Answer: 2.17 g of bromide product would be formed
Explanation:
The reaction of calcium bromide with lithium oxide will be:
To calculate the moles :
As lithium oxide is in excess, calcium bromide is the limiting reagent.
According to stoichiometry :
1 mole of produce = 2 moles of
Thus 0.0125 moles of will require= of
Mass of
Thus 2.17 g of bromide product would be formed
Answer:
You'll have to record the observations in appropriate ways and organize them The way you collect your data should relate to how you're planning to analyze and use it These might for instance include entering numerical observations into a Qualitative data are collected as descriptions anecdotes opinions quote
Explanation:
True, because his model has the electrons in the sphere of the atom, Thomson’s model was called the “Plum Pudding” model because it was popular and relatable at his time.
Hope this helps!! ^v^
Answer:
Explanation:
18.01528 g/mol. I googled this, but it would be 16 for O plus 2 for the 2 H's. 18 g/mol divided by 12.5g=1.44 mol of H20.
1.44mol* molecules/mol= 8.6688*10^23.
Answer:
75 inches
Explanation:
A student builds a model of her own bedroom
The scale of the model is 1:25
In the scale model the bed of the student is 3 inches long
Therefore the length of the student's actual bed can be calculated as follows
= 3 × 25
= 75 inches
Hence, the student's actual bed is 75 inches long
