Balance the following equation __N2+__O2→__N2O​

Chemistry
1 answer:
fenix001 [56]3 years ago
3 0

Answer:

2N₂   +  O₂  →  2N₂O

Explanation:

Given equation:

        N₂   +  O₂  →  N₂O

In balancing a chemical equation, the number of atoms on both sides of the expression must be the same.

To solve this problem, we use a simple mathematical approach;

  put coefficients a,b and c

             aN₂   +  bO₂  →  cN₂O  

Conserving N;

                   2a  = 2c

Conserving O:

                  2b  = c

 Let a = 1, c = 1 , b  = \frac{1}{2}

   multiply through by 4

           a = 2, b  = 1 and c  = 2

 Balanced equation is;

          2N₂   +  O₂  →  2N₂O

A 0.75M solution of CH3OH is prepared in 0.500 kg of water. How many moles of CH3OH are needed?
4vir4ik [10]

Answer:

We need 0.375 mol of CH3OH to prepare the solution

Explanation:

For the problem they give us the following data:

Solution concentration 0,75 M

Mass of Solvent is 0,5Kg

knowing that the density of water is 1g / mL,  we find the volume of water:

                           d = \frac{g}{mL} \\\\ V= \frac{g}{d}  = \frac{500g}{1 \frac{g}{mL} } = 500mL = 0,5 L

Now, find moles of CH_{3} OH are needed using the molarity equation:

                           M = \frac{ moles }{ V (L)} \\\\\\molesCH_{3}OH  = M . V(L) = 0,75 M . 0,5 L\\\\molesCH_{3}OH = 0,375 mol

therefore the solution is prepared using 0.5 L of H2O and 0.375 moles of CH3OH,  resulting in a concentration of 0,75M

If object A is placed on the pH scale at pH = 3 and object B is placed at pH = 8, which of the following must not be true?
ss7ja [257]
I believe the correct answer is D. Because object A on the pH scale reads pH=3. Which means it is more acidic in nature and thus possess a greater hydrogen or hydronium ion concentration than object B, which has a higher value on the pH scale. Object B would thus have a lower hydronium ion concentration than Object A.

A student uses a magnet to move a 0.0 25 KG metal ball the magnet exerts a force of five in which causes the body to begin movin
givi [52]

Answer:

The acceleration of the ball when it begins to move is 200 m/s²

Explanation:

The given parameters are;

The mass of the metal ball, m = 0.025 kg

The force exerted by the magnet on the ball, F = 5 N

From Newton's second law, F = m × a

Where;

a = The acceleration of the ball

Therefore, by substitution, we have;

5 = 0.025 × a

a = 5/0.025 = 200 m/s²

The acceleration of the ball when it begins to move = 200 m/s²
