Yes, it is possible to combine the same two elements to form two different compounds. An example is carbon dioxide CO2 and carbon monoxide CO. This is because two elements can form different types of bond and end up with different compounds.
There is a limited number of elements but a large number of compounds because of the above reason.
To calculate this, the first step is to determine the number of protons in each atom of the ion. You can use their atomic number to find the number of protons. If the number protons and electrons are equal there is no charge, so the next step is to determine how many electrons to add or remove to the number of protons.
Answer:
i think it is the last option a pure substance that can be separated into different elements by chemical means
Explanation:
O
the amount of heat required to increase the temperature of 1 gram by 1°C
Explanation:
The specific heat of a substance is the amount of heat required to increase the temperature of 1 gram of a substance by 1°C. It is an intensive property that is specific to every substance.
The unit is given as J/g⁻¹°C⁻¹ or J/g⁻¹K⁻¹
This related to the quantity of heat using the expression below:
Q = mC∅
Q is the quantity of heat added
m is the mass
C is the specific heat
∅ is the temperature change.
