_N2 + _H2 = _NH3
Will there be any leftover reactants left?
(Kinda urgent)
Answer:
This reaction is the synthesis of Ammonia using Nitrogen and Hydrogen gas.
N+H→NH3
We must remember that Nitrogen and Hydrogen are both diatomic molecules in their standard gas form. This adjusts the equation to
N2+H2→NH3
Now we need to adjust coefficients in order to balance the atoms on each side of the equation. Currently, we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.
We can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.
N2+3H2→2NH3
This gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

I hope this was helpful.

Answer:
Balance the equation N2 + H2 ⇒ NH3
Balancing chemical equations is usually easier than it looks
There are 2 Nitrogens and 2 Hydrogens on the left side
There are 1 Nitrogen and 3 Hydrogens on the right side
Hydrogen seems to be the more complicated term so we should start with that
_N2 + _H2 ⇒ _NH3
With 2 H on one side and 3 on the other, our common multiple is 6
To balance the H we need to multiply H2 by 3 and NH3 by 2
_N2 + 3H2 ⇒ 2NH3
Now that we have H balanced, we need to look at N
There are 2 Nitrogens on both sides of the equation, so in this case, it is done

Why is it important to know the temperature of the water when dealing with ions in
an aqueous solution?
Water does not ionize at higher temperatures.
Water becomes very acidic when at low temperatures.
Temperature affects the concentration of water.
The ionization constant of water is usually given at 25 °C.
Water at a higher temperature will produce more ions than water at a lower temperature.
Answer:
temperature affects the concentration of water

If you have 3.4grams of carbon how many
moles of carbon would you have?
Answer:
3 moles of carbon atoms is equivalent to 36 gm carbon.
In 12gm carbon there are 6.023*10^23 atoms.
So in 36 gm there are 3*6.023*10^23 atoms.
so the answer is 18.069*10^23 atoms.
Explanation:
Explanation:
moles = mass in gm/ molar mass =3.4/12= 17/60

Based on the initial and final temperatures of the mixture in degrees Celsius shown in the diagram above the laboratory setup, what is the calculated ΔT of the water reported to the appropriate number of significant figures?
what are the characteristics of temperature
A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. It measures the average kinetic energy of the substances also.
The average kinetic energy of the particles in an object is measured by its temperature. The velocity of these particles likewise increases as the temperature rises. A thermometer or a calorimeter is used to determine the temperature.
Our weather is made up of several various elements, including temperature, cloudiness, wind speed, and the quantity and type of moisture in the air.
Thus temperature determines the weather and kinetic energy.

Which of the following atoms has the largest atomic radius and explain why: potassium, gallium, or germanium.
Answer:
Potassium
Explanation:
The atom with the largest atomic radius is potassium from the given list.
The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between nuclei in the solid metal state.
Across a period in the periodic table, atomic radii decreases progressively from left to right.
This is due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
Answer:
Potassium
Explanation:
An atom's size is defined by the distance from the nucleus to the valence (outer) shell of electrons. Although difficult to to actually measure, due to electrons existing in a probability field with no defined boundaries, it is common knowledge that the more valence shells of an atom, the larger the atom.
Knowing this, lets look at the electron configuration of the elements mentioned:Oxygen = 2,6Sodium = 2,8,1Magnesium = 2,8,2Potassium = 2,8,8,2As we can see, only Potassium has four electron shells, therefore Potassium has the largest atomic size.Alternatively, one can look at a Van der Waal radii table to find that the radii of the four elements are (in picometres):Oxygen = 152 pmSodium = 227 pmMagnesium = 173 pm
Showing once again how Potassium has the largest atomic radius, and therefore the largest atomic size. Interestingly enough, Sodium has a larger atomic radius then magnesium, despite having less electrons and protons.
Which are not combination reactions?
Check all that apply.
A. 2H2O + 2H2 + O2
B. H2 + Cl2 → 2HCI
C. Fe + MgO + Mg + FeO
D. 2Na + Cl2 → 2NaCl
Answer:
A and c
Explanation:
In A the product is added to the reactant, so the real reaction is (2H2O = 2H2+O2).
In B hydrogen and clorine are combined to give hydrochloric acid and 2 is used to balance the reaction in the product, so it's a combination reaction .
In C the case is similar to A , so the real reaction is (Fe+MgO = Mg + FeO ) this is displacement reaction where a more reactive element takes place of a less reactive element .
In D sodium reacting with Chlorine to give sodium chloride ,so we conclude that it's a combination reaction .

What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.
Answer: Fish
Explanation:
Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.
