An isotope is defined as an element that has the same number of protons as the common element but different number of neutrons. In this case, a beryllium atom has a molar weight of 10 amu. Thus, there are 4 protons and 6 neutrons. The nuclear symbol of Be-10 is 4 Be10

What is the concentration (in M) of a sample of the unknown dye with an absorbance of 0.25 at 542 nm?
Sladkaya [172]

Answer:

see explanation below

Explanation:

Question is incomplete, so in picture 1, you have a sample of this question with the missing data.

Now, in general terms, the absorbance of a substance can be calculated using the beer's law which is the following:

A = εlc

Where:

ε: molar absortivity

l: distance of the light in solution

c: concentration of solution

However, in this case, we have a plot line and a equation for this plot, so all we have to do is replace the given data into the equation and solve for x, which is the concentration.

the equation according to the plot is:

A = 15200c - 0.018

So solving for C for an absorbance of 0.25 is:

0.25 = 15200c - 0.018

0.25 + 0.018 = 15200c

0.268 = 15200c

c = 0.268/15200

c = 1.76x10⁻⁵ M

Through which conversion is energy released? adp to atp atp to adp nadp to nadph co2 and h2o to c6h12o6 and o2
aleksandrvk [35]
  • Energy transformation includes ATP and ADP. at the point when energy is delivered, the response will in general separate a bigger particle to a more modest structure.
  • For this situation, the bigger particle is ATP comprised of three phosphates bunches while ADP is just made out of two phosphate gatherings.
<h3>What is the energy source for the conversion of ADP and ATP?</h3>
  • The energy expected for the change of ADP into ATP is acquired from light during photosynthesis and from exothermic responses during cell breath in the two plants and creatures.
  • ADP is produced on hydrolysis of ATP and the energy released in the process is utilised to carry out various cellular processes.

Why does a solid have a definite shape and volume?
stellarik [79]

Answer:

B
