Answers

Answer 1

Answer: a synthesis would be A+B-->AB its combining, decomposition is AB-->A+B, its the breaking up of a substance.

Which molecule contains a triple covalent
bond?
(1) H2 (3) O2
(2) N2 (4) Cl2

Answers

Answer: The correct answer is Option 2.

Explanation:

Covalent bond is defined as the b which is formed by the sharing of electrons between the atoms forming a bond.

Non-polar covalent bond is defined as the bond which is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..

For the given options:

Option 1: $H_2$

Hydrogen is the 1st element of the periodic table having electronic configuration $1s^1$

This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another hydrogen atom.

Option 2: $N_2$

Nitrogen is the 7th element of the periodic table having electronic configuration $1s^22s^22p^3$

This element needs 3 electrons to attain stable electronic configuration and will form triple covalent bond with another nitrogen atom.

Option 3: $O_2$

Oxygen is the 8th element of the periodic table having electronic configuration $1s^22s^22p^4$

This element needs 2 electrons to attain stable electronic configuration and will form double covalent bond with another oxygen atom.

Option 4: $Cl_2$

Chlorine is the 17th element of the periodic table having electronic configuration $1s^22s^22p^63s^23p^5$

This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another chlorine atom.

Hence, the correct answer is Option 2.

N2 because it has 5 valence atoms so it needs 3 to have 8, wich is the octet rule, so three is a triple covalent bond

If 20 milliliters of 4.0 M NaOH is exactly neutralized by 20 milliliters of HCL, the molarity of the HCL is

Answers

Volume of NaOH = 20 mL / 1000 = 0.02 L

Molarity NaOH = 4.0 M

number of moles NaOH :

n = M * V

n = 4.0 * 0.02

n = 0.08 moles of NaOH:

Finally we calculate the number of moles of HCl in the solution from the stoichiometry of the reaction :
HCl + NaOH = NaCl + H₂O

1 mole HCl ---------- 1 mole NaOH
? moles HCl --------- 0.08 moles NaOH

moles HCl = 0.08 * 1 / 1

= 0.08 moles of HCl

Volume of HCl = 20 mL / 1000 = 0.02 L

M ( HCl ) = n / V

M = 0.08 / 0.02

= 4.0 M

hope this helps!

Explanation:

Why is gold less reactive than iron?

Answers

The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid. Examples for metal-displacement reactions: Zinc can displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper.

Answer:

Iron has a standard electrode potential which is less than gold, which therefore means the gold is less reactive,

1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type deposits all energy into a single atom)
3 The particles that make up protons and neutrons and are thought to be basic units of matter are quarks.
