The one property that you can always depend on to change vapor pressure is temperature. So as the water's temperature increases so does the vapor pressure. The warmer the water, the higher the vapor pressure.

Blank one: Hot water

Blank Two: Temperature

Answer: The <em>hot water</em> puddle has the highest vapor pressure because vapor pressure depends on<em> temperature.</em>

Explanation:

Vapor pressure of the liquid is defined pressure exerted by the vapors of the liquid on its liquid surface. It increases with increase in temperature and vice-versa. And it also depends upon surface area of the liquid.

A medium puddle with hot water will have maximum vapor pressure because the hot water has higher temperature from the remaining other two puddles.

Qué clase de alimentos podemos encontrar que contengan oligoelementos como Cromo (Cr), Litio (Li), Selenio (Se), Manganeso (Mn),
Slav-nsk [51]

Answer: There are many foods who have trace elements like seafood, legume, vegetables, tomatoes, bananas, eggs, fishes, meat.

Their five mainly functions are accept or receive electrons in redox reactions, act like cathalytic centers which are necessaries to live, control biologics process like the hormon activation and gen expression, provide stability, 3d structures in important molecules.

Explanation: Trace elements participate in redox reactions because they have acid-base components which alkalize o acidify the way, protecting the organism from free radicals.

Biological sources which are controlled by trace elements are:

  • assimilation of ATP
  • methabolic sources relationed with insuline
  • oxygen transport in the organism
  • stomach acid formation
  • 3d structures from important moleculess are mantained by balance of electrons which make up the atoms from the molecule.

Silver was precipitated and collected by filtration. The experiment yielded .077g of silver after dying. The predicted yield was
PSYCHO15rus [73]

Answer:

Precentage error = 7.23%

Explanation:

The precentage error formula  is the  useful method  for determining precision of your experimental result

It can be calculated using :

percent\ error = |\frac{experimental\ value-predicted\ value} {predicted\ value}|\times 100

percent\ error = |\frac{0.077\ -0.083} {0.083}|\times 100

So we get percentage error =  7.23%

Precision means how close the experimental value to the true value or theoretical value

If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment

If the percentage error is zero it means the experiment is perfectly done without  inaccuracy
