You are on the Titanic and want to find something that will float because you didn't

damaskus [11]

Find volume of pillow

L=78cm

B=55cm

H=25cm

$\\ \bull\tt\longrightarrow V=LBH$

$\\ \bull\tt\longrightarrow V=25(78)(55)$

$\\ \bull\tt\longrightarrow V=107250cm^3$

$\\ \bull\tt\longrightarrow V=10.72m^3$

Now

Mass=5.5kg

$\\ \bull\tt\longrightarrow Density=\dfrac{Mass}{Volume}$

$\\ \bull\tt\longrightarrow Density=\dfrac{5.5}{10.72}$

$\\ \bull\tt\longrightarrow Density=0.5kg/m^3$

Density of water=1000kg/m^3

As it is less than density of water it will float on water

Atoms can gain, lose, or share

Oksi-84 [34.3K]

Answer:

Atoms can gain, lose, or share electrons during a chemical change. Chemical changes do not affect the nucleus of an atom. For this reason, an atom has the ability to retain its properties or identity even if the number of electrons is different. Therefore, the atom's identity won't change.

How are chemical bonds important in metabolism?

mixas84 [53]

Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
