Answer:
<u>d. a row of elements</u>
Explanation:
Elements that are in the same group, have same number of electrons and make up a column in a periodic table.
Answer: 107.3 ml
Explanation:
(843.6g)/(7.86 g/ml) = 107.3 ml
1. Q = 112.8 kJ
2. Q = 5.01 kJ
<h3>Further explanation</h3>
The heat to change the phase can be formulated :
Q = mLf (melting/freezing)
Q = mLv (vaporization/condensation)
Lf=latent heat of fusion
Lv=latent heat of vaporization
1. m=50 g=0.05 kg
Lv for water = 2256 kJ/kg
2. m=15 g=0.015 kg
Lf for water = 334 kj/kg
All you need to now is that 1L = 1000
so
Mass of 3.00L of pure water = 3000
*1.03g/
=
3090gMass of 3.00L of whole blood = 3000
*1.05g/
=
3150gMass of 3.00L of seawater = 3000
*1.00g/
=
3000g
