Answer:
likely be the same
Explanation:
this is because we have one color that both atoms share (green). both sample 1 and sample 2 have green and another color. yet, since they share one color, they are likely similar
Answer:
50.8 g
Explanation:
Equation of reaction.
From the given information, the number of moles of methane = mass/ molar mass
= 15.4 g / 16.04 g/mol
= 0.960 mol
number of moles of oxygen gas = 90.3 g / 32 g/ mol
= 2.82 mol
Since 1 mol of methane requires 2 moles of oxygen
Then 0.960 mol of methane will require = 0.960 mol × 2 = 1.92 mol of oxygen gas
Thus, methane serves as a limiting reagent.
2.82 mol oxygen gas will result in 2.82 moles of water
So, the theoretical yield of water = moles × molar mass
= 2.82 mol × 18.01528 g/mol
= 50.8 g
To solve such this we must know the concept of chemical reaction and dehydration reaction. Therefore, dehydration means to remove water from a compound.

What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Dehydration is a chemical process in which removal of water molecules from a compound take place using suitable reagent. The best reagent for dehydration can be any reagent that is water loving.
Therefore, dehydration means to remove water.

Answer:
2.
Explanation:
When you put the paper in a solution, it will turn blue if it is basic, or red if it is acidic. If it does not change color, it is fairly neutral.
Density is Mass per Volume
so
0,8765 g/ml = Mass of Benzene / 250 ml
Mass of Benzene = 219,125 gram
so 250 ml of benzene is equal to 219,125 gram
