Limonene is an oil from oranges and lemons. Click on all the carbon


atoms its structures that have a trigonal planar molecular geometry.

Answers

Answer:

See explanation

Explanation:

Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.

There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.

Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?

Answers

Answer:

500 hits

Explanation:

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?

Solution:

Given that:

20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz

10 webs = 1 futz; hence:

1 web = 1 web * 1 futz / 10 webs = 0.1 futz

1 web = 0.1 futz

1 futz = 2 geese; hence:

0.1 futz = 0.1 futz * 2 geese / 1 futz

0.1 futz = 0.2 geese

Therefore, 1 web = 0.1 futz = 0.2 geese

1 web = 0.2 geese

This means that 20 hits = 1 web = 0.2 geese

20 hits = 0.2 geese

5 geese = 5 geese * 20 hits / 0.2 geese

5 geese = 500 hits

Help out please????

Answers

Answer:

B. X= Elements, Y= Compounds

Explanation:

An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.

Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.

A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?

Answers

Answer:

Explanation:

The responding variable always is measured against the variable that you have control over.

In this case, you have control over the volume of air.

The responding variable is the amount the plant has grown.  This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
