Covalent bond is the term that is being used to describe the bonds in the compounds that are created due to the sharing of one or more electrons. One of the best example of the simplest covalent bond is the bond that is being created when two isolated hydrogen atoms come together to form an H2 molecule. An isolated hydrogen atom has one proton and electron being combined by the force of attraction from the opposite-charged articles. When a pair of isolated hydrogen atom combines, two forces of attraction are created coming from each of the isolated hydrogen atom.
I believe it is electronegativity..... because electronegativity is the ability of an atom to attract electron to itself
Answer:
a = 0.57 m/s²
Explanation:
Given data:
Mass = 70 kg
Force = 40 N
Acceleration = ?
Solution:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Now we will put the values in formula.
a = 40 N / 70 Kg
a = 40 Kg. m/s² / 70 Kg
a = 0.57 m/s²
The time needed for a substance becomes half of it mass is called half-time, after. In this case, the half time is 100 minutes. Then to know how much substance remain after 200 minutes the equation would be:
Substance remains= 1/2^(time/half-time) x substance initial mass
Substance remains = 1/2^(200 minutes/100minutes) x 1 times= 1/4 times
Explanation:
Let the mass of the compound be 100g.
Mass of Sulfur = 96g.
=> Moles of Sulfur
= 96g / (32.07g/mol) ≈ 3
Mass of Hydrogen = 4g.
=> Moles of Hydrogen
= 4g / (1.008g/mol) ≈ 4
Mole ratio of Sulfur to Hydrogen = 3 : 4,
Empirical formula of compound = S3H4.
