Answer 1

Answer:

1 Covalent Bond

Explanation:

__________________________________________________________

According to Answers,

There is one covalent bond in a chlorine molecule. The formula for a chlorine molecule is Cl2, which means that there are two chlorine atoms bonded together per molecule. The structural formula for a molecule of chlorine is Cl-Cl, in which the line in between the symbols for the two atoms represents a single covalent bond.

difference between fluids and nonfluids

Answers

Answer:

All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.

Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.

Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.

You bought your pig and it weighed 82 pounds. By fair your goal weight is 267 pounds. Your pig will gain 1 pound for every 3 pounds of feed. How much feed will you need to get your pig to it's goal weight? (show your work) (5) Feed costs $21.37 per 50 pound bag. How much will your feed cost be, to get your pig to it's goal weight? (5) MUST SHOW ALL WORK.

Answers

Number of feed = 555 pounds

Feed cost = $237.21

Further explanation

The main composition of algebraic expressions are:  

• 1. phrases/terms  

• 2. variable  

• 3. constants  

• 4. arithmetic operations  

• 5. coefficients  

• 6. exponent  

Initial weight = 82 pounds

Goal weight = 267 pounds

The difference in weight that must be achieved :

[tex]\tt 267-82=185~pounds[/tex]

The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed

The amount of feed must be given:

[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]

Feed costs $21.37 per 50 pound bag, so for 555 pounds :

[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

HCI is a strong acid. What particles would you expect to find in a solution of HCI(aq)?
HCI, H+ and Cl- particles
H+ particles only
H+ and Cl- particles
HCl particles only

Answers

it ionizes completely because it's a strong acid so no HCl particles will be found only H+ that reacts with H2O and Cl- so the 3rd option is correct

What is the difference between the atomic weight and the relative
atomic mass (RAM)?​

Answers

Answer:

Relative and average atomic mass both describe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.

Explanation:

Atomic weight is approximately equal to the number of protons and neutrons, with a little extra added by the electrons. The stability of the nucleus, and hence the atom's radioactivity, is heavily dependent upon the number of neutrons it contains.

Atomic mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number.

On the moon,When dropped from the same height Why does a flat sheet of paper fall more slowly than the same sheet when it is tightly crumpled into a ball?

Answers

Answer:

It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

3. What is found around the roots of some plants that turns nitrogen from the form we cannot use to the form we can use?

Answers

Answer:

Bacteria

Explanation:

Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.

Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.
