10) an object has mass of 50g 500mg and 0.1g. express the total mass of the object in grams
Pavel [41]
500 mg in g :

1 g ----------- 1000 mg
? -------------- 500 mg

500 x 1 / 1000 => 0.5 g

total mass:

50 g + 0.5 g + 0.1 g => 50.6 g

Control rods are used to prevent uncontrolled chain reactions from happening inside nuclear power plants. Based on what you know
Masteriza [31]

The main idea is to prevent uncontrolled chain reactions which occurs in nuclear fission reactors. The important characteristic of a control rod should be made of a material which does not undergoes fission.

Which two factors are essential for a molecule to be considered polar? nonpolar bonds and asymmetrical structure, nonpolar bonds
timama [110]

A nonpolar molecule is entirely symmetric. For a molecule to be nonpolar, it must have at least a linear, trigonal planar, or a tetrahedra shape. However, that’s not totally enough. For the molecule to be completely symmetric, aside from having a symmetric shape, all of the atoms that are connected to the central atom must be alike. Therefore, symmetry has two components, they are the geometric arrangement of the outer atoms and whether or not they are all the same.

Fundamentally, non-uniform or it is the uniform, distribution of electrons that ascertains if a molecule is polar or nonpolar, but this distribution is established by the dispersal and distinctiveness of the atoms in a molecule.
