Answer:
Explanation:En la tabla periódica los elementos están ordenados de forma que aquellos con propiedades químicas semejantes, se encuentren situados cerca uno de otro. Los elementos se distribuyen en filas horizontales, llamadas períodos.
Answer: the correct option is (C).
Explanation:
Covalent compounds have lower melting and boiling points due to presence of weak inter-molecular forces by which molecules are weakly associated to each other. Hence, melting and boiling of covalent compounds occurs at low temperatures.
Usually, Covalents compounds have following properties:
- They are brittle solids
- They do not conduct electricity
- They do not have rigid crystal structure.
- They exist in all states: solids, liquids and gases.
Answer:
1.05 L
Explanation:
There is some info missing I think this is the original question.
<em>A laboratory experiment requires 250 millimeters of water boiling. it also requires 100 mills of water for a cooling process. If a student performs the experiment three times, how much total water will the student need? Give your answer in liters.</em>
<em />
Step 1: Calculate the volume required for each experiment.
The volume required is the sum of the volumes used: 250 mL + 100 mL = 350 mL
Step 2: Calculate the volume required for the 3 experiments
We have to multiply the volume required for each experiment by 3.
3 × 350 mL = 1050 mL
Step 3: Convert the volume to liters
We use the relation 1 L = 1000 mL.
1050 mL × (1 L/1000 mL) = 1.05 L
