The viscosity of water will decrease as it is directly related to intermolecular forces and when intermolecular forces decrease viscosity decreases.
1. Homogeneous substance
2. Homogeneous mixture cannot be separated into their respective constituents similar to elements that cannot be separated into simpler substance (not sure)
Formula units are there in 212 grams of MgCl₂ are 830.56
Formula is the empirical of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations and it is the lowest whole number ratio of ions represented in an ionic compound
Here given data is
MgCl₂ = 212 grams
1 mole of magnesium chloride has mass = 95.211 gram and contains 6.022×10²³formula units of magnesium chloride
Here 212 grams×6.022×10²³form unit of MgCl₂/95.211 gram = 830.56

Chemical properties describe how a material will react in a chemical reaction.
Physical properties describe such as color.
volume and mass are not properties, they are amounts. Density is a physical property because it s the ratio between mass and volume and does not change with amount.
Temperature is not a property.
Calories would be a chemical property because it describes chemical bonds. Energy is stored in the chemical bonds.
Chemical properties of the cake would be that it burns, another could be that it spoils, can be digested,
If the resources run out and there is no way to get them all motors will have to be switched to solar or some other source.
