What element was used to make the first atomic bomb

Answers

Answer 1

Answer: The element was uranium, it was made during World War II ( the first atomic bomb was dropped on Japan, Hiroshima )
For more information, a H-bomb ( Hydrogen bomb ) is more explosive ( the sun is made mostly by Hydrogen ) and North Korea declared that they just have one.

Which of these statements about mixtures is true?Mixtures are made up of elements bonded together.
Elements and compounds are types of mixtures.
Pure substances are made up of mixtures combined in specific ratios.
Mixtures are classified based on the distribution of particles in them.

Answers

Answer: Option (d) is the correct answer.

Explanation:

When two or more different substances are mixed together then it results in the formation of a mixture.

Mixture are of two types, that is, homogeneous mixture and heterogeneous mixture.

In homogeneous mixture, the constituent particles are distributed evenly throughout the mixture.

Whereas in heterogeneous mixture, the constituent particles are non-uniformly distributed.

Thus, we can conclude that mixtures are classified based on the distribution of particles in them.

The best answer from the choices would be the last option. Mixtures are classified based on the distribution of particles in them. The classification are called homogeneous and heterogeneous mixtures. The former type describes a mixture where all components are distributed evenly. The latter type is a mixture where the components do not have uniformity in the mixture.

How many mL of 0.100 m NaHCO3 are needed to prepare 750.0ml of a 0.0500 m NAHCo3 solution

Answers

Following the rule of thumb in dilution, the equation that can be used to solve this problem is:

C1V1 = C2V2

where:
C1 = concentration of solution 1
V1 = volume of solution 1
C2 = concentration of solution 2
V2 = volume of solution 2

(0.1)(V1) = (0.05)(750)
V1 = 375 mL

This shows that 375 mL of a 0.1 m NaHCO3 solution is needed in order to dilute it to a 0.05 m NaHCO3 solution of 750 mL.

The percent by mass of carbon in HC2H3O2 is equal to__.

Answers

The percent mass of carbon is found by dividing the total mass of the carbon in the compound by the total mass of the compound itself. The mass of the compound is found by adding the molecular masses of the elements. The mas of the compund is 60 grams/mole. There are two Carbon atoms in the compound and each Carbon atom weighs 12 grams/mole, so two Carbon atoms weigh 24 grams/mole. The percent by mass of Carbon is (24grams/mole) divided by (60 grams/mole) times 100 which is equal to 40%. The correct answer is 40%.

Final answer:

The percent by mass of carbon in acetic acid (HC2H3O2) is calculated using the molar masses of its constituent elements. Upon calculation, it is determined that the percent by mass of carbon in acetic acid is 40.00%.

Explanation:

To calculate the percent by mass of carbon in acetic acid (HC2H3O2), we need to use the molar masses of the elements involved. The formula for acetic acid includes two carbon atoms, four hydrogen atoms, and two oxygen atoms. Using the given molar masses (carbon: 12.01 g/mol, hydrogen: 1.008 g/mol, oxygen: 16.00 g/mol), the molar mass of acetic acid can be calculated as follows:

Carbon: 2 × 12.01 g/mol = 24.02 g/mol
Hydrogen: 4 × 1.008 g/mol = 4.032 g/mol
Oxygen: 2 × 16.00 g/mol = 32.00 g/mol

Adding these together gives the molar mass of acetic acid as 60.052 g/mol.

To find the percent by mass of carbon, we take the total mass of carbon in the compound and divide it by the total molar mass of the compound:

(24.02 g/mol / 60.052 g/mol) × 100% = 40.00%

Therefore, the percent by mass of carbon in acetic acid is 40.00%.

46 What occurs at one of the electrodes in both an electrolytic cell and a voltaic ccl1?( I) Oxidation occurs as electrons arc gained at the cathode.
(2) Oxidation occurs as electrons are lost at the anode.(3) Reduction occurs as electrons are gained at the anode.
(4) Reduction occurs as electrons are lost at the cathode.

Answers

Oxidation occurs as electrons are lost at the anode at one of the electrodes in both an electrolytic cell and a voltaic cell. The answer is number 2. The rest of the choices does not answer the question given above.
