Answer:
D. recycling aluminum cans and glass bottles
Explanation:
it's the only one that makes sense because if its a short trip you should walk, you should use reusable bags, and turn off the water while brushing your teeth.
Hope this helps and have a wonderful day/night/afternoon
Copper is used in household wiring because it is a good conductor of electricity and heat. Since conductors have low resistance, therefore copper has low resistance too.
Your answer is: Good conductor or electricity and heat
Have an amazing day!
The Ph scale can tell you if a substance is an acid a base or neutral by
a Ph scale runs from a Ph of 1-14. if a substance has a Ph less than 7 (Ph<7) the substance is said to be a an acid
if a substance has a ph greater than 7 (Ph>7) the substance is said to be a base
if a substance has a Ph equal to 7(Ph=7) the substance is said to be neutral
Answer:
To speed up a reaction
Explanation:
Heat, as well as catalysts, increase the reaction rate of some chemical reactions since they cause the enzymes or reagents in charge of carrying out the transformation to products to act faster and increase their kinetic energy of reaction.
Answer:
B. How many of each atom are present in the compound
D. the simplified ratio of atoms in relation to each other
Explanation:
In a chemical formula, chemical elements or atoms are represented by a chemical symbol for example Fe for iron and Na for sodium, and the number of each atom is represented by a subscript such as CO2, where 2 is a subscript representing 2 atoms of oxygen.
A subscript represents the number of each atom in the compound and the simplified ratio of atoms in relation to each other. The simplified ratio of atoms in relation to each other means subscript shows the contribution of both the atoms in the compound, for example: N2 + 3H2 => 2NH3, it means the subscript showing the ratio or proportionate of atoms that is 2:2 for both nitrogen and hydrogen.
The subscript is always written below and to the right of the chemical symbol.
Hence, the correct answer is "B. How many of each atom are present in the compound and D. the simplified ratio of atoms in relation to each other"
