Explanation:

Intensive property: It is the property of substance which is independent of quantity of substance. Color of an ink is an intensive property.

Extensive property: It is the property of substance which depends upon quantity of substance which is just opposite to intensive property. Volume of an ink is an extensive property.

How many moles of calcium chloride are contained in a 333 gram sample?

Bogdan [553]

Answer & Explanation:

The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..

$\frac{333 g(CaCl2)}{} *\frac{1mol(CaCl2)}{110.98g(CaCl2)}$

Multiply straight across on the top and straight across on the bottom.

$\frac{333}{110.98}$

Now divide.

$\frac{333}{110.98}=3.00$

So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.

The p subshell can hold up to eight electrons in an atom (2 points) True or false?

hoa [83]

Answer: The statement is false

Explanation:

Electrons occupy a region in atoms known as orbitals or subs hell. These orbitals include

I) S-orbital: it can occupy a maximum of two electrons

II) P-orbital: It occupies a maximum of six electrons

III) D-orbital: it occupies a maximum of ten electrons

F and G-orbitals as examples of other orbitals present.

A good illustration of the 6 electrons occupied by the P-subshell is seen in Sodium (Na) with atomic number of 11

Na = 1s2, 2S2 2p6, 3s1

Note: extra electrons are transferred to the next orbital

What is the mass of 6.75 moles of CO₂?

ikadub [295]

Hi there!
Thank you for choosing Brainly.

1 mole = 44.0095

So take that number and multiply it by 6.75.

You then get... 297.0641

Have a nice day.

Calculate the [H3O'J in a solution that has a pH of 9.11. A) 7.8 x 10-10 B) 1.3 x 10-5 C) 9.1 x 10-9 D) 0.96 E) 0.69

puteri [66]

Answer: The correct answer is Option A.

Explanation:

pH is defined as negative logarithm of hydronium ion concentration. It is basically defined as the power of hydrogen ions that are present in a solution.

Mathematically,

$pH=-\log[H_3O^+]$

pH of the solution = 9.11

Putting values in above equation, we get:

$9.11=-\log[H_3O^+]$

$[H_3O^+]=antilog(-9.11)$

$[H_3O^+]=7.8\times 10^{-10}$

Hence, the correct answer is Option A.
