Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
Balanced equation:
Ca(OH)2+H2SO4=CaSO4+2 H20<span />
Conservation of energy
all of it should be transformed since the energy is convserved (neither destroyed nor created)
so answer is B
Answer:
The answer to your question is KNO₃ is soluble and Fe(OH)₃ is insoluble.
Explanation:
Data
Potassium hydroxide (KOH)
Iron nitrate Fe(NO₃)₃
Double displacement reaction
3KOH + Fe(NO₃)₃ ⇒ 3KNO₃ + Fe(OH)₃
Conclusion
KNO₃ is soluble because compounds containing alkali metals ions are
soluble and also compounds containing nitrate ion are soluble.
Fe(OH)₃ is insoluble because compounds containing OH are insoluble
except Ba(OH)₂
Answer:
Chlorine can be found in Period 3.
Explanation:
Periods on the periodic table are the rows (horizontal sections) that group elements together. By looking across Period 3, you will find Cl (chlorine).
