an organic pesticide was decomposed by an oxygen combustion procedure to convert the chlorine in the molecule to water soluble chloride the chloride was then precipitated as AgCl A 0.7715 gram precipitate was obtained from 500 grams of pesticide Calculate the percentage chlorine in the pesticide

Answers

Answer:

0.0382%

Explanation:

Given that:

Silver chloride = AgCl

Molar mass of AgCl = (107.87 + 35.5) = 143.37 g/mol

Chlorine, Cl = 35.5

143.37g/mol of AgCl = 35.5 g of Cl

Hence, 1 g AgCl will give ; (35.5 / 143.37)

1g AgCl = 0.2476 g Cl

In 0.7715 g AgCl, ; (0.2476*0.7715) g Cl

= 0.1910 g Cl

Therefore, percentage of Cl in 500g sample:

(Mass of Chlorine / mass of sample) * 100%

(0.1910 / 500) * 100%

0.000382 * 100%

= 0.0382%

Do atoms have the same number of protons as its neutrons? I know that atoms can have different number of electrons compared to protons, but does the number protons and neutrons stay equal?

Answers

Not necessarily. The atomic mass equals the number of protons+neutrons, but they don’t necessarily have to be the same. For example, for a carbon isotope of 14C, there would be 6 protons but 8 neutrons.

Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. How does the addition of arsenic change the conductivity of silicon?


a) An atom of arsenic has one fewer valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom gains an electron.

b) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity decreases because the arsenic atom loses the electron.

c) An atom of arsenic has one fewer valence electron and fewer electron shells than an atom of silicon, so the conductivity increases because the arsenic atom gains an electron.

d) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron.


HAD TO POST THIS THIS BC THE OTHER POSTED IS WRONG

Answers

Answer:

d) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron.

Explanation:

This is an example of a n-type semiconductor. The additional electron introduced to the 'grid' of silicon atoms causes an increase in the conductivity of the silicon. This additional electron is introduced as arsenic loses its extra electron.

Answer:

D is the answer, the other one is wrong.

Answers

Answer: Energy of reactants = 30, Energy of products = 10

Exothermic

Activation energy for forward reaction is 10.

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and [tex]\Delta H[/tex] for the reaction comes out to be negative.

Energy of reactants = 30

Energy of products = 10

Thus as energy of the product < energy of the reactant, the reaction is exothermic.

Activation energy [tex](E_a)[/tex] is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

[tex]E_a[/tex] for forward reaction is (40-30) = 10.

An ideal gas is in a sealed rigid container. The average kinetic energy of the gas molecules depends most on An ideal gas is in a sealed rigid container. The average kinetic energy of the gas molecules depends most on the temperature of the gas. the number of molecules in the container. the size of the container. the mass of the molecules.

Answers

Answer:

The temperature of the gas.

Explanation:

According to the kinetic molecular theory, the molecules of a substance are in constant random motion.

If an ideal gas is contained is a sealed rigid container, the average velocity of the gas molecules is dependent of the temperature of the gas.

Recall that temperature is defined as the average kinetic energy of the molecules of a body.

mass of 63 g and a volume of 9 cm^3. What is the density of this nugget?

Answers

Answer: The density of this nugget is [tex]7\text{ g cm}^{-3}[/tex] .

Explanation:

We are given that,

Mass of nugget = 63 g

Volume = [tex]9\ cm^3[/tex]

The computation of density of a substance is given by :-

[tex]\text{Density}=\dfrac{\text{Mass}}{\text{Volume}}\\\\\Rightarrow\ \text{Density}=\dfrac{63}{9}\text{ g cm}^{-3}[/tex]

[tex]\Rightarrow\ \text{Density =}7\text{ g cm}^{-3}[/tex]

Therefore, the density of this nugget is [tex]7\text{ g cm}^{-3}[/tex] .

a A student decreases the temperature of a 484 cm ^ 3 balloon from 570 K to 285 Assuming constant pressure, what should the new volume of the balloon be? Round your answer to one decimal place.

Answers

Answer:

242 cm³.

Explanation:

The following data were obtained from the question:

Initial volume (V₁) = 484 cm³

Initial temperature (T₁) = 570 K

Final temperature (T₂) = 285 K

Pressure = constant

Final volume (V₂) =?

The new volume (i.e final volume) of the balloon can be obtained by using the Charles' law equation as illustrated below:

V₁/T₁ = V₂/T₂

484 / 570 = V₂ / 285

Cross

484 × 285 = 570 × V₂

137940 = 570 × V₂

Divide both side by 570

V₂ = 137940 / 570

V₂ = 242 cm³

Therefore, the new volume of the balloon is 242 cm³

Which statement gives a disadvantage of multicellular organisms?


A. They need small amounts of energy


B. They reproduce slower than unicellular organisms


C. They can perform more functions


D. Cells are able to provide support

Answers

Answer: B. They reproduce slower than unicellular organisms

Explanation:

In unicellular organisms there is a single cell which performs all the functions like digestion, respiration, and reproduction. The cell reproduce by cell division. The single parent cell divides into two identical daughter cells. But multicellular organisms exhibit multiple cells and their reproduction is complex. They reproduce by sexual mode of reproduction in which separate sex cells are produced when they fuse form zygote which is the precursor of new organism. This process is slower than that of the cell division and production of progeny by the unicellular organisms. Thus reproduction is slower in multicellular organism this is the disadvantage in multicellular organisms.

Answer:

B. they reproduce slower than unicellular organisms

Answer:

700g

Explanation:

Given parameters:

Density of gasoline  = 0.7g/cm³

Volume of gasoline  = 1L  = 1000cm³  

Unknown:

Mass of the gasoline  = ?

Solution:

Density is the mass per unit volume of a substance. It can be expressed as;

 Density  = [tex]\frac{mass}{volume}[/tex]  

 So;

      Mass  = density x volume

    Mass  = 0.7 x 1000  = 700g

A molecule or ion that donates the hydrogen in a hydrogen bond is a hydrogen bond donor A molecule or ion that binds to this hydrogen is a hydrogen bond acceptor. Specify the hydrogen bonding behavior of the 4 species below by selecting: donor for species that act as donors only acceptor for species that act as acceptors only both for species that act as both donors and acceptors neither for species that act neither as donors nor as acceptors.

Answers

The question is incomplete, the complete question is found in the image attached.

Answer:

1- acceptor

2-donor

3-acceptor

4-donor

Explanation:

A hydrogen bond acceptor is a molecule that has an electronegative atom having a lone pair of electrons that participates in the hydrogen bond.

A hydrogen bond donor is the molecule that supplies the hydrogen atom of a hydrogen bond.

If we look at structure I-IV in the image attached, I and III are hydrogen bond acceptors because they all possess electronegative atoms having lone pairs of electrons but do not have hydrgen atoms bonded to highly electronegative atoms.

Similarly, structures II and IV are hydrogen bond donors. The C=C double bond is electron withdrawing and highly electronegative making the hydrogen atoms attached to it acidic and hydrogen bond donors. Also, nitrogen is an electronegative atom thereby making structure IV a hydrogen bond donor.

Answers

Answer:

A. This allows the plants to conserve water and not bloom during the heat of the day

Explanation:

Most desert plants only bloom at night because they take advantage of animals like moths and insects that fly at night for pollination and reproduction.

Because these plants are in the desert and do not get enough water except from short occasional rainfalls, they conserve water and not bloom during the heat of the day. They bloom at night when the temperature is low and this enhances their water conservation and survival.
