The right answer is water.

A condensation reaction can sometimes release as a product a molecule of water. We sometimes speak of synthesis by dehydration. This is, for example, the case for two monosaccharides, such as glucose or fructose, which can condense into a disaccharide (sucrose) via dehydration synthesis. The reverse reaction is then hydrolysis, the water recombining with the two hydroxyl groups, the disaccharide being converted back into two monosaccharides.

The substance that would be added in order to reverse the reaction would be any substance that is found in the product side. Adding a substance that tends to be a product will shift the equilibrium of the system and will allow the reaction to produce the substances that is found in the reactant side.

Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates

mestny [16]

Answer and Explanation:

Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.

It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.

Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.

In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.

Alika [10]

The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.

<h3>What is metallic bond?</h3>

Metallic bond is a form of chemical bond or force of electrostatic attractions that exist between the positively charged metal ions which give room for conduction of electricity or heat.

This type of bond only occur in metallic substances or objects alone. This is characterized by high boiling and melting points.

Therefore, The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.

AveGali [126]

<span>On a modern firearm, the feature that functions like the lock on a muzzleloader is the safety. The safety was added to modern guns to prevent them from accidentally firing, although it should be noted that a safety is a man-made mechanical device which makes it subject to failure at times.</span>
