Using the equation below, how many liters of water can be made from 7.6 L of oxygen gas at STP?

Answer:

False

Explanation:

This isn't true. Energy is neither created nor destroyed. Heating something makes the particles move faster, but no new energy is created. Cooling results in slower particles, but once again, no energy loss.

The given statement "when something heats up, new energy is created, and when something cools down, energy is destroyed" is absolutely false.

According to the first law of thermodynamics which states that the energy of a closed system must always remain constant. It can neither be created nor destroyed without any interference from outside. This is the principle of physics.

The same concept is described by chemistry through the name known as The law of conservation of energy. This states that in a chemical reaction energy can never be created or destroyed.

When you heat up something, the movement of particle increase, not energy. Similarly, when you cool down something, the movement of particles or atoms within that decreases, not energy.

Therefore, the given statement "when something heats up, new energy is created, and when something cools down, energy is destroyed" is absolutely false.

Explanation:

i just know lol

........

Answer:

Highest boiling point - 0.43 m Urea

Second highest boiling point - 0.20 m NiSO4

Third highest boiling point - 0.19 m NH4I

Lowest boiling point - 0.17 m NH4NO3

Explanation:

We know that;

ΔT = kb m i

Where;

ΔT = boiling point elevation

kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

For NiSO4 , NH4I  and NH4NO3 , the Van't Hoff factor, i = 2

But for Urea, the Van't Hoff factor, i = 1

We also have to consider both the values of the molality and Van't Hoff factor , knowing that a higher molality and a higher Van't Hoff factor leads to a higher ΔT and consequently a higher boiling point.

This facts above account for the arrangement of substances shown in the answer.

39.9477amu is the average atomic weight of Argon

Explanation:

The average atomic weight is defined as the sum of the products of the atomic weight of each isotope times its abundance. For the Argon the average atomic weight, X is:

[tex]X = 0.996*^{40}Ar + 0.00337*^{36}Ar+0.00063*^{38}Ar[/tex]

[tex]X = 0.996*39.9624amu + 0.00337*35.9676amu+0.00063*37.9627amu[/tex]

X = 39.9477amu is the average atomic weight of Argon

Thus, random error primarily affects precision. Typically, random error affects the last significant digit of a measurement. The main reasons for random error are limitations of instruments, environmental factors, and slight variations in procedure.

Explanation:

You just gotta match the moles:

moles of NaOH = 0.02737 L * 0.2115 M = 0.005789 mol of NaOH. The amount of moles of HCl it can neutralize should be the same since they are in a 1:1 ratio. Therefore, you can do moles of NaOH divided by 0.003745L to get the answer. It turns out to be 0.1546M.

The increasing order of average molecular velocity at 25 degrees Celcius is:

BrF< NO₂<HCl<H₂O<He

It is defined whether it is normal speed, root mean square speed and most likely speed. It should be relative to the square to the square root of outright temperature.

The gas with the minimum molar mass will have the highest molecular speed.

Thus, Helium is having the lowest molar mass, therefore it will have the highest molecular velocity.

Answer:

C₅H₈NO₄Na

Explanation:

Step 1: Given data

Step 2: Divide each percentage by the atomic mass of the element

Na: 13.6/22.99 = 0.592

C: 35.5/12.01 = 2.96

H: 4.8/1.01 = 4.75

N: 8.3/14.00 = 0.592

O: 37.8/16.00 = 2.36

Step 3: Divide all the number by the smallest one, i.e. 0.592

Na: 0.592/0.592 = 1

C: 2.96/0.592 = 5

H: 4.75/0.592 ≈ 8

N: 0.592/0.592 = 1

O: 2.36/0.592 ≈ 4

The empirical formula of MSG is C₅H₈NO₄Na.

Answer:

89%

Explanation:

The computation of the sample percentage is sugar is shown below:

As we know that

The mass of the total sample mixture is

= Mass of salt + mass of sugar

= 0.8920

And, the mass of salt is 0.0982 g

So, the mass of sugar is

= 0.8920 - 0.0982

= 0.7938 g

Now the percentage of the sample is sugar is

= 0.7938 ÷ 0.8920

= 89%
