1. How many grams of aluminum oxide can be formed by the reaction of 38.8 g of aluminum with
oxygen?
4 Al (8) + 3 O2(g) →2 A12O(s)
Answer: 50. 4g
Explanation:
First calculate number of moles of aluminium in 38.8g
Moles = 38.8g/ 26.982mol/g
= 1.44mol
By looking at the balance equation you can see that 4 moles of aluminium produce 2 moles of aluminium oxide.
4 = 2
1.4 = x
Find the value of x
x= (1.4×2)/4= 0.72 mol
0.72 moles of aluminium oxide are produced from 38.8g of aluminium
Now find the mass of aluminium produced.
Mass = moles × molar mass
= 0.72mol × 69.93 mol/g
= 50.4g

Identical twins are born with black hair. They grow up together as children, but as adults they live far apart and lead very different lives. How do you explain why one of the twin's black hair turns gray over time?
Answer:
Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. ... As identical twins get older they may look more and more different, because they are exposed to more diverse environments. The science of epigenetics explains how these environmental influences can affect the genes.
hope this is helpful!
The color changes occurs in hair might caused by life styles and diet irrespective of the genetical traits. The damaged pigment cells causes the gray hair.
What are genetic traits ?Each characteristics in a living thing is coded by genes in them. These codes corresponding to some behaviors are called genetic traits. The pigment melamine make the hair black.
Variation in the pigment makes the color variation in hair also. Gray hair may appear on anyone at any age. Some people begin to go grey as early as when they are in high school or college.
Our genes decide when we begin to grey our hair. That a result, the majority of us will start ageing at around the same time as our parents or grandparents did.
However, our lifestyle and diet also influence the hair and skin color. Therefore, there might have differences in appearance of twins too.

1- What do greenhouse gases do in our atmosphere? a. They absorb radiation given off by the Earth b They block harmful radiation from reaching the Earth c .They keep all the air within the Earth d .They make the Earth cooler
Answer: A. They absorb radiation given off by the earth.
Explanation: Green house gases are gases that have the capability of trapping the heat energy from the sun in our environment. These special attribute of these gases is what keeps our environment warm and sustain life as we know it. Example of Green House Gases include: carbon dioxide, water vapour and methane.
Answer:
A. THEY ABSORBS RADIATION GIVEN OFF BY THE EARTH.
Explanation:
Greenhouse gases are gases capable of absorbing and emitting infrared radiations in different wavelength range emitted by the earth. These gases include water vapor, carbon iv oxide, methane, ozone, chlorofluorocarbons, nitric oxide, hydrofluorocarbons. These gases contribute to the greenhouse effects and there actions are dependence on their respective characteristics, abundance in the atmosphere and the indirect effects it causes. Earth surfaces absorbs radiant energy from the sun and these radiations are reflected as light or reflected back to space as hear. Greenhouse gases are involved in absorbing and emitting these incoming energies in order to create a balance between the incoming and outgoing energies. This determines the temperature on the earth surface. The earth can be warm or cold depending on the direction the difference in this balance shifts. Without the greenhouse gases the average temperature of the earth will be lower than the expected temperature.

Answer:
Explanation:
The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.
Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly. idk if this helped*

Given the equation representing a chemical reaction at equilibrium in a sealed, rigid container:when the concentration of h2(g) is increased by adding more hydrogen gas to the container at constant temperature, the equilibrium shifts
Answer:
The equilibrium shifts to the right, shifting towards the products, thereby favouring forward reaction, leading to the production of more product (NH₃) and a reduction in the rate of backward reaction, resulting in a decrease in the production of reactant N₂ in the reaction.
Explanation:
Complete Question
Given the equation representing a chemical reaction at equilibrium in a sealed, rigid container:
N₂ (g) + H₂ (g) ⇌ NH₃ (g)
When the concentration of H₂(g) is increased by adding more hydrogen gas to the container at constant temperature, the equilibrium shifts
Solution
Le Chatelier's Principle explains the behaviour of the equilibrium in response to disturbances in properties for chemical reactions.
The principle states that, if the concentration, temperature and/or pressure of a chemical reaction at equilibrium is changed, the equilibrium position shifts to remedy this changes.
So, for a chemical reaction at equilibrium, provided that the other factors such as temperature and pressure remain constant, if more reactants are added (more H₂ is pumped into the reacting container), the equilibrium responds by shifting to the right, shifting towards the products, thereby favouring forward reaction, leading to the production of more product (NH₃) and a reduction in the rate of backward reaction, resulting in a decrease in the production of reactant N₂ in the reaction.

