<h2>Answer -
0.73%</h2>
14.6 .2
=
100 x
(Above is proportions I used to get the answer)
x = 0.73% which is the answer.
B. Rotten orange is the correct answer. Hope this helps!
Answer:
19 °C
Explanation:
Step 1: Given and required data
- Mass of granite (m): 20 g
- Heat absorbed (Q): 300. 2 J
- Specific heat capacity of granite (c): 0.790 J/g.°C
Step 2: Calculate the temperature change (ΔT)
We will use the following expression.
Q = c × m × ΔT
ΔT = Q/c × m
ΔT = 300.2 J/(0.790 J/g.°C) × 20 g = 19 °C
Answer:
A) HCl > HClO > HBrO > HIO
Explanation:
The strength of an acid is related to the acid dissociation constant (Ka). This is the equilibrium constant for an acid. The higher the Ka, the stronger the acid.
An easier way to compare the strength of acids is through their pKa, where
pKa = -log Ka
The lower the pKa, the stronger the acid.
Let's consider the following acids and their pKa values:
HCl -7
HClO 7.54
HBrO 8.62
HIO 10.64
The order of decreasing acid strength is:
A) HCl > HClO > HBrO > HIO
