PRACTICE Balance the following equations using the appropriate coefficients. Remember that balancing one element may
temporarily unbalance another. You will have to correct the imbalance in the final equation. Check your work by
counting the total number of atoms of each element—the numbers should be equal on the reactant and product
sides of the equation. Remember, the equations cannot be balanced by changing subscript numbers!
1. Al + O2 + Al2O3
2. CO + H2 + H2O + CH4
3. HgO + Hg + O2
4. CaCO3 + CaO + CO2
5. C + Fe2O3 → Fe + CO2
6. N2 + H2 + NH3
7. K + H2O → KOH + H2
8. P + O2 + P205
9. Ba(OH)2 + H2SO4 → H2O + BaSO4
10. CaF2 + H2SO4 → CaSO4 + HF
11. KCIO3 → KC1O4 + KCI

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

i'll try what topic lol

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
