Question

H2O > H2 + O2 As + O2 > As2O5K + O2 > K2 O2Cu + O2 > CuOH2 +F2 > HFK + Cl2 > KCL​

Answer 1

$1) 2H_2O => 2H_2 + O_2\\2) 4As + 5O_2 => 2As_2O_5\\3) 2K + O_2 => K_2 O_2\\4) 2Cu + O2 => 2CuO\\5) H_2 +F_2 => 2HF\\6) 2K + Cl_2 =>2 KCl$

Answer 2

Ответ:

Объяснение:

2H2O = 2H2 + O2

4As + 5O2 = 2As2O5

2K + O2 = K2O2

2Cu + O2 = 2CuO

H2 + F2 = 2HF

2K + Cl2 = 2KCl

Answer 3

The chemical reactions you've provided are not balanced correctly. Let's balance each equation:

1. H2O > H2 + O2 This is already balanced.

2. As + O2 > As2O5 The balanced equation is: 4 As + 5 O2 > 2 As2O5

3. K + O2 > K2O The balanced equation is: 4 K + O2 > 2 K2O

4. Cu + O2 > CuO The balanced equation is: 2 Cu + O2 > 2 CuO

5. H2 + F2 > 2 HF The balanced equation is: H2 + F2 > 2 HF

6. K + Cl2 > KCl This is already balanced.

Now, the balanced chemical reactions are:

1. H2O > H2 + O2
2. 4 As + 5 O2 > 2 As2O5
3. 4 K + O2 > 2 K2O
4. 2 Cu + O2 > 2 CuO
5. H2 + F2 > 2 HF
6. 2 K + Cl2 > 2 KCl
