Answer is 1 atm = 760 mm Hg.
There are many units which are used to measure the pressure. Examples are atm, Pascal (Pa), torr, mm Hg and bar.
Although there are many units, the SI unit is Pascal (Pa). The relationship between those units as follows;
1 atm = 101325 Pa = 1.01325 bar = 760 mm Hg = 760 torr.

erosion is the term that refers to the process by which land is worn away by natural forces or human activity.
Answer:
8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are contained in 1 mole of the compound, 3.26*10²⁵ molecules are contained in how many moles of the compound?
amount of moles= 54.12
Molar mass is the mass of one mole of a substance, which can be an element or a compound. Being the molar mass of the compound Mg(NO₃)₂ 148.3 g/mole, so 54.12 moles of the compound contains 8025.996 grams.
<u><em>8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.</em></u>
Your answer is D it decreases then increases.
Answer:
Calcium chloride (CaCl2) would help me eat my ice cream faster
Explanation:
Addition of salt to ice melts the lowers the freezing temperature of the ice thus melting the ice easily
Adding calcium chloride to my ice cream would help me eat it faster because the melting point of calcium chloride (772°C) is lower than that of sodium chloride (melting point is 801°C). Calcium chloride would melt my ice cream faster because of its lower melting point
