In two or more complete sentences explain how to balance the chemical equation,

Ca + N2 ⟶ Ca3 + N2 and include all steps.

Answers

Answer:

to balance this equation, your going to put a 2 in front of the "Ca" then that makes the equation look like this "2Ca + N2 ⟶ Ca3 + N2" since the "Ca" had one atom, we added two more atoms

as we all know 1 + 2 = 3

then that gives us 3 "Ca's" on both sides

Conducts electricity

Answers

The correct answer is conducts electricity.

Metal is a really good conductor and is used in different electronics. It is also ductile, meaning it can be pulled into a thin wire.

Hope you have a wonderful day:)

Wire is typically made out of metal because metal is ductile and conducts electricity.

Ductility is the property of metal which makes it easy to be stretched into wire when drawn without breaking. This is a great feature for wires.

Conductor of electricity : The ability for a material to allow electricity to pass through it with ease shows it is a good conductor of electricity.This is also a great feature for wires.

The transition metal, copper is usually preferred for the manufacture of electrical wires This is because apart from being thermal resistant and cheap, it is very ductile and a good conductor of electricity.

Explain how getting sick can affect the body’s ability to maintain homeostasis.

Answers

Answer:

If your body manages to maintain homeostasis, then it means everything is in order, and you are in a healthy state. However, getting sick would indicate that your body conditions are not stable. This happens when the homeostasis is disrupted due to the interference of pathogens such as viruses and bacteria; for example, catching a flu virus would cause you to have a fever, cold, sore throat, and muscle aches. These symptoms eventually weaken your body and prevent you from performing your daily life functions.

The homeostasis has been affected while getting sick due to a change in temperature with disturbed electrolyte balance.

Homeostasis has been the ability of the body to maintain the equilibrium balance of the electrolytes, and elements for the proper functioning of the system.

The homeostasis has been maintained with the temperature and balance of the components in the preset limit. However with the change in the homeostasis results in the change in the balance and functioning of the organs.

While getting sick, we have changes in the body temperature along with electrolyte dis-balance. This results in disturbed homeostasis.

Which of Newton's 3 Laws explains a rocket lifting off? *

Law of inertia
Law of Acceleration
Law of Action-Reaction

Answers

Answer:

Newton's Third Law of Motion

Explanation:

A rocket expels hot gases at a very high pressure very quickly, and these gases have lots of energy, and according to Newton's third law, every action has an equal and opposite reaction. So, expel lots of gas at a high rate, and the energy of the gases being pushed out propels the rocket upward. Hope that helps!

Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.
