Answer:
To determine the amount of heat the gold has absorbed to melt, we simply multiply the mass of the block of ice to the heat of fusion of water which is given above. We calculate as follows:
Heat = 20.0 g (35.4 g)
Heat = 1290 J
Ionic bond involves electrostatic attraction between oppositely charged ions.
The ions are atoms that have gained 1 or more electrons and atoms that have lost 1 or more electrons.
Answer: The type of bond that requires the give and take of electrons is
A ) ionic bond.
Answer:
![m=0.0158g](https://tex.z-dn.net/?f=m%3D0.0158g)
Explanation:
Hello there!
In this case, it is possible to comprehend these mass-particles problems by means of the concept of mole, molar mass and the Avogadro's number because one mole of any substance has 6.022x10²³ particles and have a mass equal to the molar mass.
In such a way, for C₆H₁₂O₆, whose molar mass is about 180.16 g/mol, the referred mass would be:
![m=5.28x10^{19}molecules*\frac{1mol}{6.022x10^{23}molecules}*\frac{180.16g}{1mol}\\\\m=0.0158g](https://tex.z-dn.net/?f=m%3D5.28x10%5E%7B19%7Dmolecules%2A%5Cfrac%7B1mol%7D%7B6.022x10%5E%7B23%7Dmolecules%7D%2A%5Cfrac%7B180.16g%7D%7B1mol%7D%5C%5C%5C%5Cm%3D0.0158g)
