Write the balanced equation for the reaction of dilute sulfuric acid. H2so4 , with sodium hydroxide
Aleksandr [31]

Answer:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

Explanation:

This question is describing the neutralization reaction between dilute sulfuric acid (H2SO4) and sodium hydroxide (NaOH). These two compounds combine to form sodium salt and water as products (see the chemical equation below).

H2SO4 + NaOH → Na2SO4 + H2O

However, this equation is not BALANCED because the number of atoms of each element are not the same on both sides of the equation. To balance the equation, COEFFICIENTS are used as follows:

H2SO4 + 2NaOH → Na2SO4 + 2H2O

From this equation, the atoms of hydrogen (H), sulphur (S), oxygen (O), sodium (Na) are now equal on both sides, hence, it is said to be BALANCED.

A sample of methane gas occupies 4.50 gallons at a temperature of 80.0 F. If the pressure is held constant, what will be the vol
Marat540 [252]

Answer:

21.19 L or 5.6 gallons

Explanation:

Data Given

initial volume V1 = 4.50 gallons

convert volume from gallons to L

                               1 gallon = 3.78541 L

                               4. 50 gallon = 3.785 L x 4.50

So,                        

initial volume V1 =  17.03 L

final Volume V2 = ?

initial Temperature T1  = 80° F

convert Temperature to Kelvin

                              T1 = ( 80° F -32) / 1.8 +273

                               T1 = 26.7° C + 273 = 299.7 K

final Temperature T2 = 100° C

convert Temperature to Kelvin

                                  T2 = 100° C + 273 = 373 K

Solution:

This problem will be solved by using charles' law equation at constant pressure.

The formula used

                      V1 / T1 = V2 / T2

As we have to find out volume, so rearrange the above equation

                      V2 = V1 x T2 / T1

Put value from the data given and conversion information in above equation

V2 =  17.03 L x 373 K / 299.7 K

V2 =  21. 19 L

So the final volume of Methane gas = 21.19 L

Or for Volume in gallons

1 L = 0.26

21.19 x 0.264 = 5.6 gallons

To draw a complete lewis structure of one molecule of water, how many electrons must be shown?
love history [14]
In the Lewis structure, each single bond drawn between elements contain two electrons. The electron dots represent the lone pairs. These are the electrons that take part in the reaction. To obey the octet rule, the oxygen must have eight electrons around it. The hydrogen is exempted from this rule. Therefore, you have to show two electrons.
