Answer:
Which scientist developed the first model of the atom that showed the structure of the inside of an atom
Ernest Rutherford
"The vapor pressure<span> of water is relatively </span>low<span> because it is held together through hydrogen bonds. This means that the molecules in a glass of water do not evaporate from the water very easily, as the molecules are attracted to each other."</span>
Answer:
The element that is commonly used to reduce iron oxide would be <u>carbon.</u>
Explanation:
:)
1. 0+15+30+45+60=150/5=30 s
0+10+16+22+27=75/5=15 cm^3
then, 15/30= 0.5 cm^3/s(average rate of rxn)
2. 0+15+30+45+60+75+90+105+120=540/9=60 s
0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3
then, 24.89/60=0.414cm^3/s (avrg rate of rxn)
3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn
4. 16/30= 0.533cm^3/s
5. 39.5/105= 0.37cm^3/s
We know that the molar mass of Al is 27 g/mol.
27 g Al* (1 mol Al/ 27 g Al)= 1 mol Al.
The final answer is 1 mol Al~
