hard because it has calcium and magnesium
Answer:
equal and opposite
Explanation:
The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object
The molar mass of a substance is the mass of one mole of that substance. Therefore, in order to calculate the mass that is present while the number of moles are known, we simply multiply the number of moles present by the molar mass. In the case of carbon dioxide, the molar mass is obtained by adding the mass of one carbon atom (12) and two oxygen atoms (32). The molar mass is 12 + 32 = 44. Therefore, the mass of carbon dioxide is 2.1 * 44 = 92.4 grams. The answer is D<span>.</span>
- Sedimentation and Decantation is the process of setting of solid particles from a liquid either to produce a concentrated slurry or to clarify a liquid containing solid particles . The solid must not be mixed with liquid. For example- sand insoluble in water
- Sublimation - In this process solid phase is directly transformed into vapour form without passing through liquid phase.This method is used in the purification of those substances which have sublimation property. At first the mixture should be sublimed before dissolution in liquid.
- EX- Iodine , naphthalene, ammonium chloride etc. Here, NH4Cl is seperated by sublimation.
- Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts. The process convert the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains.
- so, now by evaporation of the liquid solvent we finally get the salt that was dissolved in it that is NaCl.

Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.
