Answer:
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom.
When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
what does radiation do?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom
What is the molarity of a solution that contains 80.0 grams of NaOH dissolved in 500 mL of solution? Student prepares a solution by dissolving 3.72 g of NaOH in enough water to make 300.
Answer:
Synthesis Reaction
Explanation:
Here we see H2 and O2 are being combined H2O. Synthesis reactions are where we see a combination to make a <u>single product</u>.
So here it'd be A + B =AB
2Na(s)+Cl2(g)→2NaCl(s)
Decomposition would be the break down of a compound into 2, the opposite of synthesis.
AB = A + B
2HgO(s)→2Hg(l)+O2(g)
Single replacement is where 1 element replaces another in a reaction, or switches place with 1 element.
AY + B = A + BY
2 HCl(aq) + Zn(s) → ZnCl2(aq) + H2(g)
Double replacement is similar but 2 elements are switch/replaced.
AY + BX = AX + BY
CuCl2(aq) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 AgCl(s)
The answer should be 0.78
