A student was provided with a solid sample made up of a mixture of components. Prior to separation, the student measured 2.895 g

Shtirlitz [24]

Answer:

Component 1, since it has the greatest mass.

Explanation:

Hello,

In this case, considering that the by-mass percent of a substance is computed:

$\% m/m_i=\frac{m_i}{m_{mixture}}*100\%$

In such a way, given the form of the equation one could infer that the higher the mass of the i component, the higher its by-mass percent, it means that the component with the greatest mass will have the highest by-mass percent for the mixture. In such a way, since the component 1 was found to have a mass of 1.12 g, it will have the highest by-mass percent.

Best regards.

What is the solubility of KI at 10C?

Bingel [31]

31.2g per 100g of water.

Explanation:

The required result about the solubility of KI at 10C is measured to be 31.2g per 100g of water.
Every solution contains a volume and that gets changed radically when the dissolution comes into existence. The result can be seen by inspecting the solubility in mol⋅L−1.
If we look closely to understand the solubility of KI, either at 10C or at any other temperature, you can ease it by a trick. The solubility of potassium bromide is approx twice its value.

Which lewis electron-dot diagram represents a nitrogen atom in the ground state

marin [14]

To do this, you 1st figure out the atomic number of which ever element you are working on. In this case, it's Nitrogen. Nitrogen has an atomic number of 7. So basically, you right N with 2 dots on top of it, 2 dots to the right, 2 dots below N and 1 dot to the left of N.
