Update accounts.mdx

I propose 3 changes for clarity of the text:

Firstly, "The balance of ETH token in the account balance (unit in wei)." - There's a repetition of "balance" in this sentence. I revised  it for clarity: "The balance of ETH tokens in the account (unit in wei)."

Secondly, "The number of bytes in the contract bytecode." - I revised it for clarity: "The size of the contract bytecode in bytes."

And lastly, "In the high level..." - I revised it for clarity: "At a high level..."

 The account in Scroll contains the following fields:
 
 - `nonce`: A counter that indicates the number of transactions sent by the sender.
-- `balance`: The balance of `ETH` token in the account balance (unit in wei).
+- `balance`: The balance of `ETH` token in the account (unit in wei).
 - `storageRoot`: The root hash of the storage trie. Since Scroll uses the [zkTrie](/technology/sequencer/zktrie) for the storage trie, the `storageRoot` stores the Poseidon hash digest in a 256-bit integer.
 - `codeHash`: The Keccak hash digest of the contract bytecode.
 - `PoseidonCodeHash` (**new field**): The Poseidon hash digest of the contract bytecode in a 256-bit integer.
-- `CodeSize` (**new field**): The number of bytes in the contract bytecode.
+- `CodeSize` (**new field**): The size of the contract bytecode in bytes.
 
 ## State
 
 The state of a blockchain is a collection of account data. The _state trie_ encodes account data and their corresponding addresses to a [Merkle tree](https://en.wikipedia.org/wiki/Merkle_tree) data structure. The root of tree, or the state of the blockchain, is a cryptographic digest of all the account data contained in the tree.
 
-Ethereum uses a data structure called [Patricia Merkle Trie](https://ethereum.org/en/developers/docs/data-structures-and-encoding/patricia-merkle-trie/) for both the state trie and the storage trie that stores the key-value entries stored in a smart contract. In Scroll, we replace the Patricia Merkle Trie by a more zk-friendly data structure, called zkTrie, for both state trie and storage trie. In the high level, the zkTrie data structure is a sparse binary Merkle tree with the [Poseidon hash](https://eprint.iacr.org/2019/458.pdf), a zk-friendly hash function. The [zkTrie](/technology/sequencer/zktrie) document describes more details about this data structure.
