After the first four games of a professional football season, three players scored a total of 80 touchdowns. Duke Johnson scored 14 of the touchdowns. Josh McCown scored 40% of the touchdowns. Andre Roberts scored the remaining touchdowns. How many touchdowns did Andre Roberts score?.

Answers

Answer 1

The number of touchdowns scored by Andre Roberts = 34 touchdowns

Given data :

Total number of touchdowns = 80

Number of players = 3

Determine the number of touchdowns scored by Andre Roberts

Player 1 ( Duke Johnson ) scored = 14

Player 2 ( Josh McCown ) scored = 40% of 80 = 32

∴  number of touchdowns scored by player 3 ( Andre )

  = 80 - ( 14 + 32 )

   = 80 - 46  = 34 touchdowns

Hence we can conclude that the number of touchdowns scored by Andre is 34 .

Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict.

Answers

Answer:

Thomson  placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery, minus the mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:

The cathode ray is composed of negatively-charged particles.

The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.

These subatomic particles can be found within atoms of all elements.

While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.

what is the mass of 3.0 x x times 10^23 atoms of neon?

Answers

Answer:

10.09 grams

Explanation:

First you need to know the number of moles you are dealing with.

If you know that each mole has 6.022x10²³ of something (in this case of atoms), you can divide 3x10²³ atoms of neons by 6.022x10²³ to obtain the number of moles.

You have 0.5 moles of Neon, so then by the periodic table, you see that the molar mass of neon is 20.18g/mol, so by each mole you have 20.18 grams of neon. Multiply 20.18 grams by 0.5 moles and you got 10.09 grams of Neon

Passing an electric current through a sample of water (H2O) can cause the water to decompose into hydrogen gas (H2) and oxygen gas (O2) according to the following equation. 2H2O Right arrow. 2H2 O2 The molar mass of H2O is 18. 01 g/mol. The molar mass of O2 is 32. 00 g/mol. What mass of H2O, in grams, must react to produce 50. 00 g of O2? 14. 07 23. 05 28. 14 56. 28.

Answers

The mass of water decomposed to produce 50 g oxygen has been 56.28 g. Thus, option D is correct.

The reaction for the decomposition of water has been:

[tex]\rm 2\;H_2O\;\rightarrow\;H_2\;+\;O_2[/tex]

From the balanced equation, 2 moles of water decomposes to form 1 moles of hydrogen and 1 mole of oxygen.

The mass of oxygen produced has been 50 g. The moles of oxygen has been given by:

[tex]\rm Moles=\dfrac{mass}{molar\;mass}[/tex]

The moles of oxygen has been:

[tex]\rm Moles_O_2=\dfrac{50}{32}\;mol\\Moles_O_2=1.5625\;mol[/tex]

The moles of oxygen produced has been 1.5625 mol.

The moles of hydrogen decomposed has been given from the balanced chemical equation as:

[tex]\rm 1 \;mole\;O_2=2\;mole\;H_2O\\1.5625\;mol\;O_2=1.5625\;\times\;2\;mol\;H_2O\\1.5625\;mol\;O_2=3.125\;mol\;H_2O[/tex]

The moles of hydrogen decomposes has been 3.125 mol.

The mass of hydrogen decomposed has been given by:

[tex]\rm Mass=moles\;times\;molar\;mass\\Mass_{H_2O}=3.125\;\times\;18.01\;g\\Mass_{H_2O}=56.28\;g[/tex]

The mass of water decomposed to produce 50 g oxygen has been 56.28 g. Thus, option D is correct.

Helppppp asaapppppp plzzzzzz

Answers

Answer:

Alright the very first thing you need to do is balance the equation:

2HCl + Na2CO3 -----> 2NaCl + CO2 + H2O

Now we need to find the limiting reactant by converting the volume to moles of both HCl and Na2CO3.

Volume x Concentration/molarity = moles

0.235L x 0.6 M = 0.141 moles / molar ratio of 2 = 0.0705 moles of HCl

0.094L x 0.75 M = 0.0705 moles /molar ratio of 1  = 0.0705 moles of Na2CO3

Since both of the moles are equal, it means the entire reaction is complete (while the identification of limiting reactant may seem like an unnecessary step, it's quite essential in stoichiometry, so keep an eye out) and there is no excess of any reactant.

Now we know that the product we want to calculate is aqueous so, following the law of conservation of mass, we should add both volumes together to calculate how much volume we could get for NaCl.

0.235 + 0.094 = 0.329L of NaCl

Now we apply the C1V1 = C2V2 equation using the concentration and volume of Na2CO3 because it's molar ratio is one to one to NaCl (You can also use HCL, but you have to divide their moles by 2 for the molar ratio)  and the volume we just calculated for NaCl.

(0.75M) x (0.094L) = C2 x (0.329L)

Rearrange equation to solve for C2:

(0.75M) x (0.094L)  =  C2

    (0.329L)

C2 = 0.214 M (Rounded)

When the reaction is finished, the NaCl solution will have a molarity concentration of 0.214 M.

Why are ionic compounds not considered to be molecules?

Answers

Answer:

No, ionic compounds are crystals of infinite cations and anions bound together. There is no “molecule” of ionic compounds such as, for example, NaCl, because there are no single units of the compound.

Explanation:

Ionic compounds are not considered to be molecules because they do not consist of discrete, covalently bonded units like molecules.

In ionic compounds, the bonding occurs through the transfer of electrons from one atom to another, resulting in the formation of ions. These ions are held together by strong electrostatic attractions, known as ionic bonds.

Unlike molecules, which are formed by the sharing of electrons in covalent bonds, ionic compounds do not have individual units with fixed numbers of atoms. Instead, they exist as a three-dimensional lattice structure composed of alternating positive and negative ions. The ions are arranged in a repeating pattern throughout the crystal lattice.

What is the purpose of the chemical ammonia (NH3) in hair dyes?

Answers

Answer: Ammonia, an alkaline chemical, is used to raise the pH level (it's levels of acidity) of our hair during the colouring process. This then lifts the cuticles of the hair fibre and allows the colour to be deposited onto the cortex (the inner part of the hair protected by the cuticles). In hair coloring products, ammonium hydroxide is used to support the lightening action of hydrogen peroxide and to prepare hair to accept color pigments. Alkaline properties of ammonia raise the cuticle and allow peroxide and dye molecules to penetrate the hair shaft. (creds to the internet)

Answers

Answer:

Answer temperatures gram is correct because there is more of a mass of numbers and the numbers are higher. (don't really know this subject, just guessing, hope this helped.)

The substance A has higher solubility then substance B because the higher the temperature the easier the substance will dissolve.

What is solubility?

The word solubility is defined as the ability of a substance, the solute, to form a solution with another substance, the solvent.

It can also be defined as a property that allow sugar molecule to dissolve.

It can be defined as at a given temperature, the amount of solute that can dissolve in a given amount of solvent.

In this reaction, increasing the pressure and temperature results in increased solubility. An increase in pressure causes more gas particles to enter the liquid, lowering the partial pressure.  

For exothermic reaction the temperature increases with decrease in solubility and for endothermic reaction the temperature decreases with increase in solubility.

Thus, the substance A has higher solubility then substance B because the higher the temperature the easier the substance will dissolve.
