I think you're talking about protons, neutrons, and electrons, but I'm not sure.

What is the molar mass of an ideal gas if a 0.800 g sample of this gas occupies a volume of 200. mL at 50.0 oC and 720. mm Hg?

Paladinen [302]

PV=nRT
(720/760)(0.200)=(0.800/x)(0.08206)(323.15)
(0.1894736842)=(0.800/x)(0.08206)(323.15)
.0071451809=(0.800/x)
x=MM=111.9635758 g/mol

A girl of weight 500 N climbs on top of a 2.0 m high wall. By how much does her g.p.a increase?

Anna007 [38]

Answer:

By 1000 joules

Explanation:

Given

$Weight = 500N$

$Height = 2.0m$

Required

By how much does her GPA increases

To do this, we simply calculate the potential energy.

$GPE = mgh$

Where

$mg = Weight = 500N$

At the ground level, the height is 0

i.e. $h = 0$

So:

$GPE = 500N * 0 = 0$

At:

$h = Height = 2.0m$

So, we have:

$GPE = mgh$

$GPE = 500N * 2.0m$

$GPE = 1000J$

Calculate the difference

$\triangle GPE = 1000J - 0J$

$\triangle GPE = 1000J$

<em>Hence, it increases by 1000 joules</em>

What is the charge of an object that has more electrons than protons? More protons than electrons? The same number of protons an

aliya0001 [1]

Answer:

If an object has more electrons than protons it is NEGATIVELY charged. If there are more protons than electrons it is POSITIVELY charged. If the number of protons and electrons are the same it is NEUTRAL.
