Answer:

27°C

Explanation:

q = 1500 J

m = 50g

c = 4.18 J/g°C

q = m·c·ΔT

ΔT = \frac{1500J}{50g*4.18\frac{J}{gC} } = 7C

ΔT = final temperature - initial temperature

Final temp = 20 + 7 = 27°C

How does the VSEPR theory explain molecular shape
natulia [17]

Answer:

to VSEPR theory, the shape of a molecule is related to the organization of the central atom's valence shell electrons. The valence shell electrons are all negatively charged and therefore are constantly repelling each other. This repulsion is what gives a molecule its three-dimensional shape.

1) How many moles are in 4.0x10^24 atoms?
-Dominant- [34]

Answer:

<h2>6.64 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{4 \times  {10}^{24} }{6.02 \times  {10}^{23} }   \\  = 6.644518...

We have the final answer as

<h3>6.64 moles</h3>

Hope this helps you
