What is always true of a weak acid

Explain how a nuclear power plant functions and what safety precautions must be taken to ensure the safety of the power plant, i

Talja [164]

Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are important resources for a country’s energy mix, only nuclear power is capable of producing large amounts of electricity 24 hours a day, 365 days a year.

For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC), the U.S. Environmental Protection Agency and the U.S. departments of Energy and Transportation—establish radiation protection regulations for U.S. nuclear plants based on internationally recognized scientific studies.

For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas: reactor safety, radiation safety and security.

36.4 g of SnCl2 is dissolved in 135.7 mL of water.

Yuki888 [10]

Answers:

1st: 189.6 g/mol

2nd: 0.1357 L

3rd: 1.41 M

Explanation:

Finding Molar Mass:

SnCl2 = Tin(II) Chloride

Tin has a molar mass of 118.71 g/mol

Chloride has a molar mass of 35.453 g/mol

Chloride*2 = 70.906

118.71 + 70.906 ≈ 189.6 g/mol

Finding Liters of Solution:

L = mL/1000

135.7 mL / 1000 = 0.1357

Finding Molarity:

molarity = moles of solute / liters of solution

M = (36.4g / 189.6g) / 0.1357 L = 1.41 M

Hope this helped ;)

What is the ratio of molecules in: CH4 + 2O2 -> CO2 + 2H2O

nalin [4]

Answer:

1:2:1:2

Explanation:

A molecule is made up of aggregates of small particles called atoms.

CH₄ + 2O₂ → CO₂ + 2H₂O

From the reaction above we have: 1 molecule of methane CH₄ reacting with 2 molecules of oxygen gas O₂ to produce 1 molecule of carbon dioxide gas CO₂ and 2 molecules of H₂O:

CH₄ + 2O₂ → CO₂ + 2H₂O

1 : 2 : 1 : 2

How many grams of C12 can be prepared from the reaction of 16.0 g of MnO2 and 30.0 g of HCl according to the following chemical

kogti [31]

Answer:

Mass of Cl₂ produced 12.78 g

Explanation:

Given data:

Mass of MnO₂ = 16 g

Mass of HCl = 30.0 g

Mass of Cl₂ produced = ?

Solution:

Chemical equation:

MnO₂ + 4HCl → MnCl₂ + Cl₂ + 2H₂O

Number of moles of MnO₂:

Number of moles = mass / molar mass

Number of moles = 16 g/ 87 g/mol

Number of moles = 0.18 mol

Number of moles of HCl:

Number of moles = mass / molar mass

Number of moles = 30 g/ 36.46 g/mol

Number of moles = 0.82 mol

Now we will compare the moles of Cl₂ with MnO₂ and HCl.

MnO₂ : Cl₂

1 : 1

0.18 : 0.18

HCl : Cl₂

4 : 1

0.82 : 1/4×0.82 = 0.205 mol

The number of moles of Cl₂ formed by HCl are less it will limiting reactant.

Mass of Cl₂ formed:

Mass = number of moles × molar mass

Mass = 0.18 mol × 71 g/mol

Mass = 12.78 g

How many moles are in 7.12 x 10^21 atoms of iron?

devlian [24]

To Find :

How many moles are in $7.12 \times 10^{21}$ atoms of iron.

Given :

We know, 1 mole of any element or compound contains exactly $N_A$ ( Avogadro's Number ) atoms/compound .

Now, $N_A = 6.022 \times 10^{23}$

So, number of moles in given number of atoms are :

$n = \dfrac{6.022 \times 10^{23}}{7.12 \times 10^{21}}\\\\n = 1.18 \times 10^{-2} \ mol$

Hence, this is the required solution.
