Burning 1 kg of coal releases about 3 million joules of energy. If you could use all of the chemical energy to lift another kilo
Katarina [22]

I could lift 3.06 x 10⁵ m high

<h3>Further explanation </h3>

Energy is the ability to do work. Energy can change from one energy to another

Potential energy is the energy that an object has because of its position

The potential energy can be formulated:

Ep = m. g. h

E = potential energy of an object, joule

m = object mass, kg

g = gravity acceleration, m / s²

h = height of an object, m

energy of coal = 3.10⁶ J

mass = 1 kg

g = 9.8 m/s²

\tt h=\dfrac{E}{m.g}\\\\h=\dfrac{3.10^6}{1\times 9.8}=3.06\times 10^5`m

Number 51 is 0.00150 ml to l
xenn [34]

Answer:

The answer to your question is

51.- 1.59 x 10⁻⁶

53.- NaHCO₃ +  HCl  ⇒   H₂O  +  CO₂  +  NaCl

Explanation:

51.- Convert 0.00159 ml to liters

Use a rule of three

                                 1000 ml -------------- 1 l

                                 0.00159 ml ---------   x

                                 x = (0.00159 x 1) / 1000

                                 x = 0.00000159 l = 1.59 x 10⁻⁶ l

53.- Sodium hydrogen carbonate (NaHCO₃) reacts with hydrochloric acid to produce salt, water and carbon dioxide.

Sodium hydrogen carbonate = NaHCO₃

Hydrochloric acid = HCl

Reaction

                  NaHCO₃ +  HCl  ⇒   H₂O  +  CO₂  +  NaCl

water = H₂O

carbon dioxide = CO₂

salt = NaCl

How many moles of AgNO3 must react to form 0. 854 mol Ag? mol AgNO3.
babunello [35]

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

The balanced chemical equation for the dissolution of silver nitrate has been:

\rm AgNO_3\;\rightarrow\;Ag^+\;+\;NO_3^-

The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.

In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.

From, the balanced equation,

\rm 1\;mol\;AgNO_3=1\;mol\;Ag

The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:

\rm 1\;mol\;Ag^+=1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;\times\;1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;mol\;AgNO_3

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.
