M₁ x V₁ = M₂ x V₂
2.5 x V₁ = 0.50 x 100.0
2.5 x V₁= 50
V₁ = 50 / 2.5
V₁= 20 mL
hope this helps!
Answer:
ik that its not 48 because i answerd 48 and i got it wrong and im pretty sure its also not 144
Explanation:
Atomic Radius increases from Left to Right and Top to Bottom
Ionization Energy increases from Left to Right and Bottom to Top
Electronegativity increases from Left to Right and Bottom to Top
By eliminating the other incorrect answers, the best answer is (b) <span>chemical reactions involve bonding and nuclear reactions involve releasing particles. Chemical reactions are mainly concerned with bonding between chemicals (though sometimes electrons are released but another atom/ion will absorb it), unlike nuclear reactions which always involves releasing subatomic particles.</span>
The kinetic model theory states that the particles of gases behave as perfectly elastic spheres, exhibiting elastic collisions, where kinetic energy is conserved, whenever they hit something.
