Answer:
B
Explanation:
Atomic # = Protons
it says 4 p in the inside of the orbital
Answer:
.
Explanation:
Electrons are conserved in a chemical equation.
The superscript of indicates that each of these ions carries a charge of . That corresponds to the shortage of one electron for each ion.
Similarly, the superscript on each ion indicates a shortage of three electrons per such ion.
Assume that the coefficient of (among the reactants) is , and that the coefficient of (among the reactants) is .
.
There would thus be silver () atoms and aluminum () atoms on either side of the equation. Hence, the coefficient for and would be and , respectively.
.
The ions on the left-hand side of the equation would correspond to the shortage of electrons. On the other hand, the ions on the right-hand side of this equation would correspond to the shortage of electrons.
Just like atoms, electrons are also conserved in a chemical reaction. Therefore, if the left-hand side has a shortage of electrons, the right-hand side should also be electrons short of being neutral. On the other hand, it is already shown that the right-hand side would have a shortage of electrons. These two expressions should have the same value. Therefore, .
The smallest integer and that could satisfy this relation are and . The equation becomes:
.
Answer:
The answer to your question is Ferns
Explanation:
Ferns are called nonflowering plants and produce spores instead of seeds.
At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L
This rule is applied to O₂
22.4 L volume occupied by 1 mol
Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol
stoichiometry of O₂ to H₂O is 1:2
then the number of moles of water produced - 3.72 mol x 2= 7.44 mol
mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g
correct answer is D
Answer:
The microbiome is defined as the collective genomes of the microbes (composed of bacteria, bacteriophage, fungi, protozoa and viruses) that live inside and on the human body. We have about 10 times as many microbial cells as human cells.
