<u>Answer:</u> The given number in scientific notation is 
<u>Explanation:</u>
Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
We are given:
A number having value = 0.000000093425
Converting this into scientific notation, we get:
Hence, the given number in scientific notation is
1. an alpha particle
gamma rays are formally massless, positrons and electrons (beta particles) have negligible mass, but alpha particles have about 4 amu of mass
Answer:
2.857 × 10⁻⁴ M
Explanation:
First, we will calculate the molarity of the solution 1.
M = mass of solute / molar mass of solute × liters of solution
M = 0.5028 g / 879.9 g/mol × 0.100 L
M = 5.714 × 10⁻³ M
We can find the concentration of the final solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 5.714 × 10⁻³ M × 5 mL / 100 mL
C₂ = 2.857 × 10⁻⁴ M
Ionic Bonding:
This type of bonding occurs when atoms want to fulfil their valence shells by taking/giving electrons to other atoms. This, leads to completed valence shells in most cases and ionisation of both elements. The opposite charges cause the elements to stick together because opposites attract.
Covalent Bonding:
This type of bonding occurs when electrons are shared between atoms to each fill up their own valence shells by sharing. The balance between the attraction forces and repulsion forces between the shared electrons is called covalent bonding.
Hope I helped :)
