What charge does an object have that has lost an electron or electrons?

Chemistry
1 answer:
Free_Kalibri [48]3 years ago
5 0
Assuming that the object started in the ground state, any object that has lost one or more electrons would have a positive change because there would be more protons than electrons present. Therefore, the positive charge of the protons would preside over the negative change of the electrons.  

Hope this helps.

Which of the following refers to a situation in which the use of harmful gas emissions is balanced by the replenishing of renewa
nignag [31]

Answer:

carbon neutral

Explanation:

Carbon neutral is a term which signifies the implementation of policies by organizations, governments, businesses e.t.c to remove as much carbon from the environment as they add to it.

Carbon dioxide is one of the harmful gases produced during the combustion of fossil fuels. It's anomalous concentration in the earth's atmosphere can lead to devastating effects on our planets. To reduce the daily release of this greenhouse gas, an alternate use of renewable energy sources would provide a better solution towards our reliance on internal combustion engines that release carbon dioxide into the atmosphere. For example, solar farms can produce clean and renewable energy that would not release any carbon dioxide in the atmosphere.

The density of no2 in a 3.50 l tank at 780.0 torr and 37.0 °c is __________ g/l.
oee [108]
We assume that the given gas, NO2, is an ideal gas such that we will be able to use the equation,
                          n/V = P/RT
where n is the number of moles, V is volume, P is pressure, R is gas constant, and T is temperature in kelvin. Substituting the known values,
                        n/V = (1 atm) / (37 + 273)(0.0821 L.atm/mol.K)
                                       n/V = 0.039 mol/L
Converting this to density by multiplying the value with the molar mass,
                               density = (0.039 mol/L) x (46 g/mol) = 1.8 g/L

Write the equilibrium constant expression for this reaction: CH3OH (aq)+Cl-(aq)-&gt; CH3Cl(aq)+OH-(aq)
bulgar [2K]

Answer: K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients. Pure solids are assumed to have a concentration of 1.

The given balanced equilibrium reaction is:

 CH_3OH(aq)+Cl^-(aq)\rightleftharpoons CH_3Cl(aq)+OH^-(aq)

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}

Thus the equilibrium constant expression for this reaction is K_c=\frac{[CH_3Cl]\times [OH^-]}{[CH_3OH]\times [Cl^-]}
