An aluminum block has a density of 2.70 g/mL. If the mass of the block is 24.60 g, find the volume of the substance.
harina [27]

Volume of a substance can be determined by dividing mass of the substance by its density.

That can be mathematical shown as:

Density=Mass/Volume

So, Volume=Mass/Density

Here mass of the substance given as 24.60 g

Whereas density of the substance is 2.70 g/mL

So,

Volume=Mass/Density

=24.6/2.7

=9.1 mL

So volume of the substance is 9.1 mL.

The ion n3− has _____ protons and _____ electrons.enter your answers as integers separated by a comma.
bearhunter [10]
The ion N³⁻ is called the azide ion. In its neutral state, it occurs as the element Nitrogen. The atomic number of Nitrogen is 7. When it turns into an anion (negatively charged ion), it gains 3 more electrons. That's why its net charge becomes -3. It means that the protons is still 7, but the electrons are now 10. 

Overall charge = +7 + -10 = -3

Select the correct answer. Based on the reactivities of the elements involved, which reaction will form products that are more s
FinnZ [79.3K]

Answer: The correct answer is option B.

Explanation: Reactivity of elements is defined as the tendency to loose or gain electrons.

These reactions are a type of single displacement reactions. A single displacement reaction is a type of reaction in which an element displaces another element in a chemical reaction. These are studied with the help of reactivity series.

The element which lies above in the reactivity series can easily displace the element which lies below in the reactivity series.

Option A: This reaction will not yield a stable product because Zinc lies below Aluminium in the reactivity series.

AlBr_3+Zn\rightarrow \text{No reaction}

Option B: This reaction will yield a stable product because Sodium lies above Calcium in the reactivity series.

CaBr_2+2Na\rightarrow 2NaBr+Ca

Option C: This reaction will not yield a stable product because Hydrogen lies below Magnesium in the reactivity series.

MgBr_2+H_2\rightarrow \text{No reaction}

Option D: This reaction will not yield a stable product because Calcium lies below Barium in the reactivity series.

BaBr_2+Ca\rightarrow \text{No reaction}

Option E: This reaction will not yield a stable product because barium lies below Lithium in the reactivity series.

2LiBr+Ba\rightarrow \text{No reaction}
