oee [108]3 years ago
8 0

Answer:after 4 PCR cycles, 24 = 16 DNA

Explanation:From a single DNA template molecule, it is possible to generate 2n DNA molecules, after 'n' number of cycles in polymerase chain reaction (PCR). So, after 4 PCR cycles, 24 = 16 DNA molecules will be formed.

What is the coefficient of H2O when the following equation is properly balanced with the smallest set of whole numbers? ________
LiRa [457]

The given question is incomplete. The complete question is :

What is the coefficient of H_2O when the following equation is properly balanced with the smallest set of whole numbers? PCl_3(l)+H_2O(l)\rightarrow H_3PO_3(aq)+HCl(aq)

Answer: The coefficient of H_2O is 3

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

PCl_3(l)+3H_2O(l)\rightarrow H_3PO_3(aq)+3HCl(aq)

The coefficient of H_2O is 3

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.

1 Clouds are formed when millions of drops of water become suspended in the air. Which
ioda

Answer:

C Condensation of water vapor

Explanation:

One of the components of the atmosphere is water vapour. Water vapour is always present in air.

This water vapour may combine with particles of dust and smoke and condense around them to form clouds.

As more water vapour condenses and coalesces, the clouds become thicker and precipitation eventually follows.
