Answer:
MgCl₂(aq) + Al₂(CO₃)₂(aq) --> MgCO₃(s) + AlCl₃(aq)
Explanation:
Magnesium Chloride - MgCl₂
Aluminium Carbonate - Al₂(CO₃)₃
Magnesium carbonate - MgCO₃
Aluminium Chloride - AlCl₃
The equation of this reaction is given as;
MgCl₂(aq) + Al₂(CO₃)₃(aq) --> MgCO₃(s) + AlCl₃(aq)
Explanation:
Hi for this one u just need to remember and use the equation.
then u find mr of potassium which is 39.1.
then u do
you get the answer as 0.5115 write ur answer to 3 significant figures which will be 0.512 moles .
hope this helps :)
It occurs in the chloroplast. Thats why only plant cells have chloroplasts.
Answer: We need true value to find out who is more accurate.
Explanation:
Precision refers to the closeness of two or more measurements to each other.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If you weigh a given substance five times and you get 3.0 kg each time. Then the measurement is very precise.
For Example: If the mass of a substance is 3.0 kg and one person weighed 3.05 kg and another person weighed 3.2 kg. Then, the weight measured by first person is more accurate.
According to the question:
Density measured by Mary = 2.226 g
/ml
Density measured by Joseph= 2.335 g
/ml
As, the standard or known value is not given, we can not know which student’s value is more accurate
Yes, Ionic bonds do not share electrons. Polar covalent bonds share electrons they just share them unevenly due to the polarity.
