Ok the ML (the 3rd number) is not legit because the ML value can only be from -L to L (the second value)
Answer:
50. 5mol
Explanation:
The mass of Zinc required = 3.30 kg = 3300 grams
The relation between moles and mass is:
Atomic mass of Zinc = 65.38g/mol
The answer to three significant figures will be 50.5 mol
the system is in constant temperature
so it follows Boyle's law
i.e.P1V1=P2P2
where P1=initial pressure=788 tour
P2=final pressure= ?
V1=initial volume=235 ml
V2=final volume=0.115 ml
Answer:
Explanation:
Hello, in this case, one could consider the undergoing chemical reaction as:
Thus, since 1.0 g of strontium carbonate is placed, the equilibrium equation takes the following form, excluding the solid-stated species and considering just the carbon dioxide as it is gaseous:
Hence, since at the beginning there is no carbon dioxide, its pressure at equilibrium equals Kp:
Which was clearly defined above.
Best regards.
Answer:
Explanation:
This question appear incomplete. However, chemical substances that conduct electricity when dissolved in water are elctrovalent/ionic compounds. These compounds are usually made up of elements in group 1 and group 7 (for example NaCl, NaI and LiF) but could also be made up of group 2, group 3 and group 6 [for example Mg(OH)₂ and Al(OH)₃]. Thus, they can be loosely said to be found in those groups in the S and P blocks of the periodic table.
NOTE:
Sodium (Na) is found in group 1 (S-block)
Lithium (Li) is found in group 1 (S-block)
Chlorine (Cl) is found in group 7 (P-block)
Iodine (I) is found in group 7 (P-block)
Flourine (F) is found in group 7 (P-block)
Magnesium (Mg) is found in group 2 (S-block)
Aluminium (Al) is found in group 3 (S-block)
Oxygen (O) is found in group 6 (P-block)
Hydrogen (H) is found in group 1 (S-block)
