Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
Answer:
Gold
Explanation:
Platinum has an atomic number of 78.
78 + 1 = 79
The element with atomic number 79 is Gold.

The Standard Temperature and Pressure is 1 atm, 273 K
<u>Explanation:</u>
STP is Standard Temperature and Pressure
- Standard temperature is characterized as zero degrees Celsius (0°C), or 273.15 degrees Kelvin (273.15 K). This is the point of solidification of water at sea level, in the air at standard pressure.
Standard Temperature is
0° C in Celsius or 273 K in Kelvin
- Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr. STP is the "standard" condition regularly utilized for estimating gas density and volume.
Standard Pressure is
1 Atmosphere (atm)
760 Torricelli's (torr)
760 Millimeters of Mercury (mmHg)
101.325 KiloPascals (kPa)
1. I think it is true?
2. Low melting points
3. True
4. Atomic number, I think it’s periods?
5. Groups?
Sorry, I might not get all of them right :(
Hope this helps you in any way!!
I think it’s called condensation or water vapor
