Answer:

The correct answer is - discovering or diagnosing the disease.

Explanation:

According to the question, this technology includes genetically modifying a common virus in order to destroy or kill the deadly brain tumor without affecting normal cells around the tumor, this technique is genetic engineering.

This technique can help in treating or curing the disease by killing the tumor cells and make them non-lethal. It can also prevent the tumor cells to grow and make them controlled. There is nothing mention related to diagnosing the disease in the question and it is not possible to find this tumor with help of such a technique.

Answer:

Cl2 acts as an oxidizing agent

Explanation:

The balanced equation is

Cl2+NaOH⟶NaCl+NaClO3+H2O

Cl2 acts as a reactant in this chemical reaction

Cl2 receives one electron and thus reduces itself from Cl2 to 2 Cl−. This indicates that 2Cl- will oxidize some other element and hence Cl2 act as an   oxidizing agent.

Answer:

23.8g

Explanation :

Convert 2.0M into mol using mol= concentration x volume

2.0M x 0.1L (convert 100mL to L since the units for M is mol/L)

= 0.2 mol

We can now find grams by using the molar mass of KBr

=119.023 g/mol (Found online) webqc.org

but can be be calculated by using the molecular weight of K and Br found on the periodic table

We can now calculate the grams by using grams=mol x molar mass

119.023g/mol x 0.2mol

= 23.8046 g

=23.8g (rounded to 1decimal place)

Explanation:

(a) a functional group is a special group of atoms or bonds in a compound that is responsible for the chemical reactions, behavior, and characteristics of that compound. (b) Functional group is present in both the compound is alcohol (-OH).

Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples are alcohols, amines, carboxylic acids, ketones, and ethers.

Key Points

Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form.

Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity.

Functional groups can be used to distinguish similar compounds from each other.

Key Terms

functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class.

functionalization: Addition of specific functional groups to afford the compound new, desirable properties.

Answer:

solid=(s)

Explanation:

A solubility table may be something your class may want you to memorize. Where an aqueous (aq) solution is formed by a soluble compound dissolving in water, our solvent. So if we refer to this solubility table, it says phosphate (PO4) is usually insoluble, so in the reaction it won't break down in water and will stay as a solid (s). The only exceptions are group 1 alkali metals or ammonium (NH4+).

Answer:

0.233M

Explanation:

M1 = 0.700M

V1 = 2L

V2 = 3L

M2 = ?

M1V1 = M2V2

(0.700)(2) = M2(3)

M2 = 0.233M

Answer:

balanced equation mole ratio 5 2 mol NO/1 mol O2

10.00 g O2 3 1 mol O2/32.00 g O2 5 0.3125 mol O2

20.00 g NO 3 1 mol NO/30.01 g NO 5 0.6664 mol NO

actual mole ratio 5 0.6664 mol NO/0.3125 mol O2 5 2.132 mol NO/1.000 mol O2

Because the actual mole ratio of NO:O2 is larger than the balanced equation mole

ratio of NO:O2, there is an excess of NO; O2 is the limiting reactant.

Mass of NO used 5 0.3125 mol O2 3 2 mol NO/1 mol O2 5 0.6250 mol NO

0.6250 mol NO 3 30.01 g NO/1 mol NO 5 18.76 g NO

Mass of NO2 produced 5 0.6250 mol NO2 3 46.01 g NO2/1 mol NO2 5 28.76 g NO2

Excess NO 5 20.00 g NO 2 18.76 g NO 5 1.24 g N

Explanation:

Son muchos los beneficios del catión monovalente (K+) en las plantas y cultivos, mencionaremos algunos:

-Interviene en el proceso de apertura y cierre de los estomas; el catión (k+) ayuda a que los estomas puedan realizar correctamente  el proceso de la fotosíntesis es decir  la absorción del dióxido de carbono para producir oxígeno y agua; este proceso ayuda a que la planta pueda fabricar su propio alimento es decir transformar materiales inorgánicos en orgánicos como azúcares y carbohidratos que son aprovechables por la planta para realizar diversas funciones catalíticas como la respiración celular,la fosforilación y la síntesis de proteínas; este proceso también contribuye a que la planta pueda almacenar y retener suficiente agua lo cual ayuda a evitar el estrés hídrico en la planta.

Por lo tanto si la planta tiene una buena concentración de potasio como catión monovalente(k+); es posible que tenga un buen crecimiento y desarrollo radicular ,así mismo la calidad de los cultivos será muy buena,seran cultivos muy nutritivos y saludables. Algunos cultivos que necesitan una alta cantidad de potasio son los cítricos y el banano.

The expected outcome of carrying out this step as planned is :

B. The resulting pH will be less than 7 because potassium hydroxide is less concentrated than the hydrochloric acid.

The expected outcome of carrying out this step as planned is the resulting pH will be less than 7 because potassium hydroxide is less concentrated than the hydrochloric acid.

pH may be a degree of how acidic/basic water is.

The run goes from - 14, with 7 being unbiased. pHs of less than 7 demonstrate causticity, while a pH of more noteworthy than 7 demonstrates a base.

pH is truly a degree of the relative amount of free hydrogen and hydroxyl particles within the water

Thus, the correct answer is B.

Answer:

466.65 K

Explanation:

Using the formula of  Pressure law,

P/T = P'/T'.................... Equation 1

Where P = Intial pressure of gas, T = Initial temperature of gas, P' = Final pressure of gas, T' = Final temperature of gas.

make T' The subeject of equation 1

T' = (P'T)/P................... Equation 2

From the question,

Given: P = 500 Torr = (500×133.322) N/m² = 66661 N/m², T = 35°C = (35+273) = 308 K, P' = 101000 N/m²( Standard pressure)

Substitute these values into equation 2

T' = (101000×308)/66661

T' = 466.65 K

Answer:

Kc ≅ 100 (1 sig. fig.)

Explanation:

              2NH₃(g)       ⇄      N₂(g)   +   3H₂(g)

C(i)         3.00 mol/L             0                0

ΔC             -2x                       +x              +3x

C(eq)     0.600 mol/L            x                3x

3.00 - 2x = 0.600  =>  x = 3.00 - 0.600/2 = 1.2 mole/L

At equilibrium Kc = [N₂][H₂]³/[NH₃]² = (x)(3x)³/(3·1.2)² = (1.2)(3.6)³/(0.600)² = 155.52 (calculator)

Rounds to 1 sig. fig. based on given 3.00 moles NH₃(g)' Kc ≅ 100.

Answer:

1.05 atm

It should be 1 atm = 760 mm; therefore, 798 mm x (1 atm/760) = about 1.05 atm.

The value of pressure in atm that would be equal to 798 mmHg is 1.05 atmospheric.

Pressure is a physical quantity or a kind of force which is perpendicularly applied on the surface area of any object so that force is equally distributed on that surface.

Pressure will be maesured by various unit and have relation with one another.

As we know that, 1 atm = 760 mmHg

Or 1 mmHg = 1/760atm

Given quantity of pressure is 798 mmHg and we calculate this quantity by multiply this value by 1/760 and we get,

798 mmHg = 798mmHg × 1/760atm/mmHg = 1.05 atm

Hence required value of pressure is 1.05 atm.
