Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

I’m not very sure but I think it’s an atom of gold or if it isn’t, it could be heat from the sun
Answer:
The correct answer is B. An atoll is a coral island formed on top of a volcano, and a lagoon is the water enclosed within it.
Explanation:
Yeah!! As it acts in slightly acidic medium i.e., of pH 6.8 so, acidic conditions deactivate amylase enzyme...
