When farmers irrigate their crops, as much as 60 to 70 percent of the water _____. is ruined by pests, such as rabbits that are around the crops never reaches the crop is taken up by the plant is already contaminated by lead pipes
Answers
Answer:
Option (2)
Explanation:
The water in most of the region is generally pumped out of the ground for the purpose of irrigation. This rate of pumping is much higher than the rate of replenishment. The over-pumping of water leads to the lowering of the water table
About 60 to 70% of the water that is used for irrigation purposes does not reach the crop. It is because the water most of the time gets percolated down into the deeper zones. In addition to this, the water also leaks through the fractures that are associated with the canals and increasing rate of evaporation.
Thus, the correct answer is option (2).
Answer:b never reaches the crop hopefully helps

The correct answer is protons.

Hello! Let's solve this!
All atoms of the same element have the same number of protons. The isotopes of an element are chemical species that change the number of neutrons but not that of protons.
Then the different atoms of the same element differ in their protons.
The correct answer is protons.
All atoms of the same element have the same number of protons.
Protons are subatomic particles that are found within the nucleus of an atom. They have a positive electrical charge, which is equal in magnitude but opposite in sign to the negative charge of electrons. Protons are one of the three main types of particles found in atoms, along with neutrons and electrons.
The number of protons in an atom determines its atomic number and defines the element. For example, an atom with one proton is hydrogen (H), while an atom with six protons is carbon (C).

Further explanation:
Atomic electronic transition:
When an atom jumps from one energy level to another energy level, an atomic electronic transition is said to take place. This occurs either due to the absorption or emission of energy by the electron.
When the transition of an atom takes place from lower to higher energy levels by the absorption of energy, it is known as an absorption process. But when atom jumps from higher to lower energy level, it releases or emits energy and therefore the process is called an emission process.
The lowest energy state of an atom is called the ground state and its energy is known as zero-point energy. It is the most stable energy level of an atom. But the state that has energy higher than that of the ground state is called an excited state. Excited states are unstable as compared to the ground state and atoms in such states tend to lose energy and jump back to the lower energy levels.
Since the atom of the sample bright-line present in the excited states, a bright-line spectrum is observed only if it emits some amount of energy and comes back to the lower energy level.

The correct answer is:
B; A new substance forms.
Explanation:
A physical change, such as a state change or dissolving, does not produce a new substance, but an abundant change does. In a chemical reaction, the atoms and molecules that connect with each other are described as reactants. Chemical reactions happen when chemical bonds are broken and formed. If the molecules in a substance crash into each other with enough energy, some of the bonds in the molecules can break. The atoms can make new bonds with different atoms. A new substance forms.

C₂H₄O₂ = 12 * 2 + 1 * 4 + 16 * 2 = 60.
n = mass / molar mass
3.00 = m / 60.0
m = 3.00 * 60.0
m = 180 g of C₂H₄O₂
