Answer:
1) Acids have a sour taste.
Acid formulas start with "H", contain hydrogen and some react with active metals in a single replacement reaction to give off hydrogen gas.
An acid will turn blue litmus paper red
All acids are SOLUBLE in water.
Acids have a pH below 7.
2) Bases are bitter to taste a bitter taste is characteristic of all bases.
trong bases are very corrosive and can burn the skin.
Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis
They can conduct electricity.
Bases lose their basicity when mixed with acids.
3) i dont know how to do it on here sorry but its self explanitory!!
4) 0-3 strongly
4-6 weakly
7 neutral
8-10 weakly
11-14 strongly

Explanation:
Velocity is a derived quantity, which is derived from two fundamental quantities ilength ( displacement ) and time
it can be depicted as :
The force on the box is:
F = mgsin∅
If we multiply by this with the distance it traveled, we will know the work done by the box.
W = dmgsin∅
This work will be converted to elastic potential energy in the spring which is:
1/2 kx². Equating these and substituting values:
1/2 * 170 * x² = 4 * 13 * 9.81 * sin(30)
x = 1.73 m
The box's maximum speed will at the point right before contact with the spring, when the compression is 0.
Answer:
D.Conduction, because the metal wire was in direct contact with water in both containers
An insulator is a material that does not allow a transfer of electricity or energy. Materials that are poor thermal conductors can also be described as being good thermal insulators.
