Why do we get hot when we exercise?

It’s your body’s way of regulating your core temperature, preventing you from overheating. Your muscles heat up as they expend energy during exertion. When this happens, your skin begins to sweat, causing your body to cool down. The spike in your body heat also alerts your brain to ensure your body remains at the normal core temperature of 98.6 degrees Fahrenheit (or 37 degrees Celsius).

While exercising the body begins to warm up. When the body begins to warm up our muscles convert stored energy into heat energy, making our bodies become warmer. As the body heats up further the brains thermostat ensures that you remain close to the normal core temperature.

The equilibrium constant for the gas phase reaction

stellarik [79]

The equilibrium constant is found by [product]/[reactant]

If the equilibrium constant is very small, such as 4.20 * 10^-31, then that means at equilibrium there is very little product and a lot of reactant.
And likewise, if there is a lot of product formed, and very little reactant, then the K value will be very large, which tells us that it is predominantly product.

At equilibrium, for any reaction, there will always be some reactant and some product present. There cannot be zero reactant or zero product. Also keep in mind that the equilibrium constant is dependent on temperature.

At equilibrium, for your reaction, it is predominantly reactants.

A substance that can be broken down into simpler subtend only by a chemical change is aa. homogenous mixtureb. heterogeneous mix

Natasha2012 [34]

Answer:

d. compound

Explanation:

Mixture : It is defined as the substance that is made by the combination of two or more different components which are physically combined.

Homogeneous mixture are the mixtures in which the composition of the substances in it are uniformly mixed. Heterogeneous mixture are the mixtures in which the composition of the substances in it are not uniformly mixed.

Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass and are chemically bonded.

Element : It is a pure substance which is composed of atoms of similar elements.

As discussed above, The different elements in the compounds are chemically bonded and hence, it is the substance which can be broken down into the simpler units when it subtend only by the chemical change.
