Answer:
B.
He could breed his peach plants with peach plants that can survive the frost.
Explanation:
Tom can best solve his problem by breeding his peach plants with the ones that can survive the frost.
- This is known cross breeding
- The goal of cross breeding is to produce offspring that contains the traits of both of the parents or an improved hybrid.
- If Tom can cross breed the failing peaches with the successful winter resistant ones, he can ensure better production.
- The new hybrid will therefore will be genetically superior and adapted to the prevailing environmental changes.
The number of moles of H atoms in 15.2 grams of pure ice is 0.850 moles
The number of moles of O atoms in 15.2 grams of pure ice is 13.50 moles
<h3>What is an atom?</h3>
An atom is a smallest indivisible particle of a chemical element that is capable of independent existence.
- Pure ice contains the H2O molecules and the molar mass of H2O is 18.02 g/mol
Using the relation:
- number of moles = mass/molar mass
The number of moles of H2O = 15.2 grams/18.02 g/mol
number of moles of H2O = 0.8435 moles
If the atomic mass of H and O are as follow:
- the atomic mass of H atom is = 1.00784 g/mol
- the atomic mass of O atom is = 15.999 g/mol
Then:
the number of H atoms in 15.2 grams of pure ice = mass of H atom × molar mass of H2O.
the number of H atoms = 0.8435 mol × 1.00784 g/mol
the number of H atoms = 0.850 moles
the number of O atoms in 15.2 grams of pure ice = 0.8435 mol × 15.999 g/mol
the number of O atoms = 13.50 moles
