when you hard boil an egg, the hydrogen sulfide produced by heating the egg white can react with iron from the egg yolk to form a grayish-green ring around the yolk.
In order to make a peanut butter and jelly sandwich you need two slices of bread 12 g of peanut butter and 15 g of jelly grape what ingredient we run out of first if you had 28 slices of bread 120 g of peanut butter in 135 g of grape jelly
Answer:
Grape Jelly
Explanation:
There is enough for at least 14 sandwiches with the bread:
28/2 = 14
There is enough for at least 10 sandwiches with the PB.
120/12 = 10
However, there is only enough for 9 sandwhiches with the grape jelly.
135/15 = 9

When hair sticks to your comb as it is being combed, this is a result of
a. charging by friction
b. charging by conduction
c. charging by induction
d. grounding
The correct answer is A. Charging by friction
Explanation
When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction
This reaction supports the Law of Conservation of Mass (hint: is the equation balanced?):
2KOH ® K20 + H2O True or
False
Answer:
False
Explanation:
Left:
K = 2 atoms
O = 1 atoms
H = 1 atoms
Right:
K = 2 atoms
O = 1 atoms
H = 2 atoms
O = 1 atoms
As you can see both sides do not have the same amount of atoms, therefore it is not balanced.
Hope this Helps!!:)

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 60g is the mass of 5.00 moles of carbon.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically, the formula for mole can be given as
mole of carbon =given mass of carbon ÷ molar mass of carbon
number of mole of carbon= 5.00 moles
mass of carbon=?
molar mass of carbon= 12.0107 grams
Substituting the values in above formula we get
5.00 moles = mass of carbon ÷12.0107 grams
On calculations, we get
mass of carbon =60g
Therefore, 60g is the mass of 5.00 moles of carbon.

The picture shows that a physical change has taken place which converted ice to water.
What are physical changes?
Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

what is the formula name for Co3N2
Answer:
Cobaltous Nitride,I think so anyway.......
The formula name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride.
In the compound [tex]Co_{3}N_{2}[/tex], the Co represents the chemical symbol for cobalt, and the N represents the chemical symbol for nitrogen. The subscript numbers indicate the ratio of atoms present in the compound.
To name the compound, we determine the charge of the cobalt ion based on the ratio of cobalt and nitrogen atoms. In this case, since there are three cobalt atoms and two nitrogen atoms, each cobalt atom has a 2+ charge.
Therefore, the correct name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride. The Roman numeral II is used to indicate the cobalt ion's charge.

If the fuel had a mass of 2g,
how much heat energy does
each gram of fuel release?
Answer:
Explanation:
Worked example – calculating energy per gram of fuel
Energy given out = mass of water × 4.2 × temperature change.
Energy measured in joules, J.
4.2 is the specific heat capacity of water, J/g°C.
Temperature change = temperature of water after heating – temperature of water before heating.
