Answer:
B
Explanation
Salt water is a solution where the salt completely dissolves therefore is is homogeneous. Solvent is the liquid (water) that dissolves the solute (salt).
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:
Number of moles = 0.35 mol
Explanation:
Given data:
Mass of H₂SO₄ = 34.6 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of H₂SO₄ = 98.1 g/mol
by putting values,
Number of moles = 34.6 g/ 98.1 g/mol
Number of moles = 0.35 mol
Answer:
carbon
Explanation:
Carbon forms compounds that make up about 18 percent of all the matter in living things. The processes by which organisms consume carbon and return it to their surroundings constitute the carbon cycle.
