What is the<br> total charge of 1 proton, 1 electron, and 1 neutron?
iragen [17]

Given parameters:

Number of protons  = 1

Number of electrons = 1

Number of neutrons  = 1

unknown:

Total charge = ?

Atoms are made up of elementary particles of protons neutrons and electrons.

Protons are the positively charged particles in an atom

Electrons are the negatively charged particles

Neutrons do not carry any charges

To find the total charge on an atom; simply find the difference between the number of protons and electrons.

       Total charge  = Number of protons - number of electrons

                               = 1 - 1

       Total charge is 0

Therefore, the total charge is zero, 0

A sample of gas has a pressure of 742 torr. What is the pressure in atmospheres?
ycow [4]

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

\frac{742 torr}{1}*\frac{1 atm}{760 torr}=0.976316=0.976 atm

(torr cancels out and we're left with atm)

Hope this helps :)

1. Given the following equation:
CaHeK987 [17]

Answer:

a. C₄H₁₀/O₂    =  2:13 (example)

b. O₂/CO₂      = 13:8

c. O₂/H₂O      = 13:10

d. C₄H₁₀/CO₂ =  2:8

e. C₄H₁₀/H₂O =  2:10

Explanation:

2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O

The molar ratios are the same as the coefficients in front of the formulas.
