The enthalpy change for combustion of 15.0 g of ethanol can be calculated using the equation δH = -555 kJ/mol x (moles of ethanol).

Ethanol, or ethyl alcohol, is a type of alcohol with the molecular formula C2H5OH. It is a colorless, volatile, flammable liquid that has a somewhat sweet odor and taste. Ethanol is a renewable fuel that can be derived from corn, wheat, barley, and other grains, as well as from cellulose-based feedstocks.

To calculate the moles of ethanol, 15.0 g (the mass given) must be divided by the molar mass of ethanol, 46.0 g/mol.

15.0 g/46.0 g/mol = 0.326 mol

Therefore, the enthalpy change for combustion of 15.0 g of ethanol is given by the equation:

δH = -555 kJ/mol x 0.326 mol = -180.3 kJ

Answer:x-264.62

Explanation:you can set up a proportion

16.0/130 = x/2150

by cross multiplying you get

130x = 34400

divide by 130 and get

x-264.62

The value of the variable x in terms of c will be x = (7c − 6c³) / (3c² − 6).

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The equation is given below.

2(−3x + c) = −3(2c² + cx)c + 5c

Simplify the equation for x, then the equation will be

2(−3x + c) = −3(2c² + cx)c + 5c

−6x + 2c = −6c³ − 3c²x + 5c

3c²x − 6x = 2c + 5c − 6c³

(3c² − 6)x = 7c − 6c³

x = (7c − 6c³) / (3c² − 6)

The value of the variable x in terms of c will be x = (7c − 6c³) / (3c² − 6).

Answer:  Angle formed with height and hypotenuse is 40 degrees

Explanation:

Hi, to answer this question we have to analyze the information given:

Since the triangle is a right triangle it has a right angle that has a value 90 degrees.

Since the sum of the interior angles is equal to 180 degrees:

180 = x +50 + 90

Solving for x:

180-90-50 =x

40° =x

Explanation:

Quadrilateral ABCD is both a parallelogram and a rhombus.

The figure ABDC with diagonal BC, with the congruent sides AB and DC, angle A is congruent to angle D, and sides AC and DB are congruent is a parallelogram. This is based on the definition of a parallelogram which is a quadrilateral with opposite sides that are parallel and congruent to each other.

Also, opposite angles of a parallelogram are congruent. Therefore, angle A and angle C are congruent. Additionally, angle B and angle D are also congruent because they are opposite angles of a parallelogram.The diagonal of a parallelogram cuts it into two congruent triangles.

Triangle ABD and triangle CBD are congruent triangles, since their sides are congruent, and angles A and D, and angles B and C, are congruent by the given information.

Therefore, their included angles ABD and CBD are also congruent. Because their opposite sides are congruent, quadrilateral ABCD is a rhombus. A rhombus is a parallelogram with all sides congruent. This implies that sides AB, BC, CD, and DA are all equal.

In conclusion, quadrilateral ABCD is both a parallelogram and a rhombus.

Linear inequality or the Linear inequalities are the expressions where any two values are compared by the inequality symbols ‘<’, ‘>’, ‘≤’ or ‘≥’

For example: 3x<5,5x+5>7

Linear equations are a combination of constants and variables.

For example:

y=ax+b

The values of the variable that makes a linear equation satisfy are the solution of the linear equation or linear inequality. So, the correct option for solving the linear inequality and linear equation is (B).

Solving a linear inequality is similar to solving a linear​ equation, because goals of solving a linear inequality and solving a linear equation are the​ same, that​ is, to get the variable alone.

Answer:

The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.

Explanation:

Answer:

Explanation:

P(X > 6) = ?

P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)

P(X > 6) = 0.118 + 0.035 + 0.004

P(X > 6) = 0.157

Thus the probability of getting 6 or more girls in 8 births is 0.157

Since 60° is one-sixth (1/6) of 360°, then the length of the arc subtended by a central angle of 60° is one-sixth (1/6) of the circumference of the circle.

The test statistic is 0.20.

The critical value is 0.2.

The p-value is 0.038.

Since the p-value is less than the alpha level of 0.01, we reject the null hypothesis and conclude that less than 20% of the pumps are inaccurate.

What is Hypothesis
Hypothesis is an educated guess or proposed explanation made on the basis of limited evidence as a starting point for further investigation. It is an important part of the scientific method, where a hypothesis is developed through the use of scientific inquiry and experimentation. A hypothesis is usually based on prior knowledge or observation and is tested to determine its validity. By testing a hypothesis, scientists can either reject or accept it, which in turn leads to the development of a theory. Hypotheses are essential in advancing scientific knowledge, as they lead to further research and help scientists to think critically about the world around them.

For the fiscal year​ 2007, a tax authority audited 1.91​% of individual tax returns with income of​ $100,000 or more. Suppose this percentage stays the same for the current tax year. What is the probability that two randomly selected returns with income of​ $100,000 or more will be​ audited?

Answer:

The probability of auditing two individual tax return worth $100,000 or more is 0.00036481

The probability of auditing an individual tax return which is $100,000 or more = 1.91% = 0.0191

Therefore, the probability of auditing any tax return with $100,000 or more will be 0.0191

Thus, the probability of auditing two tax returns with $100,000 or more will be :

First event = 0.0191

Second event = 0.0191

So, the resulting probability is (0.0191 × 0.0191) = 0.00036481

Therefore, the probability of auditing individual tax returns of $100,000 or more is 0.00036481

Physical quality refers to a tangible object or entity's characteristics, attributes, or properties that determine its level of excellence, durability, reliability, or overall performance.

It refers to the objective measures of how well a product or service meets the established standards or specifications.

Physical quality is typically evaluated based on factors such as appearance, functionality, structural integrity, strength, precision, consistency, and other physical attributes.

For example, in manufacturing, physical quality may involve assessing the dimensional accuracy, material properties, surface finish, and overall workmanship of a product. In the context of services, physical quality may refer to the condition and maintenance of physical facilities, equipment, or infrastructure.

Maintaining high physical quality is important for customer satisfaction, as it directly affects the usability, reliability, and longevity of a product or service. By meeting or exceeding customer expectations in terms of physical quality, businesses can enhance their reputation, build customer loyalty, and gain a competitive advantage in the marketplace.
