The answer is The Ca atom should transfer only one electron to Cl, and the second electron should be transferred to another Cl atom.
the lewis dot structure of calcium chloride is as shown in the image attached:
one atom of Ca is giving its two electrons to chlorine atoms so that it makes ionic bond with chlorine, it gets +2 charge, and two chlorine atoms will get -1 negative charge respectively that is overall the compound is neutral.
Answer: Heat of the solution = mass water × specific heat water × change in temperature
mass water = 260ml (1.00g/ml ) = 260g
specific heat of water = c(water) = 4.184J/ g°C
Heat change of water = final temperature - initial temperature
= 26.5 - 21.2
= 5.3 °C
H = 260 g ( 4.184J/g°C ) (5.3°C) = 5765J
Molar heat =
= 16473J/mol
Explanation: finding molar heat requires first to look at specific heat of water and the change of water temperature
Answer:
Explanation:
hello,
the combined gas law equation is given as;
This combined gas law is gotten from the combination of Charles' law, Boyle's law and the Pressure law.
At constant pressure(this means the pressure is unchanged or fixed and this means the pressure is eliminated), we have:
At constant volume(we eliminate the volume since it is fixed or unchanged), we have;
At constant temperature (we also eliminate temperature), we have
.
thus from the options provided in the question the right answer will be
