The accuracy of an indicator’s end point depends on the relative strength of the metal–indicator complex and the metal.<span>Unfortunately, because the indicator is a weak acid, the color of the uncomplexed indicator also changes with pH.</span>
Here's a chart that will help you color in the periodic table for #20:
The specific heat of unknown material : 3.675 J/g °C
<h3>Further explanation</h3>
Given
mass of block = 22.5 g
Q = heat = 2067 J
Δt=25 °C
Required
The specific heat
Solution
Heat can be formulated :
Q = m.c.Δt
Input the value :
2067 J = 22.5 g x c x 25 °C
c = 3.675 J/g °C
Answer:
Compound C is covalent.
Explanation:
Among the properties of a covalent compound is that it has poor conductivity and could possibly be a gas at room temperature.
A : it can be proven by philosophy and religion
