Answer is: density doesn't affect on weigh.
Density <span>of a substance is its </span>mass<span> per unit </span>volume, <span>density is defined as mass divided by volume (d = m/V).
</span>Weight is force<span> on the object due to </span>gravity. Weight is <span>product of the </span>mass<span> of substance and the magnitude of the local </span>gravitational acceleration (<span>W = <span>mg). Feather can have larger mass and also weight.</span></span>

<span>How iron can be more dense as a feather yet more feathers can weigh more is because density and weight are two completely different things. No matter how many feathers there are it's density never changes, it's weight is able to change but not density. Therefore the density of iron is higher no matter what but may weigh less than a group of feathers.</span>

Many elements bond to carbon by exchanging electrons. true or false.
Sliva [168]
If a metal is bonded to carbon, they form ionic bonds. If a nonmetal forms a bond with carbon, they form covalent bond. Ionic bond requires metals to give away electrons to form cations and nonmetal to gain/accept electron to form anions. Covalent bond requires sharing of electrons between both elements. So if you meant exchange as in covalent bond, then no. Not many nonmetal elements form bonds with carbon as there are more metal elements in the periodic table.

What is the molar mass of Al2(SO4)3​
umka21 [38]

Answer:

The molar mass of Al_2(SO_4)_3​ is 342.145 g/mol

Explanation:

The molar mass  is stated as the “mass per unit amount of substance”of a given chemical compound  

Al_2(SO_4)_3​  is Aluminium sulphate. They easily dissolve in water. It is primarily  used as a 'coagulating agent' in the drinking water purification and also in waste and sewage water treatment plants,  

We know,

Atomic weight of Aluminium =  26.981

Atomic weight of Sulphur= 32.065

Atomic weight of  Oxygen =  15.9994

Now molar mass of  Al_2(SO_4)_3​ (Aluminium sulphate) is

=>2(26.981)+3(32.065+4(15.999))

=>53.962 +3(32.065+63.996)

=>53.962+3(96.061)

=>53.962+288.183

=>342.145

BRAINLIESTTT ASAP! PLEASE HELP ME :)
gogolik [260]

Answer:

"Heat of combustion"

Explanation:

A physical property is characteristic of a substance that can be observed or measured without changing its chemical composition, such as color, molecular weight, and volume. A chemical property can only be observed or measured by changing the chemical composition of the substance, such as reactivity, flammability and oxidation states.

Hope this helps! :)
