Hey there!
K₂Te + Fe(HCO₃)₂ → KHCO₃ + Fe + Te
Start by balancing HCO₃ since it's a polyatomic ion.
Two on the left, one on the right. Add a coefficient of 2 in front of KHCO₃.
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Balance K .
Two on the left, two on the right. Already balanced.
Balance Te.
One on the left, one on the right. Already balanced.
Balance Fe.
One on the left, one on the right. Already balanced.
Our final balanced equation:
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Hope this helps!
Answer:
- Britta paid more per kilometer driven
Explanation:
<u>1) Britta:</u>
- Distance traveled: 1,250 Km
- Gasoline price: 1.23 euros / liter
Cost per km = total cost of gasoline / distance traveled
Cost per km = gasoline used × gasoline price / distance traveled
Cost per km = 209 liter × 1.14 (euro / liter) / 1,250 km = 0.19 euro / km
<u>2) Pierce:</u>
- Distance traveled: 1,405 km
- Gasoline price = 1.23 euros / liter
Cost per km = 175 liter × 1.23 (euro / liter) / 1,405 km = 0.15 euro / km
<u>3) Comparison:</u>
- 0.19 > 0.15 ⇒ Britta paid more per kilometer driven
Answer:
It's B !
Explanation:
Formulas. The molecular formula for glucose is C6H12O6. This means that there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms bonded together to make one molecule of glucose.
