<u>Answer:</u> The total number of moles of gases produced are 7.25 moles.

<u>Explanation:</u>

The chemical reaction for the decomposition of C_3H_5(NO_3)_3 follows the equation:

4C_3H_5(NO_3)_3\rightarrow 12CO_2(g)+6N_2(g)+10H_2O(g)+O_2(g)

We are given:

Moles of C_3H_5(NO_3)_3 = 1.00 mol

  • <u>For carbon dioxide:</u>

By Stoichiometry of the reaction:

4 moles of C_3H_5(NO_3)_3 is producing 12 moles of carbon dioxide.

So, 1 mole of C_3H_5(NO_3)_3 will produce = \frac{12}{4}\times 1=3mol of carbon dioxide.

Moles of carbon dioxide produced = 3 moles

  • <u>For nitrogen:</u>

By Stoichiometry of the reaction:

4 moles of C_3H_5(NO_3)_3 is producing 6 moles of nitrogen.

So, 1 mole of C_3H_5(NO_3)_3 will produce = \frac{6}{4}\times 1=1.5mol of nitrogen.

Moles of nitrogen produced = 1.5 moles

  • <u>For water:</u>

By Stoichiometry of the reaction:

4 moles of C_3H_5(NO_3)_3 is producing 10 moles of water.

So, 1 mole of C_3H_5(NO_3)_3 will produce = \frac{12}{10}\times 1=2.5mol of water.

Moles of water produced = 2.5 moles

  • <u>For oxygen:</u>

By Stoichiometry of the reaction:

4 moles of C_3H_5(NO_3)_3 is producing 1 moles of oxygen.

So, 1 mole of C_3H_5(NO_3)_3 will produce = \frac{1}{4}\times 1=0.25mol of oxygen.

Moles of oxygen produced = 0.25 moles

Total number of moles of the gases produced are = 3 + 1.5 + 2.5 + 0.25 = 7.25 moles.

Hence, the total number of moles of gases produced are 7.25 moles.

Suppose that the space shuttle Columbia accelerates at 14.0 m/s2 for 8.50 minutes after takeoff.
givi [52]

Answer:

A. speed = 7.14 Km/s

B. distance = 1820.7 Km

Explanation:

Given that: a = 14.0 m/s^{2}, t = 8.50 minutes.

But,

t = 8.50 = 8.50 x 60

  = 510 seconds

A. By applying the first equation of motion, the speed of the shuttle at the end of 8.50 minutes can be determined by;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.

u = 0

So that,

v = 14 x 510

 = 7140 m/s

The speed of the shuttle at the end of 8.50 minute is 7.14 Km/s.

B. the distance traveled can be determined by applying second equation of motion.

s = ut + \frac{1}{2}at^{2}

where: s is the distance, u is the initial velocity, a is the acceleration and t is the time.

u = 0

s = \frac{1}{2}at^{2}

  = \frac{1}{2} x 14 x (510)^{2}

 = 7 x 260100

 = 1820700 m

The distance that the shuttle has traveled during the given time is  1820.7 Km.

A 3.3 kg ball sits on the ground and is kicked with a FAPP of 36N
jeyben [28]

a) 32.3 N

The force of gravity (also called weight) on an object is given by

W = mg

where

m is the mass of the object

g is the acceleration of gravity

For the ball in the problem,

m = 3.3 kg

g = 9.8 m/s^2

Substituting, we find the force of gravity on the ball:

W=(3.3)(9.8)=32.3 N

b) 48.3 N

The force applied

F_{app} = 36 N

The ball is kicked with this force, so we can assume that the kick is horizontal.

This means that the applied force and the weight are perpendicular to each other. Therefore, we can find the net force by using Pythagorean's theorem:

F=\sqrt{W^2+F_{app}^2}

And substituting

W = 32.3 N

Fapp = 36 N

We find

F=\sqrt{32.3^2+36^2}=48.3 N

c) 14.6 m/s^2

The ball's acceleration can be found by using Newton's second law, which states that

F = ma

where

F is the net force on an object

m is its mass

a is its acceleration

For the ball in this problem,

m = 3.3 kg

F = 48.3 N

Solving the equation for a, we find

a=\frac{F}{m}=\frac{48.3}{3.3}=14.6 m/s^2

A carpenter lifts a 10-kg piece of wood to his shoulder 1.5 m above the ground. He then sets the wood on his truck at 1.0 m abov
FinnZ [79.3K]

Answer:

<em>500Joules</em>

Explanation:

Kinetic energy = 1/2mv²

m is the mass of the wood

v is the velocity

Given

Mass = 10kg

Velocity v = 10m/s

Substitute into the formula and get KE

KE = 1/2 * 10 * 10²

KE  = 1/2 * 1000

KE = 500Joules

<em>Hence the kinetic energy of the wood during delivery is 500Joules</em>
