The reactants has 2 NO2 and the product has 3. So we need to make sure we have 6 on each side. 
Al + 3Fe(NO2)2 -> Fe + 2Al(NO2)3 
This leaves us with us just to balance the Fe And Al 
2Al + 3Fe(NO2)2 -> 3Fe + 2Al(NO2)3

Hope this helped :)

How many milliliters of 3.0 M H2SO4 are needed to make 450 mL of 0.10 M H2SO4?
never [62]

Answer:  97.2223 ml

Explanation:

The rule that we will use to solve this problem is:

M2*V1 = M2*V2 where:

M1 is the initial concentration = 3.5 m

V1 is the initial volume = 0.25 l = 250 ml

M2 is the final concentration = 9 m

V2 is the final volume that we need to find

Substitute with the givens in the above equation to get V2 as follows:

3.5*250 = 9*V2

V2 = <em><u>97.2223 ml</u></em>

If a lab requires each a lab group (3 students) to have 25 ml of a solution and it takes 15 grams of AgNO₃ cuprous nitrate, to m
pochemuha

Answer:

0.375 grams are needed to make 25 mL solution.

Explanation:

Mass of AgNO_3 cuprous nitrate required to make 1 l of solution = 15 g.

1 L = 1000 mL

Mass of AgNO_3 cuprous nitrate required to make 1000 mL of solution = 15 g

Mass of AgNO_3 cuprous nitrate required to make 1 mL of solution:

=\frac{15}{1000} g

Mass of AgNO_3 cuprous nitrate required to make 25 mL of solution:

=\frac{15}{1000} \times 25 g=0.375 g

0.375 grams are needed to make 25 mL solution.

Which molecule has a lewis structure that does not obey the octet rule?
Zepler [3.9K]
I believe a possible Lewis dot structure that does not obey the octet rule, where all elements are required to have 8 electrons in their outermost shell, would be the SF4 molecule.

Sulfur can contain an more than 8 electrons, in this molecule and thus has an expanded octet.

What are 2 examples of what happens when scientist do not have a standard system of measurement of the scientific community?
dolphi86 [110]

Answer:

Explanation:

The standard system of measurement is what is popularly referred to as SI unit (or international system of units). For example, the SI unit for length is basically in meters (m), which is convertible to millimeter (mm), centimeter (cm) or even kilometer (km).

If there is no standard system of measurement,

1) Scientists will not be able to compare data as every scientist will use a unit that suits him/herself which might make data incomparable as some units might be difficult to convert to other units or there conversion methods might even be debatable.

2) There might be a general lack of understanding of the research work done by a scientist/scientists in the scientific community. This is because the standard system of measurement affords scientists to communicate properly with the same or convertible units and based on 1. above, if scientists use any unit that isn't agreed upon, different/unknown/debatable units might make understanding of research works incomprehensible.
