Answer:
The smallest possible inside length of the tank is
m.
Explanation:
As we know that

Thus, volume of
liter tank is also equal to
cubic meter
The volume of a cube is equal to
, where, x is the length of the side of the cube
With the give condition,
Solving the above equation, we get -

The smallest possible inside length of the tank is
m.

Answer:
The white powder is sodium carbonate
Explanation:
If you supposed an ammount of 100 grams of the white powder, it means there are 42.59 grams of Na, 12.02 grams of C and 44.99 grams of O. If you divided every compound by its molar mass, you will know the moles of every compound. (According to moles=mass (grams)/ molar mass (grams/mole)
C=12.01 g/mole, Na=23 g/mole, O=16 g/mole
So:
C=12.02/12.01= 1.0 moles, Na=42.59/ 23= 1.85 moles, O= 44.99/16= 2.81 moles
Knowing this, we can stimated that the white powder has 1 mol of C and approximately 2 and 3 moles of N and O, respectively
Chemical formula for sodium carbonate is Na2CO3 and the formula for sodium oxalate is Na2C2O4. So the white powder is Na2CO3
Answer:
5.418x10^24 atoms
Explanation:
1mole of a substance contains 6.02x10^23 atoms.
From the above, it means that 1mole of NH4CN contains 6.02x10^23 atoms.
Therefore, 9 moles of NH4CN will contain = 9 x 6.02x10^23 = 5.418x10^24 atoms
<u>Answer:</u> The chemical equation is written below.
<u>Explanation:</u>
Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

The chemical equation for the combustion of ethyl chloride follows:

We are given:
When 4 moles of ethyl chloride is burnt, 5145 kJ of heat is released.
For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.

For an exothermic reaction, heat is getting released during a chemical reaction and is written on the product side

So, the chemical equation follows:

Hence, the chemical equation is written above.
