They are both on animals (not humans). IDK, maybe?
Answer: It will be D which is number 4........
Neither type of light is likely to damage the material, because the material does not take in energy from either the X-ray light or the gamma ray light.
Explanation:
Answer:
12.044 X 10^23 molecules of NaOH
Explanation:
because NaOH is an ionic bond, we should be asking how many <em>formula units </em> are in 2 moles of NaOH, there are 0 molecules since NaOH is measured in formula units.
but for the sake of the problem I'll assume NaOH is measured in molecules
for every mol of something there are 6.022 X 10^23 of something of that something.
so there are 6.022 X 10^23 molecules for every mol of NaOH
that means we have 2 X 6.022 X 10^23 molecules in 2 moles of NaOH = 12.044 X 10^23 molecules of NaOH
Answer: E) does not exhibit covalent bonding since it's bonding between a metal and nonmetal.
Explanation:
<span>1) The charge of copper on the reactant side is 0 (it is solid copper thus not charged).
2) The charge of the copper ions on the product side is 2+ (when ionized it is evident that Copper in Copper Nitrate is in its 2+ form)
3) Copper was Oxidized since its oxidation state increased from 0 as a reactant to +2 as a product
4) The number of electrons transferred is 2 electrons. Since oxidation is the loss of electrons, then Copper lost 2 electrons.
