Answer:The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy
Explanation:
150 grams is .15 liters
1 mole of gas at STP occupies 22.414 liters
.15 liter of hydrogen represents .15/22.414 =
0.0066922 moles of H2
equation is
Zn + 2HCl → ZnCl2 + H2
1 mole of Zn will make 1 mole of H2
0.0066922 moles of Zn will make 0.0066922 moles of H2
To convert this molar quantity of zinc into grams we simply multiply by the atomic mass of zinc, which is
65.38 g/mol;-
Mass of Zn required = 0.0066922 moles * 65.38 g/mol = 0.4375390381 grams

Answer:
DNA is found in the cytoplasm of prokaryotes
Explanation:
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Your answer is A because the electron is removed and changed into a new proton which means that the atomic number is going up so does the element number.
