1) Reaction:
Mg(s) + 2HCl (aq) ----> H2(g) + MgCl2(aq)
2) Analysis
An increase in pressure affects directly the rate of reaction involving reactiong gases. Changing the pressure where there are only solids or liquids does not affect the rate of reaction.
This reaction is not an equilibrium, the reaction is only forward. So, the reacting components, Mg(s) and HCl(aq) are a solid and a liquid.
Therefore, the reaction is not affected by the change in pressure.
Answer: the reaction is not affected at all.
Answer: about 5 Mg
Explanation:
Because that sounds right
Its a 3.0m solution so 1 litre of solution contains 3 moles of NaOH, 250ml of solution contains 0.25x39.9971 g/mol, so 250ml of this solution contains 0.75x39.9971=29.99g, or if you round it up 30.0g
Answer:
See attached image.
Explanation:
Hello there!
In this case, according to the isomeric structure of hydrocarbons, it is possible to draw a five-carbon hydrocarbon with a tertiary carbon by keeping in mind these tertiary carbons are characterized by the presence of three bonds with carbon atoms.
In such a way, as shown on the attached image, the second carbon from left to right is tertiary because of the aforementioned, and also, the compound has five carbon atoms and twelve hydrogen atoms.
Best regards!
In balancing chemical equations, all you need to do is make it so that you have the same number of each element on both sides of the eqtn (if I have 5C on the left, I have to have 5C on the right — an element can’t magically appear or disappear); that being said:
(2)C2H6 + 7O2 ➡️ 6H2O + 4CO2
(12)HClO4 + P4O10 ➡️ 4H3PO4 + (6)Cl2O7
2N2 + (5)O2 + 2H2O ➡️ 4HNO3
(3)CaCl2 + 2Na3PO4 ➡️ (1)Ca3(PO4)2 + 6NaCl
4FeS + 7O2 ➡️ 2Fe2O3 + 4SO2
