1. 2.0 mL/s x 4.0 hrs = ? L

How do you do this conversion problem

Answer:

a) r = k × [A] × [B]²

b) 3

Explanation:

Let's consider the following generic reaction

A + B + C ⇒ Products

The generic rate law is:

r = k × [A]ᵃ × [B]ᵇ × [C]ⁿ

where

This reaction is first order in A, second order in B, and zero order in C. The rate law is:

r = k × [A]¹ × [B]² × [C]⁰

r = k × [A] × [B]²

The overall order of the reaction is the sum of the individual reaction orders.

1 + 2 + 0 = 3

Answer:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

Answer:

281s

Explanation:

Given parameters:

Speed of the scooter  = 1.45min per mile

Fuel economy of engine  = 85miles per gallon

Quantity of fuel  = 145mL

Unknown:

Time of travel with the volume of fuel given  = ?

Solution:

To solve this problem, we need to find the distance the fuel will last.

 Rate of fuel consumption by the engine  = 85miles per gallon

Convert 145mL to gallons;

                3785.41mL  = 1 gallon

               145mL will therefore give [tex]\frac{145}{3785.41}[/tex]    = 0.038gallons

So;

   Distance covered  = 85miles per gallon  x 0.038gallons  = 3.23miles

From;

             Rate of travel  = [tex]\frac{time }{distance}[/tex]  

       Time  = rate of travel x distance  = 1.45 minutes per mile x  3.23miles

     Time  = 4.7min

             1 min  = 60s

            4.7min  = 4.7 x 60 = 281s

Explanation:

The theoretical yield of NaCl : 15 mol

Given

15 mol Na

15 mol Cl₂

Required

The theoretical yield of NaCl

Solution

Reaction

2Na + Cl₂ ⇒ 2NaCl

A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Find limiting reactant (mol : coefficient) :

Na = 15 : 2 = 7.5

Cl₂ = 15 : 1 = 15

The limiting reactant = Na(smaller ratio)

Mol of NaCl based on mol Na as limiting reactant.

From the equation, mol ratio of Na : NaCl = 2 : 2, so mol NaCl = 15 mol

Explanation:

400 + 20 + 420

Explanation:

We can summarize the reaction shown as:

                2F₂  +   I₂  →   2F₃I

Since I is purple

         F is the green

The number of I atoms in the reactants is greater than the number in the product

False:

The number of I atoms on both side of the expression is 2

There are 4 atoms of F in both the reactants and the products.

False:

There are 4 atoms of F on the reactant side and 6 atoms of F on the product side

The illustration represents a valid chemical transformation. True or false

False

The reaction does not represent a valid chemical transformation because in a valid chemical transformation, the number of atoms on both sides of the expression must be the same.

Answer:

Formula for acceleration is

Answer:

w = 7376.6 J

Explanation:

To calculate the work done in the system, we need first to calculate the number of moles of all compounds.

The following expression, that comes from the 1° law of thermodynamic, will help you to get the work:

w = ΔnRT

Where:

Δn: difference in the number of moles between products and reactants

R: constant universal of gases (8.314 J / mol K)

T: Temperature in Kelvin.

As we are doing this reaction in STP, then the Pressure is 1 atm, and temperature is 0 °C or 273 K.

Now, we already have the moles of Cu₂O, let's see, according to the balanced reaction, how many moles we should have of O₂ and CuO.

If 1 mole of O₂ reacts with 2 moles of Cu₂O then 6.5 moles of Cu₂O will be:

moles O₂ = 6.5 moles Cu₂O * (1 mole O₂/2 moles Cu₂O) = 3.25 moles O₂

If 2 moles of Cu₂O produces 4 moles of CuO, then 6.5 moles will be:

moles CuO = 6.5 moles Cu₂O*(4 moles CuO/2 moles Cu₂O) = 13 moles CuO

Now that we have the moles, let's calculate the value of Δn.

Δn = moles product - moles reactants

Δn = 13 - (6.5 + 3.25) = 3.25 moles

Now, we can calculate the work done in the system:

w = 3.25 * (8.314 * 273)

Answer:

74.73 ×10²³ molecules

Number of moles = 12.41 mol

Explanation:

Given data:

Mass of C₄H₆ = 671 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles:

Number of moles = mass/molar mass

Number of moles = 671 g/ 54.091 g/mol

Number of moles = 12.41 mol

Number of molecules:

1 mole contain 6.022×10²³ molecules

12.41 mol × 6.022×10²³ molecules / 1 mol

74.73 ×10²³ molecules

Answer:

It is a chemical change

Explanation:

Fat is a triglyceride. Triglycerides form soap when they come into contact with sodium hydroxide.

Now, we know that a chemical change is one in which a new substance is formed and it is not easily reversible. Heat is also given out or absorbed in the process.

Now the combination of sodium hydroxide and fat yields a new substance called soap. The appearance of the new substance conclusively proves that a chemical change has taken place.
