Answer:
<u>= 14.24g of </u>
<u> is required.</u>
Explanation:
Reaction equation:
→ 
Mole ratio of ammonium carbonate to carbon dioxide is 1:1
1 mole of CO2 - 44g
?? mole of CO2 - 6.52g
= 6.52/44 = 0.148 moles was produced from this experiment.
Therefore, if 1 mole of - 96.09 g
0.148 mol of -- ?? g
=0.148 × 96.09
<u>= 14.24g of </u><u> is required.</u>
Answer:
0.99mol/L
Explanation:
Molarity ( M) = # of moles of solute / volume of solution (L)
Volume of Solution = 100 mL or 0.1 L
Molarity ( M) = # of moles of solute / volume of solution (L)
Molarity (M) = 0.099 mol / 0.1 L = 0.99mol/ L
Hi there,
I hope you and your family are staying safe and healthy!
The correct answer is C
Each shell can contain only a fixed number of electrons. The first energy shell around a nucleus can hold up to 2 electrons. Then the second shell can hold up to 8 eletrcons.

Your answer is C. Both gasoline and litter would need to be physically separated from the water, because neither bonds with the water.
Answer:
The answer is in the picture.
Explanation:
The methanol molecule is on the top.
the three molecules are drawn in blue (the two water molecules and the methanol molecule), with the hydrogen bonds indicated with dashed lines. There are also oxygen lone pairs drawn as red dots, and the zones of negative density ( δ-, high concentration of electrons) and zones of positive density (δ+, low concentration of electrons) are marked.
