<h2>T
he mass of a liquid substance affected after it boils : C it stays the same</h2>
Explanation:
Matter
Anything that occupies space and has mass .
The states of matter are :
Solids
Liquids
gases
Interconversion of state of matter
Solid ------liquid -----------Gas
(on heating ) (on heating )
- One state can be changed in to another by changing the condition of temperature , pressure etc .
- When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
- This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing the state .But it doesn't change the mass .Hence mass of substance remains the same .
- Similarly , gas -----> liquid -----> solid
(on cooling ) (on cooling )
Each of the Isotopic mass * its Abundance Sum together divide by 100.
(179.946706*0.12 + 181.948206*26.5 + 182.9502245*14.3 + 183.9509326*30.64 + 185.954362*28.43 ) / 100
You get 183.84 (5s.f. ) or (183.8417786)

For #1, I'd say it's "It will usually bond to multiple atoms which can provide a total of 4 additional electrons."
2. Ionic (I'm quite certain because anions/cations (-1 & +1) are Ionic from what I recall, if that's true it's Ionic.
3. "comparison of the associated families to which the elements belong" and
"the difference in electronegativities" are what I would choose, as I mentioned in a comment earlier.
If I'm wrong let me know, but I am at least 80% sure that these responses are correct from what I remember in Chemistry.
Answer:
21.32 L
Explanation:
First, convert grams to moles using molar mass. C has a mass of 12 and O has a mass of 16. CO2 will therefore have a mass of 28 g/mol. Divide 22 by 28 to get about 0.79 moles. Convert C to Kelvin by adding 273; getting 323K. Then use the ideal gas law (PV=nRT) to solve for V (V=nRT/P). This gets you 21.32 L, hope this helps!
