17. Which solution is more concentrated?

Chemistry
1 answer:
Stella [2.4K]3 years ago
6 0

Answer:

Solution 1.

Explanation:

We can find the concentration of a solution by looking at the ratio of the components.

In the first solution, there is a 500 mL:100g ratio. In the second, there is a 500mL:90g ratio. The greater ratio, or the ratio with a greater amount of solute in proportion to the water, is the first.

How does induced transmutation produce trans uranium elements ?
kifflom [539]
Answer: Artificial transmutation may occur in machinery that has enough energy to cause changes in the nuclear structure of the elements. This releases, on average, 3 neutrons and a large amount of energy. The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted.

Calcium oxide (cao) can react with carbon dioxide (co2) in a synthesis reaction. Select the most likely products of this reactio
Triss [41]

Answer: Option (b) is the correct answer.

Explanation:

A synthesis reaction is the reaction in which two compounds or atoms combine together to result in the formation of a single compound.

For example, CaO + CO_{2} \rightarrow CaCO_{3}

Thus, here CaO and CO_{2} combine together to result in the formation of calcium carbonate compound. Therefore, it is a synthesis reaction.

Therefore, we can conclude that the most likely products of Cao + co2 → CaCO3 reaction.

The main acid in the stomach is hydrochloric acid (HCl). Which chemical equations show a reaction that occurs when someone takes
777dan777 [17]
I think the correct answer would be HCl + NaHCO3 -> NaCl + H2O + CO2, 2HCl + CaCO3 -> CaCl2 + CO2 + H2O, 2HCl + Mg(OH)2 -> MgCl2 + 2H2O. Hydrochloic acid would react with the basic substances in the stomach which are magnesium hydroxide, sodium bicarbonate and <span>calcium carbonate.</span>

A gas at STP has a volume of 1.5 L. What will the pressure be if it is at 26° C occupying .75 L​
andrey2020 [161]

Answer:

P₂ =  2.19 atm

Explanation:

Given data:

Initial volume = 1.5 L

Initial pressure =1 atm

Initial temperature = 273K

Final temperature = 26°C (26+273 = 299 K)

Final volume = 0.75 L

Final pressure = ?

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₂ = P₁V₁ T₂/ T₁ V₂  

P₂ = 1 atm × 1.5 L × 299 K / 273 K × 0.75 L  

P₂ = 448.5 atm .L. K / 204.75 K.L

P₂ =  2.19 atm
