Answer:
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
Hope this helps you
(2) CH3CH2CH2CH3
(3) CH3CH2CH2COOH
(4) CH3CH2COOCH3
formula represents a hydrocarbon. Therefore, option (2) is correct.
Hydrocarbons are merely carbon and hydrogen. Aliphatic or aromatic. Aliphatic hydrocarbons are saturated or unsaturated open-chain hydrocarbons.Saturated aliphatic hydrocarbons have single bonds, while unsaturated ones have double or triple bonds.
Aromatic hydrocarbons have alternating double bonds in a ring.Only option 2——is a hydrocarbon. Butane, a saturated aliphatic hydrocarbon, with four carbon and 10 hydrogen atoms.

Given 44.8 liters of H₂ gas, 22.4 liters of O₂ gas would be required for a complete reaction, producing 44.8 liters of H₂O gas. This conclusion is reached by leveraging Avogadro's law, ideal gas law, and understanding stoichiometry.
The question involves understanding how standard molar volumes and stoichiometry play into gas reactions. Avogadro's law states that the volume of a gas is directly proportional to the number of moles of the gas. Therefore, if you have 44.8 liters of H₂ gas, complying with Avogadro's law and the given ratios of gases as stated in the problem, you can conclude that to react completely, you would need 22.4 liters of O₂ gas, producing a total of 44.8 liters of H₂O gas as per reaction stoichiometry.
Avogadro's law is critical to understanding gas behavior and stoichiometry. Equally, understanding the concept of the ideal gas law is necessary to perform stoichiometric calculations involving gaseous substances.
Dalton's law of partial pressures also plays into calculations involving gaseous mixtures and helps to understand how different gases within a mixture interact. Overall, comprehending these concepts grants insights into gas behavior under varying temperature, pressure, and volume conditions and how gases react in chemically balanced equations.

The scientists use one of their five senses to gather information, they are making an observation.
The active gathering of data from a primary source is observation. Observation of living things makes use of the senses. Using scientific tools to perceive and record data is another way that observation may be used in science.
A technique for gathering information through observation of individuals, situations, or physical qualities as they are occurring naturally.
Using one or more senses, our observational abilities provide us with knowledge about things, occasions, attitudes, and occurrences. Being able to see and learn about the outside world is crucial because it forms the basis of effective communication.
Thus, option A is correct.

In scientific endeavors, when one of the five senses is used to gather information, it constitutes making an observation. Observations can involve both qualitative and quantitative data, and they provide evidence that scientists use to form conclusions.
When scientists use one of their five senses to gather information, they are A. making an observation. Scientists usually perform observations by using one or more of their five senses to gain an understanding of the properties or behaviors of a substance or a system. These data can be qualitative (descriptive) or quantitative (consisting of numbers). For instance, seeing a plant growing (observation) and measuring its growth over weeks (data collection). From these observations, the scientist can infer conclusions based on the evidence collected. In brain studies, the activity in the brain during specific tasks is observed, which could be the basis for conclusions about brain functionality.

A balanced chemical equation shows that mass is not lost or gained in a chemical reaction by ensuring the number of atoms and overall charge on both the reactants and products side are equal, adhering to the law of conservation of mass.
A balanced chemical equation is one where the number of each type of atom in the reactants side is equivalent to the number of the same type of atoms in the products side. In chemical reactions, matter cannot be created or destroyed, a principle called the law of conservation of mass. This means that all the atoms present in the reactants will be accounted for in the products, ensuring that mass is never lost or gained during the reaction process.
For instance, if we take the simple chemical reaction of hydrogen and oxygen forming water (2H2 + O2 → 2H2O), you'll see that there are four hydrogen atoms and two oxygen atoms both before and after the reaction, thus demonstrating mass conservation. Additionally, in balanced chemical equations, not only should atoms be balanced, but also charges to ensure charge conservation which is necessary when dealing with ionic substances. The mass balance and charge balance are both instrumental in maintaining the law of conservation of mass in chemical reactions.
