Use you observation to determine which polymorph is in the customer’s returned chocolate sample.

1 answer:

7 0

Cocoa butter, the fat in chocolate, can crystallize in any one of 6 different forms (polymorphs, as they are called). Unfortunately, only one of these, the beta crystal (or Form V), hardens into the firm, shiny chocolate that cooks want. Form VI is also a stable hard crystal, but only small amounts of it form from the good beta (Form V) crystals upon lengthy standing. When you buy commercial chocolate it is in the form of beta crystals.

When you melt chocolate and get it above 94° F, you melt these much desired beta crystals and other types of crystals can set up. If you simply let melted chocolate cool, it will set up in a dull, soft, splotchy, disgusting-looking form. Even the taste is different. Fine chocolate has a snap when you break it and a totally different mouthfeel from the other cocoa butter forms.

hope it's help you......!!!!!!! 

please mark as brain list.......!!!!!!!

Matthew has been collecting quarters in a jar. He has 176 quarters. What is the value of the coins in his jar?

AURORKA [14]

Answer:

The correct answer is : 44 dollars.

Explanation:

A quarter is one fourth of a dollar that is the reason it is known as quarter. A quarter is 25 cents or 0.25 dollar in value. If Matthew has 176 quarters in his jar than the value of the total coins would be:

1 quarter = 0.25 dollar

1 quarter = 1/4 dollar.

4 quarter = 1 dollar

then, 176 / 4 = x dollar

= 44 dollar

Thus, The correct answer is : 44 dollars.

Suppose you needed a 0.0250 M sodium thiosulfate solution to conduct 6 titrations. Explain how you would make up this solution u

AysviL [449]

Explanation:

According to the law of dilution,

$M_{1}V_{1} = M_{2}V_{2}$

The given data is as follows.

$M_{1}$ = 0.4782, $V_{1}$ = ?

$M_{2}$ = 0.025 , $V_{2}$ = 250 mL

Hence, we will calculate the value of $V_{1}$ as follows.

$V_{1} = \frac{M_{2} \times V_{2}}{M_{1}}$

= $\frac{0.025 \times 250}{0.4782}$

= 13.07

Thus, we can conclude that we need 13.07 mL 0.4782 M sodium thiosulfate solution using pipette.

NaNO3 ———> **heat above the arrow**

yanalaym [24]

Answer:

D (Decomposition)

Explanation:

This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.
