Answer:
I know that the electrons flow would be: The electrons will flow from lithium to zinc.
Explanation:
But I also dont know what would make this an even stronger battery.
Answer:
88,88 % de O y 11,11 % de H
Explanation:
La composición porcentual se define como la masa que hay de cada mol de átomo en 100g. Las moles de agua en 100g son:
<em>Masa molar agua:</em>
2H = 2*1g/mol = 2g/mol
1O = 1*16g/mol = 16g/mol
Masa molar = 2 + 16 = 18g/mol
100g H2O * (1mol / 18g) = 5.556 moles H2O.
Moles de hidrógeno:
5.556 moles H2O * (2mol H / 1mol H2O) = 11.11 moles H
Moles Oxígeno = Moles H2O = 5.556 moles
La masa de hidrógeno es:
11.11mol * (1g/mol) 11.11g H
La masa de oxígeno es:
5.556 mol * (16g / 1mol) = 88.89g O
Así, el porcentaje de O es 88.89% y el de H es 11.11%. La opción correcta es:
<h3>88,88 % de O y 11,11 % de H</h3>
Spores in the air or contamination through some sort of insect interaction. In an open system, there are billions of microbial agents floating around. With an open container containing a food source and time, the likelihood of contamination is nearly %100.
Answer:
Glass and lens making have improved, and electronic features for microscopes have become available
Explanation:
Answer:
The correct answer is KNO3
Explanation:
Pb(NO3)2 +2 KCl -> PbCl2 + KNO3
If we look at the left side of the equation we could see that there are 1 lead atom, 2 nitrate atoms ,2 potassium atoms and 2 chlorine atoms
Now when we look at the right side of the equation, we found that there are –
1 lead atom and 2 chlorine atoms (PbCl2) , thus lead and chlorine are balanced as they have the same number of atom in LHS and RHS
There is only 1 potassium and 1 nitrate atom on RHS , thus KNO3 is not balanced.
The balanced equation would be –
Pb(NO3)2 +2 KCl -> PbCl2 +2 KNO3
