Answer:

I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.

Answer:

A. write balanced chemical equation (including states), for this process.

Explanation:

Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air.  

Hydrocarbon combustions always involve  

[some hydrocarbon] + oxygen --> carbon dioxide + steam.  

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

Balance carbon, six on each side:  

C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

Balance hydrogen, six on each side:  

C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

Now, we have fifteen oxygens on the right and O2 on the left.  

Two ways to deal with that. We can use a fraction:  

C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

Or, if you prefer to have whole number coefficients, double everything  

to get rid of the fraction:  

2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

With the SATP states thrown in...  

C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

Answer:

the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atoms nucleus. the first element in a period of the periodic table introduces a new principal energy level.

Explanation:

the electrons surrounding an atom are located in region around the nucleus called "energy level".

Answer:

36 oxygen atoms

Explanation:

From the question given above, the following data were obtained:

Compound => 4Al₂(CO₃)₃

Number of Oxygen atom in the compound =?

The number of oxygen atom in the above compound can be obtained as follow:

4Al₂(CO₃)₃

Al = 4 × 2 = 8 atoms

C = 4 × 3 × 1 = 12 atoms

O = 4 × 3 × 3 = 36 atoms

From the simple illustration made above, there are 36 oxygen atoms in the compound.

Answer:

5446.8 J

Explanation:

From the question given above, the following data were obtained:

Mass (M) = 50 g

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Specific heat capacity (C) = 0.89 J/gºC

Heat (Q) required =?

Next, we shall determine the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 192.4 – 70

ΔT = 122.4 °C

Finally, we shall determine the heat required to heat up the block of aluminum as follow:

Mass (M) = 50 g

Specific heat capacity (C) = 0.89 J/gºC

Change in temperature (ΔT) = 122.4 °C

Heat (Q) required =?

Q = MCΔT

Q = 50 × 0.89 × 122.4

Q = 5446.8 J

Thus, the heat required to heat up the block of aluminum is 5446.8 J

Answer:

All of them have a nucleus..

Explanation:

Pretty simple stuff.  There's no cell without one.

Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.

Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.

The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.

Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).

Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

The upward drag and downward force is equal for the skydiver when he jumps down from the plane. Thus, he experiences a constant speed through out his motion.

Gravitational force is a kind of force by which a body attracts other objects into its center of mass. Force exerted by the body depends on the mass and distance to it.

Earth pull every objects into its surface by gravitational fore of attraction. For moving body the the gravitational force acting downward have an acceleration due to gravity.

The skydiver experiences a force upward by the drag of a the parachute. When this force becomes equal to the downward fore of gravity, then his speed will be constant thus, no gain or lose for speed.
