explain isotope with hydrgen diagram

Answers

Answer 1

Answer:

Hydrogen has three naturally occurringisotopes: 1H (protium), 2H (deuterium), and 3H (tritium). Other highly unstable nuclei (4H to 7H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope ofhydrogen is tritium, with a half-life of 12.32 years.

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

How many molecules of nitrogen dioxide (NO2) can be produced from 4 moles
of oxygen (O2)? *

Answers

The number of molecules of Nitrogen dioxide : = 4.816 x 10²⁴

Further explanation

Given

4 moles of Oxygen(O2)

Required

The number of molecules

Solution

Reaction

2NO + O2 ⇒ 2NO2

From the equation, mol NO2 :

= 2/1 x mol O2

= 2/1 x 4 moles

= 8 moles

The number of molecules :

= 8 x 6.02 x 10²³

= 4.816 x 10²⁴

List four rules for rounding numbers.

Answers

Answer:

the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30

Rounding fractions works exactly the same way as rounding whole numbers. The only difference is that instead of rounding to tens, hundreds, thousands, and so on, you round to tenths, hundredths, thousandths, and so on.

By rounding off, you could easily figure out that you would need about $6.00 to pay for your groceries.

A. doubles the rate

C. quadruples the rate
D. no effect on the rate​

Answers

C. quadruples the rate

Further explanation

Given

The rate law :

R=k[A]²

Required

The rate

Solution

There are several factors that influence reaction kinetics :  

1. Concentration   2. Surface area   3. Temperature   4. Catalyst   5. Pressure   6. Stirring  

The rate is proportional to the concentration.

If the concentration increased, the reaction rate will increase

The reaction is second-order overall(The exponent is 2)

The concentration of A is doubled, the reaction rate will increase :

r = k[A]² ⇒ r= k[2A]²⇒r=4k[A]²

The reaction rate will quadruple.

How many moles of H2S are produced?

Answers

Answer:

You can view more details on each measurement unit: molecular weight of H2S or grams This compound is also known as Hydrogen Sulfide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2S, or 34.08088 grams. Note that rounding errors may occur, so always check the results.

The number of grams that one "mole" of a substance weights is the definition of molar mass. So, the molar mass of H₂S is "34.08088"gams.

Molar mass:

In the definition of molar mass is the total atomic weights of the atoms that make up a molecule.Detailed information about each measurement unit can be found here: H₂S molecular weight in grams Hydrogen Sulfide is another name for this substance. A mole is the SI base unit for substance quantity. One mole of H₂S, or 34.08088 grams, is equal to one mole of H₂S.

How many moles of S2 are needed to produce 1.50 moles of SO2 gas

Answers

Answer:

1.5moles of S;

Explanation:

The reaction expression is given as:

            S +  O₂   →   SO₂

Number of moles of SO₂  = 1.5moles

From the balanced reaction expression:

              1 mole of SO₂ will be produced from 1 mole of S;

  So;      1.5moles of SO₂  will produce 1.5moles of S;

 

 

The moles of S₂ needed to produce 1.50 moles of SO₂ gas is 1.5 mol.

What are moles?

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

The reaction is

S +  O₂   →   SO₂

The number of moles of SO₂ is 1.50 mol

1 mole of S produce 1 mole of SO₂

Then, 1.5 mole of S will produce 1.5 SO₂

Thus, the moles are 1.5.

What would be the mass of 3 moles of water molecules?
a
54 grams
b 40 grams
C
30 grams
d 20 grams

Answers

Answer:

[tex]\boxed {\boxed {\sf A. \ 54 \ grams }}[/tex]

Explanation:

To convert from moles to grams, we must use the molar mass.

Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.

Hydrogen (H): 1.008 g/mol Oxygen (O): 15.999 g/mol

Now, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.

H₂O= 2(1.008 g/mol) + 15.999 g/mol = 18.015 g/mol

Use the molar mass as a ratio.

[tex]\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]

Multiply by the given number of moles.

[tex]3 \ mol \ H_2O*\frac{18.015 \ g \ H_2 O}{ 1 \ mol \ H_2 O}[/tex]

The moles of water will cancel.

[tex]3 *\frac{18.015 \ g \ H_2 O}{ 1 }[/tex]

[tex]3 *{18.015 \ g \ H_2 O}[/tex]

[tex]54.045 \ g \ H_2O[/tex]

Round to the nearest whole number. The 0 in the tenth place tells us to leave the number as is.

[tex]54 \ g \ H_2O[/tex]

There are about 54 grams of water in 3 moles.

Answer:

54 grams

Explanation:

First step is to find what one mole of water is in grams.

Water is H2O so that means we have two moles of Hydrogen.

H - 2 grams (on periodic table)

We have one mole of Oxygen.

O - 16 grams (on periodic table)

Add 2 and 16 to get 18 total grams in one molecule of H2O

Now multiply 3 times 18 to know how many grams in 3 moles of H2O

You end with

3x18=54 grams

O 0.208 mol B
0 7.53 x 1046 mol B
O 1.35 x 1025 mol B
0 4.82 mol B

Answers

Answer:

0.208 mol B

Explanation:

There are 6.02 × 10^23 atoms in one mole of a substance, according to Avagadro's law.

According to this question, there are 1.25 x 10^23 atoms of Boron. This means that the number of moles in the Boron atom can be calculated thus:

number of moles (n) = number of boron atoms (nA) ÷ Avagadro's number

n = 1.25 x 10^23 ÷ 6.02 × 10^23

n = 0.2076 × 10^(23-23)

n = 0.208 × 10^0

n = 0.208 × 1

n = 0.208 moles of Boron
