Answer:
4180 Joules
Explanation:
Multiply 100g by the 10c to get the amount of degrees heating the amount of grams, which is 1000.
Specific heat is how much energy it takes to heat 1 gram 1 degree celcius, which it took 1000 of.
1000* specific heat for water = Total heat energy
1000*4.18J=4180 J
It took 4180 Joules of energy to heat up 100g of water by 10 C
Question: When an atom that has no charge loses two electrons, it becomes a:
A: positive ion.
B: negative ion.
C: positive isotope.
D: negative isotope.
Answer:
When an atom that has no change loses two electrons, it becomes "positive ion".
Explanation:
It is known that electrons hold a negative charge. So, when the negative charge that is electrons are taken out an atom then the number of electrons become less in number as compared to the number of protons. Hence, the atom attains a positive charge.An isotope is formed when an atom shows same number of protons and different number of neutrons. So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form.Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
