Answer:
3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.
Explanation:
- Double replacement reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
- The reaction between CaCl₂ and Na₃PO₄ is:
<em>3CaCl₂ + 2Na₃PO₄ → Ca₃(PO₄)₂ + 6NaCl.</em>
<em></em>
Ca replaces Na in (Na₃PO₄ ) and forming Ca₃(PO₄)₂.
Na replaces Ca in CaCl₂ and forming NaCl.
<em>So, the products of this reaction are Ca₃(PO₄)₂ and NaCl.</em>
Answer:
1 : 2
Explanation:
From the question given, we obtained the following information:
T1 = 287°C = 287 +273 = 560K
T1 = 587°C = 587 +273 =860K
V1 = V
V2 =?
V1 /T1 = V2 /T2
V/560 = V2/860
Cross multiply
V2 x 560 = 860 x V
Divide both side by 560
V2 = (860 x V) / 560
V2 = 1.54V = 2V
The ratio of initial to final volume =
V1 : V2
= V : 2V
= 1 : 2
Answer:
Magnets
Explanation:
magnets donot require tension force
If you had to find out the pressure at which a gas contained in a 3-liter container is 5 moles at 290K, what equation would you use?
Answer:
the ideal gas law equation
Explanation:
To solve this problem, I will simply apply the ideal gas law. The law is combination of Boyle's, Charles's and Avogadro's law.
Combining these laws gives;
PV = nRT
where P is the pressure
V is the volume
n is the number of moles
R is the gas constant
T is the temperature;
So;
P =
Using this equation we can find the Pressure.
Yeah, it sure does
Hope this helps!
