Hopefully this is correct and I believe CO2 is bad because the cells in the body need oxygen to then release energy from food efficiently by carrying out aerobic respiration. And a waste product of aerobic respiration is Carbon Dioxide. And Carbon dioxide must be removed from our bodies or it them makes the blood dangerously acidic.
Hope this helps :)
Answer:
Option D
Explanation:
A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
A common means of expressing quantities, the values of which may span many orders of magnitude, is to use a logarithmic scale.
The hydroxide ion molarity may be expressed as a p-function, or pOH.
pOH = −log[OH−]
Basic solutions are those with hydronium ion molarities less than 1.0 × 10−7 M and hydroxide ion molarities greater than 1.0 × 10−7 M (corresponding to pH values greater than 7.00 and pOH values less than 7.00).
Most young children already have plenty of energy without the need for coffee to sustain them throughout the day, so at least until they are 12 years old, it's best to avoid giving your kids coffee if possible
The balanced chemical reaction is written as:
<span>2Al2O3 = 4Al + 3O2
We are given the amount of aluminum oxide used in the reaction. This will be the starting point for the calculations. We do as follows:
26.5 mol Al2O3 ( 3 mol O2 / 2 mol Al2O3 ) = 39.75 mol O2 produced</span>
Answer:
Explanation:
1 . periodicity
repeating nature of atomic structure
Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.
2 . shell
location of an electron
Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high
3 . non-metals
high ionization energies
Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.
4 . noble gases
least reactive family
Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.
5 . neutral
charge on a neutron
Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons
6 . repel
like charges
Like charges repel one another
7 . attract
unlike charges
Unlike charges attracts. Positve attracts negative charges.
