Answer:
Explanation:
Hello,
In this case, for dilution process, we can notice that the initial moles remain the same once the dilution is completed, therefore, both concentration and volume change considering:
In such a way for the given final volume, the resulting concentration is noticed to be:
This is supported by the fact that the higher the volume the lower the concentration.
Best regards.
Specific heat capacity= Quantity of heat/massxΔT
Shc of iron (constant)= 0.4494J/³C for 1g
1.49kg=1490g
Q=1490x(22-155)x0.4494
Q=<span>89057.598J</span>
The melting point will be the freezing point times .14
Answer:
Reduce the intensity of radiations
Explanation:
Atomic Emission Spectroscopy is the study of electromagnetic radiations that are emitted by matter when it is excited. It is used to analyze intensity of light emitted. To end the radiations of AFS and AES their intensity is reduced and they are gradually rejected. It is not possible to completely eliminate the radiations immediately.
