In general, The more valence electrons a metal has, the stronger its metallic bonds will be because Boron is a metalloid and is ionically bonded.it is too electronegative to release its valence electrons for metallic bonding.As a result, their valence electrons feel a stronger pull from the nucleus (a greater effective nuclear charge) and are less easily released for metallic bonding.
Answer:
See explanation.
Explanation:
Hello there!
In this case, considering the given information, it is not possible to figure out such order of reaction with respect to water as it is not involved in the given chemical reaction:
2E(g)+ F(g)+O(g)_
However, we can say that the order of reaction is 2 with respect to E (power of 2 in the rate law), 1 with respect to F (power of 1 in the rate law) and 0 with respect to O (power of 0 or not present in the rate law).
Regards!
Answer:
- The main idea behind MADs is that they use the principle that metallic objects (submarines) interfere in the magnetic lines of Earth forces. And this equipment detects this anomaly.
- Submarines can be detected by using MADs
- The history of MAD development
In 1917 the interest in the detection of submarines started with the study hydrophones. Then in 1918, the U.S. considered to use the magnetism in this area but it did not result to be practical as it had a limited detection range.
Then by 1941 in Britain and in U.S. developed magnetic detection devices to measure Earth’s magnetic field, so after that in 1943 MADs were installed in ASW aircrafts.
Due to the limited range and its lack of ability to detect the magnetic variance from different sources, MAD started to be used in combination with sonobuoys. This combination allowed an aircraft to localize submarines with the confirmation of sonobuoys.
Explanation:
MADs are Magnetic Anomaly Detectors. Their function is to detect anomaly in the Earth’s magnetic field caused by submarines.
Submarines are made of ferrous metal which contain domains that are tiny magnets form of iron molecules. This material creates a disturbance that can be detected in the magnetic field.
When entering a science lab which of the following should be done by science students.
D. Students must wait for their teacher to give instructions.
6. 20.0 x 17.16= 343.2m^2
The most abundant isotope among the given Isotopes will be Isotope B
<h3>How to calculate percentage abundance of isotopes ?</h3>
To calculate the percent abundance of each isotope in a sample of an element, we usually divide the number of atoms of a particular isotope by the total number of atoms of all isotopes of that element and then multiply the result by 100.
% Abundance = 15/50 x 100
= 30 %
% Abundance = 30/50 x 100
= 60 %
% Abundance = 5/50 x 100
= 10 %
Hence, The most abundant isotope among the given Isotopes will be Isotope B.
