Answer:
quantity of heat=mc*theta
=25*0.930(76-25)
=25*0.930*51
=1185.75J
=11.9kJ
Answer:
Molarity of HCl solution = 0.25 M
Explanation:
Given data:
Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)
Molarity of NaOH solution=M₁ = 0.185 M
Volume of HCl solution = V₂ = 0.0200 L
Molarity of HCl solution = M₂= ?
Solution:
M₁V₁ = M₂V₂
0.185 M ×0.025 L = M₂ × 0.0200 L
M₂ = 0.185 M ×0.025 L / 0.0200 L
M₂ = 0.005M.L /0.0200 L
M₂ = 0.25 M
Create and use more electricity then previously used before. A lot of power is created by burning fossil fuels, the burning of them will be increased so more is needed to give power to everyone.
Answer:
Throughout the explanations section below you will find a description of the question.
Explanation:
(1)
- Whether a solution would be positioned inside a separative funnel, combined water, as well as solvent, disintegrate particulate caffeine. In every stage, the caffeine content incorporated relies upon the coefficient of caffeine partitioning throughout the combination of water as well as fluid.
- Thus, increasingly caffeine is taken from the solvent whenever the moment you bring additional solvent. Consequently, we separate the solvent from the single component.
(2)
- For compounds to be mixed thoroughly and separated into different layers, a shuddering mixture within the dividing funnel would be essential.
- However, it vibrates the separation funnel forcefully, restricts airflow within the funnel, which can also induce the fluid under it to burst or causing fluid to fire.
Answer:
6.45 joules
Explanation:
energy=10×(55-50)×0.129
=1.29×5
=6.45 J
