Which equation represents energy being absorbed as a bond is broken.

1 answer:

7 0

There are different ways energy is absorbed. The equation that represents energy being absorbed as a bond is broken is H2 + energy → H + H

Energy is known to be taken in or absorbed so as to break bonds. Bond-breaking is referred to as an endothermic process. In this process, Energy is released when new bonds form. Bond-making is also known to be an exothermic process.

Potential energy is simply known to be the type of energy that is linked to an object's potential to do work.

Chemical energy is known to be the type of energy that is said to be released from the breakdown of chemical bonds.

Miguel can use all or part of his $25 gift card to make a music purchase. Each song costs $1. 50, and there is a $1. 00 per acco

Leviafan [203]

Answer: The answer is the first one and the last one.

Explanation: If an account cost $1 and each song is 1.5x. It has to be less than or equal to 25. So it would be $1 for (the account plus) 1.5x for (how many songs he buys) is less than or equal to 25 (the ammount on the gift card).

List one change in bug morphology that you would reasonably expect in bug populations that have been living on golden rain trees

marysya [2.9K]

Answer:

(a) In this case, small bugs are more likely to have relative fitness on the new food source.

(b) A change that will occur in bug morphology is that the female bugs will turn out to be the same size as the male bugs.

(d) Yes, the dispersing bug would have higher fitness as they will be able to easily get access to new resources once the previous one has run out, whereas the bugs with less developed fight muscles will not be able to do so.

Hope that answers the question, have a great day!

In a recent year, about 22% of Americans 18 years and older are single. What is the probability that in a random sample of 200 A

Pie

Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with $\mu = np, \sigma = \sqrt{np(1-p)}$ .

In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:

$\mu = np = 200(0.22) = 44$

$\sigma = \sqrt{np(1 - p)} = \sqrt{200(0.22)(0.78)} = 5.8583$

The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is <u>1 subtracted by the p-value of Z when X = 30.5</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{30.5 - 44}{5.8583}$

Z = -2.3

Z = -2.3 has a p-value of 0.0107.

0.0107 = 1.07% probability that more than 30 are single.
