Magnesium is divalent. This means that one magnesium atom needs to lose 2 electrons in order to become stable.
Chlorine, on the other hand, is monovalent. This means that one chlorine atom needs to gain one electron in order to become stable.
Based on this, one magnesium atom will combine with two chlorine atoms, where the magnesium loses two electrons, one for each chlorine.
The formula of the compound formed is: MgCl2
If they didn't wear gloves while treating patients then they could get the bacteria from the hands onto the patient and it could lead to an infection.
Answer:
D. CH₄(g) + H₂O(g) → CO(g) + 3H₂(g)
Explanation:
A rule of thumb is that there's an increase in entropy if there are more molecules in the products than in the reactants when there's no state change. The only given option where that takes place is option D., as there are two molecules in the reactants and 4 (1 of CO and 3 of H₂) in the products.
It’s d
