2Mg+ O₂= 2MgO
The charge of Mg is+2 and the charge of Oxygen is -2. 2 oxygen atoms will have a charge of -4 so the Mg atoms have to equal +4. A coefficient of 2 for the Mg atoms will balance it out
Answer:
N2 + 3H2 + 2NH3
Explanation:
I'm assuming you're balancing the chemical equation
Answer:
1
Explanation:
Oxygen is a pure substance therefore it is only made up of one kind of atom
Answer:
Final temperature = 25.71°C
Explanation:
By using formula Q=mcΔT
let's say x is final temperature
950 = 150.1 × 4.18 × ( x - 24.2 )
950 = 627.418 × ( x - 24.2)
950 = 627.418x - 15183.5156
627.418x - 15183.5156 = 950
627.418x = 950 + 15183.5156
627.418x = 16133.5156
x = 16133.5156 / 627.418
x = 25.71 °C
So...the final temperature is 25.71 °C
