"I" symbol means the current goes through the system (imagine the 'I' being a line, like a circuit connecting [power to the device]) "O" symbol means the current does not go through the system. ( the circle is an open circuit, having no power flowing through it
We know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume.
Given two of the variables, we can then solve for density:
So therefore, we now know that the density of carbon dioxide gas is 0.00196g/mL.
Answer: A) Sodium Na and Magnesium Mg
Explanation:
In the period table, you can see that Sodium (group 1) has 11 protons, and Magnesium (group 2) has 12 protons. 11+12=23 protons
A way of building knowledge about the world around us through observation and experimentation.
Glucose is carbohydrate and a simple sugar that is very important to the human body.
Energy is produced for the cells in the body through the process of metabolism which oxidizes glucose to water, carbon dioxide, and some nitrogen compounds.
The general chemical reaction equation for metabolism is:
C6H12O6 + 6O2 ---> 6CO2 + 6H2O
