Answer:
89.6L
Explanation:
1mole of any gas occupies 22.4L. This simply means that,
1mole of CO2 occupies 22.4L at stp.
Therefore, 4moles of CO2 will occupy = 4 x 22.4 = 89.6L
The units used to measure specific heat capacity is Joules per kilogram per Kelvin.
<h3>
What is specific heat capacity?</h3>
It is the amount of heat absorbed per kilogram of material when the temperature rises by 1 Kelvin.
Specific heat capacity C is the Joules of energy in form of heat per kilogram per Kelvin temperature. The units represented by
C = ___ J/kg.K
Thus, the units used to measure specific heat capacity is Joules per kilogram per Kelvin.

Answer:
Copper
Explanation:
copper is used in the wiring of the phone
When a monovalent cation X binds to a divalent anion Y, a compound with the formula 
would be formed.
A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be 
A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be 
Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of would be required to successfully bind

Answer:
Fe₂O₃
Explanation:
To solve this question we must find the moles of Iron in 1.68g. With the difference of the masses we can find the moles of oxygen. The formula will be obtained with the ratio of both amount of moles:
<em>Moles Fe:</em>
1.68g * (1mol / 56g) =0.03moles
<em>Moles O:</em>
2.40g-1.68g = 0.72g * (1mol/16g) = 0.045moles
The ratio O/Fe is:
0.045moles / 0.03moles = 1.5 moles. this ratio is obtained if the formula is:
<h3>Fe₂O₃</h3>
