Answer:
ionic salt MX2
Explanation:
Atoms from an element in group IIA are allowed to react with atoms from an element in group VIIA. What type of compound is likely to form
elements from IIA are alkali earth metals (M) and need to lose
2 e^1- to become stable as M^2+
elements from VIIA ar halogens (X) and need to gain 1 e^1-
to become stable so one M^2+ combines with 2 X^1- to make
an ionic salt MX2
Answer:
2 moles of oxygen
Explanation:
Basic Equation (given) :
2H₂ (g) + O₂ ⇒ 2H₂O (g)
- From this, we understand for every 2 moles of water, 1 mole of oxygen is needed
Taking the number of moles of oxygen and water in proportion :
Therefore, 2 moles of oxygen are required to make 4 moles of water.
Answer:
a. Bronze
