What is $169.00 plus tax in Northern California?
That is a list of the valences of several elements.Hydrogen is +1 (and also -1, incidentally)Sodium is +1Potassium is +1Calcium is +2
1200+(tax) =1200X1.13 =1356 with tax
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
increases Ca++ (but not phosphate) reabsorption from the glomerular filtrate of kidney nephrons
failure in regulation of calcium level by parathyroid hormone.
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
Obviously,deficiency of PTH causes hypocalcaemic tetany as PTH is one of the most important regulator in maintainance of the cocentration of plasma Ca++.It increases the rate of bone resorption through potentiation of osteoclastic activity.It also increases the reabsorption of Ca++ from DCT through recruitment of more TRPV-5 channels.So,if due to any cause there is gross injury in parathyroids(mostly occurs during performing thyroidectomy operation),there is hypothyroidism followed by marked hypocalcaemia resultig in hypocalcaemic tetany.
It produces hormone parathomon. It increases the Ca level and decrease the phosphate level of bllod

Ca(OH )2 plus sulfuric acid yields water and CaSO4.
Remember the general acid equation Acid plus metal gives a salt plus hydrogen. 2HNO3(aq) + Ca(s) = Ca(NO3)2(aq) + H2(g)
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
Ca + H2SO4 = CaSO4 + H2
ca + cl2 --> cacl2
Ca + 2 HCl = CaCl2 + H2
