It's an acid-base type of redox reaction, in which neutralization occurs between the acid component [H+] of HCl and the base component [OH-] of NaOH. Equal parts of acid + base form H2O and the metal and halide combine to form neutral salt (NaCl).
Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is
Thus 
is given by
Answer:
His speed, in metres per second, is approximately 10m/s. The correct option is B.
Explanation:
Speed is defined as the rate in which an object cover a distance in a given time. It is measured in meters per second ( m/s). From the question, the jogger covered a distance of 3Km which when converted to meter is 3000meters in a given time 5 minutes which is 300seconds. The calculation of his speed in meter per second is shown below:
Distance= 3Km to meters ( as 1000meters = 1Km). Therefore 3× 1000 = 3000m
Time= 5 minutes to seconds ( as 1 minute = 60 Seconds). Therefore 5× 60= 300.
Speed= distance/ time
= 3000/300
= 10m/s
Therefore his speed, in metres per second, is approximately 10.
This answer is the same for all elements, a single atom of any element is still that element.
