The name that I found is Silicate
Answer:
Explanation:
Hydrocarbon:
a = An organic compound made up of only carbon and hydrogen.
Such as alkane, alkene, alkyne.
Cyclic hydrocarbon:
c = Carbon chain that form rings.
Such as benzene, cyclo heptane etc
Isomers:
d = Compounds with same molecular formula and different structural formula.
Alkanes:
e = refers to saturated hydrocarbons, no matter the shape
such as methane, ethane, propane etc.
Alkene:
f = Any hydrocarbon that have at lest one carbon carbon double bond.
such as ethene, propene, butene
Saturated hydrocarbons:
b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed
such alkanes.
Answer:
The identities of the reactants and the products and the exact number of molecules of each one that is absorbed or generated are given by a balanced chemical equation.
Explanation:
The beginning compound(s)-reactants-on the left and the final compound(s)-products-on the right, divided by an arrow, are shown by a chemical equation.
A ball on the ground is the answer
Answer:
0.7 moles of Ca(OH)₂ are produced.
Mass of hydrogen gas = 1.4 g
Explanation:
Given data:
Mass of water = 25.0 g
Mass of hydrogen gas produced = ?
Number of moles of Ca(OH)₂ formed = ?
Solution:
Chemical equation:
Ca + 2H₂O → Ca(OH)₂ + H₂
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 25.0 g/ 18 g/mol
Number of moles = 1.4 mol
Now we will compare the moles of water with hydrogen:
H₂O : H₂
2 : 1
1.4 : 1/2×1.4 = 0.7 mol
Mass of hydrogen gas produced:
Mass = number of moles × molar mass
Mass = 0.7 mol × 2 g/mol
Mass = 1.4 g
Now we will compare the moles of water and Ca(OH)₂
H₂O : Ca(OH)₂
2 : 1
1.4 : 1/2×1.4 = 0.7 mol
Thus, 0.7 moles of Ca(OH)₂ are produced.
