Answer:
True
Explanation:
Becuse the humans are dipositing billions of plastic and it has just grown over the years.
(1) a beta particle is your answer. Na-24 decays through beta decay, turning a neutron into a proton, electron (beta particle), and an neutrino.
Answer : The electron configurations consistent with this fact is, (b) [Kr] 4d¹⁰
Explanation :
Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom are determined by the electronic configuration.
Paramagnetic compounds : They have unpaired electrons.
Diamagnetic compounds : They have no unpaired electrons that means all are paired.
The given electron configurations of Palladium are:
(a) [Kr] 5s²4d⁸
In this, there are 2 electrons in 's' orbital and 8 electrons in 'd' orbital. From the partial orbital diagrams we conclude that 's' orbital are paired but 'd' orbital are not paired. So, this configuration shows paramagnetic.
(b) [Kr] 4d¹⁰
In this, there are 10 electrons in 'd' orbital. From the partial orbital diagrams we conclude that electrons in 'd' orbital are paired. So, this configuration shows diamagnetic.
(c) [Kr] 5s¹4d⁹
In this, there are 1 electron in 's' orbital and 9 electrons in 'd' orbital. From the partial orbital diagrams we conclude that 's' orbital and 'd' orbital are not paired. So, this configuration shows paramagnetic.
Answer:
let's do no.3
Na2O+H2SO4 > Na2SO4 +H2O
Al2O3+3H2SO4>Al2(SO4)3+3H2O
the three before the sulphuric acid is such that the equation balances on both ends

When paper burns, it releases two distinct forms of energy
Thermal Energy
Light Energy
Thermal Energy is heat energy, heat energy is formed from the flame on the paper, in this scenario.
Light energy comes from the reaction of the paper, the flame.
In conclusion, both energy's form from the reaction of the paper, and the combustion in the air. Thus, heat and light.
