Out of
the following given choices;
A. increasing
the pH of the salt.
B. increasing
the surface area of the salt.
C. increasing
the pressure of the salt.
<span>D. increasing
the temperature of the salt.</span>
The answer is B. When a substance is reduced to smaller
sizes, its surface area to volume ratio increases. Therefore crushing barium
salts to smaller particles increase the surface area on which it reacts with
the acid. This consequently increases the rate of speed of the reaction.
Sodium, Carbon, Oxygen, Hydrogen, Nitrogen, Phosphorous, and Sulfur.
The names of the compounds differ by the type of metal present in them, which are Calcium (Ca) and Cadmium (Cd)
From the question,
We are to determine the how the name of CaS differ from the name of CdS
First, we will determine the identities of the elements in the given compounds
Ca represents calcium
and
S represents sulfur
∴ The compound is named Calcium sulfide
Cd represents the element Cadmium
and
S represent the element Sulfur
∴ The compound is named Cadmium sulfide
Hence, the names of the compounds differ by the type of metal present in them, which are Calcium (Ca) and Cadmium (Cd)

Answer:
stratosphere - The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward.
mesosphere - The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere
thermosphere - The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere.
Mass of NO₂= 203.32 g
<h3>Further explanation</h3>
Given
99.0 L of NO₂
Required
Mass of NO₂
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
So mol NO₂ :
= 99 : 22.4
= 4.42
Mass :
= mol x MW
= 4.42 x 46 g/mol
= 203.32 g
