E has indeed the lowest freezing point.
Answer:
29.76ºC
Explanation:
The melting point is a physical property of the matter it doesn't change as you slice the gallium into three different parts. Thus, it's the same value 29.76ºC

PLS MAKE ME BRAINLEST!
Answer:
B there are a different number of electrons in an ion compared to a neutral atom
The balanced reaction between NaOH and HCl is as follows
NaOH + HCl ----> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
molar mass of NaOH is 40 g/mol
number of moles =
therefore number of NaOH moles - 4.00 g / 40 g/mol = 0.100 mol
since molar ratio of HCl to NaOH is 1:1
number of HCl moles required = 0.100 mol
Molarity of HCl is 1.0 M
this means that a volume of 1 L contains 1.0 mol
therefore volume containing 0.100 mol - 0.100 mol / 1.0 mol/L = 0.10 L
volume of HCl required = 100 mL
