You will then write a one- to two-paragraph summary describing your chosen type of biotechnology. You will then need to argue for either the benefits or the risks of your chosen type. Your arguments should present your position, and then give the evidence that led you to this position. Be sure to include the following in your argument:

a description of your chosen type of biotechnology (genetic engineering, cloning, or artificial section)
one benefit or one risk for the individual (based on whether you are for or against it)
one benefit or one risk for society (based on whether you are for or against it)
one benefit or one risk for the environment (based on whether you are for or against it)

The volume of hydrogen gas produced can be measured using a gas syringe.

Method:-

- Support a gas syringe with a stand, boss and clamp.

- Using a measuring cylinder, add 50 cm3 of dilute hydrochloric acid to a conical flask.

- Add a 3 cm piece of magnesium ribbon to the flask. Immediately connect the gas syringe and start a stop clock.

- Record the volume of gas produced every 5 seconds. Continue timing until no more gas is given off.

- When the reaction is complete, clean the apparatus as directed by your teacher.

- Repeat steps 1 to 5 with different concentrations of hydrochloric acid.

Based on the fact that only herbicide was used to grow the corn, this means that the resistance type of the corn are caterpillars.

Herbicide are chemicals used to control and kill weeds that could hinder crop production while insecticides are chemicals used to control insect pests.

According to this question, a field of corn was grown with 250 L/ha herbicide and no insecticide. This means that only herbs or weeds are being controlled on the field.

Therefore, it can be said that the corn plants are the type that are resistant to caterpillars, which are examples of insects.

The number of moles contained in 39 L of F2 gas at STP is 1.74mol. Details on how to calculate number of moles can be found below.

The number of moles of a gas at STP can be calculated using the following formula:

PV = nRT

Where;

At STP, the following applies:

1 × 39 = n × 0.0821 × 273

39 = 22.41n

n = 1.74mol

Therefore, the number of moles contained in 39 L of F2 gas at STP is 1.74mol.

In a reaction involving sodium metal and chlorine gas, the amount of sodium metal required to react with 0.950 grams of chlorine gas would be 0.62 grams

From the balanced equation of the reaction:

2Na (s) + Cl2 (g) ---------> 2NaCl (s)

The mole ratio of Na to Cl2 is 2:1.

Mole of 0.950 grams of chlorine gas = 0.950/70.906

                                                             = 0.0134 moles

Equivalent mole of Na = 0.0134 x 2 = 0.0268 moles

Mass of 0.0268 moles Na = 0.0268 x 22.99

                                           = 0.62 grams

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

Acids or bases with strong bonds remain as molecules in solutions known as weak acids or bases. The acids or bases with weak bonds easily dissociate into ions and are called strong acids or bases.

Acid is proton donor hydrogen containing substance. Base is proton acceptor molecule.

It can be predicted by pH indicator. pH with value less than 7 indicate acidity and value with more than 7 denotes base, and the one with value 7 is considered as neutral.

Thus, based on bond strength and its dissociation in the water makes it strong acid or weak base.

Answer:

They are organized from least to greatest by their atomic number.

Explanation:

Hope that helps!

Answer:

Explanation:

Elements are listed in numerical order by atomic number. The atomic number is the number of protons in an atom of that element. So element number 1 (hydrogen) is the first element. Every atom of hydrogen has 1 proton. Until a new element is discovered, the last element on the table is element number 118. Every atom of element 118 has 118 protons. This is the biggest difference between today's periodic table and Mendeleev's periodic table. The original table organized the elements by increasing atomic weight.

Each horizontal row on the periodic table is called a period. There are seven periods on the periodic table. Elements in the same period all have the same electron ground state energy level. As you move from left to right across a period, elements transition from displaying metal characteristics toward nonmetallic properties.

Each vertical column on the periodic table is called a group. Elements belonging to one of the 18 groups will share similar properties. Atoms of each element within a group have the same number of electrons in their outermost electron shell. For example, elements of the halogen group all have a valence of -1 and are highly reactive.

There are two rows of elements found below the main body of the periodic table. They are placed there because there wasn't room to put them where they should go. These rows of elements, the lanthanides and actinides, are special transition metals. The top row goes with period 6, while the bottom row goes with period 7.

Each element has its tile or cell in the periodic table. The exact information given for the element varies, but there is always the atomic number, the symbol for the element, and the atomic weight. The element symbol is a shorthand notation that is either one capital letter or a capital letter and a lowercase letter. The exception is the elements at the very end of the periodic table, which have placeholder names (until they are officially discovered and named) and three-letter symbols.

The two main types of elements are metals and nonmetals. There are also elements with properties intermediate between metals and nonmetals. These elements are called metalloids or semimetals. Examples of groups of elements that are metals include alkali metals, alkaline earths, basic metals, and transition metals. Examples of groups of elements that are nonmetals are the nonmetals (of course), the halogens, and the noble gases.

As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite. Speleothems form at varying rates as calcite crystals build up. They are formed from condensation inside a cave, dripping off the ceiling.

The concentration in ppm of sodium fluoride in tap water is 1.6 ppm.

ppm is  an abbreviation for parts per million. It can also be expressed as  milligrams per liter of a solution.It is a measurement which is equal to mass of a substance per unit volume .

One ppm is equivalent to the absolute fractional amount which is multiplied  by a million . It is a best way to describe smaller concentrations in a mixture such as that of gases,liquids or solids . It is a ratio of two quantities   which have  the same unit. In its full form ppm is expressed as one in a million part.

Depending on the substance being measured 1 ppm is expressed in many different ways, out of which preferred ways are microliters per liter , milligrams per liter and micrograms per liter.

For the given problem, concentration in ppm is found out as, since ppm is miiligrams  per liter the concentration is found out as follows:32 mg/20 kg (since kilograms  and liters  are  equivalent) =1.6 ppm

Thus, the  final concentration of sodium fluoride in tap water  which is fluorinated is 1.6 ppm.
