The energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant; option D.

<h3>What is energy?</h3>

Energy is the ability to do work.

Energy generating plants may either use wind, water or solar energy to produce electrical energy.

The most abundant source of energy from a reservoir is hydroelectric power plant.

Therefore, the energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant.

In conclusion, hydroelectric power plants are reservoirs of abundant energy supply.

The number of electrons (e- ) is
levacccp [35]

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Calculate the mass in grams of hydrogen chloride produced when 5.15 l of molecular hydrogen measured at stp reacts with an exces
navik [9.2K]

Answer: 17.9 g


Explanation:


1) Chemical equation:


H₂ (g) + Cl₂ (g) → 2HCl (g)


2) mole ratios:


1 mol H₂ : 1 mol Cl₂ : 2 mol HCl


3) Since, the pressure and temperature conditions do not change, the same proportion is valid for the volumes. Then:


1 liter H₂ / 2 liter HCl = 5.15 liter H₂ / x


⇒ x = 5.5 × 2 / 1 = 11 liter HCl


4) Calculate the number of moles of HCl in 11 liter of HCl at STP


At STP, 1 mol of gas = 22.4 liter


⇒ 11 liter × 1mol / 22.4 liter = 0.491 mol HCl


5) Use the molar mass to convert 0.491 mol to grams


molar mass of HCl = 1.008 g/mol + 35.453 g/mol = 36.461 g/mol


mass in grams = nuumber of moles × molar mass = 36.461 g/mol × 0.491 mol = 17.90 g.

Write an expression for the equilibrium constant of each chemical equation: a. SbCl5(g)SbCl5(g) + Cl2(g) b. 2 BrNO(g)2 NO(g) + B
denis-greek [22]

Answer:

See explanation

Explanation:

Step 1: Data given

For the reaction aA + bB ⇆ cC + dD

Kc = [C]^c * [D]^d / [A]^a [B]^b

a. SbCl5(g) ⇄ SbCl3(g) + Cl2(g)

Kc = [Cl2]*[SbCl3] / [SbCl5]

b. 2 BrNO(g) ⇄ 2NO(g) + Br2(g)

Kc = [Br2]*[NO]² / [BrNO]²

c. CH4(g) + 2 H2S(g) ⇄ CS2(g) + 4 H2(g)

Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]

d. 2CO(g) + O2(g) ⇄ 2CO2(g)

Kc =  [CO2]² / [O2][CO]²

Ede4ka [16]
Density = mass/volume
substituting the given values :
We get :
D = 37.4 / 2.2 x 10^3
D = 0.017 grams/liter

Explain why it is not possible to determine the type of Atom by simplifying knowing how many neutrons it has.
alexdok [17]

Answer:

It is not possible to accurately identify an element given only the number of neutrons. All atoms are made of three particles: electrons, protons and neutrons. The number of electrons is equal to the number of protons if the atom is uncharged.
