Explanation - The mean deal with science is that it allows people to carry on research in an organized manner to find or make new discoveries and inventions.
The basic purpose of science is to try new things or ways to get an outcome by constant perseverance on research and negating the ways that don't work thus giving and improving knowledge of what is correct and what is not to make a new Discovery or invention.
Im working on science too!! I would help you but the attachment isn't pulling up..
The correct answer is d. <span>6H20 + 6CO2.
The reactant in the chemical reaction </span>6H2O + 6CO2 ---> C6H12O6 + 6O2 is 6H20 + 6CO2. Remember that the reactant is always at the left side of the equation. So the correct answer is <span>6H20 + 6CO2 since it's in the left of the equation. I hope this answer helped you. </span>
The empirical formula of the compound is SiCl₄.
<h3>Empirical formula of the compound</h3>
mass of silicon = 28 g/mol
mass of chlorine = 35.5 g/mol
<h3>molar ration: </h3>
Si = 8.56/28 = 0.306
Cl = 43.2/35.5 = 1.216
<h3>Combining ratio</h3>
Si = 0.306/0.306 = 1
Cl = 1.216/0.306 = 4
empirical formula = SiCl₄
Thus, the empirical formula of the compound is SiCl₄.
