oksano4ka [1.4K]

Answer:

hope this helps :)

Explanation:

for the first one, you can look at the periodic table and look at the atomic number and it will show you how many protons there are giving you the answer because protons and electrons are equal in a pure element

a- carbon

b- neon

c- boron

d- oxygen

e- helium

f- hydrogen

g- lithium

h- beryllium

i- nitrogen

1- sulfur

2- S

3- 16

4- 32.066

5- 16

6- 16

7- 16.066

8- draw circles and put 16 dots like on the other page and in the middle put 16 nuetrons and electrons

9- 6 i think

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, 1, m, and

babymother [125]

Answer:

The correct option is A) 3, 2, -2, -1/2.

Explanation:

Quantum numbers represent different properties regarding the level, sublevel and orbital in which an electron is. There are 4 quantum numbers:

Principal quantum number (n): indicates the level of energy and gives information about the size of an orbital. It can only take positive and integer values, e. g., 1, 2, 3...
Angular quantum number (l): indicates the sublevel of energy and provides information about the shape of the orbital. Some common shapes are spherical (l=0) and polar(l=1). Shapes for bigger l are more complicated. l values depend on n values. l values can be integers up to (n-1). For example. if n = 2, l can take the values 0 and 1.
Magnetic quantum number (m): it gives information about the orientation in space of an orbital. It may take any integer value between -l and +l. For example, if l = 1, m can take values -1, 0 and 1, each one referring to an orbital p along a different axis in the space (x, y and z axes).
Spin quantum number (ms): it refers to the spin angular momentum of an electron and it can take 2 values: -1/2 or +1/2.

A) 3, 2, -2, -1/2 is correct because it follows every rule.

B) 3, 3,-4, 1/2 is wrong because if n=3, l can only be up to 2, and l from -3 to +3.

C) 3,2,0,0 is wrong because ms cannot take the value 0.

D) 3,3,3, -1/2 is wrong because if n=3, l can only be up to 2.

E) 3, 4, 6, -1/2 is wrong because if n=3, l can only be up to 2, and l from -3 to +3.

8.) If 396 g of Carbon Dioxide (CO2) are produced, what mass of Oxygen

KengaRu [80]

Answer:

480 g of oxygen.

Explanation:

C3H8 + 5O2 ---> 3CO2 + 4H2O

Using the molar masses:

3*12 + 6*16 g of CO2 were formed from 10*16 g O2

132g g CO2 from 160 g O2

1g CO2 from (160/132) g O2

396 g from (160/132) * 396

= 480 g of oxygen.

A 100-gram sample of material requires 1220 calories of heat energy to raise its temperature from 20 0C to 80 0C. What is the sp

SashulF [63]

Taking into account the definition of calorimetry, sensible heat and latent heat, the specific heat capacity of the material is 0.203 $\frac{calories}{gC}$ .

<h3>Calorimetry</h3>

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

The amount of heat a body receives or transmits is determined by:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

<h3>Specific heat capacity of the material</h3>

In this case, you know:

Q= 1220 calories
c= ?
m= 100 g
ΔT=Tfinal - Tinitial= 80 C - 20 C= 60 C

Replacing in the definition of amount of heat:

1220 calories= c× 100 g× 60 C

Solving:

c= 1220 calories÷ (100 g× 60 C)

c= 0.203 $\frac{calories}{gC}$

Finally, the specific heat capacity of the material is 0.203 $\frac{calories}{gC}$ .

Explain how the folding of the mitochondrial inner membrane and the many individual chloroplast thylakoids are beneficial to a c

Mice21 [21]

Answer:

It allows for an increased exposed surface area and hence a faster rate of reaction between the reacting agents and the organelles.

Explanation:

Chemical reaction is dependent on the surface area of contact between the reacting parties. Having a folding surface as seen in many cell organelles gives an advantage of increasing the surface area available for contact between the reacting agent and the organelles. This ensures that reaction is faster and more effective.
