Answer:
Below
Explanation:
The balanced equation for h202 = h20 + 02 is:
2H2O2 = 2H20 + O2
The coefficients would be 2
The balanced equation for Na + I2 = NaI is:
2Na + I2 = 2NAI
The coefficients would be 2
Hope this helps! :)
Answer:
Yes.
Explanation:
Yes, I think that Barcelona has large temperature changes throughout the year because Barcelona has minimum temperature of 33°F in winter season and maximum temperature of 88°F in summer season.
