2) Cold War tensions increased.

The Bay of Pigs invasion was carried out by Cuban exiles that had been trained by the United States' Central Intelligence Agency (CIA). The Cuban counter revolutionaries failed and Kennedy was embarrassed. Within just days, the force of exiles was soundly defeated by the Cuban Revolutionary Armed Forces, commanded by Fidel Castro. In the aftermath of the Bay of Pigs affair, Cuba requested that the USSR, as its communist sponsor, place missiles in Cuba to deter further US-sponsored action against the Castro regime.

A gaseous compound has a mass of 8.00 g at 2.81 atm and 300. K in a 1.00 L container.

Maurinko [17]

Answer:

The question asks for moles, which can be obtained from P-V-T data using the ideal gas

equation: n =

PV .

Now use the rearranged gas law to determine the number of moles in the sample:

n = PV

RT = (6.47 x 105 Pa)(5.65 x 10-4m3

)

(8.314 J

mol K )(21.7 + 273.15 K) = 0.149 mol.

All conditions except the pressure and volume are fixed, so P1V1 = P2V2 can be used: 3.62 L

101kPa

(647 kPa)(0.565 L)

Chloroform has a density of 1.483g/ml. A sample of chloroform has a volume of 1.93 liters. How many kilograms does it weight?

ollegr [7]

Weight of Chloroform : = 2.862 kg

<h3>Further explanation</h3>

Given

Density 1.483 g/ml

Volume = 1.93 L

Required

Weight of Chloroform

Solution

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density

m = mass

v = volume

Convert density to kg/L :

=1.483g/ml = 1.483 kg/L

So the weight(mass) :

= ρ x V

= 1.483 kg/L x 1.93 L

= 2.862 kg

A chemical reaction in which one element replaces another element in a compound can be catergorized as a

Gwar [14]

Answer:

$\huge\boxed{\sf Single \ displacement \ reaction}$

Explanation:

<h2><u>Displacement reaction:</u></h2>

A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.

<h3><u>Types:</u></h3>

There are 2 types:

<h3><u>1. Single displacement reaction:</u></h3>

If one element displaces 1 other element of a compound, it is called single displacement reaction.
<u>Example</u>: $CuSO_4 +Fe \longrightarrow \ FeSO_4 + Cu$
Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.

<h3><u>2. Double displacement reaction:</u></h3>

If two elements in two compounds displace one another, it is called double displacement reaction.
<u>Example:</u> $CuSO_4+NaOH \longrightarrow Cu(OH)_2 + Na_2SO_4$
Here, Copper and sodium both displace each other.
