Based on the effect of temperature on a reaction, a change in temperature affects the rate constant K.

Based on the Arrhenius equation, the y-intercept gives the value of ln A.

From the value of the slope, the value of Ea is 42.1 J/mol.

<h3>What is the effect of temperature on a reaction?</h3>

A change in the temperature of a reaction acts to increase the rate of reaction.

  • Change in temperature has no effect on the ideal gas constant.
  • Change in temperature has no effect on the activation energy.
  • Change in temperature has no effect on the concentration of reactants.
  • Change is temperature can either lower or increase the rate constant of a reaction.
  • Change in temperature has no effect on the order of reaction.

According to the Arrhenius equation, the y-intercept gives the value of ln A.

From the graph; slope = -Ea/R

Ea = -slope/R

Where;

  • Ea is activation energy
  • R is molar gas constant = 8.314 J/K.mol
  • Slope = -350 K

Ea = -(-350)/8.314

Ea = 42.1 J/mol

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
zloy xaker [14]

Answer:

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the <u>phosphate</u> group attached to the 5' carbon atom of the sugar portion of a nucleotide and the <u>hydroxyl</u> group attached to the <u>3'</u> carbon atom

Explanation:

Nucleic acids are polymers formed by a phosphate group, a sugar (ribose in RNA and deoxyribose in DNA) and a nitrogenous base. In the chain, the phosphate groups are linked to the 5'-carbon and 3'-carbon of the ribose (or deoxyribose) and the nitrogenous base is linked to the 2-carbon. Based on this structure, the nucleic acid chain orientation is identified as the 5'-end (the free phosphate group linked to 5'-carbon of the sugar) and the 3'-end (the free hydroxyl group in the sugar in 3' position).

Copper metal reacts with hot concentrated sulfuric acid solution to form aqueous copper(ii) sulfate, sulfur dioxide gas, and wat
Alex777 [14]
The unbalanced chemical equation with the corresponding phase for each substance is shown below: 

Cu₍s₎ + H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + H₂O₍l₎

The copper metal is solid, the sulfuric acid and copper sulfate are in aqueous solution. Water is in the liquid phase while sulfur dioxide is in the gas phase. 

In order to obtain the balanced equation, we must ensure that the number of atoms present in the reactant side is equal to that in the product side. First, we list the elements involved and count their number on each side.

Reactant           Product
   1             Cu      1
   2              H       2
   1              S       2
   4              O       5

To balance the equation, we need to have 2 moles of H₂SO₄ and 2 moles of H₂O. The balanced chemical equation is then:

Cu₍s₎ + 2H₂SO₄₍aq₎ → CuSO₄₍aq₎ + SO₂₍g₎ + 2H₂O₍l₎

Reactant           Product
   1             Cu      1
   4              H       4
   2              S       2
   8              O       8

To convert from liters/second to cubic gallons/minute, multiply the number of liters/second by 15.850 0 0.0353 00.2642 0 60
ivanzaharov [21]

Answer: 15.850

Explanation:

The conversion used from liters to gallons is:

1 L = 0.264172 gallon

The conversion used from sec to min is:

60 sec = 1 min

1 sec =\frac{1}{60}\times 1=0.017min

We are asked: liters/sec = gallons/min

liters/sec=\frac{0.264172}{0.017}=15.850gallons/min

Therefore, to convert from liters/second to gallons/minute, multiply the number of liters/second by 15.850.
