Heat flow by conduction requires that the two systems must not be touching each another.
<h3>What is heat energy?</h3>
Heat energy is a form of energy that exists due to a temperature difference between two objects.
Heat energy flows from an object at higher temperature to an object at a lower temperature.
Heat transfer by conduction involves the vibration of particles of the medium transferring heat due to contact between the two objects.
Therefore, heat flow by conduction requires that the two systems must not be touching each another.

So if they fall, the padding will protect their neck or body part so they will not hit hard against the hard wooden or tile floor.
The dichloromethane (DCM) has less density than water and also the polarity of water is much more than DCM. So the mixture of water and dichloromethane will always be a heterogeneous mixture. In the mixture dichloromethane will be always up of the water layer. The volume of the separatory funnel which contains the mixture of DCM and water must have to be more than the total volume of the liquids thus the volume of the funnel will be more than (50+50) = 100mL.
The caution have to consider during the separation are-
1. The separatory funnel have to shake well with lid and have to settle down for some times until the two liquid separated.
2. The lid should be open very slowly as the vapor pressure of DCM is more and it will float on the water.
3. After this the stopcock should be opened and slowly the water will come out first followed by DCM.
The metal ion in an ionic compound will loose an electron becoming a cation. It will therefore develop a positive charge. The magnitude of the charge depends on the number of electrons lost. If one electron is lost the ion gains a +1 charge and of 2 is lost it gains a +2 charge ect.
Answer: the answer is b: sp3d
Explanation: BrF3 has a Bent T shaped structure with Br as a central atom bonded with three F atoms (three bond pairs) and two lone pairs. Hence , the hybridization would be sp3d. Br atom has 7 electron in its outer most shell. After the bond formation of BrF3 molecule we have 3 bond pairs+ 2 lone pairs
