Convert 645 Newtons per quart to tons per liter. (The picture is a conversion table for help)
brilliants [131]

Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.

Consider the balanced chemical equation: 2o3(g) → 3o2(g). how many moles of o2 are produced when 0.50 mol of o3(g) reacts
kiruha [24]
   2O3→3O2
 The  number  of moles of O2  that  are   produced  when 0.50  moles  of O3(g)  reacted is  0.75  moles

  calculation and explanation

   2  moles    of O3(ozone)  react  to give   3 moles of O2  (oxygen  gas,therefore the reacting   ratio  between O3 :O2 is  2:3

 
 if 0.50  moles of  O3  reacted  then,by use  of  reacting ratio (2:3)  find the moles of O2  produced

That is   0.50 x3/2  =  0.75   moles

Write an equation for the neutralization of lemon juice with baking soda. Your equation should show a proton transfer to form ca
Jobisdone [24]

The equation of the neutralization reaction is:

HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O

<h3>What is the acid in lemon juice?</h3>

The main acid in lemon juice is citric acid.

Citric acid is a tricarboxylic acid and will react with baking soda to form a salt and water.

The equation of the neutralization reaction is shown below:

HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O

In conclusion, the neutralization of citric acid in lemon juice produces a salt and water.
