The gas with a higher pressure is  <u>Helium </u>

<h3 /><h3>Calculating the pressure exerted by the gases</h3>

Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.

<u>Pressure of </u><u>Helium </u>

P = n

where n ( number of moles ) = mass of helium / molar mass

                                               = 52 / 4 = 13 moles

<u>Pressure of</u><u> Ammonia </u>

P = n

where n ( number of moles ) = mass  / molar mass of ammonia

                                                = 73 / 17.03

                                                = 4.29 moles

From the calculations above the gas with a higher pressure is Helium.

What’s (2a) with an exponent of 6/5 in radical form?
VashaNatasha [74]
<h3>Answer: Choice A</h3>

Reason:

Use the rule that a^{b/c} = \sqrt[c]{a^b} = \left(\sqrt[c]{a}\right)^b

This means, (2a)^{6/5} = \sqrt[5]{(2a)^6} = \boldsymbol{\left(\sqrt[5]{2a} \ \right)^6}

As another example, m^{2/3} = \sqrt[3]{m^2} = \left(\sqrt[3]{m} \ \right)^2

A typical neutron star has a mass of about 1. 5msun and a radius of 10 kilometers
Triss [41]

How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

<h3>Density of the Neutron star</h3>

Density

ρ = m / V

Where:

ρ= density

m = mass of the planet 5.98 10²⁴ km

V =volume of the spherical layer

Volume of a sphere

Volume = 4/3 π r³

Mass = 1.5 = 1.5 1,991 10³⁰

Mass= 2.99 10³⁰ kg

Density:

ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]

ρ is = 7.13 10 17 kg / m³

V = 5.98 10²⁴ / 7.13 10¹⁷

V = 8,387 10⁶ m³

Thickness of the layer

V = 4π r² e

e = V / 4π r

e = 8,387 10⁶ / [4π (10 10³)²]

e = 6.67 10⁻³ m

Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

I need the full thing solved
Nesterboy [21]

Answer:

x-axis: Amount of candy sold

y- axis: Amount of money made

Billy is making $0.20 per candy bar.

Linear function: y=3/5x-6

Billy sold 50 candy bars if he made $24.

The x-intercept represents the point when he will earn a profit because at point (5,-3) he sold 5 candy bars but he still made a loss of $3.
