What happens when you drop an egg on the ground from about 6 ft high?
Answer:
Gravity causes an object to fall to Earth when dropped. When the egg hits the ground with a given force, the ground exerts the same force back on the egg. If too large a force is delivered to the egg shell, the egg will crack.

4. Which elements have a completely full outermost energy level?
Answer:
Helium (He), neon (Ne), and argon (Ar), as group 18 elements, have outer electron shells that are full or satisfy the octet rule. This makes them highly stable as single atoms. Because of their non-reactivity, they are called the inert gases or noble gases.

PLEASE HELP!!
In the formula
1N2 +3H2 → 2NH3 + 1H2
1 diatomic nitrogen (1N2) and 3 diatomic hydrogen (3H2) produce 2 ammonia (2NH3) with 1 diatomic hydrogen (1H2) left over. How can you change the formula so no diatomic hydrogen (H2) is left over?
(1 point)
Remove a H2 molecule from the left side of the equation.
Remove a NH3 molecule from the right side of the equation.
There is nothing that can be done to use the leftover molecules.
Add another N2 molecule to the left side of the equation.
Answer:
Remove a H2 molecule from the left side of the equation.

Which of these describes an exothermic reaction? Please help, today is the last day to submit anything.
Answer:
A, Heat is released as the reaction happens.
Explanation:
Exothermic reactions release heat and/or light and is a reaction in which the overall enthalpy is negative. The one your mouse is hovering over explains Nuclear Fission. The third one explains an endothermic reaction, as heat is absorbed in the reaction. The product being cold is actually one of the key characteristics of an endothermic reaction. Two liquids being mixed that forms a solid is called a precipitate.
