It has 9 protons, 9 electrons and 10 neutrons.
<u>Answer:</u> The mass of water produced is 507.6 g
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of glucose = 846 g
Molar mass of glucose = 180 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of glucose produces 6 moles of water
So, 4.7 moles of glucose will produce = of water
Molar mass of water = 18 g/mol
Plugging values in equation 1:
Hence, the mass of water produced is 507.6 g
Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
Answer:
The answer is "208 mL".
Explanation:
In dilutions of different concentration, its initial volume for glucose solution V1 can be obtained by using the following formula, i.e.
The solution of 520 mL final glucose solution thus requires 208 mL of glucose solution of .
