Calculating  the  number  of  mole  of  COSO4  reacted 
=mass/R.F.M
R.F.M  of CUSO4  is  63.54+32+64=159.6
moles is  therefore 200g/159.54=1.254moles
 since  reacting  ratio  is  1:1 ,moles  of  Cu is  also  1.254moles
mass  is  therefore  moles x R.F.M
 1.254x63.54=79.6g(answer  C)

The energy diagram shows the changes in energy during a chemical reaction.
Brums [2.3K]

There is no diagram attached but there are some ways by which you can find it too easily by yourself

Usually energy diagram uses ∆H .

So

  • If ∆H is +ve means reaction is exothermic and energy is released
  • If ∆H is -ve means reaction is endothermic and energy is absorbed

So observe∆H whether it. is decreasing or increasing ,

  • If increasing then energy is being released and vice versa

Iodine chloride, ICl, can be made by the following reaction between iodine, I2, potassium iodate, KIO3, and hydrochloric acid.
Vadim26 [7]
The balanced chemical reaction is:

<span>2 I2 + KIO3 + 6 HCl ---------> 5 ICl + KCl + 3 H2O 
</span>
We are given the amount of the product to be produced from the reaction. This will be the starting point of our calculations.

28.6 g ICl (1 mol / 162.35 g ICl ) ( 2 mol I2 / 5 mol ICl ) ( 253.81 g I2 / 1 mol I2 ) = 17.88 g I2

I need help fast please <br> What is ATP?
Jobisdone [24]

Answer:

Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. Wikipedia

A sealed 5.00L flask contains an unknown gas at 1.05 atm and 296 K. How many moles of the unknown gas are in the flask?
xeze [42]

Moles of the unknown gas in the flask : 0.216

<h3>Further explanation</h3>

The gas equation can be written  

\large {\boxed {\bold {PV = nRT}}}

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

V=5 L

P = 1.05 atm

T = 296 K

\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.05\times 5}{0.082\times 296}\\\\n=0.216
