According to the quantum-mechanical model, which element will have similar chemical properties to an element with z = 7?

1 answer:

7 0

According to the quantum-mechanical model, Phosphorous will have have similar chemical properties to an element with Z = 7

Quantum mechanics models describe the opportunity of putting electrons inside an atom through describing the main power degree, energy degree, orbital (arbitrary degree), and spin of. The quantum mechanics version is based totally on quantum theory, which states that rely has wave-like properties.

The quantum mechanical model is primarily based on quantum concept, which states that matter nonetheless has wave-related residences. The quantum mechanical model is critical for knowledge chemistry since it describes how electrons arise in atoms and how these electrons determine the chemical and physical homes of an detail.

The maximum particular clocks within the global, atomic clocks, are able to use standards of quantum idea to measure time. They screen the specific radiation frequency needed to make electrons leap among energy tiers.

explanation :

Nitrogen (Z = 7) is in Group 15 element

and will have similar properties to other Group 15 elements, like Phosphorous etc.

Why are cells the building blocks of an organism.

ladessa [460]

Answer:A cell is the smallest unit of life, also called the 'building blocks of life' because cells multiply and differentiate to form a multicellular organism as well as give rise to new organism by forming gametes or reproductive spores.

Consider the neutralization reaction 2 HNO 3 ( aq ) + Ba ( OH ) 2 ( aq ) ⟶ 2 H 2 O ( l ) + Ba ( NO 3 ) 2 ( aq ) A 0.120 L sample

k0ka [10]

Answer:

The concentration of the HNO3 solution is 0.150 M

Explanation:

Step 1: Data given

Volume of the unknown HNO3 sample = 0.120 L

Volume of the 0.200 M Ba(OH)2 = 45.1 mL

Step 2: The balanced equation

2HNO3 + Ba(OH)2 ⟶ Ba(NO3)2 + 2H2O

Step 3: Calculate moles Ba(OH)2

moles Ba(OH)2 = molarity * volume

moles Ba(OH)2 = 0.200 M * 0.0451 L

moles Ba(OH)2 = 0.00902 moles

Step 4: Calculate moles of HNO3

For 1 mole of Ba(OH)2 we need 2 moles of HNO3

For 0.00902 moles of Ba(OH)2 we need 2*0.00902 = 0.01804 moles

Step 5: Calculate molarity of HNO3

molarity = moles / volume

molarity = 0.01804 / 0.120 L

Molarity = 0.150 M HNO3

The concentration of the HNO3 solution is 0.150 M
