Answer:
B
Explanation:
Presumably the system is closed (nothing can escape or enter).
A: You're cooling the container so it shouldn't explode.
C: If the container is Closed, the volume cannot increase or decrease.
D: is also impossible for the closed container reason.
B: The pressure has to decrease because the molecules are moving slower which decreases their velocity. If that happens the Force goes down.
B: Answer
Answer:
Molecular compounds consist of two or more nonmetals. The nonmetals that make up a molecular compound are held together by covalent/molecular bonds. Covalent bonds is known as the "sharing" of valence electrons between two or more chemical species. Valence electrons are shared so that the atoms of the compound can become stable, much like how ionic bonds transfer valence electrons between atoms to achieve stability.
The reaction rate is the speed at which products form, based on the rate of the slowest step in the mechanism.
Dull (not shiny)
poor conductors of heat and electricity (they are insulators)
weak and brittle (they easily break or shatter when solid)
Answer:
Mass, m = 7.97 grams
Explanation:
We have,
Initial temperature was 34 degrees Celsius
Heat produced in it is 100 calories of heat
The specific heat capacity of water is 4.18 J/g °C
The heat produced due to change in temperature is given by :
m is mass of water in grams
So, 7.97 grams of water is required to produce heat of 2200 joules.
