Answer:
B-Sucrose molecules are too large to conduct electricity in once dissolved in water.
D-Salts, like NaCL, have ionic bonds and are considered to be electrolytes:when dissolved in water, salts dissociate and form ions.
Explanation:
Hi Jojo
The 4 factors that makes a good fuel are
1) It should be cheap
2)It should not burn too fast or too slowly
3) It should be easily available

Answer:
C. A linear, nonpolar molecule
Explanation:
Molecules which are alike usually have the same degree of pull which results in them sharing electrons. This sharing of electrons is known as the molecules exhibiting Covalent bonding between them.
The equal pull also results in the cancelling out of electrons and favoring non polar bonds due to the absence of free electrons which would have been able to interact with H2O in a polar binding system.
=
= 0.134 mol
mol of oxygen:
ratio of
= 2 : 15
= 1 : 7.5
: . mol of
= 0.134mol * 7.5
= 1.01 mol
Mass of Oxygen = mol * Mr
= 1.01 mol * (16*2) g/mol
= 32.22g
Note: Mr is molar mass
<span>It is true that energy efficient dishwasher is a water
and energy saver than washing dishes by hand. A star-rated dishwasher uses 4
gallons of water in each cycle compare to a kitchen faucets who pumps out 2.5
gallons of water per minute. To conserve water, the accumulated dishes and cookware
must be stack properly in a dishwasher before running a cycle. As to conservation
of energy, people tend to use warm water to wash the dishes by hand and heating
of water cost much, while in a dishwasher, energy-saving tips such as running a
light cycle and turning off heating drying option will mark down your energy
consumption. Therefore, the use of dishwasher is a much greener idea. </span>
