Water reacts with sodium metal to produce sodium hydroxide and hydrogen gas, along with heat and light. What are the reactants in this chemical
reaction?
A. Sodium metal and water
B. Sodium hydroxide and hydrogen gas
C. Sodium metal and sodium hydroxide
o
D. Sodium metal and hydrogen gas

A

Explanation:

sodium metal react with water ,the result will be sodium hydroxide plus hydrogen gas

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
