bonufazy [111]
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.

Calculate the molar mass of naoh and the mass of solid naoh needed to prepare 250 ml of 0.1 m naoh solution
ella [17]
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

C5h12 with one tertiary carbon
AfilCa [17]

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!

Can you please help me with this??
tensa zangetsu [6.8K]
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
