Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?
Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
A. 80
B. 140
C. 150
D. 75
Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.
What type of electron is available to form bonds?
Answer:
The electrons that are available to form bonds are known as valence electrons.
Explanation:
The electrons that are available to form bonds are known as valence electrons. I hope this answer is helpful.
The type of electron available to form bonds is a valence electron
What type of electron is available to form bonds?Valence electrons are the electrons in the outermost energy level or shell of an atom. These electrons are involved in the formation of chemical bonds between atoms.
Valence electrons are responsible for determining the chemical properties and reactivity of an element. When atoms come together to form chemical bonds, they do so by sharing, gaining, or losing valence electrons. The interaction of valence electrons between atoms allows for the formation of covalent bonds, ionic bonds, or metallic bonds, depending on the specific circumstances.
Therefore, valence electrons are crucial in the process of bonding between atoms.

Ivan reads a story about a population of mice that become stranded in a dark jungle. Some mice are dark brown, while others are white. According to the process of natural selection, predict which mice would be more successful living in a dark jungle. Explain natural selection and your prediction.
Answer:
The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.
The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.
What is natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

Answer:
Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.

A student wants to investigate the force of gravity. The student has an apple and a marble. What would be the best way for the student to use these materials? Place the apple on the floor. Roll the marble so it hits the apple. Put both objects on a desk. Push them forward at the same time. Hold both objects at the same height above the floor. Drop them at the same time. Place the marble on a desk. Place the apple next to the marble so the objects touch.
Answer:
Put both objects on a desk
Explanation:
The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.
According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.
Mathematically,
F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.
What are the reactants and products of the light independent reactions?
Answer:
In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.
The reactants and products of the light-dependent reactions of photosynthesis would be as follows:
Reactant: water, radiant energy, ADP, and NADP+
Products: oxygen gas, ATP, and NADPH
In the light reaction, radiant energy excites the electrons of chlorophyll molecules. The excitation causes the electrons to be knocked off the chlorophyll molecule and the energy of the electrons is used to convert ADP to ATP and NADP+ to NADPH.
The space left by the excited electrons is filled by electrons from water molecules with oxygen from the water molecule being released as a result.

Describe how water is important to plants in terms of:
i) making food in plants
ii) the plant's shape
iii) hydrolysis and dehydration
Answer:
i) In terms of food production in plants, water is essential to plants as it is the evaporation of water that occurs in leaves that allows carbon dioxide to enter and to begin photosynthesis.
(ii) In terms of the shape of the plant, water is important to plants as the hydration of the cells of a plant allows the cell walls to retain their shape and thus give structure to the plant.
(iii) In terms of hydrolysis and dehydration, water is essential for plants because water is not a photosynthesis reactant or respiratory product.
Explanation:
i) Water is important in terms of making food in plants:
Water is required for the germination of seeds and as soon as growth starts water serves as a carrier in the distribution of mineral nutrients and plant food.
ii) Water is important in terms of the plant's shape:
Responsible for turgor pressure in cells (Like air in an inflated balloon, water is responsible for the fullness and firmness of plant tissue. Turgor is needed to maintain cell shape and ensure cell growth.)
iii) Water is important in terms of hydrolysis and dehydration:
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen.
The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas.
