soap and water would be the best soak it in water for 20 miuntes then wash it
Answer:
527.74 mL of oxygen gas should be produced under conditions of STP from a 1.52 grams sample of iron (III) perchlorate .
Explanation:
Volume of the oxygen gas under given conditions 
Pressure of the oxygen gas , 
(1 atm = 760 Torr)
Temperature of the gas of the oxygen gas ,
At STP. the pressure of the gas = 
At STP, the temperature of the gas= 
At STP. the volume of the oxygen gas = 
Using combined gas law to find out the volume of oxygen gas at STP:
527.74 mL of oxygen gas should be produced under conditions of STP from a 1.52 grams sample of iron (III) perchlorate .
Answer:
23.4 mph
Explanation:
The conversion factors are multiplied so that the units cancel out:
(100 meters / 9.58 sec) x (1 mile / 1609 meters) x (60 sec / min) x (60 min /1 hr) = 23.4 mph
5f− inner transition series of elements are placed separately at the bottom of the periodic table. Reason: (i) This prevents the undue expansion of the periodic table i.e., maintains its structure. (ii) This preserves the principle of classification by keeping elements with similar properties in a single column.
<h3>What is the difference between transition and inner transition elements?</h3>
The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.
<h3>How many inner transition elements are there?</h3>
Total number of inner transition elements in periodic table is 28, 14 each in lanthanoid and actinioid series.
