Answer:
The boiling point is the temperature at which the vapor pressure equals the pressure of gas.
The normal boiling point is the temperature at which the vapor pressure equals one atmosphere
Explanation:
Answer:
synthesis
Explanation:
The reaction given is a synthesis reaction or combination reaction.
Given equation:
NH₃ + HCl → NH₄Cl
In a synthesis reaction, a single product is formed from two or more reactants
A + B → C
The formation of compounds from the union of constituent elements also falls into this category.
So the given reaction is a synthesis reaction.
In a decomposition reaction two or more products are formed from a single reactant
In a single replacement reaction, one substance replaces another.
In double replacement reactions partners in a chemical specie are exchanged.
Therefore the given reaction is a synthesis reaction
Rate = k[A] = first order reaction
<h3>Further explanation</h3>
Given
Rate law
Required
A first-order reaction
Solution
The rate law : equation for the rate of chemical reaction
For reaction
aA + bB ⇒ C
The rate : r = k[A]ᵃ[B]ᵇ
The sum of exponents(a+b) is the reaction order
From the choice :
a. a+b = 2, second order reaction
b. a+b = 3, third order reaction
c. a+b = 4, fourth order reaction
d a+0 = 1, first order reaction
A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies. A probe may operate far out in space, or it may orbit or land on a planet or a moon. It may make a one-way journey, or it may bring samples and data back to Earth. Most probes transmit data from space by radio. There are different types of space probes because they collect different science information about very different environments. The probes must be able to withstand the various extreme environments to collect data. Humans have been sending space probes into space since the 1950s. The next generation of probes will study samples taken from comets, asteroids, and eventually Mars.
No it does not ALWAYS go through all the stages because each rock forms differently at different rates. Igneous rock can weather to sediement rock, or melt to magma, however this does not necessarily mean it does this every time. It all depends on the temperature, wind, and pressure/heat.
