Answer:

Barium

Explanation:

The specific heat of a material is a property defined as the amount of energy required to increase the temperature of 1g of this material in 1°C = 1K

In this way, the metal that takes the least amount of energy to increase its temperature is the metal that has the lowest specific heat.

In the problem, this metal is Barium (Ba = 0.201J/gK)

A scientist is investigating the structure of aluminum nitrate, which has the chemical formula Al(NO3)3. Based on the chemical f
bekas [8.4K]
The chemical formula of aluminium nitrate is - Al(NO₃)₃
cation is Al³⁺
anion is NO₃⁻
One Al atom binds to three nitrate groups 
the options given are 
2. <span>It has three aluminum (Al) atoms 
this is incorrect as there's only one Al atom 
3. </span><span>It has one NO3 group.
this is incorrect as there are three nitrate groups
4. </span><span>It has nine nitrogen (N) atoms
there are only 3 N atoms therefore this too is incorrect 
</span>therefore the correct answer is - 
It has three NO₃<span> groups

What is the molar mass of H2(SO4)3?​
nalin [4]

Answer:

Explanation:

The molecular mass of C2H6 is approximately 30 or [(2 x 12) + (6 x 1)]. Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14+16).
