It is really easy if you look up an electron configuration table (one that looks like a periodic table) and then just go down the rows left to right, top to bottom, and just stop when you get to where the element is on the table.

$1s^2 2s^2 2p^{6} 3s^2 3p^6 4s^2 3d^1^0 4p^3$

Slicing an average loaf of bread gives 13 medium thickness slices. Each slice of bread is to be coated with 0.0500 oz of mayonna

AlexFokin [52]

Answer:

36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.

Explanation:

Number of slices of ham = 231

Given that each sandwich has 1 slice of ham.

Then 231 slices of ham will be in :

$1\times 231 =231 sandwiches$

A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :

$231\times 2=462$

Each bread slice is applied with 0.0500 ounce of mayonnaise.

Then 462 bread slices will have :

$462\times 0.0500 ounces=18.48 Oz$

1 bread loaf = 13 bread slices

Then breads loves in 462 bread slices :

$\frac{462}{13}=35.54\approx 36$

36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.

A sample of helium gas in a balloon is compressed from 4.0 L to 3.2 L at a constant temperature. If the pressure of the gas in t

vampirchik [111]

Answer:

286 kPa

Explanation:

Boyles law states that volume of gas is inversely proportional to pressure o gas for a fixed amount of gas at constant temperature

P1V1 = P2V2

where P1 is pressure and V1 is volume at first instance

P2 is pressure and V2 is volume at the second instance

substituting the values in the equation

229 kPa x 4.0 L = P2 x 3.2 L

P2 = 286.25 kPa

the new pressure is 286 kPa

If it requires 18.2 milliliters of 0.45 molar barium hydroxide to neutralize 38.5 milliliters of nitric acid, solve for the mola

Ghella [55]

Hi! :)

Ba(OH)2 + 2 HNO3 → Ba(NO3)2 + 2 H2O

(18.2 mL) x (0.45 M Ba(OH)2) x (2 mol HNO3 / 1 mol Ba(OH)2) / (38.5 mL HNO3) = 0.43 M HNO3
