Very simple it just closes the tab out completely for you to never see it again!

Hope this helps :)

P.S. You should of posted this in the Computers Section

By pressing Alt+F4 it closes the current window so if you had pressed Alt+F4 while playing a game the game window would have closed

Question
In a titration of 0.35 M HCl and 0.35 M NaOH, how much NaOH should be added to 45.0 ml of HCl to completely neutralize the acid?
Solution 1
It would be the same amount. So, 45 ml of NaOH is required to be added to the 45 ml of HCI to neutralize the acid fully. Here is a brief calculation:

Firstly, here is your formula: M(HCI) x V(HCI) = M(NaOh) x V(NaOH) 
With the values put in: 0.35 x 45 = 0.35 x V(NaOH) 
= 45 ml. 
There is 45 ml of V(NaOH)

Question
What is the relationship between the size of an object and the amount of friction that is present
Solution 1
If an object is heavier with a greater mass, then its friction levels will also increase. This is due to the force of gravity. Speaking of its size, it depends on its weight. So basically, if the object is only physically big but has a low mass, then it barely has a relationship with friction. However, if it is big or small with a heavy weight, then the amount of friction will be more.

Question
The chemical equation below shows the decomposition of nitrogen triiodide (NI3) into nitrogen (N2) and iodine (I2). 2NI3 mc030-1.jpg N2 + 3I2 The molar mass of I2 is 253.80 g/mol, and the molar mass of NI3 is 394.71 g/mol. How many moles of I2 will form 3.58 g of NI3?
Solution 1

Answer:

0.0135 moles of iodine will be formed.

Explanation:

2NI_3\rightarrow N_2+3I_2

Moles of nitrogen triiodide =\frac{3.58 g}{394.71 g/mol}=0.0090 mol

According to reaction 2 moles of nitrogen triiodide gives 3 moles of iodione gas.

Then 0.0090 mol of nitrogen triiodide will give:

\frac{3}{2}\times 0.0090 mol=0.0135 mol

0.0135 moles of iodine will be formed.

Solution 2
The molar mass of I2 is 253.80 g/mol, and the molar mass of NI3 is 394.71 g/mol. How many moles of I2 will form 3.58 g of NI3?


0.0136 
Question
What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 15°C? A) 0.033 cal/g°c B) 0.33 cal/g°c C) 0.99 cal/g°c D) 1.33 cal/g°c
Solution 1
The specific heat capacity  the substance is calculated  using  the below formula

Q(heat) = Mc delta T
Q =1560  cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?

by making c the subject of the formula 
c=Q/m delta T
= 1560  cal/ 312g x 15 c = 0.33 cal/g/c (answer B)


Question

Solution 1

Answer:

Isomers have identical Molecular formulas; however, they have different Structural formulas.

Explanation:

Hello,

In this case, it is widely known that isomers have identical molecular formulas and different structural formulas as shown for the compound having the following molecular formula:

C_2H_6O

In such a way, two feasible compounds could have the aforesaid molecular formula, which are dimethyl ether and ethanol respectively as shown below:

CH_3-O-CH_3\\CH_3-CH_2-OH

Best regards.

Solution 2
Molecular, structural.
Question
Define the term bond angle
Solution 1
Is the angle formed between three atoms across at least two bonds
Question
Identify the type of hybrid orbitals present and bond angles for a molecule with a tetrahedral shape
Solution 1

Answer: If molecular geometry is tetrahedral, there are four bond pairs of electrons and thus hybridization is sp_3

Explanation: Formula used

:{\text{Number of electrons}} =\frac{1}{2}[V+N-C+A]

where, V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

The number of electrons is 4 for tetrahedral shape that means the hybridization will be sp^3.

The electron pairs will try to minimize the repulsions and will occupy a position of maximum stability. This molecule is made up of 4 equally spaced sp^3 hybrid orbitals forming bond angles of 109.5^0
