At 1.0 mol/min my teacher told me when I asked her yuh
Answer:
Strong acid.....(A)
Explanation:
hope this helps, the person above me is also correct
when the thermal energy is the energy contained within a system that is responsible for its temperature.
and when the thermal energy is can be determined by this formula:
q = M * C *ΔT
when q is the thermal energy
and M is the mass of water = 100 g
and C is the specific heat capacity of water = 4.18 joules/gram.°C
and T is the difference in Temperature = 50 °C
So by substitution:
∴ q = 100 g * 4.18 J/g.°C * 50
= 20900 J = 20.9 KJ
Answer:
The answer to your question is: C2 = 0.0004 M
Explanation:
Data
pH = 2.5; V = 1.0 L
V2 = 8.0 L C2 = ?
Formula
C1V1 = C2V2
C2 = C1V1 / V2
pH = -log[H⁺]
Process
[H⁺] = antilog -pH
[H⁺] = antilog (-2.5)
[H⁺] = 0.003 M = C1
Finally
(0.003)(1 l) = C2(8)
C2 = 0.003 / 8
C2 = 0.0004 M
