Two people are playing tug of war. One person pulls to the right with 32 N of force. The other person pulls to the left with 37 N of force. How strong is the net force and in which direction?
Answer:
The net force is 5 N and to the left.
Explanation:
37 N - 32 N = 5 N and since there is a stronger pull from the rope moves towards the left so the direction of motion is left.

What is the chemical formula for Tetraphosphorous Pentachloride ?
Answer:
CH4
Explanation:
______ meters = 177 millimeters
Answer:
117 millimeters = 0.117 meters
Explanation:
This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.

Can someone help me with number 3 thanks
Answer:
Difficult Question but I would say no
Explanation:
I say no because the whole premise of a chemical reaction is the reaction to new bonds and bond losses happening due to the introduction of a new substance. If the substance hasn't changed at all, it wouldn't be a chemical reaction because their would be nothing reacting.
b) Why is aluminium extracted using electrolysis and not carbon?
Answer:
Aluminum is more reactive than carbon so it must be extracted from its compounds using electrolysis.
Explanation:
Even though aluminum is more abundant than iron in the Earth's crust, aluminum is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process.
A bottle contains 158.1 grams of lead (II) sulfate (PbSO4), used for car batteries. How many moles does it contain?
Number of moles =0.52 moles
The number of moles is defined as the ratio between given mass and molar mass.
Given:
Mass of PbSO₄ = 158.1 grams
To find:
Number of moles=?
Molar mass of PbSO₄ = 303.26 g/mol
[tex]\text{Number of moles}= \frac{\text{Given mass}}{\text{Molar mass}}\\\\\text{Number of moles}= \frac{158.1}{303.26}\\\\ \text{Number of moles}= 0.52\text{ moles}[/tex]
Thus, the number of moles it contain will be 0.52.

How would an apple, potato, and onion all taste the same?
Answer:
If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.
Explanation:
if I have a +2 oxidation number do I give up or accept electrons?
Answer:
I will give up the electrons
Explanation:
Consider the following rules:
1. An atom loses electrons if its oxidation number is positive.
2. An atom gains electrons if its oxidation number is negative.
3. An atom neither gains nor loses electrons if its atomic number is zero.
As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.
Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Match the number of neutrons to the correct isotope by studying the atomic number and mass number of each isotope. Drag the items on the left to the correct location on the right.
these are the correct answers
What is the primary difference between two different isotopes?
Answer:
Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.

I NEED HELP FAST PLEASE
*please answer correctly*
Will mark brainliest thank you!!
Answer:
Explanation:
Using Charles Law ,
[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]
Using this formula we have ,
V1= 200cm^3
T1=40+273.15 = 313.15 K
T2 = 100+273.15 = 373.15 k
V2= ?
Hence using above formula simplify it we will get ,
V2 = 238.3 cm^3
