Mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a portion salad, trail mix, and concrete (not cement).
Answer:
I think that this would be an example of erosion
Answer:
1.54grams
Explanation:
Molarity of a solution = n/V
Where;
n = number of moles (mol)
V = volume (L)
Based on the information given in this question;
Volume of NaOH solution = 5.0 × 10ml
= 50ml = 50/1000 = 0.050 L
Molarity = 0. 77 M
Using; Molarity = n/V
0.77 = n/0.05
n = 0.77 × 0.05
n = 0.0385mol
To find the mass (grams) of NaOH in the solution, we use the following formula:
mole (n) = mass/molar mass
Molar mass of NaOH = 23 + 1 + 16 = 40g/mol
0.0385 = mass/40
mass = 0.0385 × 40
mass = 1.54grams.
The answer is Q because the red it's absorbed by object Q meaning only black will show
Answer:
0.013 M/s
Explanation:
Given data
- Initial concentration of BrO⁻: 0.56 M
- Final concentration of BrO⁻: 0.14 M
Since the final concentration of BrO⁻ is lower than the initial concentration of BrO⁻, BrO⁻ is dissapearing. The rate of dissapearance of BrO⁻ is:
rBrO⁻ = - Δ [BrO⁻] / t
rBrO⁻ = - (0.14 M - 0.56 M)/ 33 s
rBrO⁻ = 0.013 M/s
