<span>A compound is a substance composed of two or more elements that are chemically combined in a fixed proportion. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. An electrolytic cell differs from a voltaic cell because an electrolytic cell requires an outside energy source for a nonspontaneous chemical reaction to occur. As electrons push each other around, the electron orbital clouds form different shapes. Scientists propose that atoms can have up to seven principle energy levels of electrons around the nucleus. This orbital diagram for nitrogen shows how electrons fill the sub-orbitals. Wave Mechanical .This is the electron configuration for the element sulfur, which has 16 electrons. We and everything around us are made of tiny groups of particles, called atoms. While atoms were once thought to be the smallest unit of matter, they are actually made up of much tinier, high-energy, negatively-charged particles circling at a crazy pace around a nucleus of positive and neutral particles. Since the outer-shell (valence) electrons control the chemical properties of a material, it would be useful to understand how they behave.</span>

How have safety concerns about chemicals changed over time?

Alex787 [66]

Answer:

C. As scientists have learned more about chemicals, they have become more aware of their dangers

Explanation:

Chemicals are substances with standard compositions, held together by chemical bonds. Chemicals can exist in different phases such as solid, liquid, and gaseous phases. Over time, with a growing understanding of chemicals, their composition, and their reaction methods, scientists now have a better knowledge of the dangers chemicals can pose. To that effect, they have created standard safety measures for those who have to work with these chemicals.

When these guidelines are strictly adhered to, the chances of suffering accidents, burns, and explosions with these chemicals are significantly reduced.

Someone please help me:

Stels [109]

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.

Sphinxa [80]

Heterogeneous-a mixture of two or more things
solution-a substance that dissolves
suspension-mixture where solid particles do not dissolve
colloid-does not settle and cannot be seperated

Heterogeneous
- tuna casserole
-chocolate chip cookies
-gelatin dessert
-green salad
Solution
-oil (?) depends
Suspension
-vinegar salad dressing
-oil (?) it could go in either catagory
Colloid
