Answer:

A

Explanation:

Each 12 oz of latte contains 8 oz of milk, as the group of people ordered 12 lattles we need

12 x 8 = 96 oz of milk

As 33.8 oz is a litre

33.8 oz - 1 L

96 oz - x

x = \frac{96}{33.8} = 2.84 L

As Brandon have 2.5 L of milk

2.84 L - 2.5 L = 0.34 L

He will be short 0.34 L

How can you recognize an alcohol?
gavmur [86]

Answer:

O D. It has an -OH group attached to the end of the molecule.

Explanation:

Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule

{ \rm{R - OH \:  : \: primary \: alcohol   \: (1 \degree)}}  \\  \\ { \rm{R -(OH) - R {}^{i}  \:  : secondary \: alcohol \: (2 \degree)}} \\  \\ { \rm{R - R {}^{i} (OH) - R {}^{ii}  \:  : tertiary \: alcohol \: (3 \degree)}}

  • R is aryl or alkyl group
  • OH is hydroxyl group

Sodium sulfate dissolves as follows: Na2SO4(s) → 2Na+(aq) + SO42- (aq). How many moles of Na2SO4 are required to make 1.0 L of s
maxonik [38]

<u>Answer:</u> The number of moles of Na_2SO_4 is 0.05 moles.

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

We are given:

Molarity of solution = 0.10 mol/L

Volume of solution = 1 L

Putting values in above equation, we get:

0.10mol/L=\frac{\text{Moles of sodium}}{1.0L}\\\\\text{Moles of sodium}=0.10mol

The chemical reaction for the ionization of sodium sulfate follows the equation:

Na_2SO_4(s)\rightarrow 2Na^+(aq.)+SO_4^{2-}(aq.)

By Stoichiometry of the reaction:

2 moles of sodium ions are produced by 1 mole of sodium sulfate

So, 0.10 moles of sodium ions will be produced by = \frac{1}{2}\times 0.1=0.05moles of sodium sulfate.

Hence, the number of moles of Na_2SO_4 is 0.05 moles.
