I need confimation that I have correctly balanced the equation,appropriate oxidation states, and corresponding losing/gainingelectrons. I appreciate your time & effort!

A.

Ox #:

0 +2 +5-2 +2 -1 0

2Mg + Zn(NO₃)₂ --> 2Mg(No₃) + Zn

Losing: Mg loseselectrons when it goes from 0 to a +2 charge.

Gaining: Zngains electrons when it goes from +2 to 0.

Ox #:

0 +2 +5 -2 +2 -1 0

2Mg + Cu (NO₃)₂ --> 2Mg(No₃) + Cu

Losing: Mg loseselectrons when it goes from 0 to a +2 charge.

Gaining: Cugains electrons when it goes from +2 to 0.

Ox #:

0 +2 +5-2 +2 -1 0

2Mg + Pb(NO₃)₂ --> 2Mg(No₃)+ Pb

Losing: Mg loseselectrons when it goes from 0 to a +2 charge.

Gaining: Pbgains electrons when it goes from +2 to 0.

Thank you! (:

Java is a popular programming language, created in 1995.

It is owned by Oracle, and more than 3 billiondevices run Java.

It is used for:

• Mobile applications (specially Android apps)
• Desktop applications
• Web applications
• Web servers and application servers
• Games
• Database connection
• And much, much more!

• Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
• It is one of the most popular programming language in the world
• It has a large demand in the current job market
• It is easy to learn and simple to use
• It is open-source and free
• It is secure, fast and powerful
• It has a huge community support (tens of millions of developers)
• Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs
• As Java is close to C++ and C#, it makes it easy for programmers to switch to Java or vice versa
