Answer: HOPE IT HELPS! PLS MARK AS BRAINLIEST
Explanation: The respiratory pigment, haemoglobin in red blood cells have a very high affinity of oxygen. It combines with oxygen to form oxyhaemoglobin and thus oxygen is carried from lungs to various body parts. Carbondioxide is highly soluble in water so it is mostly transported in dissolved form in our blood plasma.
I feel like it's C. or D. but I guess it's C.
If the burning of magnesium to form magnesium oxide is incomplete, there will still br some elemental magnesium available to be burned (ie combined with oxygen) and so there will be a measureable amount of mass of magnesium left. Also, the amount of oxygen required to combine with the outstanding mass of magnesium could also be determined.
Answer:
The correct answer is
B. I and II only
Explanation:
The limitations of robots in factory and research include
1. Robots are capital intensive and require high cost to maintain while still being maintained by humans
2. Robots develop fault and require specific procedures to rectify the fault hance there is high potential for delays in factory production work.
3. When there is a cause for alteration of process or change in operation, the robot most likely will have to be changed as well whike the humans implement the change
4. In research, robots can not recognize unexpected variation indications and synthesis of ideas to explain observed anomalies like humans.
5. A robot does not increase in knowledge of an subject they work on whichose valuable insight is vital to research
Answer:
Explanation:
In ion exchange softener , the minerals of hard water are in the form of ions of Mg⁺² and Ca⁺² . They are replaced by Na⁺ ion . The Na⁺ that resides on the bed of resin used in ion exchange softener make all heavy ions like Mg⁺² and Ca⁺² . In this way all the hard ions of hard water are removed and they are replaced by Na⁺ ion . hard ions are removed because they form insoluble compounds so they are precipitated out.
The ion that remains in soft water is Na⁺ ion.
The negative aspect of consuming this ion is that it is harmful for those suffering from heart ailment like heart pressure.
