Mass is the property of a physical body and the resistance to acceleration when a net force is applied on the body.
The atomic mass of sodium (Na) is = 22.98
The atomic mass of nitrate (N) is = 14.00
The atomic mass of oxygen (O) is = 15.99
The sodium nitrate (NaNO3) consists of the atomic masses of Na+N+(O)3 = 85 grams
Therefore, the mass of 6.5 mol of sodium nitrate is = 6.5 * 1 mol of NaNO3
= 6.5 * (85)
= 552.50 grams
The three group 4 elements that occur naturally are titanium, zirconium, and hafnium. The first three members of the group share similar properties; all three are hard refractory metals under standard conditions.
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.
