Coefficients are used here to balance the number of elements in the products and reactants. Coefficients are numbers that are placed in front of a chemical formulas in an equation. Hope it's useful.
Answer:
D. gravity, friction, and an applied force.
Explanation:
There are 4 forces that act on an airplane in motion and they are:
Gravity and drag:
It acts in a downward direction—toward the center of the Earth.
Lift:
It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Thrust:
It is the force that propels a flying machine in the direction of motion.
Answer:
A
Explanation:
Because the Bohr model explains the Conteplation of the Atom which consedes to the answer explaing the neutrons and electrons have a relation which makes A right.
Molar mass glucose : <span>180.1559 g/mol
</span>
number of moles:
n = mass solute / molar mass
n = 225 / 180.1559
n = 1.248 moles
therefore:
Molarity = moles solute / volume
Molarity = 1.248 / 0.825 => <span>1.513 M</span>
Explanation:
Chloroform and silver powder react with each other and exchange the ions with each other to form acetylene molecules which are also called ethyne and silver chloride. The molecule C2H2is called acetylene which is a colourless gas with no odour.
