Answer:
A: Antibonding molecular orbitals are higher in energy than all of the bonding molecular orbitals.
Explanation:
Molecular orbital theory describes <u>covalent bonds in terms of molecular orbitals</u>, which result from interaction of the atomic orbitals of the bonding atoms and are associated with the entire molecule.
A bonding molecular orbital has lower energy and greater stability than the atomic orbitals from which it was formed. An antibonding molecular orbital has higher energy and lower stability than the atomic orbitals from which it was formed.
Electrons in the antibonding molecular orbital have higher energy (and less stability) than they would have in the isolated atoms. On the other hand, electrons in the bonding molecular orbital have less energy (and hence greater stability) than they would have in the isolated atoms.
Answer:
Microorganisms have uses and benefits across all aspects of human life. From the bacteria that help humans digest food to the viruses that help plants resist heat, bacteria, viruses and fungi – when used properly – are key components in food, medicine, agriculture and other areas. In the future, they may even be core components of infrastructure and other new technologies.

A. Variables, this is because you can choose what you're testing
Answer:
2.8212 g
Explanation:
The reaction of copper sulfate with zinc is shown below as:
Given that :
Amount of zinc = 2.9 g
Molar mass of zinc = 65.38 g/mol
The formula for the calculation of moles is shown below:
Thus, molesare:
From the reaction,
1 mole of zinc on reaction forms 1 mole of copper
Thus,
0.0444 moles of zinc on reaction forms 0.0444 mole of copper
Mass of copper = moles×Molar mass
Molar mass of copper = 63.54 g/mol
<u>Mass of copper = 0.0444 ×63.54 g = 2.8212 g</u>
