No it does not ALWAYS go through all the stages because each rock forms differently at different rates. Igneous rock can weather to sediement rock, or melt to magma, however this does not necessarily mean it does this every time. It all depends on the temperature, wind, and pressure/heat.
Compounds are not formed by accepting electrons. Number 1 and 3 are correct.
Answer:
mass Na2SO4 = 14.3816 g
Explanation:
sln Na2SO4:
∴ V = 450 mL
∴ <em>C </em>=<em> </em>0.2250 mol/L
∴ Mw ≡ 142.04 g/mol..... from literature
⇒ mol Na2SO4 = (0.2250 mol/L)(0.450 L) = 0.10125 mol
⇒ mass Na2SO4 = (0.10125 mol)(142.04 g/mol) = 14.3816 g
Yes, you can use up all the resources in the world if the human race inst careful.
The nucleus is the positively charged core of an atom, which is surrounded by a cloud of negatively charged electrons. Nucleons are particles that the core of an atom consists of, namely positively charged protons and neutral neutrons. That is, thenucleus is made up of nucleons.