A balloon occupies a volume of 44 L at 200K, what will the temperature of the balloon become if it is changed to 500K?
Answer:
110L
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 44L
Initial temperature (T1) = 200K
Final temperature (T2) = 500K
Final volume (V2) =..?
The new volume of the balloon can be obtained by using Charles' law equation as shown below:
V1/T1 = V2/T2
44/200 = V2/500
Cross multiply
200 x V2 = 44 x 500
Divide both side by 200
V2 = 44 x 500/200
V2 = 110L
Therefore, the new volume of the balloon is 110L

How does mass defect relate to binding energy in the nucleus?
A.They both represent uncertainty in mass and energy measurements.
B. The mass defect represents the mass converted to binding energy
C. The binding energy replaces the missing mass during a reaction
D. The mass defect and the binding energy measure weak nuclear forces
Answer:
B. The mass defect represents the mass converted to binding energy.
Explanation:
I just took a quiz on a pe x and it was correct! :)
Relation of mass defect to binding energy in the nucleus expresses by the statement that the mass defect represents the mass converted to binding energy.
What is mass defect?Mass defect is the difference in the mass which is obtained by the difference between the total mass of nucleus and sum of the mass of the constituent particles of nucleus.
Binding energy is the amount of energy which is released dueing the formation of the nucleus of any any element and this energy is released because of the presence of the mass defect of nucleus.
Binding energy is directly proportional to the mass defect and calculated as:
B.E. = mc, where
m = mass defect
c = speed of light
Hence, mass defect represents the mass converted to binding energy.

"Calculate the amount of energy transferred if only 650.50 grams of sulfur trioxide (SO3) gas were produced. (Remember the ∆H = -396.8 kJ is part of the balanced equation)"
balanced equation: 2 SO2 (g) + O2(g) ⇌ 2 SO3 (g) ∆H = -396.8 kJ
Answer:
1.6×10^3 KJ
Explanation:
We must first calculate the number of moles corresponding to 650.50g of sulphur trioxide.
Number of moles = mass of sulphur trioxide/ molar mass of sulphur trioxide
Molar mass of sulphur trioxide= 80.066 g/mol
Given mass of sulphur trioxide= 650.50g
Number of moles = 650.50g / 80.066 g/mol
Number of moles = 8.124 moles of sulphur trioxide
Now from the balanced reaction equation;
Formation of 2 moles of sulphur trioxide evolves 396.8KJ of energy.
Therefore formation of 8.124 moles of sulphur trioxide will evolve;
8.124moles × 396.8 KJ /2 moles = 1611.8KJ or 1.6×10^3 KJ

☆CHEERS!☆At midday (12pm, Noon), what is happening in the leaf of a plant?
A) Cellular Respiration
B) Photosynthesis
C) Mainly photosynthesis and some cellular respiration
D) None of the above
Answer:
C
Explanation:
Noon is the peak amount of sun shining. Therefore the plant will be carrying out a lot of photosynthesis using the light. Cellular respiration happens regularly as well
At midday, what is happening in the leaf of a plant would be photosynthesis and cellular respiration. The correct option would, therefore, be C.
Photosynthesis has two reactions:
Light dependent reactionLight independent reactionThe light dependent reaction is rate determining step of photosynthesis. Hence, photosynthesis proceeds at normal rate during the day.
Cellular respiration, on the other hand, takes place with or without light.
Hence, at 12 pm, Noon, both photosynthesis and cellular respiration will be taking place simultaneously in the leaf of plants.
