1. A baseball pitcher won 75% of the games he pitched. If he pitched 43 ballgames, how many games
kow [346]

Answer:

He won 32 games.

Explanation:

<em>Another way of expressing 75% is 75/100.</em>

To calculate how many games the baseball pitcher won, we <u>multiply the total of games played</u> (43, in this case) by the percent won:

43 * 75/100 = 32.25 ≅ 32

So the baseball pitcher won 32 games.

The equilibrium constant for the formation of ammonia from nitrogen and hydrogen is 1.6 x 102. What is the form of the equilibri
madam [21]

Answer:

First option:

[NH3]2  / [N2][H2]3

Explanation:

First of all we need to determine the reaction:

N₂(g) + 3H₂(g) → 2NH₃(g)

1 mol of nitrogen can combine with 3 moles of hydrogen to produce 2 moles of ammonia.

Remember that Kc has to involve Molar concentrations of products / reactants

Concentration must be elevated to the stoichiometry coefficient

Kc for the reaction is:  [NH₃]²  / [N₂] . [H₂]³

Electrons will readily tunnel out of the surface of a metal when a sufficiently high electric field E is applied to the surface.
puteri [66]

Answer:

1 that is 100%

Explanation:

here it is given that Fermi energy of the of the metal = 5 e.V

work function= 4 e.V

we have to find the probability that an incident electron will tunnel out if E=109 V/m

WORK FUNCTION : work function is defined as the energy required to withdraw an electron completely from the metal surface.

now the energy per unit volume in electric field is given by

E= \frac{1}{2}\times \varepsilon_0\times E^{2}

E=\frac{1}{2}\times 8.854\times 10^{-12}\times \left ( 10^{9} \right )^2

E=4.427\times 10^{6}joule

in electron volt E=4.427\times 10^{6}joule × 6.24\times 10^{18}

E=2.76\times 10^{25}e.V

hence the applied energy per unit volume is greater than the work work function of electron so there is probability of 100% that electron will tunnel out
