@taskmaster 90. magnesium chloride and sodium carbonate are added together.
a. write an equation for the combination of magnesium chloride and sodium carbonate. (make sure it is balanced! )
b. what type of reaction is this?
c. would a precipitate form from this combination of reactants? if so, name the compound that makes the precipitate:

A) MgCl₂(aq)+Na₂CO₃(aq)→MgCO₃(s)+2NaCl(aq)

b) double replacement reaction

c) Yes,  Magnesium carbonate forms.

I hope this helps.  Let me know if anything is unclear.

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
