Predict the empirical formula of the ionic compound that forms from magnesium and oxygen?
The empirical formula of the ionic compound formed from magnesium and oxygen is MgO. Magnesium (Mg) has a +2 charge, and oxygen (O) has a -2 charge. The charges balance out in a 1:1 ratio, resulting in MgO.
What are characteristics of empirical evidence?
Empirical evidence is based on direct observation or experience rather than theory or logic. It is verifiable through experimentation or observation and can be used to support or refute hypotheses. Empirical evidence is often used in scientific research to make conclusions based on real-world data.
What is the name of the compound with the formula Ba(NO3)2?
The compound with the formula Ba(NO3)2 is called barium nitrate. It is a white crystalline solid often used in fireworks to produce a green flame.
What is the formula for ethanol?
Ethanol: CH3CH2OH, often abbreviated as C2H5OH or C2H6O
What is the chemical formula for antimony V?
The chemical formula for antimony V is Sb2O5. It is often referred to as antimony pentoxide.
The empirical formula is CH2O. What is the molecular formula of this compound?
The molecular formula of a compound is a multiple of its empirical formula, so the molecular formula is a multiple (in this case, 6 times) of CH2O, giving C6H12O6. This molecular formula corresponds to glucose, a common sugar.
What are Chemical formulas for ethanol?
The molecular formula of ethanol is written as either CH3CH2OH or C2H5OH, and its empirical formula is C2H6O. It is often written as EtOH.
Why do you use both empirical and molecular formula?
Empirical formula shows the simplest whole-number ratio of different atoms in a compound, while molecular formula shows the actual number of each type of atom in a molecule. Using both formulas provides more information about the composition and structure of a compound.
What are observed results?
These are results which you look at or observe with your eyes. This can often be called empirical results.
What is called an equation that relates two or more quantities?
It is often called a formula.
Predict the empirical formula of the ionic compound that forms from magnesium and oxygen?
The empirical formula of the ionic compound formed from magnesium and oxygen is MgO. Magnesium (Mg) has a +2 charge, and oxygen (O) has a -2 charge. The charges balance out in a 1:1 ratio, resulting in MgO.
How do you find the molecular and empirical formulas?
To find the empirical formula, determine the simplest whole-number ratio of atoms in the compound. To find the molecular formula, compare the compound's molar mass to the empirical formula's molar mass to calculate the multiplier. Multiply the subscripts in the empirical formula by this multiplier to get the molecular formula.
In the scientific world cold hard facts are often termed?
empirical evidence or data.
What is a tribal leader?
A tribal leader is called a chief. Some tribes choose to have multiple male leaders, in this case the leaders are often called kings.
What are characteristics of empirical evidence?
Empirical evidence is based on direct observation or experience rather than theory or logic. It is verifiable through experimentation or observation and can be used to support or refute hypotheses. Empirical evidence is often used in scientific research to make conclusions based on real-world data.
What are questions about observations in the physical world called?
Questions about observations in the physical world are called empirical questions. These questions seek to understand and explain phenomena through direct observation or experience. They are often answered using scientific methods and evidence.
Waves often appear as a series of crests called?
Waves often appear as a series of crests called wave trains. These wave trains consist of multiple individual waves following one another in succession.
