Answer 1

As there are a lot of questions I have mostly written only answers of multiple choice questions and single line answers for other questions. Hope you are able to understand it.

1- c- Molecular compound

2-c- Molecular compound

3-b- sulfide ion

4-c- NO2-

5-a- combination

6-d- all of the above

7-d- all of the above

8- e- change a subscript of the formula of the equation is not balanced

9- d- all of the above

10-c- 2.51

11-c- 180.17 g/mol

12-d- 30.20%

2-The harmful effects of carbon monoxide are.

1)Breathing CO can cause headache, dizziness, vomiting, and nausea.

2)If CO levels are high enough, you may become unconscious or die.

3)Exposure to moderate and high levels of CO over long periods of time has also been linked with increased risk of heart disease.

CH4 + 3/2 O2 -> CO + 2H2O
