Ethane (C2H6) is one of many compounds that burns in oxygen to form carbon dioxide and water, as represented by the equation.
2C2H6 + 7O2 → 4CO2 + 6H2O
Which substance is a product in this reaction?
carbon (C)
oxygen (O2)
water (H2O)
ethane (C2H6)
Answers
Answer:
Water (H2O)
Step-by-step explanation:
When hydrocarbons undergo combustion reactions (I.e reactions with oxygen) carbon (iv) oxide and water are usually produced.
In this case, the only difference is the numbe of moles between the product and reactant
Equation of reaction;
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Reactants:
1. Ethane = C₂H₆
2. Oxygen = O₂
Product:
1. Carbon(iv) oxide = CO₂
2. Water = H₂O

what is the value of y
Answers
We can solve for y by isolating it on one side of the equation.
6x - y = x --> subtracting x from both sides
5x - y = 0 --> subtracting 5x from both sides
-y = -5x
y = 5x
So the value of y is 5 times x.
Answer: y = 5x

To define Payroll tax.
Now, Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.
These taxes are withheld to fund various government programs and services.
Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.
The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
Answers
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
4 minutes of news for every 25 minutes of music.
This means,
25 minutes music = 4 minutes news
Multiply 60/25 on both sides.
60 minutes music = 60/25 x 4 minutes news
60 minutes music = 9.6 minutes news
1 hour of music = 9.6 minutes of news

(1440) + 295.25 + (-33.50)
to find today's total sales.
Answers
Answer:
Nina is not correct because 393.5$ less then yesterday's ticket sales.
Step-by-step explanation:
To find total sales she he is not correct because
3 / 4 of 1440 = 1,080$ ticket sales from yesterday
and 295.25 - 33.50 = 261.75$
Therefore, ( 3 / 4 * 1440 ) + ( 295.25 - 33.50 ) = 1,341.75$ sale of today
Ticket from yesterday and today
1,080 - 1,341.75 = 393.5
393.5$ less then yesterday's ticket.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4
Answers
1. First, divide both sides of the equation by 4.
1÷4 x³/4 = –27/4/4
2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.
3. Then, to solve for x, take the cube root of both sides of the equation.
Cube root of x³ = cube root of –27
4. To check your answer, plug in -3 for x in the original equation and solve.
1÷4 x³ = –27/4
1÷4 (-3)³ = –27/4
1÷4 (-27) = –27/4
1 = 1
Since 1 = 1, the answer checks out.
Therefore, the solution to the equation is x = -3.
