Answer:
When atoms approach one another closely, the electron clouds interact with each other and with the nuclei. If this interaction is such that the total energy of the system is lowered, then the atoms bond together to form a molecule.
Explanation:
Answer: The rabbit population reached carrying capacity during the fourth year of the 10 years we set. Introduction: Population densityis the number of individuals in a population per unit of area. Some limiting factors only affect a population when its density reaches a certain level.
Explanation:
Explanation:
the molar mass of a compound can be caucaleted by adding the standar atomic masses.
Answer:
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards itself and becomes partial negative while the other atom becomes partial positive.
Non polar covalent bond:
It is the bond where both bonded atoms share the pair of electron equally.
For example:
Hydrogen gas (H₂) is non polar covalent compound because the electronegativity of both bonded atoms are same. No poles are created that's why this is non polar covalent compound.
Polar covalent bond:
It is the bond where both bonded atoms share the pair of electron unequally.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive and bond is polar.
The volume of the liquid sodium is 121.64 L
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can obtain the volume of the liquid. Details below
<h3>How to determine the volume of the sodium liquid</h3>
- Mass of liquid = 1.13×10⁵ g
- Density of liquid = 0.929 g/cm³
- Volume of liquid =?
Density = mass / volume
Thus,
Volume = mass / density
Volume of liquid = 1.13×10⁵ / 0.929
Volume of liquid = 121636.17 cm³
Divide by 1000 to express in liter
Volume of liquid = 121636.17 / 1000
Volume of liquid = 121.64 L
