Souring milk would actually be a chemical change because it changed the properties alltogether. You can't change soured milk into it's original taste.
The change in energy level is equivalent to the energy of the released photon. This is related by Planck's equation:
E = hcf
The higher the energy change, the greater the frequency, f, of the photon.
Hey there!:
moles of NaOH = 10.1 / 40 = 0.2525
heat = ΔH x moles
= 44.4 x 0.2525
= 11.21 kJ
total mass = 10.1 + 250 = 260.1 g
Q = m Cp dT
11211 = 260.1 x 4.18 x dT
dT = 10.3
T2 = 10.3 + 23 = 33.3 °C
temperature = 33.3 ºC°
Hope this helps!
Due to the presence of mobile or moving electrons in an atom they are good conductor of heat and electricity. Thus, the heat conduction and current conduction properties of metals are explained by its mobile electrons.
The other mentioned properties of metal are strength which can be explained by type of bonding within the metals, malleability explains the tendency of metals to be flattened into thin sheets, ductility explains the tendency to be stretched into wires, luster means the surface of metal is shiny and opacity is measure of impermeability that is to what extent they can pass light through them, metals are opaque, can not pass light through them or they are not transparent . All these properties are not because of mobile electrons in metals.
Therefore, correct properties are heat conduction and current conduction.
To convert from L to ml, we move three spaces to the right and the decimal place moves three places.
Our task here is to convert 600 L to mL. we have to remember that to convert from L to ml, we have to multiply the value in L by 1000
In other words, the value 1000 is known as the conversion factor.
When we do this, we move the decimal place three places to the right to have 600000.00mL
