Answer:
Pressure, P = 15.4 lb/in²
Explanation:
Given that,
Force applied, F = 26.4 lb
Area of cross section, A = 1.71 in²
To find,
Pressure.
Solution,
Pressure is equal to force per unit area of cross section.
Hence, the correct option is (a) "15.4 lb/in²".
Answer:
No he will not
Explanation:
The orthoclase has a protective wall around it very similar to a cell wall that attracts eukaryotes in order to protect itself
The volume, in liters, per kg of the Himalayan pink salt would be 0.97 L
Recall that: density = mass/volume
Hence: volume = mass/density
In this case, the density of the Himalayan pink salt is 1.03 while the mass we are working with is 1 kg.
1 kg is equivalent to 1000 g
Thus: volume = 1000/1.03
= 970.87 mL
Divide by 1000 to convert to L
970.87/1000 = 0.97 L

Answer:
Potassium permanganate has a molar mass of 158.04 g/mol. This figure is obtained by adding the individual molar masses of <em><u>four oxygen atoms</u></em>, <em><u>one manganese atom</u></em> and <em><u>one potassium atom</u></em>
Explanation:
Answer:
81.8 %
Explanation:
The balanced equation for the reaction is ⇒
So to find the number of moles of we do 6.04kg ÷ 2 = 3.02 moles.
The mole ratio between and is 3:2. So to find the number of moles you do × 2 which gives you 2.0124 moles.
Then you find the mass by doing moles multiplied by Mr: 2.0124 x 17 which gives you 34.21 kg.
Then to find the percentage yield you do: x 100 = 81.82.......
Which is 81.8 %
