Non radioactive carbon 13 has 7 protons per atom.
The answer is: " NaCl + H₂O " ; (or; write as: " H₂O + NaCl " ) .

This type of "double-replacement" reaction is called "neutralization".
Since we are adding a strong acid to a strong base (reactants), we know that the product will be: 1) a salt ; and 2) water. Since we know one of the reactants will be "water" (H₂O) ; we can find the base (i.e. , the "remaining product") from selecting the "unused elements" to form the corresponding "salt".

Answer:
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.
Explanation:
Hello there!
In this case, according to the given reactions, it is possible to realize that according to the reactivity series, since K is is group 1A of alkali metals, we infer it is by far more reactive than magnesium, for that reason last two choices can be easily discarded. Now, considering equation 2, it would be necessary to complete it to figure out the correct option:
Whereas it can be seen that potassium exchanges position with Pb according to the double displacement reaction; therefore, the correct answer is "Equation 2, because K being more reactive, exchanges position with Pb in PbNO3".
Best regards!
Answer:
it depends on the mass of the object but sometimes smaller objects have more density the higher the mass the the lower the density
Since the two differ in molecular structure, their
recognition profiles for the two substances are very different. Substance
identification is a procedure by which the distinctiveness of the substance is recognized.
Octanoic acid is the eight-carbon straight chain fatty acid while octanol
is a fatty alcohol.
