Explanation:Heterozygous means that the dominant and recessive alleles are written genotypically.
I believe the correct answer from the choices listed above is option B. A double-replacement reaction happens when atoms in one compound switch places with atoms in another compound. <span> It is a type of chemical </span>reaction<span> where two compounds </span>react<span>, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places. Hope this answers the question.</span>
Answer:NaOH
Explanation:all are acids except NaOH
Answer:
160.9 mol ≅ 161.0 mol.
Explanation:
- It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms (formula units).
Using cross multiplication:
1.0 mole of Fe(NO₃)₃ contains → 6.022 x 10²³ formula units.
??? mole of Fe(NO₃)₃ contains → 9.69 x 10²⁵ formula units.
<em>∴ The no. of moles of He contains (9.69 x 10²⁵ formula units)</em> = (1.0 mol)(9.69 x 10²⁵ formula units.)/(6.022 x 10²³ formula units) = <em>160.9 mol ≅ 161.0 mol.</em>
