When steam from a pan of boiling water reaches a cool window, it condenses. How much

Chemistry

Because the air right above your hot pan of water is so warm, the water vapor can be quickly absorbed there. When the heat is removed, the hot convective up current from the pan vanishes and is replaced with cooler air that can no longer contain as much moisture, which makes the condensing water vapour visible.

First, it's important to discuss the "steam" that is produced by the hot water. While we refer to it as steam, it is not. Water that is heated above 100 degrees Celsius produces steam. The only area in the kitchen where you can see it clearly is if you look very closely at the spout of a boiling kettle. The first 5mm (1/4") of the liquid will be clear when it is boiling very near to the spout.

<em>Answer:</em>

  • At 60 centigrade, the kinetic energy of the substance will be greatest.

<em>Explanation:</em>

As we know, the kinetic energy of substance is directly proportional to Temperature.

The total Kinetic energy can be calculated as follow

                                                K.E = 3/2 n.R.T

From the equations, it is cleared that Temperature is directly proportional to temperature.

If 40.0 g of HCl react with an excess of magnesium metal, what is the theoretical yield of hydrogen?
Alekssandra [29.7K]

<span>1.    </span>The balanced reaction is:<span>

Mg (s) + 2HCl (aq) --> MgCl 2 (aq) + H 2 (g) 

We are given the amount hydrochloric acid to be used for the reaction. This will be the starting point of the calculation.

40.0 g HCl ( 1 mol HCl / 36.46 g HCl) (1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>

A 2.0 mL sample of a liquid has a mass of 44.0 g. What is the density of the liquid?
riadik2000 [5.3K]

Answer:

The answer is

<h2>22 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}

From the question

mass of liquid = 44 g

volume = 2 mL

The density of the liquid is

density =  \frac{44}{2}

We have the final answer as

<h3>22 g/mL</h3>

Hope this helps you

a) Provide equation of K of this reaction, use symbol " ^ " for exponents. That means 1000 = 10^3 and 1/100 is 10^(-2). b) How m
stealth61 [152]

Answer and Explanation:

a. The equation of K of this reaction is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

K = \frac{(D)^5 (E)^7 (F)}{(A)^3 (B)^5 (C)^4}

b. The moles of compound F is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

               2 moles

Now, the mole of produced is

= \frac{1}{4} \times \ moles\ of\ c

Now, we will the value of c by using the above equation

= \frac{1}{4} \times 2

After solving the above equation we will get

0.5 moles
