Hey there!:
Mass = ?
Volume = 35.5 mL
density = 3.6 g/mL
By the definition of density :
D = m / V
3.6 = m / 35.5
m = 3.6 * 35.5
m = 127.8 g
hope this helps!
Answer:
A
Explanation:
When molecules speed up, they become excited and create friction that is transformed into heat, do when an abject cools, the molecules slow down and thus for have less friction.
Answer:
Yesssssss , option two is the correct one click it buddy
Explanation:
You answer this by using the pH formula and and the relation of pH and pOH, pH = -log[H+] and 14 = pH + pOH. The correct classification are as follows:
<span>A. [H2O+]=6.0x10^-12
basic
B. [H3O+]=1.4x10^-9
basic
C. [OH-]=5.0x10^-12
acidic
D. {OH-]=3.5x10^-10
acidic
Hope this answers the question.
</span>
Your answer would be an Arrhenius base
Hope this helps
