Answer:

In this cellular respiration process, some chemical bonds between atoms in oxygen and glucose molecules are broken. As atoms are rearranged, new chemical bonds are formed between different atoms to produce carbon dioxide gas and water. This process releases energy.

Answer:

observations (2), (3), and (4) provide strong evidence that a chemical reaction occurred.

Explanation:

Observations (2), (3), and (4) are evidence of a chemical reaction because a precipitate formed, energy was released (the bottom of the beaker felt warm), and bubbles were formed in the water. Observation (1) indicates a physical change, not a chemical reaction.

Answer:Ethyne

Explanation:

Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.

2-nonyne molecule is an alkyne. Hence, option B is correct.

Alkynes are groups of hydrocarbons that have the general formula of {Cn H2n - 2}. They have a triple carbon-to-carbon bond (C≡C) in their structure. Ethyne (HC≡CH) is the first member of the alkyne series.

Explanation:

Answer:

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Answer:

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Answer:

14.40g of H2

Explanation:

The balanced equation for the reaction is given below:

B2H6(g) + 6H2O(l) → 2H3BO3(s) + 6H2(g)

Next, we shall determine the mass of B2H6 that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:

Molar mass of B2H6 = (2x11) + (6x1) = 28g/mol

Mass of B2H6 from the balanced equation = 1 x 28 = 28g

Molar mass of H2 = 2x1 = 2g/mol

Mass of H2 from the balanced equation = 6 x 2 = 12g

From the balanced equation above,

28g of B2H6 reacted to produce 12g of H2.

Finally, we shall determine the mass of H2 produced when 33.61g of B2H6 reacted with excess water. This can be obtained as follow:

From the balanced equation above,

28g of B2H6 reacted to produce 12g of H2.

Therefore, 33.61g of B2H6 will react to produce = (33.61 x 12)/28 = 14.40g of H2.

Therefore, 14.40g of H2 were produced from the reaction.

Knowing the concentration of solutions is important in the real world for several reasons. Firstly, concentration provides information about the amount of solute present in a given volume of solvent, which is crucial for various scientific, industrial, and medical applications. Here's an example to illustrate the significance of concentration:

In the field of medicine, determining the concentration of drugs in pharmaceutical solutions is essential for accurate dosing and patient safety. Healthcare professionals need to know the concentration of active ingredients in medications to prescribe the appropriate dosage for patients. For instance, consider a situation where a doctor needs to administer a specific amount of a medication to a patient. Without knowing the concentration of the drug in the solution, it would be challenging to determine the correct volume of the solution needed to deliver the desired dosage. Incorrect concentrations or dosages can lead to ineffective treatment or even harmful side effects for the patient.

Additionally, concentration measurements play a vital role in environmental monitoring and analysis. For example, in water quality assessment, measuring the concentration of pollutants or dissolved substances in bodies of water helps identify potential contamination and evaluate the health of aquatic ecosystems. By monitoring the concentration of contaminants such as heavy metals or nutrients, environmental scientists can determine the impact on aquatic life and implement appropriate measures for pollution control and remediation.

Overall, understanding the concentration of solutions is crucial for a wide range of practical applications, including pharmaceuticals, environmental analysis, chemical manufacturing, food and beverage production, and many others. Accurate concentration measurements enable informed decision-making, quality control, and precise formulation, ensuring the effectiveness and safety of various products and processes in the real world.

1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.

2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.

3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.
