Answer:
1. 17.3 MOLES OF WATER WILL PRODUCE 518.4 G OF GLUCOSE.
2. 87.4 G OF HNO3 WILL PRODUCE 7.86 G OF NITROGLYCERIN WHEN REACTED WITH EXCESS GLYCEROL.
Explanation:
1. How many grams of glucose is produced from 17.3 mole of water?
Equation:
6CO2 + 6H20 ------> C6H12O6 + 6O2
From the reaction, 6 moles of carbon dioxide reacts with 6 moles of water to produce 1 mole of glucose
So therefore,
6 moles of water = 1 mole of glucose
Since 17.3 mole of water was used, we can first calculate the number of moles of glucose produced:
Then, we have:
6 moles of water = 1 mole of glucose
17.3 moles of water = ( 17.3 * 1/ 6) moles of glucose
= 2.883 moles of glucose
So we say 17.3 moles of water produces 2.883 moles of glucose
At standard conditions, 1 mole of a substance is its molar mass
Molar mass of water = 18 g/mol
Molar mass of glucose = 180 g/mol
From the reaction:
17.3 moles of water produces 2.883 moles of glucose
17.3 * 18 g of water produces 2.833 * 180 g of glucose
= 518.94 g of glucose.
From 17.3 mole of water, 518.4 g of glucose will be produced.
2.
C3H5(OH)3 + 3HNO3 -------> C3H5(ONO2)3 + 3H20
3 moles of HNO3 reacts to produce 1 mole of nitroglycerin
Molar mass of HNO3 = ( 1 + 14 + 16*3) = 63 g/mol
Molar mass of nitroglycerin = ( 12 *3 + 1 *5 + 16*6 + 14*3) = 179 g/mol
3 moles of HNO3 = 1 mole of nitroglycerin
3 * 63 g of HNO3 = 179 g of nitroglycerin
if 87.4 g of HNO3 were to be reacted, we have:
189 g of HNO3 = 179 g of nitroglycerin
87.4 g of HNO3 = ( 87.4 * 179 / 189) of nitroglycerin
= 7.86 g of nitroglycerin
So therefore, 87.4 g of HNO3 will produce 7.86 g of nitroglycerin when reacted with excess glycerol.

Explanation:
What are two ways drugs can increase the concentration of neurotransmitters in a synapse?
Answer:
naturally, through diet or exercise or drugs, specifically receptor antagonists
Explanation:
diet/exercise - diet is self explanatory, since a healthy diet would mean that your body would be balanced, and wouldn't struggle with producing NTs
drugs - any type of drug will mimic the behavior of NTs, but receptor antagonists specifically will increase the concentration of neurotransmitters in a synapse. Antagonists would block the receptors, and thus the NTs that were intended for the blocked space, will not have anywhere to go. As a result, the NTs will stay in the synapse, and cause an increase in the concentration of NTs.

What is the volume of a 4.0M solution that contains 374 grams of KNO3?'
Answer:
0.93L
Explanation:
We'll begin by calculating the number of mole of present 374g of KNO3. This is illustrated below:
Mass of KNO3 = 374g
Molar mass of KNO3 = 39 + 14 + (16x3) = 101g/mol
Number of mole of KNO3 =..?
Mole = Mass /Molar Mass
Number of mole of KNO3 = 374/101 = 3.7 moles
Now, we can calculate the volume of the solution as follow:
Mole of KNO3 = 3.7 moles
Molarity = 4M
Volume =..?
Volume = mole /Molarity
Volume = 3.7/4
Volume = 0.93L
Therefore, the volume of the solution is 0.93L
Answer:
THE VOLUME OF A 4 M SOLUTION THAT CONTAINS 374 g OF KNO3 IS 0.93 L
Explanation:
Number of moles = concentraion * volume
Number of moles can also be written as:
number of moles = mass / molar mass
Calculate the molar mass of KNO3 where (K = 39, N = 14, 0=16)
molar mass of KNO3 = (39 + 14 + 16*3) = 101 g/mol
So therefore:
mass / molar mass = concentration * volume
where;
mass = 374 g
molar mass = 101 g/mol
concentration = 4 M
volume = unknown
Hence,
374 / 101 = 4 * V
V = 374 / 101 * 4
V = 374 / 404
V = 0.9257 dm3
The volume of a 4M solution that contains 364 g of KNO3 is approximately 0.93 L

A person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m. What is the efficiency rating of the jack? HINT: Use work formula first to solve for WORKout and again for WORKin...then use efficiency formula.
Answer:
The efficiency rating of the jack is 0.067.
Explanation:
We have, a person applies a force of 200 N over 1.5 m to a jack. The jack exerts a 1000-N force on a car a distance of 0.02 m.
It is required to find the the efficiency rating of the jack. It is equal to the ratio of output work to the ratio of input work. So,
[tex]\eta=\dfrac{1000\times 0.02}{200\times 1.5}\\\\\eta=0.067[/tex]
Thus, the efficiency rating of the jack is 0.067.
What is the molality of a solution containing 5 moles of a solute and 13 kg of a solvent?
Answer:
Morality of a solution = 0.38461
Explanation:
Given:
Amount moles in solution = 5 moles of solute
Amount of solvent = 13 kg
Find:
Morality of a solution.
Computation:
⇒ Morality of a solution = Amount of mole solute / Amount of solvent
⇒ Morality of a solution = 5 / 13
⇒ Morality of a solution = 0.38461
⇒ Morality of a solution = 0.385 (Approx)

the reaction below shows a system in equilibrium how would an increase in the concentration of chemicals affect this reaction?
Answer:
Option B. The equilibrium of the reaction would shift to the right.
Explanation:
According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.
Now, let us answer the question above.
From the question given above, the equation is:
A + B <===> C + D
Increasing the concentration of A will shift the equilibrium position to the right.
This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.

During which time interval does the substance exist as both a liquid and a solid
The time interval in which a substance exists as both liquid and solid is called ; Triple point
A triple point is a time interval in a substance when the pressure and temperature of the substance causes the substance to exist in more than one phase at a time. Substances that exhibit this characteristic are called non-Newtonian fluids.
A good example of a substance that exist in both liquid and solid form within this time interval is Potassium.
Hence we can conclude that the time interval in which a substance exists as both liquid and solid is called triple point.
