Answer:
A. mutation
Explanation:
mutation is called as change in genetic sequence (i.e, in DNA)
Answer:
The answer to your question is: b) Chemical property
Explanation:
Physical property: is when matter changes is physical state but it does not change its composition. For example, evaporation, condensation, sublimation, solidification, etc.
Chemical property, is when matter changes its composition because the reactants forms products.
In this question we have:
Mg + HCl ⇒ MgCl₂ + H₂↑
In this reaction, there are Mg and HCl, and after the reaction MgCl₂ and H₂ so, there was a change, and this reaction is a chemical change.
The independent variable would be the dry ice being placed in the water/other liquid (D) and the dependent variable would be the water/other liquid the dry ice (ID) is being placed in.
The 2nd one because it’s 2 and one
<u>Given:</u>
The initial energy of the electron Einitial = 16.32 * 10⁻¹⁹ J
The energy released i.e the change in energy ΔE = 5.4 * 10⁻¹⁹ J
<u>To determine:</u>
The final energy state Efinal of the electron
<u>Explanation:</u>
Since energy is being released, this suggests that Efinal < Einitial
i.e. ΔE = Einitial - Efinal
Efinal = Einitial - ΔE = (16.32 - 5.4)*10⁻¹⁹ = 10.92 * 10⁻¹⁹ J
Ans: A)
The electron moved down to an energy level and has an energy of 10.92 * 10⁻¹⁹ J
