Explanation:
We can tell if a chemical reaction has taken place when one or more of the following things happen:
1.There has been a colour change inside the reaction flask.
2. A gas has formed. Usually we know a gas has formed when we can see bubbles.
3.A solid has formed.
hope this answer helps!!!
Answer:
A: Volume and Amount of Gas
B: 3
C: 4
D: 4
E: 3
F: Gay-Lussac's Law
G: Directly Proportional Relationship
Explanation:
A: When looking at the information given, each container contains the same amount of particles and the size of the container is stated to be the same. Therefore, these two variables remain constant.
B: KE is determined by the temperature, which means the container with particles at the highest temperature has the highest amount of KE. This would be container 3.
C: The container with the lowest temperature is 4.
D: The container with the lowest pressure is 4 because a lower temperature means lower pressure.
E: The container with the highest temperature has the highest pressure because the particles are moving faster, meaning more pressure exerted against the container.
F: Gay Lussac's Law because this law shows the relationship between pressure and temperature.
G: This is a directly proportional relationship because as temperature increases, pressure increases. As temperature decreases, pressure decreases.
I’m so sorry if it’s wrong but I think it’s this.....
Answer:
2NaHCO3(s) = Na2CO3(s) + CO2(g) + H2O(g).
And I found it on Quora.com
By the way NaHCO3 is Sodium bicarbonate but a.k.a Baking soda
Hoped this helped :)
Answer:
A
Explanation:
A common example of heterogeneous catalysis is the hydrogenation reaction of simple alkenes. The conversion of ethene (C2H4) to ethane (C2H6) can be performed with hydrogen gas in the presence of a metal catalyst such as palladium (“Conversion of Ethene to Ethane with Hydrogen and a Metal Catalyst”).
The question is all about which among the given choices is true or properly describes the valence electron of the metallic bonds. These valence electrons of the metallic bond is shared amongst many atoms so that the metals can be bounded together. Hope this answers your qn. :)
