Maksim231197 [3]3 years ago
3 0
The answer is 3 loads
You have<span> 0.2 shifts per 1 load.</span>
You have<span> 5 loads per 1 shift.</span>
So you have 3 loads for 8 quarters.
0.2 x 5 = 1
1 x 3 = 3. So the answer is 3 loads.

Glucose, a common carbohydrate, is a molecule that contains the elements carbon, hydrogen, and oxygen. Complete combustion of a
lesya [120]

The formation of carbondioxide is given by equation as

C + O2 ----> CO2(g)

As per balanced equation one mole of carbondioxide is obtained from one mole of carbon

if 44 g of CO2 is formed it means it contains 12 g of carbon

if 1g of CO2 is formed it means it contains 12/44 g of carbon

if 0.528g of CO2 is formed it means it contains = 12 X 0.528 / 44 g of carbon

                                                                           = 0.144g of carbon

Similarly for water

H2 + 0.5O2 ---> H2O

so one mole of water is obtained from one mole of H2

if 18g of water is formed it means 2g H2 is present

if 1g of water is formed it means 2/18 g of H2 is present

if 0.216g of water if formed it means 2 X 0.216 / 18g of H2 is present = 0.024g of Hydrogen

In glucose we have Carbon , Hydrogen and oxygen

As given the total mass of sample = 0.360g

Mass of carbon = 0.144 , moles of carbon = 0.144 / 12 = 0.012

Mass of hydrogen = 0.024 , moles of hydrogen = 0.024 /1 = 0.024

mass of oxygen = 0.360 - (0.144+0.024) = 0.192

Moles of oxygen = 0.192 / 16 = 0.012

So mole ratio of C : H : O = 0.012 : 0.024 : 0.012 = 1:2:1

Empirical formula = CH2O

Marvin records scientific data about Lake Superior. For which property has Marvin forgotten to use an SI unit of measurement?
Illusion [34]

Answer: low temperature

Explanation:-

S.I or M.K.S is a system for defining physical units as meter, kilogram, second, ampere, kelvin or celcius, candela, and mole together with a set of prefixes to indicate multiplication or division by a power of ten for measuring length, mass, time , current, temperature and amount of substance respectively.

Given :

lake length = 563 kilometers = 563\times 10^3m

High temperature =76.5^0F

Low temperature =-6.3^0C

annual precipitation =762 mm= 762\times 10^{-3}m

Thus low temperature in units of Fahrenheit is not an S.I unit of measurement.

Give the major force between ethanol and rubbing alcohol.
insens350 [35]
The major force between ethanol and rubbing alcohol is hydrogen bond. Hydrogen bond are intermolecular force that are weaker than covalent bond but holds atoms together in a molecules. For an hydrogen bond to be formed, a molecule must contain an hydrogen atom that will be bonded to one of the most electronegative element.
