An enzyme speeds up chemical reactions as it acts as a catalyst.
Answer:
The mass of material is 96.12 g
.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
density of material = 2.7 g/mL
volume= 35.6 mL
mass= ? (in g)
Now we will put the values in the formula,
d= m/v
m=d×v
m= 2.7 g/mL × 35.6 mL
m= 96.12 g
so, the mass of material is 96.12 g
.

hope this helps you..........
Since the speed of the bag is constant, it’s kinetic energy remains constant. Since it’s height above the ground is constant, it’s gravitational potential energy is also constant. Since it’s total energy is constant, net work = 0.
Answer: Two elements are liquid at standard temperature and pressure: mercury and bromine. All the other elements are solid under standard conditions, which means their freezing point is above 0 degrees Celsius. Hope this helps (:
