utes the students observed the balloon starting to inflate. Explain what was happening in the flask and balloon to cause it to inflate. Pick the statement that DOES NOT apply to the changes.
A) The dry ice changed from a solid to a gas at room temperature.
B) The carbon dioxide gas had more kinetic energy than the solid carbon dioxide.
C) Rapidly moving carbon dioxide gas molecules moved into the balloon and inflated it.
D) As the temperer increased, the solid carbon dioxide changed phase: solid - liquid - gas.

Explain the connection between reactants, products and limiting reactant.
balu736 [363]
In easy words the connection between Reactants, Products and Limiting reactants is as follow,

Reactants and Products:
                                       Reactants are the starting materials for the synthesis of final synthesized materials called as products.

Example:
                 CH₄  +  2 O₂     →      CO₂  +  2 H₂O

In above reaction Methane (CH₄) and Oxygen (O₂) are the reactants while, CO₂ and H₂O are the products.

Reactants, Products and Limiting Reactants:
                                                                       Considering the same example it is seen that for one mole of CO₂ two moles of O₂ are required to completely convert into CO₂ and H₂O. If either of the reactant is taken less than the required amount then it will act as a limiting reactant because it will consume first leaving the second reactant present in excess as compare to it. Hence, we can say that the limiting reactant is the starting material which controls the amount of product being formed.

Why are all atoms electrically neutral?
Anna11 [10]

Answer: Atoms are neutral if they have the same number of charged protons and electrons, balancing positive and negative charges. ... This is because water itself has slight charges. Answer 7: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
