Yes I think & I Belive it moves across the surface
<span> The nuclear reactor powers plants to inhale heats that are needed to create/produce steam- (a gas that comes from liquid at its boiling point) The process is called fission. Fission entails the splitting on atoms in the nuclear reactor.

The chemical formula of nitrogen dioxide is NO2. It is a brown coloured gas.
Answer:
5.96 g/cm^3
Explanation:
Corner atom = 1/8
Atoms in center = 1
Atoms in face of the cube= 1/2
Molar mass of V = 50.94 g/mol <em>(from period table)</em>
1 mole = 6.02x10^23
<em>In BCC unit cell:</em>
(8 x 1/8)+ 1=2 per 1 unit cell
<em>Mass: </em>2(50.94g)/6.02x10^23 = 1.69x10^-22 g/unit cell
305pm=(305x10^-12m÷10^-2m) x (1mL÷1cm^3)
= 2.837 x 10^-23 mL
<em>1pm=10^-12m</em>
<em>1cm=10^-2m</em>
<em>1mL=1cm^3</em>
<em></em>
density=mass/volume
density of V = 1.69x10^-22g÷2.837x10^-23mL
=5.957g/mL
=5.96g/cm^3
Answer:
Explanation:
The blow-by gases that escape past the piston rings and get into the crankcase are mostly unburned fuel-air mixture.
The fuel is largely a mixture of hydrocarbons (HCs)
.
The PCV system captures these gases and feeds them back to the cylinder for further combustion.
A. is wrong. Carbon dioxide exits through the exhaust.
C. is wrong. Most of the oxygen in the incoming air is used for combustion in the cylinders.
D is wrong. The NOx gases exit via the exhaust and are trapped by the catalytic converter.
