Answer:
D
Explanation:
Someone's perception can be all of these things. the way one person sees something is different than the way someone standing right beside them sees it.
NaOH is a strong base so pH will be around 13 to 12. Whatever number of moles of NaOH you have approximately the pH of NaOH will be around 14 13 or 12
<span>A substance is composed entirely of one type of atom, it is known as a Chemical element
because mixture contain more than one type of atom and it cannot be neutron or isotope
so correct option is B
hope it helps</span>
Answer:
1 kiloliter = 1,000,000 milliliters
45 × 1,000,000
45 KL = 45,000,000 ML
Answer:
Molecules are moving faster in the glass of Steam.
Explanation:
The three physical states of H₂O are Ice (Solid state), Water (Liquid state) and Steam (Gas state) respectively.
As we know the particles (i.e. molecules) in solid state are stationary and they are unable to change their position and are only vibrating therefore we can omit the option of Ice.
When heat is provided to Ice it melts into liquid water. The molecules are still interacting via intermolecular forces. In this state the molecules are not stationary. They exist in the form of layers (due to intermolecular forces) and these layers slide over each other hence, resulting in the change of position of molecules.
While, when liquid water is further heated it converts into steam ( a gas sate). In this state the molecules are not interacting with each other. They move faster in random directions and collide with each other. Hence, this is the correct answer.
