Answer:
Repulsive forces exist only when atoms are very close to each other. (3/14) "They [the atoms] will approach until both nuclei will simply shove each other because both of them are positive." The balance between the attraction and repulsion forces determines how close the atoms can get. The relationships between the magnitude and direction of repulsive and attractive forces. A stable state of a bond is when attractive forces balance repulsion forces. “A stable state between two atoms is when they attract each other with a force that equals the force that they repel each other.”
Answer and Explanation:
The molar mass of a substance is all of the weights from the elements combined.
So, we have the elements
CU, S, and
CU has a mass is 65
S mass is 32
O has a mass of 16, but there's 4 atoms of O, so we do 16 times 4, which is 64.
Now we add.
65 + 32 + 64 is 161.
<u>So, the answer is 160, or answer choice A.</u>

MgCl₂ & PbSO₄ is the correct product for the given double replacement reaction.
<h3>What is double displacement reaction?</h3>
In the double displacement reaction displacement of two substrate will take place among two reactants and formation of products takes place.
In the question, PbCl₂ reacts with MgSO₄ and displacement between the cations takes place and formation of MgCl₂ and insoluble precipitate PbSO₄ is formed.
Given reaction is represented as:
PbCl₂ + MgSO₄ → MgCl₂ + PbSO₄
According to the activity series, reactivity of Magnesium is more as compared to the lead atom. So lead is displaced by the magnesium atom and form the above given products.
Hence, option (3) is correct i.e. MgCl₂ & PbSO₄.

Explanation:
local grocery stores have started to use reusable bags made of a thicker and more recyclable plastic in order to be more environmentally friendly. However, often times when I or my family goes to the grocery store, we forget our reusable bags and end up buying even more bags every time we forget them. Because humans are, from what I can tell, forgetful creatures, it is likely that many other people experience the same issue. This causes me to wonder how much more plastic is being used to make the reusable bags in order to meet the demands of forgetful customers, and how many of these plastic bags are accidentally ending up in our environment when people throw extras away or simply lose them. This relates to the findings of the study in the sense that all of those “biodegradable” bags are ending up in the environment and still causing harm, even though they were designed to eliminate it, just like how the reusable grocery bags could potentially be adding more plastic to the environment when they were designed to eliminate that risk. These situations show how even though there are new and innovative designs that say they can help our problems, we can’t become blind to the fact that we haven’t completely solved them yet.
The velocity for the forward reaction equal that of the reverse reaction.
