what is the difference between soul and spirit
Spirit is a force behind our life either holy or evil, the is what represents the body after its dead
Depends. There are a few forms of the spirit (your thoughts, the word of God, the angels..etc) Your soul is you. The sum total of you physically and mentally.
Genesis 2:7 KJV
And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Scripture does not say God put anything in us except the breath of life. There's no "spirit" in us (besides mind which scripture calls spirit)
There is nothing that represents us when we die. When you're dead you're asleep till the resurrection.
