The s orbitals are spherical, while p orbitals are polar and oriented in particular directions (x, y, and z). It may be simpler to think of these two letters in terms of orbital shapes (d and f aren't described as readily).
It’s D because the other ones don’t aren’t true
You need the heat of fusion of ice to solve this problem. <span>the heat of fusion of water = 334 J/g </span><span>
the formula to solve for heat is </span>q = m·ΔH<span>f</span>
just plug the values
q= (50.0 g) (334 j/g)= 16700 joules or 16.7 Kj
Hydrogen H weight: 81
Non-metal
Hydrogen is the simplest element; an atom consists of only one proton and one electron. It is also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth--it is always combined with other elements.
period 1 group 1
Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
Geology: The science that corporates with Earth’s forceable structure.
Erosion: going through abrasion or by other substances.
Uniformitarianism: the thought that earth’s crust have been changed in the past.
Igneous Rock: Also called magmatic rock, is when the debris of lava is dried and becomes solid creating another rock called Igneous Rock.
Sedimentary Rock: These are formed over years and years of layers of minerals forming bedding also forming huge structures which are called sedimentary basins.
Metamorphic Rock: These rocks are created once several rocks are affected by high temperatures and high pressures
Rock cycle: This is called a formation under the earth by rocks in earth, which includes igneous, uplift, intrusion, erosion, deposition as sedimentary, transportation, remelting, metamorphism, and further igneous intrusion.
Magma: A fluid that has very high temperature or inside the earth’s crust there is a semi-fluid which creates hot lava and several igneous rock is made once the lava is cooled down.
Lava: Is high temperatures coming from the earth’s crust and comes out from underneath creating erosion which erupted from a volcano making very hot liquids.
