Answer:

C. The reaction is energetically favorable.

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

ATP+H_2O\rightarrow ADP+P_i+\ energy

The Gibbs' free energy change of this reaction, \Delta G^0=-7.3\ kcal/mol

Hence, Option A is not correct.

It is a type of hydrolysis reaction in which water is being added to the molecule.

Hence, Option B is not correct.

The Gibbs' free energy change is negative which means that the reaction is energetically favorable.

Option C is correct.

Why are scientists worried that climate change will cause these toxic algae blooms to become more frequent?
ipn [44]

Answer: Eutrophication is the enhancement of the growth of algae in the water body.

Explanation:

The scientists are worried for the climate change as if the climate changed to prolonged rainy then the frequent raining can remove toxic chemicals from the agricultural sites, landfills, industries, and from other locations and deposit them to the water body (river, lakes, ponds, and others). The deposition of the salts of nitrogen, phosphorus, and sulfur promotes the growth of algae in the water body. This leads to reduction in the concentration of oxygen in the water body. This is called eutrophication. The lack of oxygen can lead to mortality of aquatic animals.

A newly discovered element, Z, has two naturally occurring isotopes. 90.3 percent of the sample is an isotope with a mass of 267
blsea [12.9K]
atomic mass=percentage of isotope a * mass of  isotope a + percentage of isotope b * mass of  isotope b+...+percentage of isotope n * mass of isotope n.

Data:
mass of isotope₁=267.8 u
percentage of isotope₁=90.3%

mass of isotope₂=270.9 u
percentage of isotope₂=9.7%

Therefore:

atomic mass=(0.903)(267.8 u)+(0.097)(270.9 u)=
=241.8234 u + 26.2773 u≈268.1 u

Answer: the mass atomic of this element would be 268.1 u
