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>

The formation of a white cloud
saw5 [17]
Most clouds are white. That's because water and ice particles that make up a cloud have just the right amount and sizes to scatter light in all possible wavelengths. When light of practically all wavelengths combine, the result is white light.

Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? Arrange the substances with polar
KengaRu [80]

Covalent bonds can be classified as nonpolar and polar covalent given the electronegativity difference between two atoms (ΔEN).

Nonpolar covalent bond electrons are shared equally between two atoms, polar covalent bond electrons are shared unequally, atoms have partial charges, ionic bond electrons are completely transferred to one atom, full charges present. Therefore, the greater the electronegativity difference, the greater the bond polarity. Let's determine the types of bonds present in the compounds and arrange the ones with polar covalent in order of increasing ΔEN. Sulfur and oxygen are both nonmetals so the substance is covalent. Sulfur has EN = 2.5 and oxygen has EN = 3.5. Since there is an electronegativity difference, the S−O bonds in the substance can be classified as polar covalent bonds.

when a number in scientific notation contains a significant zero, is that zero also significant in the expanded notation? give t
AlexFokin [52]
I believe you are referring zero as the exponent. <span>Any number (except 0) with exponent 0 is defined to mean 1.
</span>

For one thing, there is a rule: 

<span> a^m/ a^m = a^m-m = a^0

</span>But (when a is not equal to <span>0),
</span>
a^m/ a^m = 1

Therefore, we must define a^0 as 1.
