why can't you turn pancakes back into the ingredients
Answer:
heat is added making it a chemical change
Explanation:
Answer:
With pancakes, the chemical reaction is between a leavening agent – such as baking soda & baking powder – & an acidic ingredient – such as buttermilk – producing tiny bubbles of carbon dioxide gas. These bubble form throughout the pancake, and are trapped as the batter cooks and solidifies
Explanation:
since there is a chemical reaction the pancakes cant be changed back into the ingredients after done.
In paper chromatography, is the substance being tested the solute or the solvent?
Answer:
Explanation:
This is an awfully good question. Think carefully about which is which.
A solvent is something that will dissolve the solute.
So the solvent will carry the solute up (say) chromatography paper. It is the solute.
How much will it cost in American dollars(USD) to fill a 15 gallon tank of gasoline in Canada, if the price of gasoline there is $1.07 Canadian dollars (CAD) per liter. The current exchange rate is ($1.00(USD)= $1.34(CAD), 1 L=1.06 qts, 1.61 Km= 1 Mile, 1 gal= 4 qts]
Answer:
It will cost 45.37 US dollars (USD) to fill a 15 gallon gas tank in Canada.
Explanation:
Two values are directly proportional when when one value increases, the other increases in the same proportion, or when one value decreases, the other decreases in the same proportion.
The rule of three makes it possible to solve proportionality problems effectively and quickly. It is a method of calculating an unknown value that is directly proportional to another known value.
Then, knowing the data a, b and c, and the fourth unknown data x, which will be the unknown to be solved, this value is calculated as:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{c*b}{a}[/tex]
You must calculate the cost in US dollars (USD) to fill a 15 gallon gas tank in Canada. You know that the price of gasoline is $1.07 Canadian dollars (CAD) per liter. If 1 L equals 1.06 qts, then you can say that the price of gasoline is $ 1.07 Canadian dollars (CAD) per 1.06 qts.
You can now apply a rule of three as follows: if 4 qts is equal to 1 gal, 1.06 qts is equal to how much gal is?
[tex]gal=\frac{1.06 qts*1 gal}{4 qts}[/tex]
gal= 0.265
Then you can say that the price of gasoline is $ 1.07 Canadian dollars (CAD) per 0.265 gal. So you can apply the following rule of three: if 0.265 gal costs $ 1.07 Canadian dollars (CAD), 15 gal how many Canadian dollars cost?
[tex]CAD=\frac{15 gal*1.07 CAD}{0.265 gal}[/tex]
CAD= $60.8 CAD
Finally, you can apply the following rule of three: if $ 1.34 (CAD) is equal to $ 1.00 (USD), $ 60.8 (CAD) is equal to how many US dollars (USD)?
[tex]USD=\frac{60.8 CAD*1USD}{1.34 CAD}[/tex]
USD= 45.37
It will cost 45.37 US dollars (USD) to fill a 15 gallon gas tank in Canada.
calculate the number of molecules in 52 gram of helium
Answer:
The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He.
1 g of He = (6.022 X 1023) / 4 atoms of He.
52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.

If an atom has 56 protons and 58 neutrons, how many electrons
would this atom have?
Because the protons = the electrons so the atom will have 56 electrons.
This atom would have 56 electrons.
Atomic Structure:
In a neutral atom, the number of protons and number of electrons are same which is equal to the atomic number of an atom.The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.So, it is given that;
Number of protons=56
Number of neutrons=58
Thus, number of electrons=56 (since, the number of protons and number of electrons are same)

Answer:
Temperature is one of the major factors that affects the rate of change of the liquid colour, this is because ; like when if you freeze hot water the ice formed will be clear transparent, while on the other hand, if we freeze cold water it would be foggy inside the ice. This change occurs because of the temperature difference of the cold and hot water.
