Lower the pH because increased number of free hydrogen ions
Answe
Explanation:
The answer is reduced effectiveness of pesticides.
Genetic engineering has a great advantage in vaccines production or in a pharmaceutical production of desired proteins, such as insulin, human growth hormone, etc. In plant genetic engineering increased drought and salinity tolerance will help plants survive in difficult conditions.
On the other hand reduced effectiveness of pesticides is a disadvantage of using genetic engineering. Genetically modified plants may develop resistance to pesticides, so pesticides are not effective as expected.
Answer:
1.30 m
Explanation:
First we <u>calculate the number of moles of solute in the solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- Converting 250 mL ⇒ 250 / 1000 = 0.250 L
- moles = 1.50 M * 0.250 L = 0.375 moles
Then we <u>calculate the mass of solvent</u>, using the <em>given volume and density</em>:
- 1.15 g/mL * 250 mL = 287.5 g
- Converting <em>287.5 g to kg</em> ⇒ 287.5 / 1000 = 0.2875 kg
Now we <u>calculate the molality of the solution</u>:
- molality = moles of solute / kg of solvent = 0.375 mol / 0.2875 kg
is the orbital hybridization of a central atom that has one lone pair and bonds to three other atoms.
<h3>What is
orbital hybridization?</h3>
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.
