What is the IUPAC name for H2O?
Answer:
I guess it is.....
Oxidane.
Answer:
Technically, dihydrogen monoxide.
Explanation:
You see, the International Union of Pure and Applied Chemistry, also known as IUPAC, hasn't seen a need to define a structural name for water yet.
Following the naming conventions, it should most likely be called "dihydrogen monoxide", but IUPAC has never officially defined this as the chemical name for water.
i really need help:/ my friend is helping and nobody understands it
Answer:
A= Compound
B= Mixture
C= Element
D= Element
Explanation:
A has two different types of atoms chemically together as a compound
B is made up of two or more different atoms not chemically joined together
C has one type of atom
D has one type of molecule. They're the same and could be a diatomic element like hydrogen

Two plants growing close to one another are competing for resources. Which resource are they NOT likely to compete for? Choices A-Water B-Soil and nutrients C- Carbon dixoide
Answer: the resource which they are not likely to compete for is CARBONDIOXIDE. The correct option is C.
Explanation:
Competition may be defined as the a negative effect on plant growth which occurs when there is reduction in the availability of resources.
During the growth of plants, there are several resources that affects it's growth and maintenance. These resources include:
--> soil nutrients,
--> water,
--> carbondioxide and
--> sunlight
Since plants are autotrophs, that is, they manufacture their own food through the use of inorganic raw materials such as water and carbondioxide in the presence of sunlight, there may exist some level of competition for these resources when there is lack of space.
But plants are NOT likely to compete for carbondioxide because the atmospheric pool of carbondioxide is large and well mixed, therefore it won't be affected by lack of space between the two plants. Unlike the other main resources such as soil nutrients and water which are highly competed for and can determine the distribution of plants in an ecosystem.

Which statement is correct about the law of conservation of energy?
Energy is created when water freezes.
Energy is destroyed when sugar is burned.
Energy stays inside molecules permanently.
Energy is transferred when atoms are rearranged.
Answer:
Energy is transferred when atoms are rearranged
Explanation:
Breaking bonds between atoms need energy. When new bonds are formed, energy is released
The law of conservation of energy is energy isn't created or destroyed
A and B are wrong because there is creation or destruction of energy
C is wrong because energy can be transferred (think touching a hot stove with your finger. heat is transferred from the stove to your finger OUCH!)
D is correct because the energy is still there, but in a different form

Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g

Which statement describes the reaction involved in cellular respiration?
A. Sugar is produced and stored until it is needed for energy.
B. CO2 is removed from the atmosphere, and O2 is released into the
atmosphere.
C. It is a redox reaction in which energy is released to ATP molecules.
D. O2 is removed from the atmosphere, and CO2 is released into the
atmosphere.
Answer:
C
Explanation:
Cellular respiration is the metabolic process and is a reduction-oxidation reaction that yields ATP molecules. Thus, option C is accurate.
What is cellular respiration?It is a redox reaction that utilizes glucose and oxygen molecules to release carbon dioxide and energy in the form of ATP. This energy released is used to drive the functions and roles of the cells.
The food molecule, glucose is broken in the presence of the oxygen molecule to release the carbon dioxide and the energy from the cells that are in the form of adenosine triphosphate molecule.
Therefore, option C. cellular respiration is a redox reaction is correct.

A piece of indium with a mass of 21.93 g is submerged in 46.3 cm3 of water in a graduated cylinder. The water level increases to 49.3 cm3. The correct value for the density of indium measured in g/cm3 from these data is:
Answer:
We know that,
Density= mass upon volume.
mass= 21.93g
Volume= 49.3 - 46.3
= 3 cm³
Density = 21.93÷ 3
= 7.31 g/cm³
Hope it helps :))
A piece of indium with a mass of 21.93 g is submerged in 46.3 cm³ of water in a graduated cylinder. The water level increases to 49.3 cm³. The correct value for the density of indium measured in g/cm3 from these data is 7.31 g/cm³.
What is density?The density of a material is defined as its mass per unit volume. Although the Roman letter D can also be used, the most common symbol for density becomes. Mathematically, density is calculated by dividing weight by volume.
Density is frequently loosely defined as weight per unit volume, which is technically wrong; this quantity is actually more accurately characterized as specific weight. One example is the oil and gas industry in the United States.
Density= mass/volume.
mass= 21.93g
Volume= 49.3 - 46.3
= 3 cm³
Density = 21.93÷ 3
= 7.31 g/cm³
Therefore, 7.31 g/cm³ is the density.

Is the equation for reaction 1 balanced? Explain your reasoning. If the reaction is not balanced, then state how you would balance it. Then, provide the balanced equation.
Answer:
Reaction is already balanced
Explanation:
The equation in reaction 1 is given as;
CH3COOH + NaHCO3 --> CO2 + H2O + Na+ + CH3COO-
The reaction is already balanced. This is because the umber of atoms of elements in the reactant is equal to that of the products
Carbon
Reactant = 2 + 1 = 3
Product = 2 + 2 = 3
Hydrogen
Reactant = 3 + 1 + 1 = 5

Question please
Answer:
See detailed explanation.
Explanation:
Hello!
i. In this case, since the given chemical reaction is exothermic due to the negative change in the enthalpy of reaction, we infer that according to the mentioned principle, by lowering the temperature the reaction will shift rightwards and therefore the yield is increased; thus, you need a lower temperature than the specified.
ii. In this case, since the reaction has less moles at the products side, according to the mentioned principle it'd be necessary to rise the pressure in order to increase the yield, since the increase of pressure favors the reaction side with the fewest number of moles.
