Answer:
the energy of the products is less than the energy of the reactants.
Explanation:
the the change is enthalpy is negative, and heat is released to the surroundings.
Answer:
Mitosis
Explanation:
A cell that contains the same DNA as its parent cell is a product of mitosis.
- Mitosis is a cell division process that takes place in somatic cells.
- In meiosis a single cell divides to produce two daughter cells each having the same DNA as the parent
- Mitosis ensures that the same DNA is found between the parent
- Mitosis is used for repairing and production of new cells.
6.4*10^10 is the answer in scientific notation
Answer:
I'm pretty sure that it gains 2 electrons
Answer:
If it loses 2 electrons, the net charge on the atom will be 2+
If the atom instead gains 4 electrons, the net charge will be 4-
Explanation:
It is based on adding and subtracting charges. Protons are +1 and electrons are -1
If the atom has 9 protons and 9 electrons, the net charge is +9 + (-9) = 0. The +9 is the 9 protons and the -9 is from the 9 electrons.
If two electrons are taken away, there would be 9-2 or 7 electrons with 9 protons. The net charge would then be +9 + (-7) = +2. +9 comes from the 9 electrons and -7 is from the 7 electrons.
So, if two electrons are taken away, the net charge is +2.
Similarly, if the atom gains 4 electrons, there will be 9+4 or 12 electrons and 9 protons. The net charge would then be +9 + (-12) = -4. +9 comes from the 9 protons and -12 comes from the 12 electrons.
So, if 4 electrons are added, the net charge is -4.
