Answer:

Explanation:

The first two answers are the correct ones. Sometimes C can be true, but it is not a condition. Some equations produce many more products than reactants and some equations are made from more reactants than products.

The last one is normally not true, but the three equations I choose below do give D to be true. Still it does not happen all the time.

C8H18 + 12.5 O2 ===> 8CO2 + 9H20 This is the combustion equation that drives your engine. The coefficients do not add.

Same number of reactants as products.

CH4 + 2O2 ==> CO2 + 2H2O

More products than reactants.

Cu + 4HNO3 ==> Cu(NO3)2 + 2NO2 + 2H2O

More Reactants than products.

H2 + I2 ==> 2HI

Based on the periodic table why are be, bg, ca and sr in the same column/group/family?

Lesechka [4]

Answer:

The elements are in the same column/group IIA.

See the explanation below, please.

Explanation:

The elements Calcium, Strontium, Beryllium, Magnesium, Barium and Radio, belong to the group of alkaline earth metals located in group IIA of the periodic table, they require 2 electrons to complete their octet (they have 2 valence electrons). reagents than alkali metals.

Lithium and fluorine undergo ionic bonding. Using the noble gas electron configurations for each (below), please explain the pro

Slav-nsk [51]

Answer:

Lithium loses one electron to fluorine and forms ionic bond, having formula $LiF$ .

Explanation:

Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is $[He]2s^1$ .

Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is $[He]2s^22p^5$ .

<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete. <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>

Thus, the formula of calcium chloride is $LiF$ .
