Answer:

c. Many of their bonds are C-C and C-H

Explanation:

The majority of bonds in carbohydrates and lipids( being an organic compound) are C-C and C-H. Like glucose, fructose or galactose ,etc.

These bonds are strong and do require a lot of energy to break. Thus, a lot of energy are required to break carbs and lipids into simpler compounds.Therefore, carbohydrates and lipids have high potential energy.

The correct answer is c.

Name two elements that have properties similar to those of beryllium and have average atomic masses higher than 130

sertanlavr [38]

In the periodic table, elements of the same group are characterized by having the same similar properties.
So, first we will check the elements that lie within the same group as <span>beryllium and then we will attempt to choose the elements with atomic mass higher than 130.

So, elements in the same group as </span>beryllium are: magnesium, calcium, strontium, barium and radium.
Among these elements, we will find that:
radium has atomic mass of 226 amu
barium has atomic mass of 137.327 amu

Based on this, the two elements would be barium and radium.

A jogger runs at an average speed of 5.9 mi/h.

madreJ [45]

She will cover distance in 3 days and 16 hours .the time will be 3:15 am on the fourth day.

Convert 5.9 miles/hour to feet/hour there are 5,280 feet in a mile

total distance covered = 47500

distance = rate x time

now, time = 47500/5280

time = 88 hours

88 hours = 3 Days and 16 Hours.

now the time will be 3 :15 am on the fourth day.

The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.

The distance traveled divided by the time taken is the most popular formula for calculating average speed. The alternative formula is to add the initial and final speeds together, then divide by 2.
