The statement about the battery which is correct is; a new substance is formed as the battery is used.
Lithium ion batteries have become part of most modern devices such as cell phone, laptop computers and other digital devices.
It shorter time of recharge and good battery life has continued to make it a top choice in the electronics industry.
The equation that describes the chemistry of lithium ion battery is;
LiC6 + CoO2 ⇄ C6 + LiCoO2
The reaction goes towards right hand side when the battery is in use and towards the left hand side when that battery is recharging.
Hence, from the equation, we can see that a new substance, LiCoO2 is formed when the battery is in use.

<span>The importance of discovering gravitational
waves are; one, we can measure the activity between two bodies in orbit in the
universe, two, scientist can estimate the merging of two bodies in the universe
every 15 minutes by using LIGO and three, we can know the behavior of other
bodies that we did not know exist.</span>
Answer:
The 2 light bulbs can be connected in parallel to each other to avoid disconnection when one bulb burns out.
Explanation:
The parallel connection is required not series. A parallel connection is the connection of electronic components (e.g bulbs, LED, resistors, capacitors etc) in such a way that the same voltage is supplied across the ends of the components. While in a series connection, the components are connected to each other end-to-end.
As regard the question, parallel connection ensures that the brightness any of the bulbs is not affected with respect to the other bulbs. And other bulbs continue to function when any burns out. The 2 light bulbs should be connected in parallel to the baterry to avoid disconnection of all the bulbs.
volume of milk is given as
we will convert it into mL unit
mass of the milk m = 2kg
m = 2000 g
now for the density we can use
<em>so the density is 0.264 g/mL for above sample</em>
