I attached a photo of my work below. Please tell me if I got it wrong; hope you got a good score on your assignment! ^v^
Answer:
1.7 bar
Explanation:
We can use the <em>Ideal Gas Law</em> to calculate the individual gas pressure.
pV = nRT Divide both sides by V
p = (nRT)/V
Data: n = 1.7 × 10⁶ mol
R = 0.083 14 bar·L·K⁻¹mol⁻¹
T = 22 °C
V = 2.5 × 10⁷ L
Calculations:
(a) <em>Change the temperature to kelvins
</em>
T = (22 + 273.15) K
= 295.15 K
(b) Calculate the pressure
p = (1.7 × 10⁶ × 0.083 14 × 295.15)/(2.5× 10⁷)
= 1.7 bar
Answer:
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Make sure to edit so you don't get copy-writed.
Answer:
The correct option is;
Placing one drop of food coloring in a cup with 60 ml of water at 10°, placing one drop of food coloring in a second cup with 60 ml of water at 40°C
Explanation:
The experimental setup that would allow the student investigate the connection between kinetic energy and temperature should be made up of the following characteristics
1) The constant terms for the experiment should be defined, which in this case are
a) The volume of the water which is 60 ml in both subjects of the experiment
2) The definition of the variable that produces the effect that is being monitored, which is the use of the different temperatures in the two experimental subjects
3)The environmental limits of the experiment, which is the water and the food coloring used
