im pretty sure, a shade of purple
Did you perhaps mean the phase of matter?
If so, then a solution has only one phase of matter: liquid. It is always almost always liquid because solutions are made up of a solvent and a solute and a solvent is always a liquid. Though, some may come in an emulsion form, but still it can be considered as liquid
Answer:
Characteristics. They are all relatively inert, corrosion-resistant metals. Copper and gold are colored. These elements have low electrical resistivity so they are used for wiring.
Explanation:
Hope this help u

Answer:
Plastic ma be a homogeneous mixture
Explanation:
as the homogeneous mixture are the equal ration blended solution so plastic are also blended in equal proportion with the help of molten state
Niobium-91 will remain 93.75 g
<h3>Further explanation
</h3>
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
The main particles are emitted by radioactive elements so that they generally decay are alpha (α), beta (β) and gamma (γ) particles
General formulas used in decay:
T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Half life -t1/2 of Niobium-91 =680 years
T=duration time=2040 years
No=initial sample=750 g
Niobium-91 will remain :
