In two or more complete sentences explain how to balance the chemical equation,
Ca + N2 ⟶ Ca3 + N2 and include all steps.
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

Explanation:
Jim ran 200 meters in 30.4 seconds. Mac ran 100 meters in 30.4 seconds. Who ran faster?
Jim, because his distance divided by time is less
Jim, because he ran a greater distance in the same time
Mac, because he ran the same distance in fewer seconds
Mac, because his rate of change of distance over time was constant
Jim, because he ran a greater distance in the same time :)

How does the amount of water in a glass affect the pitch of the sound it produces?
Answer:
the more water the higher the pitch the less water the lower it is
Answer:
The glass with the most water has the lowest pitch. The glass with the least amount of water has the highest pitch.
Explanation:Tapping the glasses causes the air to vibrate. When the air column is shorter, the air vibrates faster and the pitch is higher.

Which of Newton's 3 Laws explains a rocket lifting off? *
Law of inertia
Law of Acceleration
Law of Action-Reaction
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!

Answer:
we'll, metal cups are usually used for coffee so people who bring their coffee to work from home can keep it warm. metal cups however do not keep things cold, it may feel cold on the outside, but that's an illusion. plastic doesn't do much, its just a cold insulator. it is good at keeping things cold because it is a poor heat conductor. foil can keep things warm, but it can also keep things cold. do what you will with the info lol.
Answer:
1.H & E
Explanation:
metal cups keep things hot and cup H is made to keep things both cold and hot but the other cups will melt if you put hot stuff in them and number three is an answer it your self because it says to enter your answer so........

Select all that apply. Wire is typically made out of metal because metal
Question 10 options:
Is malleable
Is ductile
Is brtittle
Conducts electricity
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.
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.
