Question

pls give the Correct answer pls​

Answer 1

Answer:

Reactant Atoms. Product Atoms

ii). H- 2, I- 2. H -1, I- 1

iii). Al- 1, O- 2. Al -2, O- 3

iv). Ca- 1, C- 1, O- 3. Ca- 1, C- 1, O-3

Answer 2

(ii) $\sf\:H_{2}+I_{2}~\longrightarrow~HI$

Here ,

$\bf\small\: Reactant~atoms~:~$$\tt\:H-2~and~I-2$

$\bf\small\: Product~atoms~:~$$\tt\:H-1~and~I-1$

‎

(iii) $\sf\:Al_{2}+O_{2}~\longrightarrow~Al_{2}O_{3}$

Here ,

$\bf\small\: Reactant~atoms~:~$$\tt\:Al-1~and~O-2$

$\bf\small\: Product~atoms~:~$$\tt\:Al-2~and~O-3$

‎

(iv) $\sf\:CaCO_{3}~\longrightarrow~CaO+CO_{2}$

Here ,

$\bf\small\: Reactant~atoms~:~$$\tt\:Ca-1~,~O-3~and~C-1$

$\bf\small\: Product~atoms~:~$$\tt\:Ca-1~,~C-1~and~O-3$
