3. What Are The Inferences You Can Make From Each Of The Activity Above?

Answers

Answer 1

A reagent is a chemical substance that cause a chemical reaction or used to test the one. In the given activity, different reagents are used to predict the compound. Starch gives blue color on reaction with iodine, glucose will have brick red precipitate with Benedict solution, and proteins will have reddish brown color with Millon's reagent.

Why reagents are used to test compounds?

The reagents when combined with specific compounds performs specific reaction which helps to determine the presence of particular compound.

In the given activity,

If in the first test, if the iodine turns color to blue this will indicate the presence of starch.In the second test, if on adding Benedict solution, brick red precipitates formed, this indicates the presence of glucose.In the third test, on adding Millon's reagent the protein in the solution will form reddish brown color.

Thus, these were some inferences that can be made from the given activities.

Energy efficiency = useful energy output/total energy input x 100(%)

If a power plant uses 100 units of energy to create electricity and the output is 5 units, where does the 95% of the energy input go?

A: Lost as heat
B: Lost as gas
C: Escapes the system as potential energy

Answers

Answer:

no

Explanation:

No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance

Electrons in an outer or
shell determine the chemical reactivity of atoms.

Answers

Answer:

The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.

Explanation:

Electrons in an atom's outermost shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons, play a crucial role in determining the chemical reactivity of the atom.

What is an electron?

The chemical reactivity of an atom depends on its ability to gain or lose electrons, which is determined by the number of valence electrons in its outermost shell. The valence electrons are the ones that are involved in chemical bonding, which is the process by which atoms combine to form molecules. Atoms with incomplete valence shells tend to be more reactive because they have a strong tendency to gain or lose electrons to achieve a stable configuration. A stable configuration is achieved when an atom's outermost shell is completely filled with electrons.

Hence,  Electrons in an outer shell determine the chemical reactivity of atoms; this is true as the electrons in an atom's outermost shell, also known as its valence electrons,

What is DNA?

DNA is a hereditary material  which is present in human beings as well as all other living organisms.  Every cell which is present in an organism's body has DNA  which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.

Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.

DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate  sugar are together called as nucleotides.
