Answers

Answer:

Sugar

Explanation:

This is because water and carbon dioxide are required during photosynthesis. Oxygen along with glucose, that is a type of sugar is produced. The oxygen is diffused out in to the air, while the sugars are stored in the leaf thus light energy captured during photosynthesis is stored as 'sugar'

Based upon your knowledge of metallic activity, which element would most readily react with water?

A) Li
B) Zn
C) Cu
D) Fe

Answers

Answer:

d

Explanation:

Of the given options, Lithium (Li) would most readily react with water.  

• The substances that spontaneously go through a chemical reaction with water, as they are highly reducing in nature are known as water reactive substances.  

• The alkali metals and the alkaline earth metals are the metals that reacts the most with water.  

• In the periodic table, the alkali metals, that is, lithium, sodium, potassium, rubidium, caesium, and francium are the most reactive metals.  

• They all react explosively and vigorously with cold water leading to the displacement of hydrogen.  

• The alkaline earth metals are the second most reactive metals in the periodic table apart from Be, which does not react with water.  

Thus, Li is the alkali metal that reacts readily with water.

Avogadro's number 6.02 X 10^23 is used in chemistry to measure something like electrons, atoms, elements etc. Question 1 options:

True
False

Answers

Answer:

I'm pretty sure it's false. It is used to measure the amount of Moles in an element.

I'm sorry if this is incorrect.

The Avogadro number is the number of atoms in one mole of a substance. Hence, it can be used to determine the number of atoms, electrons or molecules. Thus, the statement is true.

What is Avogadro number ?

Any substance containing 6.02 × 10²³ atoms is called one mole of the substance. This number is called Avogadro number. The name came from the scientist Avogadro.

This number measures the number of atoms in specific moles of an element or compound. One mole of a compound contains Avogadro number of molecules.

The mass of an element containing Avogadro number of atoms is called its atomic mass. Similarly, the mass of a compound that contains Avogadro number of molecules, that is one mole of the compound is called its molar mass.

Hence, we can calculate the number of atoms in a given number of moles of an element or compound by knowing that one mole of it contains Avogadro number of atoms.

Where does heat come from

Answers

Answer:

All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.

Explanation:

You can calculate the mechanical energy of an object by _____.
A. first calculating its thermal energy
B.adding its chemical energy and its electrical energy
C. subtracting its potential energy from its kinetic energy
D. combining its potential energy with its kinetic energy

What are the four ions formed when sodium chloride undergoes electrolysis?

Answers

Answer: The four ions formed are [tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]

Explanation:

Electrolysis is the process where electricity is used to drive chemical reactions.

In the electrolysis of aqueous solution of sodium chloride, hydrogen gas produces at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode and the sodium hydroxide remains dissolved in the solution.

The reactions will be :

[tex]NaCl\rightarrow Na^++Cl^-[/tex]

[tex]H_2O\rightarrow H^++OH^-[/tex]

Hence, electrolysis of an aqueous solution of sodium chloride lead to the formation of four ions,[tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]
