True.

Explanation:

Moles =mass/molarmass

Moles Ne =mass/molarmass

$=\frac {10.3g}{(20.18g per mole)}=0.510mol$

Moles N_2 =mass/molarmass

$=\frac {10.3g}{(28g per mole)}=0.368mol$

Let Temperature be 273K (assumed)

PV=nRT

$P=\frac {nRT}{V}$

$P_{Ne}=\frac {0.510mol \times 0.08206L atm K^{-1} mol^{-1} \times 273K}{7.0L}$

$P_{Ne}=1.63atm$

$P_{N_2}=\frac {0.368mol \times 0.08206L atm K^{-1} mol^{-1} \times 273K}{7.0L}$

$P_{N_2}=1.17atm$

We see here partial pressure of N_2 (1.17atm) is less than that of partial pressure of Ne (1.63 atm).

this is the answer

Explanation:

Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses”. Impulses rush along tiny fibres, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.
