I've always been told that it's eight. This is only because the atom has to have the saem protons (positively charged) neutrons and electrons (negatively charged). However this does not occur with all atoms. :)

Every atoms which are not charged must have equal number of protons & electrons.

In short, Your Answer would be 8

A gas occupies 100.0 mL at a pressure of 780 mm ahh. What is the volume of the gas when it’s pressure is increased to 880 mm Hg

vlabodo [156]

Hello!

The volume of the gas when its pressure is increased to 880 mm Hg is 88,64 mL

This question can be easily answered using the Boyle's Law, which states that as pressure increases, the volume is lower. It can be expressed in a mathematical way as follows:

$P_1*V_1=P_2*V_2$

So, from this equation we can clear V₂ to find the volume at 880 mm Hg:

$V_2= \frac{P_1*V_1}{P_2}= \frac{780 mmHg*100 mL}{880 mmHg}=88,64 mL$

Have a nice day!

Titanium has five common isotopes: 46Ti (8.0%), 47Ti (7.8%), 48Ti (73.4%), 49Ti (5.5%), 50Ti (5.3%). What is the average atomic

NNADVOKAT [17]

Hey there!:

Isotopes : abundance :

46 Ti 8.0%

47 Ti 7.8 %

48 Ti 73.4 %

49 Ti 5.5 %

50 Ti 5.3 %

Weighted average = ∑ Wa * % / 100

Therefore:

( 46 * 8.0) + (47 * 7.8 ) + (48 * 73.4 ) + ( 49 * 5.5 ) + ( 50*5.3 ) / 100 =

4792.3 / 100

= 47.923 a.m.u

Hope that helps!

During which phase change does the entropy of a sample of H2O increase?

Bezzdna [24]

Answer: 3. H2O(l) -> H2O(g)

Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.
