Answer:
im pretty sure the electron configuration of the barium ion Ba+2 is [Kr]5s24d105p6
Explanation:
Answer:
2100g or 2.1kg
Explanation:
Based on the equation given,
One mole of Fe2O3 gives two moles of Fe
Molar mass for Fe2O3 is 160g/mol
Molar mass for two Fe is 112g/mol
Convert 3kg to gram
3×1000=3000grams
160g of Fe2O3-112 g of Fe
3000g of Fe2O3-xg of Fe
Xg=3000×112/160
Xg=2100g
To convert to kg
2100/1000=2.1kg
Mass of Fe is 2.1kg
A possible cause of a large percentage of error in an
experiment where MgO is produced from the combustion of magnesium would be not all of the Mg has
completely reacted. <span>

No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.
Answer:

Explanation:
Hello!
In this case, since the molarity is defined as moles of solute divided by liters of solution, since we have phenol with a molar mass of 94.12 g/mol, we can first compute the moles in 1.5 g of phenol:

Next, since 1000 mL = 1 L, we notice that the volume of the solution is 0.100 L and therefore, the molarity of such solution turns out:
