Answer:HNO3 + NaOH = NaNO3 + H2O is a neutralization reaction (also a double displacement reaction). The strong acid (HNO3) and strong base react to produce a salt (NaNO3) and water (H2O).Type of Chemical Reaction: For this reaction we have a neutralization reaction. Balancing Strategies: Here is a neutralization reaction. The HNO3 and NaOH combined and form a salt and water.
hope this helps have a nice night ❤️
Explanation:
Answer:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
Explanation:
H₂²⁺(aq) + O₂²⁻(aq) + Mg²⁺(aq) + SO₃²⁻(aq) → Mg²⁺(aq) + SO²⁻₄(aq) + H₂O(l)
A careful observation of the equation above, shows that the equation is already balanced.
To obtain the net ionic equation, we simply cancel Mg²⁺ from both side of the equation as shown below:
H₂²⁺(aq) + O₂²⁻(aq) + SO₃²⁻(aq) → SO²⁻₄(aq) + H₂O(l)
PV = nRT
Where:
P = pressure in atm = 700/760 = 0.9211atm
V = volume = 8.29L
R = gas constant, 0.08206 atm-L/mol-K
T = temperature in Kelvin = 200 + 273 = 473
n = numbers of moles = Mass/molar mass
mass of the compound = 30.5
we can rewrite the equation above as
PV = (Mass)/(Molar mass) * RT
Answer:
5 atoms
Explanation:
1 calcium, 2 oxygen and 2 hydrogen makes for a total of 5 atoms in 1 molecule.
Answer:
The mass of butter is 1849 g.
Explanation:
Given data:
Specific gravity of butter = 0.86
Volume = 2.15 L
Mass = ?
Solution:
Specific gravity of a substance is the ratio of density of substance divided by the density of water.
Thus the density of butter is 0.86 g/mL
Formula:
Conversion from L to mL
2.15 /1000 = 2150 mL
d = m/v
0.86 g/mL = m/2150 mL
m = 1849 g
Thus the mass of butter is 1849 g.
