Answer:
copper
Explanation:
These are usually copper wires with no insulation. They make the path through which the electricity flows. One piece of the wire connects the current from the power source (cell) to the load
Answer:
30
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.
This further means that the amount of matter in the reactant of a reaction must equate that of the products.
Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.
Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
Answer:
30 g. 8'C
Explanation:
the 10 g is plus the fact that I have to help you get the chance to get the answer
To solve for the concentration of nitric acid in mol/L or also M. We use the equation,
M₁V₁ = M₂V₂
Where M stands for the molarity and V is for volume. Substituting the known values,
(0.10 M)(13.0 mL) = (M₂)(17 mL)
M₂ = 0.076 M
Thus, the concentration of the nitric acid is approximately 0.076 M.
Answer:
carbon and silicon
Explanation:
Various groups of elements in the periodic table have different outermost shell electron configurations. Actually, elements are classified into groups on the basis of the number of electrons on the outermost shell of those elements. All elements with the same number of electrons on their outermost shell belong to the same group in the periodic table.
For elements in group 14, they all have four electrons on their outermost shell. Their general outer electron configuration is ns2 np2 as shown in the question. Two prominent members of this group are carbon and silicon. This ns2 np2 is the ground state outer electron configuration of all group 14 elements in the periodic table.
