Answer:

The mass percent = 15.79 %

Explanation:

<u>Step 1:</u> Data mass

Mass KCl = 30 grams

volume of water = 160 mL

density of water = 1.00 g/mL

<u>Step 2:</u> Calculate mass of water

mass water = volume * density of water

mass water = 160 mL  / 1.00 g/mL

mass = 160 grams

<u>Step 3:</u> Calculate total mass of solution

30 grams + 160 grams = 190 grams

<u>Step 4:</u> Calculate mass % :mass KCl / Mass of solution

% mass = (30 grams / 190 gram) *100%

% mass = 15.79 %

The mass percent = 15.79 %

Which element would have a full outer shell of electrons if it gained three electrons?
Vsevolod [243]

Answer:

Octet Rule is defined as the chemical rule in which atoms tend to form bonds in such a way that it completes its valence shell or tend to achieve the configuration of a noble gas.

Explanation:

The lithium is chemical element, which has atomic number 3. It has one valence electron in its outermost shell, therefore, it will require 7 more electrons to complete its octet.

The element nitrogen has the atomic number 7, such that it has 5 valence electrons in its outer most shell. Therefore, it will require 3 more electrons to complete its octet.

The noble gas Argon have complete octet, such that it does not require any electrons to complete its octet. the gas is inert and non-reactive.

The chemical element Boron has atomic number 5, such that it has three electrons in its outer most shell. Therefore, it will require 5 more electrons to complete its octet.

Hence, the correct option is Nitrogen.

The normal boiling point of methanol is 64.7°c and the molar enthalpy of vaporization if 71.8 kj/mol. the value of δs when 2.1
kvasek [131]
The value or amount of heat that is needed in order to vaporize the given amount of methanol (CH3OH) can be calculated through the equation,
    H = (n)(hf)

where H is the amount of heat
n is the given amount in mol, and 
hf is the molar heat of vaporization

Substituting the known values,

  H = (2.15 mol CH3OH)(71.8 kJ/mol)
  H = 154.37 kJ

<em>ANSWER: 154.37 kJ</em>
