, which makes it modify its mass number.
