How does electron repulsion determine molecular shape?
NARA [144]
The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. ... The shape of a molecule is determined by the location of the nuclei and its electrons

if your hot pack requires 3.0g of a solid to obtain the correct temperature change, instead of the correct amount (1.4g) calcula
gregori [183]

114.3%

Explanation:

Given parameters:

True amount of solid = 1.4g

Measured amount  = 3.0g

Unknown:

Percentage error = ?

Solution:

The inaccuracy in the reading is termed uncertainty.

This is the error.

 Error  = true  value - measured value.

   The values of errors are absolute.

Percentage error = \frac{|true value - measured value|}{true value}  x 100

Percentage error = \frac{1.4 - 3}{1.4} x 100 = 114.3%

This is large amount of error

Chemistry help please! I just need to make sure the answers correct.... Thank you!
Veronika [31]
1. At constant tempaerature and pressure, 3 tablets produce 600cm^3 of gas
Thus calculating for 1 tablet that produces 600 / 3 = 200 cm^3
So now two tablets produce 200 x 2 = 400 cm^3
2. We have the equation PV = nRT, n being the number of moles
Pressure P = 1,000 kPa
Volume V = 3 L
R = 8.31 L kPa/mol-K
Temperature T = 298 K
n = PV / RT = (1000 x 3) / (8.31 x 298) = 3000 / 2476.38 = 1.21 moles
Number of moles = 1.21 moles.

How many neutrons and protons en all of them? HELP ASAP!!
RUDIKE [14]

You need to look at the Periodic table. The atomic number is the number of protons. When you subtract the atomic number from the mass number, you get the number of neutrons. i.e. for Beryllium (Be) the atomic number is 4, so it has 3 protons. Its atomic mass about 9, so 9-4=5. Therefore, there are 5 neutrons.
