Answer:
First, let's express pressure P in Pa and volume V in m3:
⇒P=175 kPa
⇒P=1.75×105 Pa
and
⇒V=275 ml
⇒V=2.75×10−4 m3
Then, let's solve the ideal gas law PV=nRT for temperature T:
⇒PV=nRT
⇒T=PVnR
Substituting the appropriate values into the equation:
⇒T=1.75×105×2.75×10−40.80×8.314 K
⇒T=48.1256.6512 K
∴T≈7.24 K
Therefore, the temperature is around 7.24 K.
Answer:
6 atoms
Explanation:
In 6 moles of HCL (hydrochloric acid), there are 6 hydrogen atoms. Think about it this way: there is one hydrogen atom in HCL, or one hydrogen atom in one mole of HCL. Since there are 6 moles of HCL instead of one, this means there are six times as many hydrogen atoms. 6 times 1 is 6.
Answer:
Types of bonding in chemistry
There are three primary types of bonding: ionic, covalent, and metallic. Definition: An ionic bond is formed when valence electrons are transferred from one atom to the other to complete the outer electron shell.

<u>Answer:</u>
<em>B Mass </em>
<em>D Force </em>
<em>E Acceleration</em>
<u>Explanation:</u>
We know that
Force = mass × acceleration
F = m × a
The unit of force is newtons
The unit of mass is kg and
the unit of acceleration is
Force and acceleration are vector quantities and mass is a scalar quantity.
Newton's 2nd law of motion states that acceleration is directly proportional to net force and inversely proportional to mass.
he result is the equation
