Water has a higher SHC as it would be cooler than the sand meaning it requires more energy to reach the same temperature 
emmainna [20.7K]3 years ago
7 0

Answer:

The sand has a higher specific heat

Explanation:

The answer is that the sand would have a higher specific heat than water because water requires a lot of heat to raise its temperature while sand needs less heat to change it as water has a high heat capacity that allows it to maintain its temperature within a range.

The force that holds protons together is called...?
Jobisdone [24]

Answer: Answer is in Explanation

Explanation:

The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

Write the Rate Law
Ivanshal [37]

As we know that rate law expression is

r = k { |a| }^{2}  { |b| }^{2}

(a)

r = k { |o2| }^{1}  { |no2| }^{2}

(b)

r = k { |cl2| }^{1}

(c)

r = k { |chcl3|}^{1}  { |cl2| }^{1}

How many grams are in 3.00 moles of carbon
sergiy2304 [10]

Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams

This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.

hope this helps have a awesome night/day❤️✨

the vapor pressure of a naqueous solution is found to be 24.9 mmgh at 25C. what is the mole fraction of solute in this solution?
Gekata [30.6K]

Answer:

Mole fraction of solute is 0.0462

Explanation:

To solve this we use the colligative property of lowering vapor pressure.

First of all, we search for vapor pressure of pure water at 25°C  = 23.8 Torr

Now, we convert the Torr to mmHg. Ratio is 1:1, so 23.8 Torr is 23.8 mmHg.

Formula for lowering vapor pressure is:

ΔP = P° . Xm

Where ΔP = P' (Vapor pressure of solution) - P° (Vapor pressure of pure solvent)

Xm = mole fraction

24.9 mmHg - 23.8 mmHg = 23mmHg . Xm

Xm = (24.9 mmHg - 23.8 mmHg) /  23mmHg

Xm = 0.0462
