Answer:

The following is a rather lengthy discussion on chemical stoichiometry, but it will lead you through the mole concept and its application to chemical reaction stoichiometry. The problems are different than the one posted, but if you can follow this, then you can work your problem of interest.

Explanation:

Stoichiometry is very easy to master if you understand the ‘mole concept’ and how it is used to define and describe chemical process mathematically. A ‘mole’ – in chemistry – is the mass of substance containing one Avogadro’s Number of particles. That is, N₀ = 6.023 x 10²³ particles / mole. When working with chemical reactions and equations data should be first converted to moles using the following conversions.  

1 mole = 1 formula weight = 6.023 x 10²³ particles = 22.4 liters at STP(0⁰, 1atm).

In this problem you are given the equation 2Na + 2H₂O => 2NaOH + H₂. ‘Reading the equation’ there are 2 moles of Na, 2 moles of water, 2 moles of NaOH and 1 mole of H₂. In another example 3H₂ + N₂ => 2NH₃ there are 3 moles of H₂, 1 mole of N₂ and 2 moles of NH₃. The mole values can be multiples or fractions but if one mole value increases all the remaining mole values increase or decrease proportionally. For example:

Using the equation 2Na + 2H₂O => 2NaOH + H₂, one could multiply the equation by 2 giving 4Na + 4H₂O => 4NaOH + 2H₂. The equation shows balance but is not in standard form. If one multiplies the equation by ½ gives Na + H₂ => NaOH + ½H₂. Again, the equation shows balance but is not in standard form.

Standard form of equation also implies the equation conditions are at 0⁰C & 1atm pressure and 1 mole of any gas phase substance occupies 22.4 Liters volume. Such is the significance of converting given data to moles as all other substance mass (in moles) are proportional.  

1st problem, 1.76 x 10²⁴ formula units of Na will react with water (usually read as an excess) to produce (?) grams of H₂.

1st write the equation followed by listing the givens below the respective formulas… That is…

                         Na                      +            H₂O       =>    NaOH    +    H₂,

Given:      1.76 x 10²⁴ atoms                excess             ---------          ? grams

               = 1.76 x 10²⁴atoms/6.023 x 10²³atoms/mole

               = 2.922moles                                        produces  =>    2.922moles H₂ (b/c coefficients of Na & H₂ are same)

                                                      Convert moles to grams =>    2.922moles H₂  x  2.000 grams H₂/mole H₂

                                                                                                              = 5.8443 grams H₂

2nd problem, 3.5 moles Na will react with H₂O (in excess) to produce (?) moles of NaOH.

Again, write equation and assign values to each formula unit in the equation.

                         Na                      +            H₂O        =>           NaOH    +    H₂,

Given:            3.5moles                       excess                      ? grams       ----

Since coefficients of balanced std equation are equal …

                      3.5 moles Na                          produces =>     3.5 moles NaOH

                                             Convert moles to grams =>     3.5 moles NaOH x 40 g Na/mole Na

                                                                                                  = 140 grams NaOH

3rd problem, 2.75 x 10²⁵ molecules H₂O will react with (?) atoms of Na.

Same procedure, convert to moles, solve problem by ratios then convert to needed dimension at end of problem.

                         Na          +            H₂O                                   =>           NaOH           +    H₂

Given:           excess            2.75 x 10²⁵ molecules H₂O    =>      ? atoms NaOH       ----

Convert to moles =>          2.75 x 10²⁵ molecules H₂O / 6.023 x 10²³ molecules H₂O/mole H₂O  

                                             = 45.658 moles H₂O              =>  45.658 moles NaOH  (coefficients are equal)

Convert moles NaOH to grams NaOH                            =>   45.658 moles NaOH x  40 grams NaOH/mole NaOH

                                                                                                     = 1826.33 grams NaOH  

Master the mole concept and you master a lot of chemistry! Good luck.

the balanced chemical equation was shown here :

2 K3PO4 (aq) +  3 NiBr2(aq)      ------------>>   Ni3(PO4)2 (s) +  6 KBr (aq)

The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:

2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6  KBr(aq)

Let's consider the unbalanced chemical equation that occurs when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide.

K₃PO₄(aq) + NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)

We will balance it using the trial and error method.

2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)

We will get the balanced equation by multiplying KBr by 6.

2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6  KBr(aq)

The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:

2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6  KBr(aq)

Answer: Hopefully this helps! sorry if not. :))

Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.

Answer:

Doubled.

Explanation:

The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:

That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.

Calcium nitrate, also called Norgessalpeter (Norwegian salpeter), is an inorganic compound with the formula Ca(NO3)2(H2O)x. The anhydrous compound, which is rarely encountered, absorbs moisture from the air to give the tetrahydrate. Both anhydrous and hydrated forms are colourless salts. Calcium nitrate is mainly used as a component in fertilizers, but it has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate.

Answer:

1.66 M

Explanation:

Molarity = moles/L solution

We have the following data:

mass NaCl = m = 63 g

volume of solution = V = 0.65 L

Thus, we first convert the mass to moles with the molar mass of NaCl (MM):

MM(NaCl) = 23 g/mol Na + 35.4 g/mol Cl = 58.4 g/mol

moles NaCl = m/MM = 63 g/(58.4 g/mol)= 1.08 mol

Finally, we divide the moles into the volume of solution to calculate the molarity:

M = moles NaCl/V = 1.66 mol/L

Fluorine will be most reactive with gold.

What is fluorine?

Of almost all of the elements, fluorine seems to be the most electronegative as well as reactive. Fluorine would be a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen would that be. It produces oxygen and even the incredibly corrosive hydrofluoric acid when it combines strongly with water.

Reactivity would be a substance's capacity to chemically combine with several other substances. Iron, for instance, reacts vigorously with oxygen.

As you move down the group, the halogens, which are non-metal elements in Group 7, become less reactive. In contrast to the alkali metals within Group 1 of the particular periodic table, this trend is the opposite. One of the most reactive elements in Group 7 was fluorine.

Kinetic energy is moving

Answer:

The correct answer is - Frequency is the number of wavelengths, which is measured in hertz.

Explanation:

Frequency is the number of waves that go through a fixed point at a particular time. Hertz is the SI unit for frequency which means that one hertz is equal to a unit number of waver passes in a unit time to a fixed point.

As the frequency of a wave increases which means the number of waves increases in the unit time, the shorter the wavelength will be.

a higher frequency wave has more energy than a lower frequency wave with the same amplitude.
