So, HCl + NaOH —> NaCl + HOH

Consider the following reaction: Consider the reaction 2NO(g)+Br2(g)⇌2NOBr(g) ,Kp=28.4 at 298 K In a reaction mixture at equilib

Vitek1552 [10]

Answer: partial pressure of NOBr is 7792 atm

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

$2NO(g)+Br_2(g)\rightleftharpoons 2NOBr(g)$

Equilibrium constant is given as:

$K_{p}=\frac{[p_{NOBr}]^2}{[p_{NO}]^2\times [p_{Br_2}]^1}$

$28.4=\frac{[p_{NOBr}]^2}{[(119)^2\times (151)^1}$

$[p_{NOBr}]=7792$ atm

Partial pressure of NOBr is 7792 atm

A plane has a cruising speed of 100 miles per hour when there is no wind. At this speed, the plane flew 600 miles with the wind

alina1380 [7]

The solution for this problem is:
Let x = speed of wind

Speed of plane with the wind = x + 100

Speed of plane against the wind = 100 -x

We will be using the formula for distance which is (Rate)(Time), getting the formula for time would be distance/rate Time to travel 600 miles with the wind = Time to travel 400 miles against the wind 600/(x + 100) = 400/(100 - x)

400(x + 100) = 600(100 - x)

400x + 40000 = 60000 - 600x

1000x = 20000

x = 20000/1000

x = 20 mph

A sample of an ideal gas has a volume of 0.500 L at 25 degrees celcius and 1.20 atm pressure. What is its volume at 75 degrees c

NemiM [27]

The ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K

A system at equilibrium has two aqueous products and two aqueous reactants. An additional amount of one of the products is added

devlian [24]

Answer: c. the amounts of the reactants

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given reaction:

$A(aq)+B(aq)\rightleftharpoons C(aq)+D(aq)$

If the concentration of one of the products is increased, so according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease of concentration of product takes place. Therefore, the equilibrium will shift in the left direction i.e. towards the reactants and thus more reactants will be formed.
