Suppose you have 1000 lb of waste copper (II) oxide sitting in the basement of your factory. Do you see a problem with sending i

Free_Kalibri [48]

Answer:

Yes.

Explanation:

Yes, we have a problem with sending it to a landfill of copper oxide because it has harmful effect on the health of humans as well as more weight of the copper oxide. Copper oxide usually found in powder form which can easily be inhaled that causes death of the cell due to toxic effect on the mitochondria and lysosomes of the cell. It makes problem of health in carrying the copper oxide from the basement of the factory to the landfill region due to its power form so we can say that it can do problems to human health while carrying from one place to another.

A train that is accelerating at 5m/s² down the tracks and crashes into a car. If the train weighs 20,000kg, how much force does

iragen [17]

Answer:

100,000 N

Explanation:

Force, F = mass, m × acceleration, a

⇒F = ma

m= 20, 000kg

a = 5m/s²

∴ F = 5 × 20,000 = 100,000N

50g nitrous oxide combines with 50g oxygen form dinitrogen tetroxide according to the balanced equation below.

photoshop1234 [79]

Limiting reactant : O₂

Mass of N₂O₄ produced = 95.83 g

<h3>Further explanation</h3>

Given

50g nitrous oxide

50g oxygen

Reaction

2N20 + 302 - 2N204

Required

Limiting reactant

mass of N204 produced

Solution

mol N₂O :

$\tt =\dfrac{50}{44}=1.136$

mol O₂ :

$\tt =\dfrac{50}{32}=1.5625$

2N₂O+3O₂⇒ 2N₂O₄

ICE method

1.136 1.5625

1.0416 1.5625 1.0416

0.0944 0 1.0416

Limiting reactant : Oxygen-O₂

Mass N₂O₄(MW=92 g/mol) :

$\tt =mol\times MW=1.0416\times 92=95.83~g$

Calculate sound speed in hydrogen H2 at temperture 50 C degree. Answer give in meter per second.

irina [24]

Answer:

The speed of sound in hydrogen gas is 361.5 $^{\circ} C$

Explanation:

It is given that the temperature is 50 $^{\circ} C$ .

The speed of sound in meter per second is calculated by an equation.

The equation states that speed of the sound in meter per second is equal to the sum of the product of the temperature in degree celsius with 0.60 and a constant that is 331.5.

The equation is written as:

$speed \ of \ sound \left(m/s \right) = 0.60 \times T + 331.5$

Put the value of T = 50 then the equation becomes,

$speed \ of \ sound \left(m/s \right) = 0.60 \times 50 + 331.5$

Speed of sound (in m/s) = 361.5 m/s
