Use your understanding of the ideal gas law to

PolarNik [594]

Answer:The ideal gas law is represented mathematically as: PV=nRT. P- pressure, V- volume, n-number of moles of gas, R- ideal gas constant, T- temperature.

Explanation:The ideal gas law is used as a prediction of the behavior of many gases, when subjected to different conditions.

he ideal gas law has so many limitations.

An increase in the pressure or volume, decreases the number of moles and temperature of the gas.

Empirical laws that led to generation of the ideal gas laws, considered two variables and keeping the others constant. This empirical laws include, Boyle's law, Charles's law, Gay Lusaac's law and Avogadro's law.

Calculate the mass (in g) of 2.1 x 1024 atoms of W.

Monica [59]

Atomic mass W = 183.84 u.m.a

183.84 g ----------- 6.02x10²⁴ atoms
?? g ---------------- 2.1x10²⁴ atoms

2.1x10²⁴ x 183.84 / 6.02x10²⁴ =

3.860x10²⁶ / 6.02x10²⁴ = 641.30 g

Chem<br> Equations<br> Balance and Classify each of the following equations into:<br> Combination reaction, Decomposition Reacti

Arlecino [84]

Answer :

(A) The balanced chemical reaction will be:

$2KBr(aq)+Cl_2(g)\rightarrow 2KCl(aq)+Br_2(l)$

This reaction is a single replacement reaction.

(B) The balanced chemical reaction will be:

This reaction is a double displacement reaction.

(C) The balanced chemical reaction will be:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

This reaction is a combination reaction.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of an element present on reactant side must be equal to the product side.

Part (A):

The balanced chemical reaction will be:

$2KBr(aq)+Cl_2(g)\rightarrow 2KCl(aq)+Br_2(l)$

This reaction is a single replacement reaction in which the most reactive element displaces the least reactive element from its solution.

Part (B):

The balanced chemical reaction will be:

$CaBr_2(aq)
+H_2SO_4(aq)\rightarrow CaSO_4(s)+2HBr(g)$

This reaction is a double displacement reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

Part (C):

The balanced chemical reaction will be:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

This reaction is a combination reaction in which the two atoms combine to form a larger molecule.
