What would you predict about a chemical that has a hydrogen ion concentration of 1 x 10−12 M? (1 point) a
It will form salt and water when added to a base.

b
It contains no hydroxide ions.

c
It has high concentration of hydroxide ions.

d
It has a sour taste.

Could someone me find the answer to this problem.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
