Convert 125 g to kilograms

Chemistry
2 answers:
zmey [24]3 years ago

You can solve this using simple math.

One kilogram is equal to 1000 grams. All you have to do is divide 125 grams by 1000 grams to get x / 1 = x where x = the number of kilograms.
If you do this correctly, you should have 0.125 kilograms = 125 grams.

I hope this helps and if not, good luck.

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

1) How does the oxpecker benefit?
Bezzdna [24]

Explanation:

1)

Oxpeckers are a type of small bird that land on zebras and eat ticks and other parasites that live on the zebra's skin. The oxpeckers get food and the zebras get pest control. ... Tapeworms get food by eating the host's partly digested food, depriving the host of nutrients.

2)i. Fast Speed. Basically, we can process data that is stored in HDFS at lightning-fast speed with traditional SQL knowledge, by using Impala.

ii. No need to Move Data. ...

iii. Easy Access. ...

iv. Short Procedure. ...

v. File Format. ...

vi. Big Data. ...

vii. Relational model. ...

viii. Languages.

3) A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.

In the Internet, a hostname is a domain name assigned to a host computer. ... For example, en.wikipedia.org consists of a local hostname (en) and the domain name wikipedia.org. This kind of hostname is translated into an IP address via the local hosts file, or the Domain Name System (DNS) resolver.

4) Usually, although parasites harm their hosts, it is in the parasite's best interest not to kill the host, because it relies on the host's body and body functions, such as digestion or blood circulation, to live. Some parasitic animals attack plants.

5)The pollen sticks to the hummingbird and as the hummingbird goes to another cardinal flower for food the pollen is spread. This would qualify as a mutual relationship because both of the organisms benefit from the relationship. ... These two organisms have a relationship that is known as mutualism.

6)According to Campbell, moose populations are highest in areas 40 years after a major wildfire. But habitat loss is not the only probable cause of moose decline. Tiny ticks also could be a big problem. ... Without deep snow, then predators like wolves and mountain lions have an advantage over moose.”

Deforestation Led to Decline

The reasons why wolves have seen their population decimated mainly due to the diminishing forests in North America, where many of the wolves are found. Wolves were able to live in and survive in such an environment.

Calculate the standard entropy change for the following reactions at 25°C.
Art [367]

Answer:

(a) ΔSº = 216.10 J/K

(b) ΔSº = - 56.4 J/K

(c) ΔSº = 273.8 J/K

Explanation:

We know the standard entropy change for a given reaction is given by the sum of the entropies of the products minus the entropies of reactants.

First we need to find in an appropiate reference table the standard  molar entropies entropies, and then do the calculations.

(a)        C2H5OH(l)          +        3 O2(g)         ⇒        2 CO2(g)     +    3 H2O(g)

Sº            159.9                          205.2                         213.8                  188.8

(J/Kmol)

ΔSº = [ 2(213.8) + 3(188.8) ]   - [ 159.9  + 3(205.) ]  J/K

ΔSº = 216.10 J/K

(b)         CS2(l)               +         3 O2(g)               ⇒      CO2(g)      +      2 SO2(g)

Sº          151.0                              205.2                         213.8                 248.2

(J/Kmol)

ΔSº  = [ 213.8 + 2(248.2) ] - [ 151.0 + 3(205.2) ] J/K = - 56.4 J/K

(c)        2 C6H6(l)           +        15 O2(g)                     12 CO2(g)     +     6 H2O(g)

Sº           173.3                           205.2                           213.8                    188.8

(J/Kmol)  

ΔSº  = [ 12(213.8) + 6(188.8) ] - [ 2(173.3) + 15( 205.2) ] = 273.8 J/K

Whenever possible we should always verify if our answer makes sense. Note that the signs for the entropy change agree with the change in mol gas. For example in reaction (b) we are going from 4  total mol gas reactants to 3, so the entropy change will be negative.

Note we need to multiply the entropies of each substance by  its coefficient in the balanced chemical equation.
