Answer:
stationary stationary means not in motion also known as not moving
Answer:
Because there is no friction, Newton's first law states that the ball should continue to roll. (continue at a constant speed)
Explanation:
Unless acted upon by an unbalanced force, Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction.
The mass of Ca(CN)2 : 92,11 g/mol
<h3>Further explanation</h3>
Given
0.0321 moles of Ca(CN)2
Required
The mass
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol(n) = mass(m) : MW(molecular weight)
Input the value :
mass = mol x MW Ca (CN)2
mass = 0.0321 x 92,11 g/mol
mass = 2.957 g
The answer is B, since some gas molecules are much larger than others.
Answer:
The see explanation
Explanation:
In this case, we have an <u>"amine"</u> group in the dopamine structure. So, the dopamine will act as a <u>"base"</u>. A base is a substance that has the ability to <u>accept hydrogens</u>, therefore, the
will take hydrogen from the water molecule. Additionally, the water will produce the
ion and the
will be converted into
.
