The best answer for this question would be B
Answer:
1.1
Explanation:
The slope of a line can be calculated using the values of the x and y corrdinates. The equation is given as;
M = ΔY / ΔX = Y2 - Y1 / X2 - X1
From the points;
(25.6cm³ , 28.16g) - (X1, Y1)
(17.3cm³, 19.03g) - (X2, Y2)
Inserting the values into the equation;
M = 19.03 - 28.16 / 17.3 - 25.6
M = -9.13 / -8.3 = 1.1
To determine the number of potassium laid side by side by a given distance, we simply divide the total distance to the diameter of each atom. The diameter is twice the radius of the atom. We calculate as follows:
number of atoms = 4770 / 231x10^-12 = 2.06x10^13 atoms
Answer:
108.81 K
Explanation:
First convert 17 °C to Kelvin:
Assuming ideal behaviour, we can solve this problem by using the<em> combined gas law</em>, which states that at constant composition:
Where in this case:
We <u>input the data</u>:
- 800 torr * 100 L * T₂ = 600 torr * 50 L * 290.16 K
And <u>solve for T₂</u>:
