Answer:reaction, or reactants becoming products: A + B →. C + D reactants products ... CaCl2 has two Cl's because Ca is +2 charged so we need two –1 ... Due to the Law of Conservation, the number of atoms (and the mass) of each ... This is a balanced equation – same number of H and O atoms on both sides of the arrow.

Answer:

This equation is not balanced because your mass of the products is not equal to the mass of the reactants. So the correct option is no because the law of conservation of mass is not being followed. The hydrogen and chlorine atoms have different numbers of atoms in the reactants and products.

Explanation:

This is because on your reactant you have 2 Hydrogen atoms while on your product side you have four because the coefficient of 2 and the H2 multiply and make four in total. Also, on the reactant side, you have 2 chlorine and on the product side, you have 4 chlorine atoms.

A simple way to look at this would by doing this:

Equation: 2Zn + 2HCl ----- 2H2 + 2ZnCl2

So on the reactant side, you have 2 zinc atoms, 2 hydrogen atoms and 2 chlorine atoms while on the product side, you have 4 hydrogen atoms, 2 zinc atoms and 4 chlorine atoms.

Hope that helps!!

Answer:

Explanation:

identifying common genetic variants underlying chronic non-communicable diseases, but have proved to be more difficult for acute infectious diseases that represent a substantial portion of the global disease burden and are most prevalent in tropical regions. This is partly due to the practical difficulties of establishing large sample collections and reliable phenotypic datasets in resource-constrained settings, but also theoretical and methodological challenges associated with the study of pathogenic diseases in populations with high levels of genetic diversity and population structure1,2,3. The Malaria Genomic Epidemiology Network (MalariaGEN) was established in 2005 to overcome these obstacles with standardized protocols, common phenotypic definitions, agreed policies for equitable data sharing and local capacity building for genetic data analysis, enabling large collaborative studies across different countries where malaria is endemic4.

Here we extend previous work by using data collected from 11 countries to perform a comprehensive GWAS of human resistance to severe malaria (SM)
