In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
Answer:
They were made in unstable conditions
Explanation: Im smarty pants
Explanation:
Group 1A +1
Group 3A +3 or +1
Group 5A +5 or +3
The charges on an ion signifies the number of electrons that has been lost, gained or shared by an atom. These electrons are called valence electrons occupying the outermost shell of an atom.
Group 1A element will readily be willing to lose an electron giving them a charge of +1
Group 3A can lose either 1 or 3 electrons giving a charge of +3 or +1
Group 5A can lose either 5 or 3 electrons giving a charge of +5 or +3
The number of lost electron confers the stability on the configuration.
