You just calculated that the heat of fusion for chloromethane is 6400 J/mol. The heat of fusion for hydrogen is 120 J/mol. Which
makkiz [27]

Answer:

Chloromethane experiences dipole-dipole interactions.

Chloromethane has a higher molar mass than hydrogen.

Explanation:

The molar mass is directly proportional to the heat of fusion, since the heavier the molecules the more energy they need to separate. Intermolecular forces are also directly proportional to the heat of fusion, because the greater the interaction they experience, the more energy they require to separate. The dipole-dipole interactions experienced by chloromethane are stronger than the interactions that take place in hydrogen.

If a vector A has components A. 0, and Ay -0, then the magnitude of the vector is negative. Select one: True False
Dima020 [189]

Answer:

False

Explanation:

The magnitude of any vector is given by,

||A||=\sqrt{A_x^2+A_y^2}

The magnitude of anything is never negative. It can be even seen from the formula that the components are squared. A squared value can never be negative. Even if the component is negative the square will be always positive.

So, magnitude of the vector is <u>not</u> negative.

In a carnival booth, you can win a stuffed giraffe if you toss a quarter into a small dish. the dish is on a shelf above the poi
Georgia [21]

components of the speed of the coin is given as

v_x = v cos60

v_x = 6.4 cos60 = 3.2 m/s

v_y = vsin60

v_y = 6.4 sin60 = 5.54 m/s

now the time taken by the coin to reach the plate is given by

t = \frac{\delta x}{v_x}

t = \frac{2.1}{3.2}

t = 0.656 s

now in order to find the height

h = vy * t + \frac{1}{2} at^2

h = 5.54 * 0.656 - \frac{1}{2}*9.8*(0.656)^2

h = 1.52 m

so it is placed at 1.52 m height
