Answer: yes they come in different colors.
Explanation:
Most shades of soil is mostly black,brown,red,gray,and white the color of soil and other properties including texture, structure, and consistency are used to distinguish and identify soil.
Answer:
4.4 g
Explanation:
The equation of the reaction is;
NaHCO3 (aq) + CH3COOH (aq) ----> CO2 (g) + H2O (l) + CH3COONa (aq)
Mass of baking soda - 4.5 g
Molar mass of NaHCO3 = 84.007 g/mol
Number of moles of baking soda= 4.5 g/84.007 g/mol = 0.0536 moles
If 1 mole of NaHCO3 yields 1 mole of CH3COONa
0.0536 moles of NaHCO3 also yields 0.0536 moles moles of CH3COONa
Hence;
Theoretical yield of CH3COONa = 0.0536 moles * 82.0343 g/mol = 4.4 g
<h3>
Answer:</h3>
5.89%
<h3>
Explanation:</h3>
We are given;
- Mass of the solute, LiOH as 40.1 g
- Mass of the solvent, H₂O as 681 g
We are required to calculate the mass percent composition of solution;
- But; How do we calculate the mass percent composition of a solution?
- We use the formula;
- Mass composition of a solution = (Mass of solute/mass of solution) 100%
Mass Percent = (40.1 g/681 g)× 100%
= 5.888 %
= 5.89%
Therefore, the mass percent composition of the solution is 5.89%
