True.
No matter what, the energy given by a substance can act as energy for something else. For example, the energy exerted by wind can be used to power a windmill, which in turn can power a generator that creates electricity. Another example can be running water, which generates energy that is used to turn a water turbine, which then generates electricity from the energy that is passing through the turbine.

Answer:
The given metal is beryllium.
Explanation:
Given data:
Mass of metal = 74 g
Volume of metal = 40 cm³
Which metal is this = ?
Solution:
First of all we will calculate the density.
it is mass divided by volume.
d = m/v
d = 74 g/40 cm³
d = 1.85 g/cm³
In literature it is given that the density of beryllium is 1.85 g/cm³. Thus given metal is beryllium.
Answer:
I think its A sry if im wrong
Explanation:
Answer:
the new volume would be 1.62 L
Explanation:
stp is 0 degrees C or 273.15 K and 1atm for the pressure
22 degrees C is 295.15 K
use the combined gas law formula and solve for v2
v2=p1(v1)(t2)/p2(t1)
v2=1atm(1.2L)(295.15)/0.8atm(273.15K)
v2=1.62
Answer:
The answer to your question is B. metallic
Explanation:
Covalent bonding is a bond between two nonmetals and the difference in electronegativity is between 0 and 1.7. Sodium could not have this kind of bond because is a metal.
Ionic bonding is a bond between a metal and a nonmetal and the difference of electronegativity is higher than 1.7. Sodium can have this kind of bond it is necessary one nonmetal.
Metallic, sodium has a metallic bond because this bond is characteristic of metals.
