How many atoms are in this formula PCl6 ?

Chemistry
1 answer:
Debora [2.8K]2 years ago
4 0

The molecule is unstable and impossible to create the PCl_6

Only one way is that change the formula

  • PCl_6-

Lets look at structure(See attachment)

There are total 7atoms

  • P=1
  • Cl=6

Why is an alloy is often more useful than a pure metal
mrs_skeptik [129]
<h2>Answer:</h2>

A pure metal has specific properties. Sometimes we need that metal but with modified properties. So for the modification of properties we make alloys.

<h3>Explanation;</h3>
  • An alloy is a mixture of two elements, one of which is a metal.
  • Alloys often have properties that are different to the metals they contain.
  • This makes them more useful than the pure metals alone.
  • For example, alloys are often harder than the metal they contain.

A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a <em>high</em> tide.

The gravitational attraction of the Moon and the inertia of the oceans cause <em>two tidal bulges </em>on opposite sides of the Earth.

B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.

C. True. The whole solar system moves around the galaxy.

D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.

E. False. The <em>mass of an object is constant</em>, but its <em>weight changes</em> according to the gravity of the planet.

F. False. To find the mass of an object, <em>divide</em> its weight by gravity.

F = mg  or weight = mass × gravity

∴ <em>Mass = weight/gravity </em>

The elementary reaction 2H2O(g)↽−−⇀2H2(g)+O2(g) 2H2O(g)↽−−⇀2H2(g)+O2(g) proceeds at a certain temperature until the partial pres

Answer:

6.25\times 10^{-6} is the value of the equilibrium constant at this temperature.

Explanation:

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures  of reactants each raised to the power equal to their stoichiometric ratios. It is expressed as K_{p}

2H_2O(g)\rightleftharpoons 2H_2(g)+O_2(g)

Partial pressures at equilibrium:

p^o_{H_2O}=0.070 atm

p^o_{H_2}=0.0035 atm

p^o_{O_2}=0.0025 atm

The equilibrium constant in terms of pressures is given as:

K_p=\frac{(p^o_{H_2})^2\times (p^o_{O_2})}{(p^o_{H_2O})62}

K_p=\frac{(0.0035 atm)^2\times 0.0025 atm}{(0.070 atm)^2}=6.25\times 10^{-6}

6.25\times 10^{-6} is the value of the equilibrium constant at this temperature.

Answer:

reactive nonmetals since they have a full valence shell (that's why they're stable).
