The chemical reaction is the combination of atomic orbitals of different or same elements. The new product formed can be a molecule or compound which is having different physical and chemical properties than the initial substances.
What are chemical reactions ?A chemical reaction is a chemical change that make the formation or breaking or both of chemical bonds. There are different types of chemical reactions such as synthesis reactions, decomposition, combustion, displacement reaction etc.
The product of these reactions depends on how the elements in the reactant side reorganize. The physical and chemical properties of the new product will be different from that of the initial substance.
The interaction of two atoms can be of different types depends on their nature and can bond through ionic bonding, covalent bonding, hydrogen bonding etc.

Potassium (K) is found in Group 1. Fluorine (F) is found in Group 17. When these atoms bind, which will form the positive ion, and which will form the negative ion? Why? Hint: Refer back to the periodic table.
Answer:
The oppositely charged ions form an electrostatic attraction, which is the ionic bond. The compound potassium fluoride (KF) results, and since the potassium and fluoride ions have equal but opposite charges, the compound is neutral (but not the individual ions in the compound).

If you don’t discover a management technique to restore nutrients to your soil, what will happen to your crops? Select all that apply
A.Your vegetables will win prizes for being unusually large.
B.Anything you grow will be at high risk for pesticides and diseases.
C.Your land could stop producing vegetables altogether.
D.Your land will be worth less money.
If crops are not getting proper nutrients from soil we may have to apply fertilizers which adversely affect the soil if no nutrient is restored to soil, it will not produce vegetables and your land will be worth less money. Thus, options C and D are correct.
What are nutrients?Nutrients are ions, minerals and proteins that is very essential for living things. Without proper nutrition, the growth of both plants and animals become will be declined.
Plants needs some elements such as nitrogen, potassium, calcium, phosphorus etc. for their growth. They absorbs these ions and water from soil and distribute all over its body through channels.
If plants are getting no nutrients from the soil their will not grow and no new vegetables will be formed in such a land where there on management to restore soil nutrients.
In such situations, we have to apply fertilizers which have may bad impacts too. Hence, without nutrients the vegetables will not grow and the land will be worth less of money.

When one thing in a _____ circuit stops working, the whole circuit stops working.
Answer: When one thing in a electric circuit stops working, the whole circuit stops working.
Explanation:
The circuit in series works in a manner that, when one thing stops in the circuit, the whole circuit stops.
What is a circuit?A circuit is the way of passage of electricity including the electrical devices, electrical wires, energy source such as battery etc. There are two types of circuits namely parallel circuit and series circuit.
In a parallel circuit, all the components are arranged in a parallel fashion. For instance if there are three resistors, each resistors will be parallel each other resistors.
In series circuits, all electrical components are arranged in a series. Thu for a group of bulbs, the second tail of first bulb is connected to the first tail of second bulb and so on. So that, the the effect of electrical current will be same for all.
Therefore, in a series circuit When one thing stops working, the whole circuit stops working.

Answer:
Engines can overheat for many reasons. In general, it's because something's wrong within the cooling system and heat isn't able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Explanation:
HOPE IT WILL HELP U
Answer:
There might be some problem in the engine's cooling system.
Explanation:
There are many reasons why your car could be overheating, but the basic process of overheating involves a problem with the vehicle's cooling system that doesn't allow heat to leave the engine compartment. This is often due to a leak or blockage somewhere in the engine cooling system or other components.

Zinc chloride (ZnCl2) is used as a flux when joining metals. It also is used to fireproof and remove odor from clothing. Reacting the metal zinc (Zn) with hydrochloric acid (HCl) to produce zinc chloride and hydrogen (H2). Use the models above to demonstrate that mass is conserved when zinc reacts with hydrochloric acid.
Answer:
The atoms are just rearranged but there is no decrease or increase in the mass. A law fo conservation.
Explanation:
For my science class, we were doing Savvas too so I know the answer for this question.
According to the law of conservation of mass and as depicted in the model there are equal number of atoms of reactants and products , thus demonstrating that mass is conserved.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.
