Answer:
South American
Explanation:
When you look at a map of plates, only South American forms a boundary with the African plate out of those specific plates
Answer:
1813.74g
Explanation:
Given parameters:
Number of moles of radon = 8.17moles
Unknown:
Mass of radon = ?
Solution:
To solve this problem, we use the expression below:
Number of moles = 
Molar mass of radon = 222g/mol
Now insert the parameters and solve;
Mass of radon = Number of moles x molar mass
= 8.17 x 222
= 1813.74g
The answer is B.
When a volcano spews out smoke and gasses, there very harmful to the atmosphere and geosphere, the gasses it spews out is, hydrogen sulfide, sulfur dioxide, carbon monoxide, and carbon dioxide.
I hope this helps!
The balanced chemical equation of the reactions given is as follows:
- 2LiHCO3 -----> Li2CO3 + H2O + CO2
- 2 N2 + 5 O2 -----> 2 N2O5
- MgBr2 + KOH -----> KBr + Mg(OH)2
- Mn + 2 CuCl -----> 2 Cu + MnCl2
- 8 Zn + S8 -----> 8 ZnS
- 2 NaOH + H2SO4 -----> 2 H2O + Na2SO4
- 2 K + 2 H2O -----> 2 KOH + H2
- C5H12 + 8 O2 -----> 6H2O + 5 CO2
- 2 KOH + H2CO3 -----> 2 H2O + K2CO3
- C4H802 + 6 O2 -----> 4 H20 + 4 CO2
- 16 Al + 3 S8 ---> 8 Al2S3
<h3>How to balance chemical equations</h3>
Balancing of chemical equations is the process of adding numerical coefficients in front of moles of reactants and products to ensure that the moles of atoms of elements of the reactants is equal to the moles of atoms of products formed.
