The error that would make the calculated density of the solid have if the material had a hollow center is that the calculated density would be low, because the volume would be incorrectly measured high.
<h3>What is density?</h3>
The measure of how densely a material is packed together is called density. As the mass per unit volume, it has that definition. Density Formula: = m/V, where is the density, m is the object's mass, and V is its volume. Density Symbol: D.
If a substance had a hollow center, its volume would be high and its density would be low.
Therefore, the error that would make the calculated density of the solid have if the material had a hollow center is that the calculated density would be low, because the volume would be incorrectly measured high.

Answer:
Explanation:
Lithium, Potassium and Sodium follow each other in that order when it comes to reactivity.
Succinctly put, Lithium is the most reactive. Potassium is more reactive and Sodium is the least reactive.
Also, for Calcium, Strontium and Barium. It is the least reactive in this order.
Strontium, Barium, Calcium
That is, Strontium is more reactive than Barium, which is more reactive than Calcium. Calcium is the least reactive of the 3
Answer: 0.771 g of 
will be produced
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of 
produce = 3 moles of
Thus 0.257 moles of will produce=
of
Mass of 
Thus 0.771 g of will be produced
Answer:
Should be 0.6106 though i could be wrong
Explanation:
Answer:
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
