The third option, 2,2,1,2
Answer:
MnO2 M n O 2 is an ionic substance without any oxo-anions, therefore its name has the -ide ending.
Answer:
liquid
Explanation:
Gas has very low density but spreads fast. Solid has high density.
I’m pretty sure it’s none of the above cause I’m googling it a bunch and and it say you use the dideoxy method
Answer:
52.1 degrees C
Explanation:
We need to use the equation: q = mCΔT, where m is the mass in grams, C is the specific heat capacity, and ΔT is the change in temperature.
Here, m = 10 g and q = 125 J. The heat capacity of iron is about 0.461 J/(g * C). And, our initial temperature is 25. So:
125 J = (10 g) * (0.461 J/(g * C)) * (T_f - 25)
Solving for T_f (final temp), we get: 52.1 degrees C
Hope this helps!
