Answer:
B. accepted value x 0.1
Explanation:
in the equation provided
Maximum allowed value of percentage error = 10%
put this value in the equation in stead of percentage error we get,
so maximum error = .1 x accepted value
10 % percentage error means the experimental value has 10 % error compared to accepted value.so error will be 10 % of the accepted value
or .1 times of accepted value
Answer:
Here boron-11 means the name of the element is boron and the mass number is 11
Explanation:
Answer:
a natural process is water cycle.
Explanation:
during this process,water evaporates from different water bodies ,when the warm water rises,the cold and heavier water comes down to take its place.On the other hand,the warm water on rising,changes to water vapour.
This water vapour helps in the formation of clouds .
When the cloud becomes heavy and is not able to hold the water vapour, it falls down as rain or snow depending upon the climate and atmospheric temperature.
This process continues over and over again
Key feature of a Bronsted Lowry base : The notable feature of all bronsted lowry bases is that they contain atleast one electron lone pair, which is available for interaction with a proton, and allows the base to act as a proton acceptor.
<h3>What do we know about Bronsted Lowry Base?</h3>
Any species that can receive a proton and needs one pair of electrons to attach to the H+ is referred to as a Bronsted-Lowry base. Since water is amphoteric, it may function as both a Brnsted-Lowry acid and a base.
The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.

Answer:
876 grams
Explanation:
Convert specific gravity to density, using water density 1.0 g/ml
d = e.g x 1.0 g/ml = 1.168 g/ml
d = m/v (mass/volume)
m = dxv = 1.168 g/ml x 750 ml = 876 grams
