"how many atoms are in 169 g of calcium"

Chemistry
1 answer:
den301095 [7]3 years ago
4 0

First calculate the number of moles. Molar mass of Calcium = 40.08 g/mol

 

Number of moles = 169 g / (40.08 g / mol) = 4.217 moles

 

Using Avogadros number, we can get the number of atoms:

<span>Number of atoms = 4.217 moles * (6.022 x 10^23 atoms / moles) = 2.54 x 10^24 atoms</span>

A balloon is filled with 35.0 L of helium in the morning when the temperature is 35.00 oC.
nexus9112 [7]

Answer: V = 33.9 L

Explanation: We will use Charles Law to solve for the new volume.

Charles Law is expressed in the following formula. Temperatures must be converted in Kelvin.

V1 / T1 = V2 / T2 then derive for V2

V2 = V1 T2 / T1

= 35 L ( 308 K ) / 318 K

= 33.9 L

A positively charged substance is brought near the ion. What will most likely happen and why
d1i1m1o1n [39]

<u>Answer:</u> It repels positive ion and attracts negative ion.

<u>Explanation:</u>

There are 2 types of ions:

1. Cations: These ions are positively charged ions which are formed when a substance looses electrons.

2. Anions: These ions are negatively charged ions which are formed when a substance gains electrons.

It is known that, like charges repel each other and unlike charges attract each other.

As, it is given that the substance is positively charged, so it will attract anion and repel cation.
