Upper M g (s) plus 2 upper H right arrow upper M g (a q) plus upper H subscript 2 (g).

 Mg + 2H⁺      →      Mg²⁺ +    H₂

Explanation:

The net ionic equation is the sum of the oxidation half reactions.

The half-reactions are:

 Mg   →   Mg²⁺    +   2e⁻   Oxidation half reaction

  2H⁺    +     2e⁻    →       H₂    reduction half reaction

Combining the reactions gives:

Mg + 2H⁺    +     2e⁻   →       H₂ + Mg²⁺    +   2e⁻  

Since the electrons are balanced, they cancel out of the equation,

 This leaves behind;

   Mg + 2H⁺      →      Mg²⁺ +    H₂

Answer: The number to the left of AC should be 6.

Explanation: The balanced chemical reaction is one in which the number of atoms  of each element on the reactant side must be equal to the number of atoms on product side.

The given equation A_2B + DC_3 \rightarrow AC + D_2B_3 is unbalanced as the atoms on the reactant side are not same as number of  atoms on product side. This equation is called as skeletal equation.

The balanced chemical equation is :

3A_2B + 2DC_3 \rightarrow 6AC + D_2B_3

Thus the number to the left of AC is 6.

how many grams of oxygen gas are needed to produce 10.0 grams of carbon dioxide according to the balanced equation of CH4
Alinara [238K]
Molar mass of :

O2 = 16 * 2 = 32 g/mol

CO2 = 12 + 16 * 2 = 44 g/mol

<span>Balanced chemical equation :
</span>
1 CH4 + 2 O2 = 1 CO2 + 2 H2O
               ↓              ↓
             2 moles     1 mole

2* 32 g O2 ----------> 1* 44 g CO2
     x g O2 ------------> 10.0 g CO2

44 x = 2 * 32*10.0

44 x = 640

x =  \frac{640}{44}

x = 14.54 g of O2

How many atoms are present in 7.50 mol of chlorine atoms? _
vodomira [7]

Answer:

4.52 x 10²⁴ atoms Cl

Explanation:

A mole is a name that means a certain number like a dozen means 12. 1 mole of chlorine atoms is 6.022 x 10²³ chlorine atoms. The unit conversion is 6.022 x 10²³/mol.

7.50molCl*\frac{6.022 x 10^{23} atomsCl}{1molCl} = 4.5165*10^{24} atomsCl

Round to 4.52 x 10²⁴ atoms Cl for the correct number significant figures.

as any personal information of clients, customers, employees, guests, or anyone else exposed in the incident?
Elena L [17]

Answer:

"Protecting the privacy of your employees is critical to the long term success of your business. Senior leadership, high-profile executives and their families, as well as other customer-facing employees are particularly vulnerable to targeting to bad actors when their personal information is exposed. Other potential sources of danger include disgruntled employees, ex-employees and even customers."

Hope this helps :)
