How much Naclo3 will dissolve at 50°C?

Iodine is blue-black, crystalline, and solid. It sublimes to a violet-colored gas and reacts with aluminum and many other metals

Pepsi [2]

Answer:

blue-black PHYSICAL PROPERTY
crystalline PHYSICAL PROPERTY
solid PHYSICAL PROPERTY
sublimes to a violet-colored gas PHYSICAL PROPERTY
reacts with aluminum and many other metals CHEMICAL PROPERTY

Explanation:

Chemical properties are visible through chemical reactions, in which the chemical identity changes to form new substances. On the other hand, physical properties are evident without a change in the identity of a substance.

Which of these five properties are physical and which are chemical?

blue-black PHYSICAL PROPERTY
crystalline PHYSICAL PROPERTY
solid PHYSICAL PROPERTY
sublimes to a violet-colored gas PHYSICAL PROPERTY
reacts with aluminum and many other metals CHEMICAL PROPERTY

How is aluminum used in a lithium ion type of battery?

r-ruslan [8.4K]

Answer:

Explanation:

Aluminium is used in rechargeable battery.

Aluminium ions provide the energy by flowing from anode to the cathode.

When the battery is recharged these ions comes to the anode.

The one ion gives three electrons. Which means one Al⁺³ is equal to the three Li⁺ ions. So, three unit of charge giving by ions increase the energy storage capacity.

The rechargeable batteries with aluminium gives low cost and low flammability.

It is safe to use because of inertness of aluminium and also easy to use in ambient environment.

Aluminium also have high volume capacity than lithium which means energy storage per volume is greater.

Its charge discharge cycles are also greater.

The aluminum ion batteries are also smaller in size.

A student neutralized 16.4 milliliters of HCl by adding 12.7 milliliters of 0.620 M KOH. What was the molarity of the HCl acid?

Katen [24]

V ( HCl ) = 16.4 mL / 1000 => 0.0164 L

M( HCl) = ?

V( KOH) = 12.7 mL / 1000 => 0.0127 L

M(KOH) = 0.620 M

Number of moles KOH:

n = M x V

n = 0.620 x 0.0127

n = 0.007874 moles of KOH

number of moles HCl :

HCl + KOH = H2O + KCl

1 mole HCl ------ 1 mole KOH
? mole HCl--------0.007874 moles KOH

moles HCl = 0.007874 * 1 / 1

= 0.007874 moles of HCl

M = n / V

M = 0.007874 / 0.0164

= 0.480 M
