For each of the following unbalanced equations indicate how many moles of the second reactant would be required to react exalt with 0.275 mole of the first reactant. Balance the equation.Co(s) + P4 (s) Co3P2 (s)

Answers

Answer:

0.183 mol

Explanation:

so balenced equation is 6Co+4P=2(Co3P2)

so so the ratio is 6:4

so .275/6*4

=0.183 mol I think

The Answer will be:  0.183 mol

 so that the balanced equation is 6Co+4P=2(Co3P2) When the ratio is 6:4

       so that .275/6*4

      =0.183 mol.

When According to the A balanced chemical is equation has been equal numbers of atoms that are for each element they are involved in the reaction and its represented on the reactant and its product sides.Also that This is a better requirement that makes the equation must be satisfied and also that to be consistent with the law of conservation of the matter. then It may occur that it is confirmed by simply summing the numbers of atoms and also molecules on it either side of the arrow and it's comparing these sums to ensure that they are equal.

Answer: C excess reactant

Reason: It is not catalyst because catalyst are not consumed. It is not product because it was one of the reactants. It is not limiting because there was excess left over.

This means that the sodium bicarbonate in this experiment is the Excess reactant.

Answer:

Potassium (K) has 19 protons.

Each neutral atom of Potassium has 19 electrons.

Explanation:

A) Potassium has 19 protons because the atomic number tells us how many protons are in an atom of the element. (The atomic number is the number above the element symbol. For example, the number above "K" is 19, which is the atomic number).

B) If an atom is neutral, this means that the atom has neutral energy. Protons give positive energy and electrons give negative energy. For the atom to be neutral, the atom must have balanced energy, therefore, making the number of electrons equal to the number of protons in a neutral atom.

Which statement best distinguishes comets from nebulae? A. Nebulae can form stars, but comets cannot. B. Comets are in galaxies, but nebulae are not. C. Nebulae have moons. but comets do not. D. Comets can be part of a constellation, but nebulae cannot.

Answers

Answer: A-Nebulae can form stars, comets cannot

Explanation: Simply comets get destroyed and Nebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter, and eventually will become dense enough to form stars.

While Nebulae is a body of interstellar cloud, made of cosmic dust, hydrogen etc , Comets are balls of rocks, frozen gases, that revolve the Sun.

Nebulae can form stars, but comets cannot. Option A is correct

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:

Answers

Answer:

The concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.

Note: The question is incomplete. The complete question is as follows:

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature as follows:

3H2(g)+N2(g)⇌2NH3(g)

At equilibrium, the concentrations are

[H2] = 5.0 M, [N2] = 8.0 M, and [NH3] = 4.0 M.

What were the concentrations of nitrogen gas and hydrogen gas that were reacted initially?

Explanation:

Given the following data:

Concentration of H2 at equilibrium = 5.0 M

Concentration of N2 at equilibrium = 8.0 M

Concentration of NH3 at equilibrium = 4.0 M

The given equilibrium reaction is,

Initial                    a             b            c

Change                -3x          -x         +2x

Equilibrium         (a-3x)       (b-x)     +2x

The value of x is calculated from the equilibrium of NH3

Concentration of NH3 at equilibrium = 4.0 M  = 2x

x = 2.0 M

Substituting the value of x above

Initial Concentration of H2:

a - 3 × 2.0 M = 5.0 M

a = 6.0 M + 5 = 11.0 M

Initial Concentration of N2:

b - 2.0 M = 8 M

b = 8.0 M + 2.0 M

b = 10.0 M

Therefore, the concentration of nitrogen gas and hydrogen gas that reacted initially are 10.0 M and 11.0 M respectively.
