Answer:

There might be some problem in the engine's cooling system.

Explanation:

There are many reasons why your car could be overheating, but the basic process of overheating involves a problem with the vehicle's cooling system that doesn't allow heat to leave the engine compartment. This is often due to a leak or blockage somewhere in the engine cooling system or other components.

Answer:

Engines can overheat for many reasons. In general, it's because something's wrong within the cooling system and heat isn't able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.

1. What is the relationship between ecological succession and equlibrium in an ecosystem?

alexandr1967 [171]

Answer:

Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.

What is the majority of a solution that contains 0.55 mole of HCl in water to make 1.50 L HCl solution?

PSYCHO15rus [73]

Answer:

0.367M

Explanation:

Molarity refers to the molar concentration of a solution. It can be calculated using the formula below:

Molarity = n/V

Where;

n = number of moles (mol)

V = volume (L)

According to the given information in this question;

n = 0.55 mole

V = 1.50 L

Molarity = 0.55/1.50

Molarity = 0.367M

C2H4(g) + H2(g) → C2H6(g) ΔH = –137.5 kJ; ΔS = –120.5 J/K Calculate ΔG at 25 °C and determine whether the reaction is spontaneou

Katen [24]

Answer:-ΔG=-101.5KJ

Explanation:We have to calculate ΔG for the reaction so using the formula given in the equation we can calculate the \Delta G for the reaction.

We need to convert the unit ofΔS in terms of KJ/Kelvin as its value is given in terms of J/Kelvin

Also we need to convert the temperature in Kelvin as it is given in degree celsius.

$\Delta H=-137.5\\ \Delta S=-120J/K\\ \Delta S=-0.120KJ/K\\ T=25^{.C}\\ T=273+25=298 K\\ \Delta G=?\\ \Delta G=\Delta H-T\Delta S\\\Delta G=-137.5KJ-(278\times -0.120)\\ \Delta G=-137.5+35.76\\\Delta G=-101.74\\\Delta G=Negative$

After calculating forΔG we found that the value ofΔG is negative and its value is -101.74KJ

For a reaction to be spontaneous the value of \Delta G \ must be negative .

As the ΔG for the given reaction is is negative so the reaction will be spontaneous in nature.

In this reaction since the entropy of reaction is positive and hence when we increase the temperature term then the overall term TΔS would become more positive and hence the value of ΔG would be less negative .

Hence the value of ΔG would become more positive with the increase in temperature.

So we found the value of ΔG to be -101.74KJ

Why is Dalton's Gas Law a problem for people who visit high altitudes?

sergey [27]

Dalton’s law states that any given time the percentage of each of these (toxic?) gasses in the air we breathe it’s contribution.

People who ascend high altitudes experience Delton’s law when they try to breathe. Oxygen’s pressure decreases a total atmospheric pressure decreases in accordance with Dalton’s law.
