Answer:
The number 10,847,100 in Scientific Notation is
Explanation:
Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.
Hey there !
Molar mass KOH = <span>56.1056 g/mol
1) Number of moles :
n = m / mm
n = 25.4 / </span><span>56.1056
n =0.452 moles
Volume in liters :
985 mL / 1000 => 0.985 L
Therefore:
M = n / V
M = </span>0.452 / 0.985
=> 0.458 M
<u>The velocity and pressure of a fluid is related as follows:</u>
The speed is also called as velocity. Bernoulli’s Principle states that, higher the velocity of a fluid (means liquid or gas), the lower the pressure it exerts. The rapid motion of the fluid molecules causes the Fluid pressure. The Bernoulli equation is given as,
Where,
P – Pressure
ρ –density
v – Velocity
g – Gravitational acceleration
h - Elevation
So, when the fluid moves faster, some energy from the rapid motion of the fluid is used to move faster in the fluid’s direction of motion which results in a low pressure. Thus, the more the speed of a fluid, the lesser is the pressure ().
Answer:
Susan is right
Explanation:
Honey is a natural substance extracted from bees. Like every other natural substance, honey is a mixture of many different substances. An analysis of the so called 'pure honey' will reveal that many chemical species compose the natural substance called honey.
Hence Susan is right when she says that honey is not really pure but a mixture of substances.
