Answer:
structure of a muscle cell
I can't see the picture, but in general, I believe it is in dropping from the first energy level above the ground state, to the ground state.
Answer:
C
Explanation:
Because nothing is left at the end of the reaction.
The balanced chemical reaction is written as:
<span>NaOH + HCl → NaCl + H2O
We are given the amount of sodium hydroxide to be used up in the reaction. This will be the starting point for the calculation.
2.75 x 10^-4 mol NaOH ( 1 mol H2O / 1 mol NaOH ) ( 18.02 g H2O / 1 mol H2O ) = 4.96 x 10^-3 g H2O</span>
I'm pretty sure your answer should be CaCl2. Hope this helps! =^-^= (if I need to explain more just let me know.)
