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

What is the density of a piece of metal with a
mass of 23.5 g and a volume of 11.1 mL? You
will report in units of g/mL. Please answer only
with a number. Include only two decimals in
your answer.
The density of the piece of metal is 2.12g/mL
HOW TO CALCULATE DENSITY:
Density, which refers to the mass of an object in relation to its volume, can be calculated by dividing mass by volume. That is;Density (g/mL) = mass (g) ÷ volume (mL)
According to this question, a piece of metal has a mass of 23.5 g and a volume of 11.1 mL, hence, the density can be calculated as follows:Density = 23.5/11.1
Density = 2.12g/mL

Hand tools in need of repair or replacement create hazards. Tools with wooden handles, like hammers and axes, can splinter or break in the middle of use, resulting in injury. Impact tools like chisels are unsafe for use if they have “mushroomed” heads because they could shatter on impact and cause injury.
Why are intensive properties useful for identifying a substance?
a
They are chemical properties.
b
They describe the amount of substance you have.
c
They are physical properties.
d
They do not depend on the amount of substance you have.
Answer:
d
They do not depend on the amount of substance you have.
Intensive properties useful for identifying a substance because they do not depend on the amount of substance you have.
WHAT ARE INTENSIVE PROPERTIES:
Intensive properties are physical properties of a substance that do not depend on the size or amount of a sample e.g. density, temperature, colour, boiling point etc. On the other hand, extensive properties are dependent on the size of a substance e. g. mass, volume, weight etc. Intensive properties of a substance do not change with respect to size, hence, they can be used in the identification of a substance.Learn more: https://brainly.com/question/3006850?referrer=searchResults

How do the respiratory system and circulatory system interact? (1 point)
o
In the lungs, carbon dioxide is transferred to the blood and carried by red blood cells. Once it is distributed, the red blood cells
pick up oxygen and transport it back to the lungs, where is transferred to the lungs so it can be exhaled.
O
In the lungs, oxygen is transferred to the blood and carried by red blood cells..Once it is distributed, the red blood cells pick up
carbon dioxide and transport it back to the lungs, where is transferred to the lungs so it can be exhaled
The respiratory system and circulatory system do not interact because the respiratory system is related to breathing and the
circulatory system is related to blood.
O
In the lungs, air is transferred into the blood stream, where red blood cells deliver it to the heart. The heart then separates the
oxygen and sends it to the organs, while sending the waste back to the lungs to exhale.
Explanation:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart

Which element would have the lowest electronegativity?
an element with a large number of valence electrons and a small atomic radius
an element with a large number of valence electrons and a large atomic radius
an element with a small number of valence electrons and a large atomic radius
an element with a small number of valence electrons and a small atomic radius
Answer:
an element with a large number of valence electrons and a large atomic radius
Explanation:
Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.
» If an atom has many valency electrons [ empty orbitals in outermost shell ], it has difficulty in attracting electrons hence electronegativity low.
» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.
[tex].[/tex]
The element that would have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.
Both electronegativity and atomic radius are periodic trends. Electronegativity increases across the period while atomic radius decreases across a period.
An element that has a small number of valence electrons and a large atomic radius will most likely be a metal hence it will have the lowest electronegativity.

Isotope ?-1 has an atomic mass of 1.
99.985% of all atoms of element ? are of this
form.
Isotope ?-2 has an atomic mass of 2
0.015% of all atoms of element ? are of this form.
Answer: Isotope-1: Hydrogen (H)
Isotope-2: Deuterium (H)
Explanation: The periodic table shows that the smallest element in hydrogen (H), at an average atomic weight of 1.008. Hydrogen-1 has one proton, one electron, and no neutrons, which adds to 1 AMU. Hyrogen-2 is an isotope of hydrogen that contains 1 neutron in addition to the proton, bringing the mass to 2 AMU. It is only at 0.0156% abundance on Earth and is given the name Deuterium, sometimes refered to as "heavy water" when incorporated into a water molecule. A third isotope has 2 neutrons, and is called Tritium.

Consider 81.0 g samples of two different compounds consisting of only carbon and oxygen. Compound 1 consists of 22.1 g of carbon, and compound 2 has 34.7 g of carbon. Determine the ratio in whole numbers of the masses of carbon that combine with 1.00 g of oxygen between the two compounds.
Answer:
Compound 1: CO2
Compound 2: CO
Explanation:
The attachment illustrrates the calculations. The masses of both C and O are converted into moles of those two elelements and the resulting mole values are taken as ratios of the two elements. Compound 1 has twice as many moles of O as of C, so it's empirical formula must be CO2. Compound 2's O/C ratio is 1, so it becomes CO.
