Answer:
selenium forms 2- ion (Se2− S e 2 − )
It is to create energy that the cell can use. it takes in oxygen to break down food molecules to get cellular energy for cell function
Answer:
The balanced chemical equation is P₄ (s) + 5O₂ (g) → P₄O₁₀ (s)
Explanation:
In order to balance the chemical equation, you first need to see what's out of balance.
In this case our Oxygen is not balanced, so in order to make the two the same, we need to see what coefficient we need to add to the compounds to balance the problem.
So, adding a coefficient of 5 to the O₂ will result in an equal number of oxygen on both sides.
Answer:
Electrons
Explanation:
The particles found in the cloud surrounding the nucleus of an atom are the electrons.
These particles occupies the bulk volume of the atom.
- Electrons were first discovered by J.J Thomson from his experiment on the gas discharge tube.
- These particles carries a negative charge on them.
- They have a mass of 9.11 x 10³¹kg
