Volume of a rectangular block= 2.30x4.01x1.82=16.78cm3
Mass of the rectangular block= 25.71 g
Density of the block will be = 25.71/16.78=1.53 g/cm3
So the
ANSWER IS 1.53 g/cm3 density
<h2>Answer:</h2>
The correct answer is
A) Regular operation
<h2>
Explanation:</h2>
Even those workplaces that have established LO/TO processes face challenges, including: Lack of specific procedures written for each piece of equipment identifying all energy sources and energy isolation devices. Lack of comprehensive safety training for everyone in the workplace. Incorrect tag use.
So, regular operation is the primary cause of LO/TO accidents.
The most important thing to determine whether a change is physical or chemical is whether the substance was changed. When the substance being changed, it is chemical change. Otherwise, it is physical.
<span>London forces also known as "induced-dipole-induced-dipole interactions" and are in principle found in every molecule. The interaction occurs from the transient dipoles all molecules have as a result of fluctuations in the instantaneous positions of electrons.
</span><span>Dipole-dipole arises when we are able to set up a polarity in the molecule. So for an example if a highly electro-negative atom is bond to a less electro-negative atom then there will be a polarity in the molecule and we therefore have the dipole-dipole interaction.
</span><span>For the determination of geometry for the specific examples , use the VSEPR (Valence Shell Electron Pair Repulsion) model and by that determine the geometry.</span>
