(CH3)2N2H2 + N2O4 → N2 + H2O + CO2 + heat [balance?]​

Chemistry

Rasek [7]3 years ago
7 0
<h3>Answer:</h3>

2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

<h3>Explanation:</h3>
  • Balancing chemical equations involves putting coefficients on reactants and products.
  • This results in an equal number of atoms of each element on either side of the equation.
  • Balancing chemical equations ensures that the law of conservation of mass is obeyed.
  • According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.
  • Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.
  • Therefore, the balanced equation would be;

       2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

If the density of a liquid 102g/cm^3, how many milligrams will be in 63 mL of that liquid?
Ede4ka [16]

Answer:

<h2>6426000 mg</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

63 mL = 63 cm³

We have

mass = 102 × 63 = 6426

But 1 g = 1000 mg

6426 g = 6426000 mg

We have the final answer as

<h3>6,426,000 mg</h3>

Hope this helps you

How do I find molar mass​
sergij07 [2.7K]

Answer:The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).

The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.

The radius of an atom is dependent upon which 2 things? (Two answers)
matrenka [14]

Answer:

The correct options are;

C. The magnitude of attraction from its nucleus

D. The distance between the electrons and its nucleus

Explanation:

The atomic radius reduces, within a given period, as we move from left to right, the number of protons increases alongside the number of electrons and the while the quantum shell to which the extra electrons are added to is the same. Therefore, the radius of the atom is dependent on the magnitude of the attraction from the nucleus

Similarly, as we progress to the next period, with an extra quantum shell, the atomic radius is seen to increase.

Therefore, the atomic radius is determined by the distance between the electrons and its nucleus.

Two methods by which we can conserve water and water the plants.
Natalka [10]

Answer:

Two methods which help us to conserve water are:

Sprinkler irrigation system: this irrigation has an arrangement of vertical pipes with rotating nozzles on the top. It is more useful in the uneven and sandy land where sufficient water is not available.

Drip irrigation system: this irrigation system has an arrangement of pipes or tubes with very small holes in them to water plants drop by drop just at the base of the root. It is very efficient as water is not wasted at all.
