You know, i always say no but when i watch one i get addicted so... yeah. thanks for the positive messages
Explanation:
Molarity=(initial molarityxinitial volume)/final volume
M=(3.5x25.4)/166.7=0.533 M
Answer:
iron is less reactive
Explanation:
therefore it will be extracted using carbon as it forms less stable oxides so little energy is needed to extract the metal.
Answer:
The molarity is 0,4M
Explanation:
The molartity is moles of compound (in this case KCl) in 1 liter of solution :
2 L----------0,8 moles KCl
1 L-----------x= (1L x0,8 moles KCl)/2L= 0,4 moles KCl--> 0,4M
