Answer:

this can be explained in terms of the Law of Conservation of mass because you just have to multiply the number of amount that was lost during the fire by 5

Explanation:

so if they lost 489 miles of mass from the fire, then u will have to multiply 489 by 5. 489x5=2445

Fire expends ENERGY which is a by-product of conversion of matter. 

<span>The calories or therms of a fire equal a certain amount of mass. </span>

<span>When MATTER (Electron) and ANTI-MATTER (Positron) collide they don't inhillate each other with nothingness, they always realse TWO gamma particles. </span>

<span>The ENERGY of the TWO gamma particles CONSERVES the MASS of the ELECTRON and The POSITRON </span>

<span>This is what Einstein meant by E=mc2 </span>

<span>ENERGY has physical properties than can be measured. </span>

<span>These properties equal the mass that no longer exists after you measure the mass BEFORE and AFTER </span>

<span>The AFTER MASS + the ENERGY MUST equal the BEFORE MASS to at least 99.999% </span>

<span>You must take heat, light and other PARTICLES into consideration. </span>

<span>Their MASS plus their ENERGY</span>

How many moles of chlorine are in 6.67x10^40 chlorine molecules?
sweet-ann [11.9K]
To solve for the number of moles, we simply have to use the Avogadros number which states that there are 6.022 x 10^23 molecules per mole. Therefore:
 
number of moles = 6.67 X 10^40 chlorine molecules / (6.022 x 10^23 molecules / mole)
number of moles = 1.108 x 10^17 moles

Draw the major product for the reaction of 1-butyne with water in the presence of catalytic TfOH (i.e., CF3SO3H). Then answer th
Mademuasel [1]

Answer:

2-Butanone

Explanation:

From the given information:

The presence of mercury as an acid catalyst brings about the addition of water to the triple bond which yields enol. Then, according to Markownikov's rule and after tautomerism has occurred, we have a methyl ketone ( 2- Butanone) as the product.

The answer regarding the transformation is addition and hydration.

A students drawing of a nitrogen atom is shown. What change would make the model more accurate?
zubka84 [21]

Answer:

C - show 7 neutrons in the nucleus

Explanation:

Use process of elimination:

-Answer A will not work because electrons are not in the nucleus.

-Answer B will change the atom's identity from nitrogen to fluorine; it will not work.

-Answer D will create a nitrogen ion, which is not what the prompt is asking for (an atom); it will not work.

The only logical answer is C, as that is the only one that is also true.

9. What is the name of the molecule?
AnnyKZ [126]

Answer:

3–methyl–2–butanol

Explanation:

To name the compound, we must:

1. Identify the functional group.

2. Give the functional group of the compound the lowest possible count.

3. Locate the longest continuous carbon chain. This gives the parent name of the compound.

4. Identify the substituent group attached.

5. Give the substituent group the lowest possible count.

6. Combine the above to get the name of the compound.

Now, let us obtain the name of the compound.

1. The functional group of the compound is Alcohol i.e —OH.

2. The functional group is located at carbon 2.

3. The longest continuous carbon chain is carbon 4 i.e butane. But the presence of the functional group i.e OH will replace the –e in butane with –ol. Therefore, the compound is butanol.

4. The substituent group attached is methyl i.e CH3.

5. The substituent group is located at carbon 3.

6. Therefore, the name of the compound is:

3–methyl–2–butanol.
