Answer:
A rock fragment, in sedimentary geology, is a sand-sized particle or sand grain that is made up of multiple grains that are connected on the grain scale. These can include grains which are sand-sized themselves (a granitic rock fragment), or finer-grained materials (shale fragments). at least thats what i thought u were asking
Explanation:
Explanation:
The Chemical Equations are;
H2CO3 --> H2O + CO2
8Cu + S₈ --> 8 Cus
BaCO3 --> BaO + CO2
P₄ + 502 --> 2P205
KCIO3 --> KCI + O2
8Fe + S₈ --> 8Fes
The Reactions are;
Synthesis Reaction
Decomposition Reaction
A synthesis reaction occurs when two atoms or molecules react to form a different molecule or compound.
A decomposition reaction; a compound breaks into two or more products.
H2CO3 --> H2O + CO2 (Decomposition reaction)
8Cu + S₈ --> 8 CuS (Synthesis reaction)
BaCO3 --> BaO + CO2 (Decomposition reaction)
P₄ + 502 --> 2P205 (Synthesis reaction)
KCIO3 --> KCI + O2 (Decomposition reaction)
8Fe + S₈ --> 8Fes (Synthesis Reaction)
Answer:
Mass = 36.38 g
Explanation:
Given data:
Mass of hydrogen = 30.0 g
Mass of nitrogen = 30.0 g
Theoretical yield of reaction = ?
Mass of ammonia = ?
Chemical equation:
N₂+ 3H₂ → 2NH₃
Number of moles of N₂:
Number of moles = Mass /molar mass
Number of moles = 30 g / 28 g/mol
Number of moles = 1.07 mol
Number of moles of H₂:
Number of moles = Mass /molar mass
Number of moles = 30 g / 2g/mol
Number of moles = 15 mol
Now we will compare the moles of NH₃ with hydrogen and nitrogen .
H₂ : NH₃
3 : 2
15 : 2/3×15= 10 mol
N₂ : NH₃
1 : 2
1.07 : 2 × 1.07= 2.14 mol
The number of moles of NH₃ produced by nitrogen are less it will be limiting reactant.
Mass of ammonia:
Mass of NH₃ = moles × molar mass
Mass =2.14 mol × 17 g/mol
Mass = 36.38 g
Answer: A substance that produces hydroxide ions when placed in water is base.
Explanation:
Bases are the substance:
- Which gives negatively charged hydroxide() ions in aqueous solution.
- Which have pH value ranging from 7 to 14.
Where as acid gives positively charged hydronium ion() in aqueous solution.
