The average speed :
1. 10.44 m/s
2. 10.42 m/s
3. 9.26 m/s
The distance 100 m have the greatest average speed
<h3>Further explanation
</h3>
Given
Distance and time of runner
Required
Average speed
Solution
<em>
Average speed : total distance : total time
</em>
1. d = 100 m, t = 9.58 s
Average speed : 100 : 9.58 = 10.44 m/s
2. d=200 m, t=19.19 s
Average speed : 200 : 19.19 = 10.42 m/s
3. d=400 m, t = 43.18 s
Average speed : 400 : 43.18 = 9.26 m/s
The distance 100 m have the greatest average speed
12cm cubed.
Formula is length x width x height and in this case it would be 2x3x2 which equals 23
Answer:
Conjugate base: Propionate
Explanation:
- Conjugate base contains one less proton as compared to it's parent acid. Deprotonation occurs from most acidic region.
- Propionic acid deprotonates to produce it's strong conjugate base propionate.
- In propionic acid, -OH group in -COOH functional moiety dissociates to produce
. Because the O-H bond electrons remains highly polarized towards oxygen atom due to electron withdrawing inductive effect as well as resonating effect of -COOH moiety.
- Structure of conjugate base has been shown below.
Answer:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
Explanation:
Reactants;
Calcium hydroxide = Ca(OH)₂
Hydrogen chloride = HCl
Products;
Calcium chloride = CaCl₂
Water = H₂O
The reaction equation:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.
