Question

1.C+O2=2.Ca+O2=3.H+O2=4.Si+O2=​

Answer 1

Ответ:

1.)2C+2O2=2C20

2)2Ca+2O2=2Ca2O

3)2H+2O2=2H20

4)2Si+2O2=2Si2o

Answer 2

Ответ:

Объяснение:

C + O2 = CO2

2Ca + O2 = 2CaO

2H2 + O2 =t°c= 2H2O

Si + O2 = SiO2

Answer 3

It seems like you've provided a series of chemical reactions, but they're not balanced properly. Let's balance them:

1. C + O2 → CO2
2. Ca + O2 → CaO2
3. H2 + O2 → H2O
4. Si + O2 → SiO2

Now, let's balance the equations:

1. C + O2 → CO2 Balanced: 2C + O2 → 2CO2

2. Ca + O2 → CaO2 This reaction doesn't appear to be balanced properly.

3. H2 + O2 → H2O Balanced: 2H2 + O2 → 2H2O

4. Si + O2 → SiO2 Balanced: Si + 2O2 → SiO2

If you meant something different, please provide more context or clarify your question!
