It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world
Ans: 15.1 grams
Given reaction:
Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3
Mass of Na2CO3 = 20.0 g
Molar mass of Na2CO3 = 105.985 g/mol
# moles of Na2CO3 = 20/105.985 = 0.1887 moles
Based on the reaction stoichiometry: 1 mole of Na2CO3 produces 2 moles of NaOH
# moles of NaOH produced = 0.1887*2 = 0.3774 moles
Molar mass of NaOH = 22.989 + 15.999 + 1.008 = 39.996 g/mol
Mass of NaOH produced = 0.3774*39.996 = 15.09 grams
I believe your answer would be friction...
Answer:
Frying a hamburger
Explanation:
when frying a hamburger you change the properties of the meat by applying heat and in the other answer choices the element is not changed.
0.0931
9.31 x 10^3 is 9310
So 0.0931 x 10^5 equals to 9310.
When the raised power increases shift the decimal to the left hand side. If the raised power decreases then shift it to the right hand side.
Hope this helps
