This problems requires the use of the density given. By using dimensional analysis, you convert 1.00kg into grams then you divide the resulting grams by the density. Then reduce to 3 significant figures and your answer is 924mL of acetic anhydride.

A gas occupies a volume of 30.0L, a temperature of 25°C and a pressure of 0.600atm. What will be the volume of the gas at STP?​
Shalnov [3]

Answer:

=16.49 L

Explanation:

Using the equation

P1= 0.6atm V1= 30L, T1= 25+273= 298K, P2= 1atm, V2=? T2= 273

P1V1/T1= P2V2/T2

0.6×30/298= 1×V2/273

V2=16.49L

Please help with this, i don't really get how to do this
LuckyWell [14K]
#4 and #5:
To find pH given concentration of H+ or H30+
pH = - log (H+ or H30+ M)

To find pH given concentration of OH-
Since you already found the pH for this (in #4), you subtract #4's answer from 14.
14 - (pH) = pOH

How do the properties of elements in the same column of the periodic table compare
Alik [6]
The columns of the periodic table, also referred to as "groups" contain elements with similar reactive properties, due to these elements having a similar configuration of electrons in their outer shell.

Which atom or ion is the largest?<br><br> A. K<br> B. K+<br> C. Ca<br> D. Ca2+<br> E. Li
pishuonlain [190]

Answer:

A. K

Step-by-step explanation:

Remember the trends in the Periodic Table:

  • Atomic radii <em>decrease</em> from left to right across a Period.
  • Atomic radii <em>increase</em> from top to bottom in a Group.
  • Ionic radii of metal cations are <em>smaller</em> than those of their atoms.

Thus, the largest atoms are in the lower left corner of the Periodic Table.

The diagram below shows that K is closest to the lower left, so it is the largest atom. It is also larger than any of the cations.
