It is a single replacement reaction. Li and Mg switch places.
Answer:
The new temperature is 1596 C.
Explanation:
Charles's Law indicates that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases.
Statistically, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio that exists between the volume and the temperature will always have the same value:
Being an initial state 1 and a final state 2, it is fulfilled:
In this case:
- V1= 25 L
- T1= 350 C= 623 K (being 0 C= 273 K)
- V2= 75 L
- T2= ?
Replacing:
Solving:
T2= 1869 K= 1596 C
<u><em>The new temperature is 1596 C.</em></u>
Answer:
B.) 6
Explanation:
Attached below is the Lewis structure of PCl₃ . Since phosphorus (P) has 5 valence electrons and chlorine (Cl) has 7 valence electrons, there should be 26 valence electrons (5 + 7(3) = 26) in the Lewis structure.
Bonding electrons are the electrons present in the chemical bonds between two atoms.
There are 2 electrons shared in every single bond. Within PCl₃, there are 3 single bonds. As such, there are 6 bonding electrons in the Lewis structure of PCl₃.
Step one of the Hydrogen fusion process helium a nucleus of Deuterium is formed from two protons with the emission of an antielectron and a neutrino.
The fundamental Hydrogen fusion cycle includes 4 Hydrogen nuclei and two electrons and yields a Helium nucleus, two neutrinos and six photons. The principle series phase is the stage in development where the center temperature reaches the point for the fusion to begin. in this manner, the protons of hydrogen are converted into atoms of helium.
If the star is big sufficient to fuse hydrogen atoms into helium, it's going to enter the phase that our solar is in, referred to as the primary sequence section. a celebrity will enjoy most of its existence in the major series section. At this point nuclear fusion is turning hydrogen into helium.
A star isn't always absolutely a star until it is able to fuse hydrogen into helium. before that, they are called Protostars. A protostar is fashioned as gravity begins to tug the gases together right into a ball. This process is referred to as accretion.

First, if you want to get the amount of production from the equation, you need to use the units of mol. So, we need to know the molar mass of C which is 15.75/12=1.31 mol. Then we need to use the less part(O2) to get the production amount which is 0.116 mol. Then we can get the answer in units of g: 0.116*(12+16*2)=5.104 g.
