Answer:
It goes the crust mantle outer core and inner core. The crust is what we are standing on it has dirt, rock, stone, the mantle it has lots of silicate rocks and magnesium. The outer core has liquid nickel and iron and the inner core has solid metals
Answer:
Volume of solution = 80.5 mL
Explanation:
Given data:
Molarity of solution = 4.50 mol/L
Mass of ethanol = 16.7 g
Volume of solution = ?
Solution:
Volume will be calculated from molarity formula.
Molarity = number of moles / volume in L
Number of moles:
Number of moles = mass/molar mass
Number of moles = 16.7 g/ 46.07 g/mol
Number of moles = 0.3625 mol
Volume of solution:
Molarity = number of moles / volume in L
4.50 mol/L = 0.3625 mol / volume in L
Volume in L = 0.3625 mol /4.50 mol/L
Volume in L = 0.0805 L
Volume in mL:
0.0805 L ×1000 mL/1 L
80.5 mL
Answer: The new volume of gas is 28.5 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm (at STP)
= final pressure of gas = 102.6 kPa = 1.01 atm (1 kPa= 0.0098 atm)
= initial volume of gas = 10.0 L
= final volume of gas = ?
= initial temperature of gas = 
(STP)
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The new volume of gas is 28.5 L
These are known to be saturated.
The definition of a saturated fatty acid is that the carbon chain coming off of the acid group contains only single bonds. An unsaturated fatty acid contains at least one double bond in the carbon chain coming off of the acid group. Saturated fats are usually fats (solid at room temperature) while unsaturated fats can be oils (liquid at room temperature) this is because the single bonds in the saturated fats give the molecule a shape that can stack on another saturated fat molecule more easily which makes the melting points higher. The double bonds (usually referring to cis double bonds since trans double bonds are in trans fats) in unsaturated fats give the molecule a shape that cannot stack on another unsaturated fat molecule easily which makes the melting point lower.
