Answer:

2/6

Explanation:

In a balanced chemical equation as:

aA + bB → cC + dD

Where coefficients of reaction relates the number of moles of substances that are involved in the reaction. In the reaction:

Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH₃(g)

Per mole of Mg₃N₂(s) and per 6 moles of H₂O you will produce 3 moles of Mg(OH)₂(s) and 2 moles of NH₃(g).

To convert moles of H₂O to moles of NH₃ you can use:

X moles of H₂O ₓ (2 moles NH₃ / 6 moles of H₂O)

That means conversion factor to convert the number of moles of water to number of moles of ammonia is <em>2/6</em>.

<em>-It is important to say that obtention of conversion factor requires, in the first, the balanced chemical equation-</em>

I hope it helps!

write chemical equations of photosynthesis and cellular respiration and show if carbon is oxidized or reduced
irina [24]

Answer:

Explanation:

  • The chemical reaction for cellular respiration  is as follows -

C₆H₁₂O₆ ( Glucose ) + 6 O₂ ( Oxygen ) --------------> 6CO₂  ( Carbon dioxide ) +  6H₂O ( Water ) + 38 ATP molecules ( Energy ) .

This is an example of oxidation of carbon .

  • The chemical reaction for photosynthesis  is as follows -

6CO₂  ( Carbon dioxide ) + 6H₂O ( Water ) --------------> C₆H₁₂O₆( Glucose ) + 6 O₂  ( Oxygen ).

This is an example of reduction of carbon .

Some commercially available algaecides for swimming pools claim to contain 7% copper. Could the method used in this experiment t
AleksandrR [38]

Answer:

Explanation:

  1. 7% copper implies 7 w/v%(weight/volume %) of copper. This implies a 100 mL algaecide arrangement contains 7 grams of copper.  
  2. Henceforth we have a thought of the measure of copper that ought to be available in a given example of algaecide.  
  3. Indeed, even a 1 mL algaecide test is sufficient to discover the percentage of copper in it.  
  4. so a 25mL sample of algaecide must have around 1.75g of copper.

Pls, Help!!!!!!!
yKpoI14uk [10]

Answer:

Element A = Oxygen

Element H =

Element B = Aluminum

Element J = Magnesium

Element C = Selenium

Element L = Carbon

Element D = Sodium

Element Q = Francium

Element F = Antimony

Element R = Calcium

Element G = Chlorine

Element S = Tellurium

Explanation:

Element A  is Oxygen because: oxygen 6 valence electrons ; is a gas at room temperature ; and is transported in blood to cells.

Element H  is Neon because: Neon is a noble gas ;   qppears as red light when charged with  electricity (Neon light signs)  and it has the second highest Ionization energy of the elements

Element B  is Aluminum because: Aluminum is a metal and its ion has charge of +3. It is also located on the borders of the Metalloid staircase .

Element J  is Magnesium because its ion has charge of 2+ and is  isoelectronic with Neon  because it loses two electrons to now have 10 electrons.

Element C  is Selenium because its ion that has a charge of -2  is formed by gaining two electrons in order to have 36 electrons which is isoelectronic with Kr ypton

Element L  is Carbon because carbon has the smallest atomic radius of any member in the Carbon family  because it is the first member of the family and atomic radius increases on going down the group.

Element D  is Sodium because its ion has charge of +1  and it has 2 inner core levels , the 1 and 2 energy levels.

Element Q  is Francium because it has the largest radius and lowest ionization  energy of any element

Element F  is Antimony. It is a member of Nitrogen family  and has the second highest ionization energy level in family .

Element R  is calcium because its on has charge of +2  which is isoelectronic with Argon . Calcium also has atomic radius is larger than Ar gon.

Element G  is Chlorine. It has the second to the smallest radius of elements in the 3rd period  as the second to the last element in the period because atomic radius decreases across a period from left to right.

Element S  is Tellurium. It has atomic mass larger than Iodine just to the right  of it and is found in the 5th period

The vapor pressure of methanol is 143 mmhg. identify the best reason to explain why methanol spontaneously evaporates in open ai
goldfiish [28.3K]

Answer/Explanation:

Methanol has a molecular weight (32.04 g/mol), low-boiling point and because of its low boiling point, methanol readily evaporates at room temperature.

Under these specified non-standard conditions, the partial pressure of methanol is lower than its vapor pressure and this explains the reason for the spontaneous evaporation exhibited by methanol.

Which of the following natural resources cant be reused
ohaa [14]
Hi there! Air and sunlight can definitely be reused. Those are abundant and renewable resources. Therefore, A and D are eliminated. There is a limited amount of water, however, it's impossible to run out of it to the point that there's no more on Earth. C is out. The only answer choice that makes sense is coal, because it's a nonrenewable resource, and it takes millions of years to make more of. It's a fossil fuel, so once we use them up, we can't get anymore during our lives. The answer is B: coal.
