How Do I Know The Number Of Molecules In A Equation

Answers

Answer 1

Answer:

Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.

Answers

Answer:

Photosynthesis utilizes water as an electron donor in cyanobacteria in general and creates oxygen as a by-product, although some can even use hydrogen sulfide, a process that occurs among other photosynthetic bacteria, such as purple sulfur bacteria. Carbon dioxide is reduced via the Calvin cycle to form carbohydrates.

- How many moles of S2 are needed to produce 1.50 moles of SO2 gas? S2 + 20, ----> 2802​

Answers

Answer:

0.75 moles

Explanation:

S2 + 2O2 = 2SO2

From the reaction above,

We see that number of moles attached to S2 is 1 and number of moles attached to SO2 is 2.

Since we want to find how many moles of S2 are needed to produce 1.50 moles of SO2 gas

The answer is gotten by proportion;

Number of moles = 1/2 × 1.5 = 0.75 moles

Jimmy's Chemical reaction/ Recipe for making Grilled chese sandwiches is given below: 1 slice of cheese + 2 slices of bread = 1 Grilled chese sandwich ( mole ratio is, 1:2:1) If Jimmy has the following amounts of ingredients (reactants/ reagents) : 10 slices of cheese 30 hslices of bread Answer the questions below in your submission: a) What is the limiting reagent/reactant? b) what is the excess reactant? c) True or false? The number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.

Answers

Answer:

See explanation

Explanation:

We have been told in the question that the equation of the reaction is; 1 slice of cheese + 2 slices of bread = 1 Grilled cheese sandwich ( mole ratio is, 1:2:1) .

Then the reagents are 10 slices of cheese 30 slices of bread. It then follows that 10 slices of cheese should be combined with 20 slices of bread according to the mole ratio.

However, we have 30 slices of bread and 10 slices of cheese so cheese is the limiting reactant while bread is the reactant in excess.

Yes, the number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.

Convert 3.01 x 1023 atoms CU to moles

Answers

The number of moles = 0.5

Further explanation

Given

3.01 x 10²³ atoms Cu

Required

moles

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Input the value :

n = N : No

n = 3.01 x 10²³ :  6.02.10²³

n = 0.5

Answers

Answer:

1.39  × 10²³ molecules  of CaCl₂

Explanation:

Given data:

Number of moles of CaCl₂ = 0.23 mol

Number of molecules = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

0.23 mol × 6.022 × 10²³ molecules  / 1mol

1.39  × 10²³ molecules  

How many kilo joules of heat are required to the decompost 1.96 mol Nah I 3(s)

Answers

Heat required = = 126.42 kJ

Further explanation

Given

1.96 mol NaHCO₃(s)

Required

Heat needed

Solution

Reaction( decomposition of Baking soda (NaHCO₃) :

2NaHCO₃ (s) + 129 kJ ⇒ Na₂CO₃ (s) + H₂O (g) + CO₂ (g)

For 2 mol NaHCO₃ , heat needed = 129 kJ

conversion factor :

[tex]\tt \dfrac{129~kJ}{2~mol}[/tex]

So for 1.96 mol :

= 1.96 mol x (129 kJ/2 mol)

= 126.42 kJ

Answers

Answer:

the remains of an animal or plant preserved within a layer of rock otherwise A.

A fossil is the remains of an animal or plant preserved within a layer of rock. The correct option is A.

What are fossils?

Fossils are the preserved form of animals or plants that are preserved on rocks or deep in the earth's crust and did not get damaged. They are discovered in the digs that are done by paleontologists.

The bones and sometimes dry skins and hairs, and teeth are also found that are preserved. These fossils help in studying animals and plants that were present in former times.

They do not get destroyed because they are preserved in rocks and stones. We got to know about dinosaurs by their fossils. There are different types of fossils are found.

Thus, the correct option is A. The remains of an animal or plant are preserved within a layer of rock.
