Answer: The natural gas transmission system is primarily a giant international pipeline network, consisting of large, medium, and small-sized pipes. ... If transport by pipeline is not feasible, then natural gas is usually transported in its liquefied state, which has a temperature of -162 ° C and its density is lower than waters.
Explanation: Potential energy is stored energy and the energy of position. Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy
Answer:
4.97 X 10^13 ATOMS OF Zn
Explanation:
how many atoms of zinc are required to weigh 5.4 ng
a nano gram is 10^-9 grams
Zinc has an atomic mass of 65.39 gm/moles
there is an Avogadros number of atoms in a mole
65.39 GRAMS PER MOLE
65.39 g/(6.022 X 10^23)how many atoms of zinc are required to weigh 5.4 ng
GRAMS PER ATOM
1.086 GRAMS PER 1O^22 ATOMS
1 atom of Zn weighs 1.086 X 10^9 X 1O^-22 n grm=
1,086 X 10^-13 n gm
Y tines 1.086 X 10^-13 = 5.4 n gm
Y = 5.4/ (1.086 X 10^-13) =
4.97 X 10^13 ATOMS OF Zn
CHECK
(4.97 X 10^13 ) X 65.39 gm/(6.022 X 10^23) =
5.397 X 10^-9 =
5.4 n g
Answer:
Rubidium belong to Alkaline group 1, and
Strontium belong to Alkaline group 2.
Explanation:
We know that elements are organized on the periodic table based on their properties. The statement correctly predicting and explaining the chemical reactivity of two metals is given below -Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.
Answer:
2 the mass is greater than 10.0gram
Explanation:
2 the mass is greater than 10.0gram
This defines the products, as they are formed in the reaction
