Explanation:

The problem deals with a phase transition from solid to liquid. To the left we have ice and to the right we have liquid water.

For such change to take place, the process of melting must occur. During melting, a solid changes state from solid to liquid by taking energy from the environment.

In solid state, the molecules of the water are in a fixed state about their fixed lattice.
As the solid ice gains energy from the environment, it begins to melt.
Energy increase causes the molecules of the water to start flowing to form a liquid.

Answer: Light

Computer is an example of light energy which is the third option out of the given four choices. 

Explanation:

We know how a computer works it takes in the electrical energy and does a lot of mathematical mechanical work and for giving answers. It uses a screen on which light blinks in pattern such that it represents letters or mathematical numbers or expressions.

Hence by using this statement we can say computer converts electrical energy into light energy.

When preparing for work in the fume hood, be sure to gather all necessary tools, glassware, and chemicals _________ to minimize

andreyandreev [35.5K]

Answer:

In advance

middle

lower

Explanation:

These are the safety precautions needed when carrying out duties in the fume hood.

When planning and preparing to work in a fume hood (a locally designed area to reduce exposure to hazardous fumes). It is advisable to make all equipment readily available at your disposal in advance to reduce and minimize the raising and lowering of the hood sash at intervals.

It is also pertinent to understand that working in the middle of the work surface helps to promote the movement of air and keeps the area neat and tidy.

However, if any case where there is a need to get a new tool or equipment during the process of working in a fume hood, it is advisable to lower the sash at that point in time.

What mass of agno3 can be dissolved in 250g of water at 20°c?

Mice21 [21]

Hello there,

You should know the solubility of AgNO3 in water at 20°C equals to 2220 g/L.

So we can say that in 1 L of water, 2220 g of AgNO3 can be dissolve.

Now you should know 1L = 1000g.

Which means 1000 g of water can dissolve 2220 g of AgNO3.

Therefore :

250 g --> x
1000 g --> 2220 g

So : $x = \frac{250*2220}{1000} = \frac{555000}{1000}= 555g$ .

In short, 555g of AgNO3 can be dissolved in 250g of water at 20°C.

Hope this helps !
