Answer:
Potassium dicyanoargentate(I) | C2AgKN2 - PubChem.
Synonyms: Potassium dicyanoargentate(I)pota...
Molecular Formula: C2AgKN2
Explanation:
An isotope is a chemical structure that is highly similar to its parent isotope, with the difference lying in the number of neutrons that the compound has. As an example, carbon has the elemental number 6, which means it has 6 protons. 12-carbon will have 6 protons and 6 neutrons, while 14-carbon will have 6 protons and 8 neutrons. The differing neutron numbers will have an affect on the nuclear reactions between these two compounds, but their chemical reactions will remain the same as the neutrons will not affect how they perform on a chemical level.
First thing, you convert from kPa to Pa. Then, you find the atm value of the Pa you got.
155 kPa = 155 000 Pa
1 atm = 101 325 Pa
x atm = 155 000 Pa
You divide 101 325 over 155 000 and you get about 1.53
So, 155 000 Pa = 1.53 atm.
So, T (temperature) = 25 + 273 = 298
605 kPa = 605 000 Pa
1 atm = 101 325 Pa
x atm = 605 000 Pa
You divide 605 000 over 101 325 and you get about 5.97
So 605 000 Pa = 5.97 atm
So, T = 125 + 273 = 398
P1 * V1/T1 = P2 * V2/T2
1.53 * 1/298 = 5.97 * V2/398
You calculate ad you get V2 = 0.342 L
Hope this Helps :)
Answer:
0.3936 J/gC
Explanation:
using the formula: q=mcΔt
q= 7032J
m=812g
ΔT = 22C
plug in and solve:
7032=(812)(c)(22)
c=7032/(812)(22)
c=0.39 J/gC
Oxygen is the 2nd most electronegative element. When you examine a periodic table, you will find that (excluding the noble gases) the electronegativity values tend to increase as you go to the right and up. The reverse statement is that the values tend to decrease going down and to the left.
