Answer:

1.5 × 10² mL

Explanation:

Step 1: Given data

Initial pressure of the gas (P₁): 1.9 atm

Initial volume of the gas (V₁): 80 mL

Final pressure of the gas (P₂): 1.0 atm (standard pressure)

Final volume of the gas (V₂): ?

Step 2: Calculate the final volume of the gas

For an ideal gas, we can calculate the final volume of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 1.9 atm × 80 mL/1.0 atm

V₂ = 1.5 × 10² mL

Since the pressure decreased, the volume of the gas increased.

Which of these describes an exothermic reaction?

Paul [167]

A nswer: -

C. Energy is released by the reaction

Explanation:-

An exothermic reaction is one in which during the progress of the reaction heat is evolved.

So energy is released by the reaction.

It cannot be created as energy is neither created nor destroyed as per the Law of conservation of energy. Energy is not transferred either.

The energy released during the progress of the reaction originates from the chemical bonds of the reactants as they break during their conversion into products.

The heat capacity of water is 1cal degree'g1 (1 calorie per degree centigrade, per gram). You are given 1 gallon of water at 25

sdas [7]

Answer:

The heat needed to boil 1 gallon of water is 81,490.62 Joules.

Explanation:

$Q=mc\Delta T$

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance

ΔT = change in temperature of the substance

We have :

Volume of water = V = 1 gal = 4546.09 mL

Density of water , d= 1 g/mL

mass of water = m = d × V = 1g/mL × 4546.09 mL = 4546.09 g

Specific heat of water = c = 1 Cal/g°C

ΔT = 100°C - 25°C = 75 °C

9 (boiling pint of water is 100°C)

Heat absorbed by the water to make it boil:

$Q= 4546.09 g\times 1 Cal/g^oC\times 75^oC=340,956.75 Cal$

1 calorie = 4.184 J

$Q=\frac{340,956.75}{4.184} J = 81,490.62 J$

The heat needed to boil 1 gallon of water is 81,490.62 Joules.

When this element was discovered, it exhibited luster and malleability, and it reacted very vigorously with water. This element

TEA [102]

Answer:

a) alkali metals

Explanation:

The element described above definitely belonged to the alkali metals, the first group on the periodic table. They show the properties indicated in the text.

They are metals because only metals are lustrous and malleable. This eliminates the possibility of them being halogens and noble gases.
Only group 1 metals reacts vigorously with water to form alkali.
Alkali are aqueous solutions that are basic in nature.
The reactivity of group 1 metals is due to their one extra electrons in the outer most shell.
These electrons are easily and readily lost in order for such atoms to gain stability and replicate the nearest noble gases.
The most reactive metal belongs to this group elements.
This is why it is nearly impossible to find them occurring alone in free state.
Some of the elements in this group are Li, Na, K, Rb, Cs and Fr.
Transition metals have variable oxidation states and some can be found alone in nature.
