Magnesium oxide (chemical formula: MgO) is a compound composed of magnesium and oxygen elements. Relative molecular mass is the ratio of the mass of a substance molecule to the mass of carbon-12 isotope. It can be used to describe the size of the Magnesium oxide molecule's mass. What ...
Propionic acid, C2H5CO2H (Ka = 1.34 × 10−5), is used in the manufacture of calcium propionate, a food preservative. What is the hydronium ion concentration in a 0.698-M solution of C2H5CO2H? White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of wh...
and serum phosphorus were shown to be substantially associated with LVMI after adjustment for clinical confounding factors including age, prevalent diabetes, diuretics use, hs-CRP, albumin, and eGFR, while sex, body mass index (BMI), haemoglobin, serum calcium, and SBP were significantly associated...
Dietary and gastrointestinal (GI) problems have been frequently reported in autism spectrum disorder (ASD). However, the relative contributions of autism-linked traits to dietary and GI problems in children with ASD are poorly understood. This study firs
Transpirational water loss was determined by weighing pots at seven time points throughout the day under the prevailing temperature and RH % conditions, when VPD increased through the time course of the day. VPD was calculated from these temperature and relative humidity % data using the formula:...
