Activation energy is required to start a reaction.

Answer: activation

<u>Explanation:</u>

Activation energy is the minimum energy the molecules required in order to collide with each other. Chemical reactions require a particular energy to start its function. The reaction only occurs when the products are more stable than the reactants.

This energy can be in the form of kinetic or potential energy. When the molecules collide, the molecules' kinetic energy used to stretch, sometimes bend and possibly break bonds, causing chemical reactions. Faster the objects move, more the kinetic energy it possesses.

What are the relationships between temperature and viscosity of water?
iris [78.8K]

Explanation:

Both cohesion and molecular interchange contribute to liquid viscosity. The impact of increasing the temperature of a liquid is to reduce the cohesive forces while simultaneously increasing the rate of molecular interchange. The former effect causes a decrease in the shear stress while the latter causes it to increase.

temperature?

The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly.

Based on the information given about capsules, which of the following types of molecules would you suspect comprises an S. pneum
Sergio039 [100]

"Polysaccharide carbohydrate" comprises an S. pneumoniae capsule.

<u>Option:</u> C

<u>Explanation:</u>

The lengthy sequences of carbohydrate molecules, primarily polymeric carbohydrates constructed of units of monosaccharides linked together through glycosidic connections, understood as Polysaccharides. This carbohydrate can respond to water by catalyzing amylase enzymes, which generate component sugars.

A major human pathogen is Streptococcus pneumoniae or pneumococcus. The virulence is primarily due to its polysaccharide envelope, which protects it from the recipient immune response, and this has led to comprehensive study of the shell.
