Answer:
balanced chemical equation is
2 SiO₂ + 3 C₂ = 2 SiC + 4 CO
Answer:
The correct answer is - the number of days the rainwater stands in the jars.
Explanation:
The independent variable or the manipulating variable is a variable in a research or study is the variable which affects the dependent variable or the variable that is going to measure in the study.
In the study, variables that recieves the treatment and changed in every subject are independent variables and in this study number of days the rainwater standing in various jars that might affect the growth of the bacteria in rainwater.
<span>Like the previous post states, the number of valence electrons (typically the group number for nonmetals)relates directly to the number of covalent bonds available. Additionally, when you exceed this number you create a cation and when you are less the number of potential bonds, you have created a anion.

1) As carbon dioxide changes from solid state to gaseous state, the particles gain energy and move faster.
The molecule of CO2 gain energy which results in greater separation of each other and freer and faster movement
2) When a substance undergoes a change of state its mass does not change
