Answer:
NiO Does Not Dissolve In An Aqueous Solution Of NaNO3.
Explanation:
Answer:
Number of candies
Explanation:
The independent variable in this experiment is the number of candies eaten by the student.
An independent variable is best pictured as the cause in an experiment. It is the reason why the effects in experiments are produced.
In this experiment, the hyperactivity is the hyperactivity is the dependent variable. It is the effect that is produced in this set up.
A
single oxygen has atomic number 8 that means the nuclei of all oxygen atoms
have eight protons. The number of minus-charged electron is two but the number
of electrons is 10. <span>To gain a minus two-charge ion, it
must have two more negative electrons than positive charged protons. With this,
the ion has 10 electrons, which give it a -2 net charge. </span>
<span>The key in
the balancing of chemical reaction is to make sure that you got the exact
chemical formula of the substance that is reacting and the yielded product.
After getting the formula, identify first the hardest element/atom to be
balanced such as Na, Zn, Cl, C, O, etc. Then proceed to the easier ones such as
O, H. Make sure to note the atoms present in the molecule of the substance. Among
the three equations, PCl2 + 4H2O --->H3PO4 + 5HCL is not balanced. The
hardest element here is the Cl. Observe that there are 5Cls in the product side
so you must add 5 to the PCl2. However, there are only 2Cl atoms and it needs
3 to balance the equation. Also, there is no P in the product side. This equation
is invalid.</span>
The type of chemical reaction that the reactants will undergo would be a single displacement reaction.
In a single displacement reaction, one element gets substituted or replaced by another element in a compound. This often leads to the formation of a new compound (aqueous) and a new element (solid or precipitate).
Thus, the complete equation of the reaction becomes:
Cu displaced Ag from AgNO3. Thus Ag becomes precipitated in solution while a new compound, CU(NO3)2 is formed.
