Answer:

The direction will be changed .

Explanation:

According to the principles of motion, if an object is moving with solitary velocity and if an external force is applied to it, then that force changes the position, speed, and direction of that object.

In the given question, an external force is being applied to the toy which will change the direction of that toy.

The composition (in mole percent) of the atmosphere is 78.1% N2, 21.0% O2, and 0.9% Ar. What is the partial pressure of each gas

Luda [366]

Answer:

N2 = 588.95 mm Hg

O2 = 158.36 mm Hg

Ar = 6.787 mm Hg

Explanation:

Their percentage represents their mole fraction.

N2= 78.1% = 0.781

O2 = 21.0% = 0.21

Ar = 0.9% = 0.009

Barometric pressure is 754.1 mm Hg

Partial pressure for each will be,

For N2 = 0.781 x 754.1 = 588.95 mm Hg

For O2 = 0.21 x 754.1 = 158.36 mm Hg

For Ar = 0.009 x 754.1 = 6.787 mm Hg

Answer:

from the pic:

$empirical \: formular : \: \: C _{2}H _{3}O _{2}$

since molar mass is 118.084 g/mol;

$(C _{2}H _{3}O _{2}) _{n} = 118.084 \\ C _{2n}H _{3n}O _{2n} = 118.084 \\(12 \times 2) _{n} + (1 \times 3) _{n} + (16 \times2 ) _{n} = 118.084 \\ 24_{n} + 3_{n} + 32_{n} = 118.084 \\ 59_{n} = 118.084 \\ n = 2$
