Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
Answer:
Physical Change
Explanation:
Because the filter is removeing the dust by having the air go though a thin material.

V = 3.00 x 3.00 x 3.00 => 27 cm³
D = m / V
8.90 = m / 27
m = 8.90 x 27
m = 240.3 g
Answer:
it is a because blood is pumped but heart so the answer is A
Answer:
Final temperature = 28.0 degrees C.
Explanation:
heat absorbed = mass * specific heat * rise in temperature.
The specific heat of water is 4.186 J /g/C so we have the equation
209 = 10 * 4.186 * x where x is the temperature increase
41.86x = 209
= 5 degrees C.
