Answer:
it is soluble in water
Explanation:

Convalent Bond energy is low
<span>Answer:
Once these values are put into the equation delta Q=mc delta T it will give you the same value for Q (change in energy) if the same fuel is used
50mL will mean it gets heated quicker making the experiment quicker
200mL would take longer to heat for the same change in temperature causing a longer experiment.</span>
A single sodium ion will combine due to its charge on it
Na^+
The single sodium ion has total one positive charge on it. so it requires only one electron or can bond to one negative charge
in the given polyatomic anions
a) CO3^-2 : it has two negative charge. So it will react with two sodium ions
it will forms Na2CO3
b) PO4^-3 :it has three negative charge. So it will react with three sodium ions
it will forms Na3PO4
c) SO4^-2 : it has two negative charge. So it will react with two sodium ions
it will forms Na2SO4
d) NO3^-1: it has one negative charge. So it will react with one sodium ion
it will forms NaNO3
Hence the correct answer is
Nitrate ion will react with single sodium ion as
Na+ + NO3- ---> NaNO3
Answer:
True.
Explanation:
Specific heat is the amount of heat required to raise one gram of a particular substance by one degree Celsius or Kelvin.
Formula for calculating specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
= m * Cp * delta T
