Balance the 2 chemical equation below: 1) _____H2 + _____02 ---> _____H20 2) _____CH4 + _____Cl2 ---> _____CCl4 + _____HCl
sergij07 [2.7K]

Answer:

1.)    2H2  +  O2  --->  2H2O

2.)   CH4  +  4Cl2 --->  CCl4  +  4HCl

Explanation:

In order to balance the equation, you have to make sure there are the same amount of each element on both sides.

Ex (#1).  By adding the coefficients infront of H2 and H20, You now have 4 hydrogen's and 2 oxygens on the left side as well as 4 hydrogens and 2 oxygens on the right side.

Sorry if that's confusing, but hope this helps! :)

Which metal is more active than H2?<br> (1) Ag (3) Cu<br> (2) Au (4) Pb
astraxan [27]

Answer is (4) - Pb.


According to the reactivity series of elements

- the elements which are above the hydrogen are more reactive than hydrogen.

- the elements which are below the hydrogen are less reactive than hydrogen.


Among the given choices, only Pb is placed above the hydrogen in the reactivity series and rest are below the hydrogen.


Hence, Pb is more active than hydrogen.

A fish tank holds 29 gal of water. Using the density of 1.00 g/mL for water, determine the number of pounds of water in the fish
vova2212 [387]
1. Convert gallons to mL. 1 gal = 3785.4117840007 mL, multiply that by 29 and get 109776.94173602 mL.

2. Since there is one gram per every mL, there are 109776.94173602 g of water in the fish tank.

3. Convert g to pounds. 1 g = 0.0022 pounds. Multiply 109776.94173602 by 0.0022 and end up with about 241.5 pounds of water.
