what is the chemical formula of Fire​

Answers

Answer 1

Answer:  

The heat of the flame will keep remaining fuel at ignition temperature. The flame ignites gases being emitted, and the fire spreads. As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat

Explanation:

Answer 2

Answer:

Chemical formula of fire is burning or combustion of air (particularly oxygen).

Given that nitrogen forms
three bonds with hydrogen to
make NH3, how many hydrogen
atoms do you think will bond
with an atom of phosphorous?

Answers

Answer:

Three

Explanation:

Nitrogen and phosphorus are on the same group in the periodic table. Elements in the same group have similar chemical properties. This is because of the number of valence electrons that they share among each other.

 The valence electrons are the outermost shell electrons found within an atom.

Nitrogen and phosphorus can both be found on the fifth group on the periodic table.

Their oxidation state is:

either 5 or 8-5  = 3

Since phosphorus bonds with 3 hydrogen atoms, nitrogen will also do the same.


How many moles of H 2 will I need to make 5 moles of NH3?
12 SSO

Answers

Answer:

7.5 moles of hydrogen is required

Explanation:

Given data:

Number of moles of H₂ needed = ?

Number of moles of NH₃ = 5 mol

Solution:

Chemical equation:

N₂ + 3H₂     →     2NH₃

Now we will compare the moles of ammonia and hydrogen.

         NH₃       :         H₂  

          2           :          3

          5           :         3/2×5 = 7.5 mol

Thus, 7.5 moles of hydrogen is required.

2 i think i am not very good at this lol

Explanation:

The units that acceleration use are distance/time^2  (in metric units).

The acceleration is the change of velocity over time, so

In another way, if the velocity is constant, the acceleration is zero, but if the velocity change over the time (as a car do when the red light change), the acceleration takes value!.

Which of the following atoms would have a charge of +1?
An atom with 9 protons, 9 electrons, and 9 neutrons
An atom with 7 protons, 11 electrons, and 8 neutrons
An atom with 5 protons, 5 electrons, and 4 neutrons.
An atom with 6 protons, 5 electrons, and 7 neutrons

Answers

Answer: An atom with 6 protons, 5 electrons, and 7 neutrons

Explanation: In this case, neutrons do not matter as they have a charge of 0, or no charge. A proton has a charge of +1 and an electron has a charge of -1. Since there are 6 protons, the total charge of the protons would be +6. Since there are 5 electrons the total charge of the electrons would be -5. +6 - 5 would result in a charge of +1. This means that this atom would have an overall charge of + 1. Basically, if there is one more proton than electron, then the overall charge of the atom will be +1 but if there is one more electron than proton, then the overall charge of the atom will be -1.

What is the formula unit of barium fluoride?

Answers

Answer: [tex]BaF_{2}[/tex]

Explanation: Because barium is in Group 2, it forms ions with a charge of +2. Fluorine, in Group 17, form ions with a charge of -1. Cross the charges to get the subscripts (Since Ba has a charge of +2, F has a subscript of 2. Because F has a charge of -1, Ba needs a subscript of 1). Therefore, a formula unit of the compound is [tex]BaF_{2}[/tex].

Calculate the sodium ion concentration when 70.0 mL of 3.0
M sodium carbonate is added to 30.0 mL of 1.0 M sodium
bicarbonate.

Answers

Answer:

4.5 M Na+

Explanation:

Multiply the molarity by the volume of the solution to get moles.

Note that there are TWO sodium ions in sodium carbonate, therefore the first-mole calculation must be multiplied by two.

Since molarity is defined as moles of ions/liters of solution, the final molarity will be the sum of the calculated moles divided by the sum of the liters of solution.

Distance of Proxima  Centauri = 4.242 light years

Find:

Distance in kilometre

Computation:

1 light year = 10,000,000,000,000 km

Answers

The percent by mass of Tin : = 27.08%

Further explanation

Given

25.00 g of the compound

6.77 g of Tin

18.23 g of Bromine

Required

The percent by mass of Tin

Solution

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements

%mass X = (mass X/mass sample) x 100%

So %mass of Tin :

= (6.77 g : 25 g) x 100%

= 27.08%

Explanation:

Answer:

D. silicon and oxygen

Explanation:

The most abundant elements on the earth's crust are silicon and oxygen. Silicon and oxygen forms a wide range of silicate minerals they are found in the crust.

There are many silicates which are derived from the basal units of silicon and oxygen combining together. Other atoms or elements then combines with the silicate framework.

Oxygen is about 46% abundant in the crust whereas silicon takes about 28% to be the second most abundant element on the crust.

Silicate minerals abounds in rocks and within the soil.
