We know that the greater the difference is in
electronegativity between the atoms which holds the molecule, the greater the
polarity is the bonds between them. <span>
<span>Since we know that F has the highest electronegativity among
all the elements, therefore PF3 has more
polar bonds than PCl3. </span></span>

Percent by mass of platinum in white gold = 100% - 45% = 55%
We let x be the mass of the white which is 45% gold and 55% platinum.
Mass of gold in white gold = m x 0.45
where m is the total mass.
From the given above, we formulate the equation that would allow us to determine the mass of white gold.
154 = x (0.45)
x = 342.22 g
Then, we determine the amount of platinum.
mass of platinum = (342.22 g)(0.55)
mass of platinum = 188.22 grams
Thus, 188.22 grams of platinum is needed.
Answer:
A) A contains sugar and B contains salt, because salt is ionic and a good conductor of electricity.
Explanation:
Because sugar is not a good conductor of electricity
Answer:
A. task and social cohesion.
Explanation:
Cohesion comprises of both task cohesion and social cohesion.
Task Cohesion generally refers to the degree to which members of a work group come together to achieve common goals, example, to win a game or challenge.
Social Cohesion: reflects the degree to which members of a team like each other and interact accordingly.
