Answer: It is reactive
Explanation:
Platinum is the least reactive element on the reactive scale.
For example, the platinum doesn't give the reaction with the oxygen that is found in the air, even though if it is heated but platinum does show the reaction with fluorine, chlorine and at red heat. Platinum can be found in a pure form in nature.
Platinum is reactive, it can react with some elements, but it is the least reactive element and also it is called unreactive, it doesn't easily react with elements.
Answer:
1.1 x 10⁴ J
Explanation:
To calculate eth energy needed, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy/heat (J)
-----> m = mass (g)
-----> c = specific heat (4.184 J/g°C)
-----> ΔT = change in temperature (°C)
You can plug the given values into the equation and solve.
Q = mcΔT
Q = (75.0 g)(4.184 J/g°C)(55.0 °C - 20.0 °C)
Q = (75.0 g)(4.184 J/g°C)(35.0)
Q = 11,000 J
Q = 1.1 x 10⁴ J
Answer: negatively charged; positively charged electrode.
Explanation:
Electrophoresis can de defined as the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The electrophoresis of negatively charged particles is called anaphoresis while the electrophoresis of positively charged particles is called cataphoresis.
During proten electrophoresis, due to electric field, proteins migrate through pores in a polyacrylamide gel matrix. It must be noted that pore size decreases with increasing acrylamide concentration.
Proteins set up at a buffer pH of 8.6, the proteins will become negatively charged (that is, anions) and it will move to the positively charged electrode.
Answer: 233 L of will be produced from 150 grams of
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 8 moles of
Thus 2.59 moles of will produce= of
Volume of
Thus 233 L of will be produced from 150 grams of
