Answer: Yes, you are correct

Explanation: The smallest unit still water is the water molecule. A molecule of water can be divided into small parts, called atoms. This produces two atoms of hydrogen, and one atom of oxygen. However, those atoms alone do not have the properties of water.

Answer:

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.

Explanation:

Molarity : It is defined as the number of moles of solute present in one liter of solution. Mathematically written as:

$Molarity=\frac{\text{Moles of solute}}{\text{volume of solution in L}}$

Moles of citric acid = n

Volume of the citric acid solution = 125 mL =125 × 0.001 L= 0.125 L

(1 mL = 0.001L)

Molarity of the citric acid solution = 0.400 M

$0.400 M=\frac{n}{0.12 5L}$

n = 0.400 M × 0.125 L = 0.05 moles

Mass of 0.05 moles of citric acid :

$0.05 mol\times 192.12 g/mol=9.606 g$

9.606 grams of citric acid are present in 125 mL of a 0.400 M citric acid solution.

Why is U-235 the most common nuclear fuel instead of the more abundant U-238? State a clear topic sentence and support it with e

GREYUIT [131]

<h3>Answer and explanation;</h3>

The isotope U-235 is an important common nuclear fuel because under certain conditions it can readily be split, yielding a lot of energy. It is therefore said to be 'fissile' and use the expression 'nuclear fission'.
Uranium 238 on the other hand is not fissionable by thermal neutrons, but it can undergo fission from fast or high energy neutrons. Hence it is not fissile, but it is fissionable.
In a nuclear power station fissioning of uranium atoms replaces the burning of coal or gas. Heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.

dezoksy [38]

Answer:

0.218 M of Pb(NO3)2

Explanation:

Equation of the reaction

Pb(NO3)2(aq) + 2NaCl(aq) --> PbCl2(s) + 2NaNO3(aq)

1 mole of Pb(NO3)2 reacts to precipitate 1 mole of PbCl2

Molar mass of PbCl2 = 207 + (35.5*2)

= 278 g/mol

Number of moles of PbCl2 precipitated = mass/molar mass

= 12.11/278

= 0.04356 mol

Since 0.04356 moles of PbCl2 was precipitated, therefore by stoichiometry; 0.04356 moles of Pb(NO3)2 reacted.

Molarity is defined as the number of moles of solute in 1 liter of solution.

Molarity = number of moles/volumes

= 0.04356/0.2

= 0.218 M

What is the source of coal?

netineya [11]

Coal is a fossil fuel, formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.
