The mass percent of iron in an iron ore can be determined by converting Fe to Fe2+ in acid solution, and then titrating the dissolved sample with KMnO4 solution. A 2.51 g ore sample dissolved in acid required 28.62 mL of 0.0821 M KMnO4 to react the equivalence point. Calculate the mass percent of iron in the ore. 8 H+(aq) + 5 Fe2+(aq) + MnO4-(aq) ----gt; 5 Fe3+ (aq) + Mn2+(aq) + 4 H2O(l) How would you solve this?
Cross rotate the front tires.left to right.etc. If the pull switces its a tire pull.ie 'Radial pull
Your car naturally pulls to the right. Its supposed to be a safety feature. For example if you fall asleep at the wheel it is supposed to drift you off the road, out of the way of traffic. But if it is pulling really hard you should check your tires for stripping or try balancing your tires. Also its never good to replace just one tire, so if you have to replace one, you might as well get the other. Hope that helps
As another answer stated the alignment should not have been done with bad tires. Try changing the rear tires to the front if they are good and see if this helps. Without me seeing the tires I can't tell you if they are bad or not. Uneven wear, broken belts or other tire problem could cause it to pull. Even low tire pressure in one tire can cause it. Tires on front should match in size, construction, tread design, and wear. Tires on rear should match also especially in size but front and rear do not have to match. If changing the tires fixes it you should get a new pair. Have them put on the front and right away your alignment should be checked. Whoever did the work owes you an alignment because they should know better. If you try to align the front end with bad tires you cannot be sure that it is done right. MUST have decent tires when getting an alignment!
is someone able to tell me what is the correct answer for this question?
