Correct answer is:
,,Atoms can react together, be separated from each other, or be rearranged via chemical reactions. "
:-) ;-)
Answer:
Sharing or covalent bonding is taking place.
Explanation:
The valence electron will be shared by both the atoms so that means that the election will move around both of the atoms.
I cant see the chemical reaction taking place, and what is the evidence to support it
Answer: 1.77 kg of manganese (IV) oxide reacts to produce 1.12kg of manganese metal.
Explanation:
The balanced chemical equation is:
To calculate the moles, we use the equation:
moles of manganese =
According to stoichiometry :
3 moles of is produced by = 3 moles of
Thus 20.4 moles of is produced by = of
Mass of (1kg=1000g)
Thus 1.77 kg of manganese (IV) oxide reacts to produce 1.12kg of manganese metal.
Answer:
56 L
Explanation:
We're dealing with a gas in this problem. We may, therefore, apply the ideal gas law for this problem:
We now that we have a constant pressure. Besides, R, the ideal gas law constant, is also a constant number. Let's rearrange the equation so that we have all constant variables on the right and all changing variables on the left:
This means the ratio between volume and temperature is a constant number. For two conditions:
Given initial volume of:
Convert the initial temperature into Kelvin:
Convert the final temperature into Kelvin:
Rearrange the equation for the final volume:
