Answer:
see below
Explanation:
1) Since PST is 3 hours behind EST it will be 3:30 - 3 = 12:30 pm PST.
2) Oregon is in PST and NY is in EST so it'll be 10 - 3 = 7 pm in Oregon.
3) Ohio is in EST and Chance is in CST so it'll be 9 + 1 = 10 am in Ohio.
<span>Unless otherwise stated, the common room
temperature and pressure is at 25°C and 1 atmosphere, respectively. At this
temperature and pressure hydrogen chloride is expected to be in a gaseous state.
Since it is a diatomic molecule consisting of hydrogen and chlorine atoms, they
have weak forces of interaction between molecules resulting to an uncondensed
state at room temperature. If the atmosphere where is it suspended has
moisture, hydrogen chloride gas is expected to react with the moisture to form
fumes of hydrochloric acid.</span>
Explanation:
Thomson model compared the structure of the atom with a watermelon in which the red portion signifies the positive charge and the electrons which are negatively charged are embedded in this portion as seeds are embedded in the watermelon.
<u>The structure was not able to explain the stability of the atom and also the Rutherford experiment which is:</u>
Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:
- Most of the alpha particles get through the film and can be detected by the detector.
- Around small portion of the alpha particle deflected at small angles.
- A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.
He concluded that:
Most of space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave term nucleus to this solid mass.
A dentist uses thermal expansion in the filling of a material to a tooth since any material when exposed to heat expands in a certain degree depeding on the material. in this case, it is best that the material used for filling is more or less a ceramic one in which heat expansion is not that great to disturb the configuration of the teeth
Hello.
The answer is 1417.7
Its 1417.7 grams becasue you have to convert the moles to grams.
<span /><span><span>A mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.023 X 1023).
</span><span>a coherent, typically large body of matter with no definite shape.
Have a nice day</span></span>
