Answer:
As mass increases the gravitational force increases
Explanation:
Things with mass gain a gravitational force, The bigger they are the more force, for example: the sun is the biggest so it pull us
Answer:
Rb<K<Ga<As<Se<S
Explanation:
We must remember that first ionization energy decreases down the group and increases across the period.
First ionization energy decreases down the group because of the addition of more shells which increases the distance between the nucleus and the outermost electron. Hence, Rb has a lower ionization energy that K.
Across the period, increase in the size of the nuclear charge causes the pull of the nucleus on the outermost electrons to increase thereby increasing the ionization energy. Hence ionization energy increases across the period. For this reason, the ionization energy of Ga<As<Se as shown.
Answer:
This is the answer
Explanation:
charges passed = current x time = 10 x 3 x 60
= 1800 C
mole of charge = 1800 / 96500
= .01865 moles
Au+3 contains 3 positive charges
3 mole of charge will deposit 1 mole of Au .01865 moles will deposit .01865 / 3 mole
= 6.2167 x 10-3 moles.
Answer: 
Explanation:
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
The complete ionic equation is;
The ions which are present on both the sides of the equation are 
and 
and are not involved in net ionic equation.
Hence, the net ionic equation is :
