A vacuum: the motor starts the fan that causes the vacuum to have suction and the motor is what moves the bristles
A blender: the motor is what makes the blade spin
Hope I helped!
Hey there !
We know that
Atomic number , z = number of n+number of e
=> Z = 38+28 = 66
Hence the answer is B)Nickel-66
I hope this helps you:)
Have a good day ;)
Answer:
The Earth's magnetic field intensity is roughly between 25,000 - 65,000 north magnetic pole is 86.50°N and 164.04°E and the south magnetic pole is 64.07°S and 135.88°E
The molar mass of the compound is 68 g/mol.
<h3>What is the molar mass?</h3>
The Osmotic pressure can be obtained from the relationship;
π= iCRT
π= osmotic pressure = 28.1 mmHg or 0.037 atm
i = Vant Hoff factor = 1
C = concentration = ?
R = gas constant = 0.082 atmLK-1Mol
T = temperature = 20°c + 273 = 293 K
C = π/iRT
C = 0.037/1 * 0.082 * 293
C = 0.0015 M
Now;
Number of moles = C/V = 0.0015/100 * 10^-3
= 0.015 moles
Number of moles = mass/molar mass
Molar mass = mass/Number of moles = 0. 102 g/ 0.015 moles = 68 g/mol

The crushed tablets would stop bubbling/fuzzing first because it has a smaller surface area which means that it would dissolve before the uncrushed tablets which has a larger surface area.
