Answer is: <span>b) A/4B.
Chemical reaction: A + 4B </span>→ C + 3D.
from chemical reaction: n(A) : n(B) = 1 : 4.
a) if 1A reacts with 1B, there is not enough B (need 3B more).
c) if 3A react with 4B, there is not enough B (need 8B more).
d) if 4A react with 1B, there is not enough B (need 15B more).
False- water has a high specific heat, so it does not change temperature as easily.
Newton's third law (for every action, there is an equal and opposite reaction) means that in every interaction (in this case, that of the objects in the image), there is a pair of forces acting on the two interacting objects. <span>When you sit on a chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. This is embodied in the image by the two objects exerting force on each other (indicated by the arrows).</span><span>
Hope this helps.</span>
Answer:
There are two dots are present on the left side of calcium atom which represents the unpaired electrons present in the outermost shell. This structure is presented by Lewis in order to show the number of unpaired electrons in the atom.
Explanation:
Answer:
Covalent, or, elements on the right side of the ladder (on the periodic table). Covalent compounds satisfy the octet rule by sharing electrons.
