Answer:
1) No, 2) Yes, 3) Yes
Explanation:
Refer to solubility rules to understand if a precipitate occurs between a mix of solutions.
The answer is false. It is because the electron structure of
the atom is not determined by using the direct observation of using an x-ray
but rather the usage of theoretical modeling and the emission spectra will be useful
in observing.
The law of conservation of mass is must be applied when cooking.
<h3>What is conservation of mass?</h3>
Law of conservation of mass states that mass of any substance will change into another form without any loss of mass, means destroying of mass is impossible.
When we cook food then mass of conservation is applied there, for example we are boiling pulses with water then in that case the amount of formed liquid pulses is equal to the initial mass of solid pulse with water.
Hence law of conservation of mass is applicable during cooking.
