What happens when you put one hand in ice water and the other in warm water
NikAS [45]

When you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

<h3>What is thermal adaptation?</h3>

The ability of a body to adjust to temperature is called thermal adaptation. Mammals are the animals who can adjust the temperature of their body.

The reptiles are not able to adjust their body temperature, because they are poikilothermic. They have to take the help of outer environment to adjust their body temperature.

Thus, when you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

Write the balanced equation and determine the information requested in each of the following.
Elena L [17]

Answer:

See explanation.

Explanation:

Hello!

In this case, we can proceed as follows:

1. Here, the undergoing chemical reaction is:

C_2H_2+\frac{5}{2} O_2\rightarrow 2CO_2+H_2O

Thus, the moles and mass of water turn out:

n_{H_2O}=20.0kgC_2H_2*\frac{1000gC_2H_2}{1kgC_2H_2} *\frac{1molC_2H_2}{26.04gC_2H_2} *\frac{1molH_2O}{1molC_2H_2}=768molH_2O\\\\m_{H_2O}=768molH_2O*\frac{18.02gH_2O}{1molH_2O}=13,840 gH_2O

2. Here, the undergoing chemical reaction is:

CaCO_3+2HCl\rightarrow CaCl_2+H_2O+CO_2

So the required moles of HCl and the yielded of water are:

n_{CaCO_3}=2.6molHCl*\frac{1molCaCO_3}{2molHCl}=1.3molCaCO_3\\\\ n_{H_2O}=2.6molHCl*\frac{1molH_2O}{2molHCl}=1.3molH_2O

3. Here, the undergoing chemical reaction is:

Al_2O_3+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2O

Now, we apply each mole ratio obtain:

A.

n_{H_2SO_4}=2.6molAl_2O_3*\frac{3molH_2SO_4}{1molAl_2O_3} =7.8molH_2SO_4

B.

n_{Al_2(SO_4)_3}=2.6molAl_2O_3*\frac{1molAl_2(SO_4)_3}{1molAl_2O_3} =2.6molAl_2(SO_4)_3

Best regards!
