Answer:
metallic bonding
Explanation:
Metallic bonding is bonding where electrons exist as "sea of electrons" meaning they can go anywhere in the structure and are not localized in specific place like covalent bonds are sometimes.
Answer:
B. negative charge only
Explanation:
The saying "opposites attract" is true in the case. Since the rod is positively charged, the sphere must have a negative charge to be attracted to it.
A sphere that is positively charged would be repelled from the rod, and a neutral sphere would not be attracted or repelled.
Answer:
45 mL
Explanation:
Tenemos los siguientes datos:
V = 1 L
C = 4,5% v/v
El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:
4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol
Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:
4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

Answer:
The correct answer would be - lose their native habitats are forced to migrate into new areas in search of shelter and food.
Explanation:
The removal of trees or deforestation to build a housing or city planning or development impact the birds and other animals of that area. Cutting most of the trees from the area will result in a decrease in available food, shelter, and breeding habitat.
It causes complete removal of bird species and forced them to migrate to a new place in search of places that will provide a source of shelter and food for birds.
