Answer:
Coefficient = 3
Subscript for Mg = 1
Subscript for Cl = 2
Explanation:
Coefficient:
A coefficient is number before the chemical formula which tells the number of molecules take part in chemical reaction.
For example:
2H₂ + O₂ → 2H₂O
In this reaction 2 moles of hydrogen react with one mole of oxygen and produce 2 mole of water. The number 2, 1 and 2 are the coefficient.
In given formula 3MgCl₂ the number before the formula which is three is coefficient.
While the number written as subscript tell about the number of atoms of elements. e.g.in MgCl₂ two atoms of chlorine and one atom of magnesium are present in given formula. If only one atom of particular element is present then it is not written as subscript.
The milk has a mass concentration of 17 g/l of fat.
Answer:
Either OB or OC. However, it's asking how to RECORD the notes not measure them so it would be OB. If it's multiple choice choose both.
Explanation:
False, metamorphic rocks are formed under pressure, is crystals are then formed into layers
B. by the water temperature
Explanation:
Morgan should organize her data using given water temperature.
The only variable is the time it takes to dissolve the sugar cubes at different temperatures.
- Data in an experiment should be organized using the variables in the experiment.
- The variables in the experiment are the different water temperature and the time it takes for them to dissolve.
- The size of the glass does not have any effect on the dissolution.
- The amount of sugar is the same.
- There is no amount of sugar left in the glass after the experiment
