Answer 1

Возим книжку и учи  там всё написано понятно 

Answer 2

It looks like you're asking for help with writing out the equations for a series of chemical reactions and identifying the types of reactions based on the number and composition of the reactants and products. Let's break this down step by step.

Writing the Equations for the Reactions

The reactions you've mentioned are: 1. Lithium (Li) to Lithium Oxide (Li2O) 2. Lithium Oxide (Li2O) to Lithium Hydroxide (LiOH) 3. Lithium Hydroxide (LiOH) to Lithium Sulfate (Li2SO4)

Now, let's write out the balanced chemical equations for each of these reactions.

1. Lithium (Li) to Lithium Oxide (Li2O) The balanced chemical equation for this reaction is: ``` 4Li + O2 -> 2Li2O ```

2. Lithium Oxide (Li2O) to Lithium Hydroxide (LiOH) The balanced chemical equation for this reaction is: ``` Li2O + H2O -> 2LiOH ```

3. Lithium Hydroxide (LiOH) to Lithium Sulfate (Li2SO4) The balanced chemical equation for this reaction is: ``` 2LiOH + H2SO4 -> Li2SO4 + 2H2O ```

Types of Reactions

Now, let's identify the types of reactions based on the characteristics of the reactants and products.

1. Lithium (Li) to Lithium Oxide (Li2O) This is a combination reaction because two or more substances combine to form a single product.

2. Lithium Oxide (Li2O) to Lithium Hydroxide (LiOH) This is a neutralization reaction because an acid and a base react to form a salt and water.

3. Lithium Hydroxide (LiOH) to Lithium Sulfate (Li2SO4) This is a double displacement reaction because the positive and negative ions of two ionic compounds exchange places to form two new compounds.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
