An alpha particle is a helium nucleus without the electrons - 2 neutrons and 2 protons.
So, all you would have to do is 2 x 55, which equals 110.
Answer:
C. 1-ethyl, 3-methylcyclohexane
(Photo for proof at the bottom.)
Explanation:
The 1-ethyl is because you start numbering from the longest branch, towards the next closest branch. Prefix "eth-" means two, there are 2 carbons in the longest branch. 3-methyl is because the next branch is at number 3, and prefix "meth-" means 1, there is 1 carbon in that chain. "Cyclo" in cyclohexane means the skeletal model is shaped like a ring, and the "hexane" means there are 6 carbons in the ring. Prefix "hex" means 6.

A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a <em>high</em> tide.
The gravitational attraction of the Moon and the inertia of the oceans cause <em>two tidal bulges </em>on opposite sides of the Earth.
B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.
C. True. The whole solar system moves around the galaxy.
D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.
E. False. The <em>mass of an object is constant</em>, but its <em>weight changes</em> according to the gravity of the planet.
F. False. To find the mass of an object, <em>divide</em> its weight by gravity.
or weight = mass × gravity
∴ <em>Mass = weight/gravity
</em>
Answer:
An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature.
