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.

How many grams are in 1.946 moles of nacl
Ilia_Sergeevich [38]

Answer:

113.8g

Explanation:

Statement of problem: mass of 1.946mole of NaCl

Given parameters:

Number of moles of NaCl = 1.946mole

Unknown: mass of NaCl

Solution

To find the mass of NaCl, we apply the concept of moles which expresses the relationship between number of moles and mass according to the equation below:

                        Number of moles = \frac{mass}{molar mass}

To find the molar mass of NaCl:

                         the atomic mass of Na = 23g

                                atomic mass of Cl = 35.5g

                Molar mass of NaCl = (23 + 35.5) = 58.5gmol⁻¹

Mass of NaCl = Number of moles x molar mass of NaCl

Mass of NaCl = 1.946 x 58.5 = 113.8g

Which transition metals usually form only one monatomic cation? select all that apply.
lyudmila [28]

Zn, Cd, and Ag are transition metals that usually form only one monoatomic cation.

A monatomic cation is a cation made of only one atom.

Cations are positively charged ions, in this example Ag⁺, Cd²⁺ and Zn²⁺.

These cations form only one type of ion, while iron and copper form more than one type of cations.

Iron and copper form cations with different charges (Fe²⁺, Fe³⁺, Cu⁺, Cu²⁺).

It depends on electron configuration which type would be formed.

Electron configuration of zinc atom: ₃₀Zn 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²

Transition metals are elements in the d-block of the Periodic table.

When water changes state from a liquid to a solid is energy absorbed or lost?
Brrunno [24]

Answer:

Loses

Explanation:

liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.
