Answer:
Cell Membrane
The thin, flexible outer covering of a cell. It controls what enters and leaves a cell.
Explanation:
Given:
128g sample of titanium
2808J of heat energy
specific heat of titanium is 0.523 J/ g °C.
Required:
Change in temperature
Solution:
This can be solved
through the equation H = mCpT
where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
Plugging in the
values into the equation
H = mCpT
2808J = (128g) (0.523
J /g °C) T
T
= 41.9 °C
Answer:
i)
1 is Argon
2 is Kalium
3 is Calcium
ii)
Y belongs to alkaline metals
Z belongs to alkaline earth metals
iii)
Kalium (Y) is alkaline metal
Phospholipids and embedded proteins make up the cell membrane.
